PS60C Heavy-Duty CNC Wire-Cut EDM Machine for Oversized Workpieces

Modern mold manufacturing, aerospace production, heavy machinery, and precision component processing increasingly depend on machining systems that can combine large working capacity with reliable dimensional accuracy. Oversized workpieces are especially demanding because they require more than a large table. They also require a rigid machine structure, stable wire tension, accurate motion control, efficient flushing, dependable electrical discharge performance, and a control system capable of maintaining quality throughout long machining cycles.

The PS60C medium-speed wire-cut electrical discharge machining machine is designed for these requirements. As the largest high-end model in the PS-C series, it is engineered for large and heavy workpieces, thick conductive materials, complex profiles, and applications where stable cutting performance is essential. Its worktable, cutting envelope, load capacity, wire-guiding system, electrical architecture, and optional customization capabilities are configured to support demanding industrial production.

Unlike a conventional cutting machine that depends primarily on mechanical contact, a wire-cut EDM machine removes conductive material through controlled electrical discharges between a continuously moving electrode wire and the workpiece. This non-contact process makes it possible to cut hardened steel, carbide, alloys, and other conductive materials after heat treatment. The PS60C extends this capability to workpieces that are too large, too heavy, or too complex for many standard medium-sized wire EDM machines.

Taizhou Xinchengyang Machinery Manufacturing Co., Ltd. combines equipment development, mechanical manufacturing, electrical integration, testing, and customer-specific engineering. Its experience in wire-cut EDM production allows the PS60C to be positioned not simply as a large machine tool, but as a complete machining solution for users who require capacity, precision, repeatability, and long-term operational stability.

PS60C Heavy-Duty CNC Wire Cut EDM Machine for Oversized Workpieces

1. The Role of Large-Format Wire EDM in Precision Manufacturing

Wire-cut EDM is widely used when a component requires intricate contours, narrow slots, sharp internal corners, small radii, or high dimensional consistency. Because the electrode wire does not mechanically contact the workpiece, cutting forces are extremely low compared with milling, sawing, or conventional broaching. This is a major advantage when machining delicate structures, thin sections, hardened materials, or complex profiles that could deform under mechanical pressure.

However, the benefits of wire EDM can be difficult to realize when the workpiece exceeds the capacity of an ordinary machine. A large component may require a greater X-axis and Y-axis travel, a wider processing slot, higher table loading, deeper cutting capability, and a wire frame that remains stable across a larger working area. If any of these elements is undersized, operators may face additional setups, inaccurate repositioning, excessive vibration, or limitations in part geometry.

The PS60C addresses these problems with an X-axis travel of 600 mm and a Y-axis travel of 800 mm. Its standard worktable measures 840 × 1,160 mm, while the processing slot measures 840 × 1,250 mm. The maximum rated worktable load is 800 kg, and the maximum cutting thickness listed for the PS60C is 430 mm. These specifications place the machine in a specialized category for large molds, heavy industrial components, aerospace parts, and other oversized conductive workpieces.

Large-format capacity also improves production planning. A manufacturer may be able to cut several smaller components in one setup, process a complete mold insert without dividing it into sections, or machine a large profile without repeated clamping and alignment. Reducing the number of setups can lower handling time, decrease the risk of positioning errors, and improve overall process consistency.

2. Main Advantages of the PS60C

2.1 Extra-Large Working Capacity

The principal advantage of the PS60C is its ability to accommodate large and heavy workpieces while retaining the control features expected from a precision wire EDM system. The 600 × 800 mm XY travel provides a generous machining envelope for oversized parts. The worktable and processing slot are also designed to support components that cannot be conveniently placed on smaller wire-cut machines.

Large capacity is valuable in many situations. A mold manufacturer may need to cut a complete die plate, a large insert, or a heavy cavity component. An aerospace supplier may need to process structural parts with complex contours and strict dimensional requirements. A heavy-equipment producer may require profiles in large plates or hardened components that cannot be handled efficiently by standard machines.

The PS60C can also be configured for specific workpiece dimensions. Through customization, the worktable size, effective cutting depth, power supply, cutting modes, and automation functions can be adapted to a customer’s production environment. This flexibility helps prevent the common problem of purchasing a machine that is large in one direction but unsuitable in another.

