PSC POLYGONAL TOOLING SYSTEM – INCREASED STABILITY & VERSATILITY

Take your machining up to the next level to improve efficiency and quality in the manufacturing process with the PSC polygonal tooling system – offering increased stability and versatility in machining.

Per ISO 26623, the PSC polygonal interface features a unique tapered polygon that is a main element in torque transmitting, centering, and clamping. With double contact on both face and taper, as well as great cross-sectional strength, this interface is unrivaled in terms of high clamping force and bending stiffness.

The combination of these excellent properties gives the PSC polygonal interface a clear advantage over HSK and 7/24 tapers with approximately 2x better bending and torsional characteristics. This translates into greater process stability, higher productivity, and lower costs.

PSC POLYGONAL – KEY BENEFITS

Key benefits of using PSC polygonal turning tools include:

  • Reduced setup and tool change time – maximum utilization of the machine
  • Increased stability and versatility – in vertical lathes, multi-tasking machining centers and machining centers with turning possibilities
  • Ultimate repeatability – allowing online tool presetting
  • Reduced tool inventory and storage space in workshop – due to universal interface for both turning and milling
  • Self-centering system provides high precision and repeatability
  • Quick change, monobloc system without additional interfaces

PSC POLYGONAL TURNING TOOLHOLDERS – SOLUTION FOR MAXIMIZING PROCESS EFFICIENCY

Additionally, direct high pressure coolant nozzles increase tool life with higher feeds and speeds.

More time making chips and less time in unwanted stops makes an investment in PSC Polygonal taper toolholders an ideal choice with fast ROI.

Key attributes of PSC polygonal toolholders include:

  • Extremely stable and rigid connection between tool and the machine
  • High torque and bending forces transmission due to simultaneous tapered polygon and face contact with machine spindle
  • Self-centering ability due to unique design
  • Internal coolant supply, directly to the tool tip
  • Best solution for all processes – both in turning and milling
  • Modular design for flexible tooling
  • Standardized interface as per ISO 26623
  • 6 sizes, flange diameters 32-40-50-63-80-100 mm (sizes C3-C4-C5-C6-C8-C10)

DRIVEN & STATIC TOOLS BEST PAIRED WITH SHORT PSC POLYGONAL TOOLHOLDERS

Quick-change PSC polygonal adapters have exactly the same ISO 26223-1 taper as normal PSC polygonal adapters key with one difference – the absence of the gripper groove for automatic tool change (ATC). As a result, tool length is reduced which helps achieve a stable process and therefore higher quality parts and more efficient machining.

Key benefits of short adapters include:

  • Allows for larger cutting tool envelope
  • Greater cutting stability
  • Extends tool life and accuracy due to reduced tool projection
  • Increases surface finish
  • Decreases load on driven toolholder bearings
  • Reduces setup and tool change time
