The PSC (Polygon Shank Coupling) system is a modern quick-change tooling interface designed for CNC turning, milling, and multitasking machines. Its polygonal taper geometry, combined with a short, rigid design, ensures maximum torque transmission and exceptional stability. The primary function of the PSC polygon shank is to provide fast tool changes, high-precision positioning, and strong clamping force, allowing machine operators to reduce setup time while maintaining accuracy and repeatability. It is used in roughing, finishing, drilling, boring, and milling applications, enabling manufacturers to achieve faster cycle times, flexible production, and superior machining quality. By minimizing downtime and ensuring rigid tool clamping, the PSC polygon shank enhances productivity across both high-volume production and precision machining environments.
High Rigidity: The polygonal taper design offers large contact surfaces, ensuring excellent torque transmission and resistance to bending forces.
Quick-Change Capability: Tool changes can be performed rapidly without sacrificing repeatability, improving overall production efficiency.
Superior Accuracy: Achieves positioning accuracy of ≤0.003 mm, maintaining precise machining even in demanding applications.
Wide Compatibility: Available in multiple sizes (PSC32, PSC40, PSC50, PSC63, PSC80, etc.), allowing flexibility across machines and tooling systems.
Versatility: Supports turning, milling, drilling, boring, and even heavy-duty cutting, making it suitable for multitasking machines.
Durability: Manufactured from high-grade alloy steel with surface treatments for wear resistance and long service life.
These features make the PSC polygon shank a reliable solution for manufacturers requiring both precision and productivity in modern machining operations.
Runout Accuracy: ≤0.003 mm for high-precision cutting.
Torque Transmission: Capable of withstanding high torque loads, ideal for heavy-duty machining.
Clamping Method: Mechanical clamping with polygonal taper interface for maximum rigidity.
Shank Lengths: Multiple length options to suit different machine and application requirements.
Max RPM: Suitable for high-speed machining applications up to 15,000 RPM depending on size.
These specifications ensure that PSC polygon shanks can be applied in both high-speed finishing and heavy-duty roughing operations, providing unmatched flexibility in modern CNC manufacturing.
Installation: Ensure that the shank and machine spindle interface are clean and free from dust, chips, or oil before installation.
Clamping: Use the recommended clamping system torque to secure the polygon shank in place. Over-tightening may cause damage, while under-tightening may reduce rigidity.
Tool Changes: Take advantage of the quick-change capability to minimize downtime, but always verify alignment and cleanliness to maintain precision.
Cutting Parameters: Match feed rates and spindle speeds with the appropriate PSC size to prevent excessive wear or vibration.
Maintenance: Regularly inspect the polygon surfaces and clamping mechanism for wear, corrosion, or damage. Apply light lubrication if recommended by the manufacturer.
Following these best practices ensures that the PSC polygon shank delivers consistent accuracy, strong clamping, and maximum productivity over extended usage cycles.
Aerospace: For structural components, turbine parts, and engine housings requiring rigid clamping and high precision.
Automotive: For engine blocks, transmission housings, and other high-volume parts where quick tool changes reduce downtime.