2.2 High Load Capacity

A maximum worktable load of 800 kg enables the PS60C to process substantially heavier components than small and medium wire EDM machines. High load capacity is not only a matter of supporting weight. The machine structure must also preserve geometric accuracy while the table carries the workpiece and moves through the cutting cycle.

The PS60C uses a high-strength HT250 cast structure and a T-shaped bed design. In contrast to a simple strip-shaped bed, the T-shaped arrangement keeps table movement within the support boundaries of the base. This helps reduce deformation and improves long-term stability. The use of resin sand casting and aging treatment further supports structural rigidity and the retention of mechanical accuracy.

For users, a rigid machine structure offers several practical benefits. It reduces the likelihood of vibration during wire movement, supports more stable flushing conditions, improves contour consistency, and helps maintain accuracy during lengthy operations. A stable structure is particularly important when the machine is cutting thick material or when the machining process includes multiple finishing passes.

2.3 Large Cutting Thickness

The PS60C has a listed maximum cutting thickness of 430 mm. This capability allows it to work with thick plates, large mold components, and heavy conductive materials that would exceed the depth limitations of many conventional wire-cut EDM systems.

Cutting thick workpieces requires careful control of wire alignment, dielectric flushing, discharge energy, and wire tension. As cutting depth increases, the electrode wire is exposed to greater forces from flushing flow and discharge activity. Any instability can influence perpendicularity, surface finish, or wire-breakage frequency. The PS60C responds to these challenges through its constant-tension mechanism, precision guide system, high-pressure water circulation, and programmable control functions.

Product materials also contain a separate FAQ reference to a PS60 configuration with a 350 mm maximum cutting thickness and a 600 kg load capacity. Because the PS-C series includes multiple models, users should verify the exact model designation and final technical configuration in the quotation and acceptance documents. The PS60C specification table identifies 430 mm and 800 kg for the PS60C itself.

2.4 Precision Motion Control

The PS60C is equipped with a four-axis linkage system covering X, Y, U, and V. The X and Y axes control the main worktable movement, while the U and V axes support taper cutting. The taper device uses linear guides and ball screws, and the standard U and V travel is 60 × 60 mm. The listed maximum cutting taper is ±6° over 80 mm.

Linear guides and ball screws provide controlled, low-friction motion and support repeatable positioning. The machine also uses grating scales for real-time, full-stroke position monitoring of the worktable. This feedback arrangement helps the control system track actual position rather than relying only on motor rotation or theoretical screw displacement.

The listed processing accuracy for the test piece is 0.01 mm, while the product information also describes linear cutting accuracy of 0.003 mm. These figures refer to different evaluation descriptions and should be interpreted according to the applicable test conditions, workpiece material, cutting mode, thermal conditions, and measurement standard. In practical production, final accuracy depends on setup quality, wire condition, flushing, compensation, temperature, and the number of finishing passes.

2.5 Stable Multi-Pass Cutting

Medium-speed wire EDM differs from a basic single-pass cutting process because it can use multiple passes to improve surface quality and dimensional control. The first pass removes most of the material efficiently. Subsequent passes reduce the remaining allowance and refine the cutting surface.

For mold steel, hardened alloys, and cemented carbide, multi-pass cutting can reduce the surface altered layer and improve the consistency of the finished contour. It also helps the machine balance productivity and precision. Rough cutting parameters can prioritize material removal, while finishing parameters can prioritize surface roughness, corner quality, and geometric accuracy.

The PS60C lists a maximum cutting efficiency of approximately 10,000 to 16,000 mm² per hour and an optimal multi-cut surface roughness of Ra ≤ 1.2 μm under specified test conditions. These figures are useful for production planning, but actual results vary according to material grade, thickness, wire diameter, power settings, flushing, workpiece stability, and required finish.

3. Electrical Discharge and Power Supply Technology

The performance of a wire EDM machine depends heavily on its power supply. Electrical discharges must remove material effectively without causing excessive electrode wear, unstable arcing, poor surface quality, or unnecessary energy consumption. For this reason, the PS60C uses an advanced pulse power supply designed to balance processing speed, wire wear, surface finish, and energy efficiency.

