Polygon Shank ■ General Features Polygon shanks feature keyless couplings with a characteristic polygon shape, which bear cutting torque evenly on three surfaces to provide high rigidity and high index accuracy. For support with non-standard design specifications, contact us directly. ■ Characteristics ■ Coupling Structure ● Sizes Two faces contact with ・Supports polygon shank size PSC32(DCSFMS=32mm) to the taper + end face PSC80(DCSFMS=80mm) ● High rigidity, High precision ・High rigidity from two faces contact with the 1/20 G tapered polygon shape and end face. ・Cutting torque is equally distributed to three faces with keyless Tooling coupling, and variations in cutting edge height are also reduced. ・Repeat accuracy when changing tools is ±2μm for all three axes. ● Faster tool replacement ・Tool replacement time can be greatly reduced because inserts do not need to be replaced while in the machine. Improved centering ● Supports internal coolant ■ Custom Examples For support with non-standard design specifications, contact us.
