Polygonal shanks feature keyless couplings with a characteristics polygonal shape, which bear cutting torque every on three surfaces to provide high rigidly and high index accuracy.

• Size

Corresponding to Polygon Shank size from PSC32 (DCSFMS=32mm) to PSC80 (DCSFMS=80mm).

• High Rigidity and High Accuracy

Two surface restriction by 1/2 polygon taper and the end face offer High rigidity.

Keyless capling offers bearing cutting torque on three surfaces and High index accuracy in the edge position.

High precision and a repeatbility of ±2μm in 3 axes are realized.

• Shorten the tool exchange time

While It’s possible to gain higher machine utilization time.

• Coolant supply

(Lower than 1MPa)