The machine is described as using a patented, environmentally conscious pulse power system. Its operating objective is to achieve low electrode wear, high cutting speed, reduced surface roughness, and efficient electrical use. The full product series is available with a high-speed power supply or a nanosecond power supply as a standard configuration according to the stated product information.

Pulse control is especially important for thick-section machining. When the wire travels through a deep cut, the discharge gap must remain stable along the cutting path. Excessive discharge energy can produce undesirable surface effects or increase wire failure. Insufficient energy can lower productivity. An intelligent power supply allows parameters to be adjusted for roughing and finishing stages, helping the machine maintain a practical balance between speed and quality.

The system is rated with a maximum processing current of 6 A and an electrical capacity of 2.5 kVA. The standard power supply requirement is listed as 3N 380 V ±10 percent. Electrical installation should be reviewed in advance by qualified personnel to confirm local voltage, grounding, protection, ventilation, and compliance requirements.

Imported frequency converters support smooth directional switching in the wire drive system. Smooth reversing reduces shock loads on mechanical components and contributes to longer service life. Stable wire movement also improves the consistency of discharge conditions, particularly during long-duration cutting operations.

4. Constant-Tension Wire Management

Electrode wire tension is one of the most important variables in wire EDM. If the wire becomes too loose, it may vibrate, deviate from the programmed path, or produce inaccurate corners and tapered surfaces. If the tension is excessive or changes abruptly, wire breakage and mechanical wear may increase.

The PS60C uses an adaptive constant-tension wire-tightening mechanism. Unlike simple weight-based tensioning systems, which may respond slowly to changes in wire tension, the adaptive mechanism is intended to react more effectively to fluctuations. This improves the stability of the wire during high-speed reciprocation and helps maintain consistent cutting conditions.

Constant tension is particularly valuable in large and deep workpieces. Long cutting paths, heavy flushing flow, and taper cutting can all influence wire behavior. By controlling these variations, the wire frame can support better perpendicularity, more consistent kerf geometry, and lower risk of wire vibration.

The machine also incorporates an automatic double-sided tightening mechanism. This design helps prevent molybdenum wire vibration and one-sided loosening. The combination of automatic tensioning and stable guiding can reduce the need for frequent manual correction, improve operator convenience, and support repeatable production.

The wire feed system includes a maximum wire drum travel of 180 mm, a wire feed speed of 1 to 11 m/s under frequency control, and approximately 320 m of wire storage length. The standard electrode wire diameter is listed as Φ0.18 mm with a wire guider. These specifications provide a practical foundation for continuous machining and controlled wire movement.

4.1 Guide Wheel Design

The PS60C uses a waterproof φ40 single-sided gemstone guide wheel. The guide wheel is designed for easy threading, long service life, and precision wire guidance. Because guide wheel condition directly influences wire path stability, a wear-resistant guide system is important for maintaining cutting accuracy over time.

The main guide wheel is also designed for convenient replacement. Easy replacement reduces maintenance time and allows operators to restore the machine to normal operating condition without complicated disassembly. Regular inspection remains essential because guide wheel wear can affect wire position, surface quality, perpendicularity, and the risk of wire breakage.

4.2 Automatic Threading

One-touch automatic threading reduces manual labor and makes the initial setup or rethreading process more convenient. This feature is useful when a wire breaks, when the workpiece must be repositioned, or when the machine is prepared for a new cutting program.

Reducing manual threading work can also improve safety. Operators spend less time reaching into the working area and less time handling fine electrode wire. In production environments with frequent job changes, automatic threading can contribute to higher equipment utilization.

5. Taper Cutting and Adjustable Wire Guides

Taper cutting enables the machine to produce sloped surfaces, angled profiles, and components whose upper and lower contours differ. This capability is important in mold inserts, punches, dies, precision mechanical parts, and specialized tooling.

The PS60C uses U and V axes for taper control. The taper mechanism is equipped with P-grade linear guides, and linear guide and ball screw combinations are available for the U and V system. The standard UV travel is 60 × 60 mm, while the listed maximum taper is ±6° over an 80 mm cutting height.

