Chuck, Mandrel Clamp Gears’ Pitch, Inner Diameters

Röhm Products of America’s KZF-S external clamping gear chuck is specifically made for gear surface face grinding. It is well-suited for clamping gears and other workpieces that have an external plane or gear tooth geometries accessible from the outside. Additionally, the chuck enables turning or grinding of faces and internal diameters that are concentric to outer gear pitch diameters. The company says the chuck maintains its centrifugal force for smooth rotation of less than 0.01 mm.

The Agilis segment clamping mandrel is said to be an ideal partner to the KZF-S. It holds parts on their inside diameters, and the gear chuck holds them on their pitch diameters. It is built for automatic changeover and small-diameter clamping. The system draws in workpieces against a rigid workstop, which happens independently due to the incorporated pull-back action of the quick-change taper sleeves. The power-operated segment clamping mandrel offers concentricity tolerances within 0.01 mm as well as repeatable high clamping accuracy.