The machine information also identifies CNC U and V stroke configurations of 400 × 400 mm for ±30° and 590 × 590 mm for ±45° in the machine performance section. Since taper capability can vary according to configuration, cutting height, guide arrangement, and workpiece geometry, customers should confirm the required taper angle and effective travel during technical selection.

A liftable gemstone wire guide is available as an important practical feature. Bringing the wire guide closer to the workpiece surface can reduce wire vibration and improve cutting accuracy and surface finish. The adjustable guide also allows the cutting height range to be changed without rethreading the wire, which makes manual operation more efficient.

For a manufacturer producing parts with different thicknesses, this feature can reduce setup time. It also provides greater flexibility when the same machine must process both standard plate work and deeper components. The combination of adjustable guiding, constant wire tension, and controlled U/V motion supports more reliable taper machining.

6. Mechanical Structure and Manufacturing Quality

A large wire EDM machine must remain stable under load, during reciprocating movement, and throughout long operating cycles. The PS60C therefore relies on a robust cast structure rather than a lightweight frame. High-strength resin sand castings are used to improve rigidity and dimensional stability.

The HT250 castings provide a strong base for the machine body, worktable, and wire frame. Aging treatment is applied to reduce the risk of dimensional change caused by residual casting stress. This is particularly important for large machine tools because even small structural changes can affect alignment over a large travel range.

The T-shaped bed supports the worktable within the boundaries of the base. This arrangement helps distribute load and reduce deformation. Stable support is essential when the table carries a workpiece weighing hundreds of kilograms. It also helps preserve the relationship between the worktable, guide system, wire frame, and cutting zone.

All motion mechanisms use imported EZO bearings, according to the product information. High-quality bearings help reduce friction and support smooth movement. The machine also uses high-precision linear guides and ball screws from Taiwan-based suppliers, together with Panasonic servo motors for selected drive configurations.

The standard XY drive is identified as stepper-based, while AC servo drives are available as an option. Users who require higher dynamic response, advanced interpolation, or increased repeatability may select the servo configuration according to their production requirements. The appropriate drive system should be determined based on part size, cutting cycle, accuracy targets, and automation needs.

7. Intelligent Control and Programming

The PS60C uses a professional industrial control computer designed for stable long-term operation. The control system supports the generation and execution of CNC programs and provides interfaces such as LAN and USB for data exchange.

The listed programming system is X8 or AUTOCUT, with CAXA CAM2019 or TCAM available as optional solutions. These systems help operators prepare cutting programs, manage geometry, and simplify the generation of G-code. An accessible programming environment is particularly valuable when the machine is used for complex profiles, taper cutting, multi-pass operations, and frequent production changes.

The controller supports four-axis linkage across X, Y, U, and V. This allows the machine to coordinate main contour movement with taper compensation. Accurate coordination between these axes is essential when the top and bottom profiles of a workpiece are different or when a controlled inclination is required.

LAN and USB interfaces simplify the transfer of programs and production data. They can also support practical shop-floor workflows in which programs are prepared on an engineering workstation and then sent to the machine. Data management procedures should be implemented to protect approved programs, control revisions, and prevent accidental use of outdated files.

An industrial control computer is also advantageous in a production environment because it is designed for continuous operation. Stable control hardware reduces the risk of unexpected interruptions and supports more predictable machining schedules. Technical support from the manufacturer can further assist with program creation, parameter adjustment, and troubleshooting.

8. Working Fluid, Flushing, and Clean Operation

Effective dielectric flushing is necessary for removing eroded particles from the cutting gap and maintaining stable discharge conditions. If debris accumulates in the gap, short circuits, unstable discharges, reduced cutting speed, or poor surface quality may result.

The PS60C includes automatic tracking water spraying during the cutting process. This helps direct working fluid toward the cutting area as the machine follows the programmed contour. Automatic water control can improve flushing consistency and reduce the need for constant operator intervention.

The high-pressure water tank has a listed capacity of 80 liters and uses a paper core filter. Regular filter inspection and replacement are important for keeping the fluid clean. Dirty or blocked filtration can reduce flow, affect flushing pressure, increase pump load, and influence cutting stability.

The machine incorporates an anti-splash design intended to reduce working-fluid splatter and keep the processing area cleaner. A cleaner work environment improves visibility, reduces cleanup time, and helps protect nearby electrical and mechanical components. Operators should still follow proper fluid management, spill control, and maintenance procedures.

Working fluid quality also affects wire life and surface finish. The fluid should be maintained according to the manufacturer’s recommendations, including concentration, cleanliness, temperature, and replacement intervals. Inadequate fluid management can offset the benefits of a high-performance power supply and precision motion system.

9. Manufacturing and Quality Assurance Capabilities

Taizhou Xinchengyang Machinery Manufacturing Co., Ltd. is a specialized manufacturer of EDM equipment and related special-processing technologies. Its capabilities cover product research and development, mechanical design, machining, assembly, electrical integration, testing, and technical support.

The company operates with advanced processing equipment and comprehensive testing methods. Each machine tool undergoes positioning accuracy testing before delivery. This process is intended to verify the relationship between programmed motion and actual machine movement and to confirm that the completed machine meets the applicable quality requirements.

Manufacturing a large wire EDM machine requires coordination among many disciplines. The casting must be stable, guideways must be aligned, ball screws must be installed accurately, electrical wiring must be protected, and the control system must be tested under practical operating conditions. A problem in any one area can reduce the performance of the complete machine.

The company’s long-term experience in wire cutting began in 1999, while the POOSN brand originated in 2003. Cooperation with Bingfeng CNC in 2007 supported market development, and the company was recognized as an Advanced Unit for Quality and Reputation in 2009. Taizhou Xinchengyang Machinery Manufacturing Co., Ltd. was established in 2017 with registered capital of 60 million yuan and its own factory. In 2018, it obtained a patent related to a fully automatic CNC machine tool using plate-type winding and suction-type adhesive technology. In 2021, it was recognized as a High-Tech Enterprise in Taizhou.

This history demonstrates continued investment in wire EDM development rather than dependence on a single standardized machine model. The product range includes PS-C and DK77-BC medium-speed wire-cut EDM machines, DK77-A and DK77-B high-speed wire-cut EDM machines, and DK77-D large-taper wire-cut EDM machines.

The company’s products are sold throughout China, with selected models exported to Southeast Asia, West Asia, Europe, and the Americas. International use requires attention to local electrical standards, installation conditions, operator training, and service arrangements. The company provides technical support to help customers establish operating and maintenance procedures after delivery.

10. Customization for Special Applications

Oversized workpieces are rarely identical from one customer to another. One user may need a greater table length, while another may require deeper cutting, a special power supply, a customized clamping arrangement, or an automated production sequence. The PS60C is therefore offered with customization options for special applications.

Physical customization can include worktable dimensions, effective machining area, cutting depth, fixturing schemes, and machine configuration. These changes should be evaluated in relation to structural rigidity, fluid circulation, wire path, safety clearance, transportation, and installation requirements.

Electrical and software customization may include special discharge parameters, unique cutting modes, automation scripts, and customized program logic. Such adjustments can improve the processing of unusual materials or complex geometries. The goal is to match the machine’s behavior to the customer’s actual production conditions rather than relying solely on general-purpose parameters.

The company can also conduct technical benchmarking based on customer drawings or physical samples. Engineers may review material characteristics, geometry, thickness, required surface finish, dimensional tolerances, and production volume. Based on this analysis, they can recommend a machine configuration, cutting strategy, wire selection, and parameter set.

Special material optimization is another area of development. Different conductive materials respond differently to electrical discharge energy. Hardened steel, carbide, aluminum alloys, copper alloys, and other materials may require different pulse frequency, pulse width, flushing conditions, and multi-pass strategies. A customized process can improve the balance between cutting speed, wire wear, surface finish, and dimensional accuracy.

11. Comparison with Smaller Wire EDM Machines

Model	Worktable Size	XY Travel	Maximum Cutting Thickness	Maximum Worktable Load
PS35C	550 × 826 mm	350 × 500 mm	280 mm	300 kg
PS45C	650 × 926 mm	450 × 600 mm	280 mm	400 kg
PS50C	740 × 1,060 mm	500 × 700 mm	350 mm	600 kg
PS60C	840 × 1,160 mm	600 × 800 mm	430 mm	800 kg

The PS-C series provides a clear progression in worktable size, travel, cutting thickness, and load capacity. The PS35C is suitable for smaller parts and small-to-medium batch production. The PS45C provides additional working area for medium-sized parts, larger molds, and precision components. The PS50C is intended for large and heavy parts requiring greater capacity. The PS60C is the most suitable option for extra-large workpieces, high-load components, heavy-duty molds, and demanding aerospace or industrial applications.

The advantage of the PS60C over a smaller model is not simply that it has a larger table. Its greater capacity reduces the need for part segmentation, repeated setups, external lifting arrangements, and multiple machine transfers. When a component can be completed in one setup, the manufacturer may achieve better alignment consistency and lower handling risk.

However, a larger machine is not automatically the best machine for every job. A customer should consider workpiece size, production volume, required accuracy, available floor space, lifting equipment, electrical capacity, and the cost of operating a larger system. The PS60C is most valuable when the production requirement genuinely demands its expanded capacity.

12. Applications Across Key Industries

12.1 Aerospace Components

Aerospace manufacturing requires reliable dimensional control, traceable processes, and the ability to machine difficult materials and complex profiles. Wire EDM is useful for components that require narrow slots, intricate contours, and low cutting force. The PS60C’s large working area and high load capacity make it suitable for larger aerospace tooling and structural components.

In aerospace applications, process stability is especially important. A dimensional deviation in a large component can lead to significant rework or rejection costs. The PS60C’s rigid structure, grating-scale feedback, constant wire tension, and multi-pass capability support controlled processing. Final performance should always be validated through application-specific trials and inspection procedures.

12.2 Heavy-Duty Mold Manufacturing

Large molds and dies often use hardened tool steel or other difficult-to-machine materials. Conventional cutting may require high tool forces and substantial tool wear, especially after heat treatment. Wire EDM can produce complex mold profiles with minimal mechanical stress.

The PS60C is well suited to large mold plates, inserts, punches, dies, and cavity components. Its deep cutting capacity is valuable for thick sections, while multi-pass cutting helps refine the finished contour. Taper control can also support mold features that require angled walls or variations between upper and lower profiles.

12.3 Heavy Machinery

Heavy equipment manufacturers often process large plates, mechanical structures, and hardened components. These parts may be too heavy for smaller machines or may require several setups when processed on limited equipment. The PS60C can reduce these limitations through its 800 kg table load and large travel range.

The non-contact cutting process is beneficial for parts where clamping force or cutting force could cause distortion. Operators can use suitable fixtures and supports to stabilize the workpiece while allowing the wire to follow the programmed geometry.

12.4 Precision Mechanical Components

Precision machinery applications may require accurate slots, profiles, gears, punches, dies, and mating components. The PS60C’s controlled four-axis movement and multi-pass cutting process support the production of complex shapes with consistent surface quality.

Its large capacity also allows manufacturers to consolidate related components into a single production setup. This can reduce the number of times parts are moved between machines and improve consistency among components that must fit together.

12.5 Automotive and General Industrial Production

Automotive tooling, stamping dies, fixtures, and specialized production components can benefit from large-format wire EDM. The machine is suitable for both individual high-value parts and batch production when the workpiece size and load justify its capacity.

The cutting efficiency range of 10,000 to 16,000 mm² per hour provides a basis for production estimation. For high-volume work, the manufacturer can evaluate whether automated threading, customized programming, servo drives, and specialized power supply options would improve overall equipment utilization.

13. Operational Efficiency and Total Production Value

Production efficiency should be evaluated beyond the nominal cutting speed. A machine that cuts quickly but requires repeated repositioning, extensive manual threading, or frequent troubleshooting may deliver less practical output than a stable system with a slightly lower nominal rate.

The PS60C can improve practical efficiency through several combined features. Its large table reduces the need for workpiece division. Automatic threading reduces recovery time after wire breakage or job changes. Constant-tension wire control reduces manual adjustment. Automatic tracking water spraying supports stable flushing. LAN and USB interfaces simplify program transfer. Multi-pass cutting reduces the need for secondary grinding and polishing.

Reduced secondary processing can be particularly valuable in mold manufacturing. If the wire-cut surface is uniform and the contour is accurate, manual finishing may be reduced. This can save labor and lower the risk of changing the designed geometry during polishing.

Long-term value also depends on maintenance. Imported bearings, high-precision guides, ball screws, grating scales, and a rigid cast structure are intended to support service life and stable performance. Operators must still maintain guide wheels, filters, working fluid, wire tension, lubrication, electrical connections, and alignment.

14. Installation, Maintenance, and Service Considerations

Before installation, the customer should confirm that the factory floor can support the machine weight and that the route to the installation location can accommodate the machine dimensions. The PS60C weighs approximately 2,700 kg and has listed dimensions of 2,500 × 2,065 × 2,300 mm. Floor loading, lifting equipment, access doors, ventilation, drainage, and electrical supply should all be checked before delivery.

Routine maintenance begins with the working fluid system. The operator should inspect fluid cleanliness, filter condition, pump performance, water pressure, and spray alignment. Paper core filters should be replaced when clogged or when filtration performance declines.

The wire path should be inspected regularly. Guide wheels, wire guides, tension components, and the automatic threading path must remain clean and correctly adjusted. Excessive wear or contamination can affect wire alignment and increase the possibility of wire breakage.

Linear guides and ball screws require appropriate lubrication according to the manufacturer’s maintenance schedule. Lack of lubrication can increase friction and wear, while excessive or unsuitable lubricant can attract debris. Bearing noise, abnormal vibration, backlash, and unusual motor load should be investigated promptly.

Electrical cabinets should be kept clean and dry. Cooling and ventilation should remain unobstructed. Operators should follow safe shutdown procedures and should not modify electrical components without authorization. Qualified personnel should conduct inspections of grounding, power connections, control wiring, and protection devices.

Taizhou Xinchengyang provides technical support intended to help customers establish standardized operating procedures. Technical assistance can include installation guidance, programming support, process parameter recommendations, maintenance advice, and troubleshooting for operating conditions that differ from standard applications.

15. Recommended Selection Process

A customer considering the PS60C should begin by documenting the largest and heaviest workpieces to be processed. Important information includes overall length, width, thickness, weight, material, hardness, required profile, taper angle, surface finish, dimensional tolerance, and expected production volume.

The next step is to determine whether the entire part can be processed in one setup. If not, the customer should identify the causes of the limitation, such as table travel, cutting depth, workpiece weight, clamping space, or wire frame clearance. This information helps engineers determine whether the standard PS60C configuration is sufficient or whether customization is necessary.

Material and quality requirements should also be reviewed. Conductive materials with different thermal and electrical properties may require different pulse settings and cutting strategies. If the component is aerospace-related or used in a high-risk assembly, inspection and traceability requirements should be included in the technical discussion.

For taper cutting, the customer should provide the required angle, cutting height, upper and lower contour dimensions, and the location of the taper relative to the workpiece. The available U/V travel and guide arrangement should then be checked against the actual part geometry.

Finally, the customer should evaluate installation conditions, operator skill, maintenance resources, program workflow, and after-sales support. A large wire EDM machine produces its best value when the surrounding production system is prepared to use its capacity effectively.

Its advantages come from the combined design of the machine rather than from one specification alone. The rigid HT250 T-shaped bed supports stability. Resin sand castings and aging treatment help preserve structural precision. Linear guides, ball screws, grating scales, imported bearings, and servo options support controlled motion. The adaptive constant-tension system and double-sided tightening mechanism stabilize the electrode wire. Automatic threading, adjustable gemstone guides, automatic water spraying, and multi-pass cutting improve operating convenience and process consistency.

The company’s manufacturing strengths include long-term EDM experience, in-house product development, mechanical and electrical integration, accuracy testing, customization, and technical support. Its ability to work from customer drawings or samples allows the PS60C to be adapted for special workpieces, materials, cutting depths, and production processes.

For aerospace, heavy-duty mold manufacturing, large mechanical components, precision tooling, automotive dies, and other demanding industries, the PS60C offers a practical combination of capacity, precision, adaptability, and production stability. Proper application analysis, installation, programming, maintenance, and acceptance testing remain essential, but the machine provides a strong foundation for manufacturers seeking reliable large-format wire EDM performance.
