Mandrels - Collet chucks

Mandrels and collet chucks are used for clamping most rotationally-symmetric workpieces for cutting or grinding machining on machine tools or machining centers. Furthermore, they are used on measuring machines for high-precision clamping. Due to their rather small clamping range, they are used for mainly similar geometries. They can be clamped quickly and above all with a high level of (repeat) accuracy.

Cartridge mandrels, hand-operated

for manual, precision, internal clamping for turning, milling, grinding and gear cutting

Cartridge mandrels, force-actuated

for automatic, precision, internal clamping for turning, milling, grinding and gear cutting

Cartridge mandrels, classic

for manual internal clamping without end-face stop for measuring operations and easy grinding

Segment clamping mandrels

for force-actuated, precision, internal clamping for turning, milling, grinding and gear cutting with a quick-change system and long sleeve elongation

Collet chucks

modular system for precision external clamping for turning, milling and drilling as well as measuring

Collet chucks, high-precision

for high-precision, external clamping or workpieces with smooth or toothed outer geometry for turning, milling, grinding and measuring operations

Collet chucks for DIN collets

for external clamping with DIN collets or segment collets for turning, milling and drilling as well as measuring

Selected, individual solutions for special clamps with mandrels and chucks

KFR cartridge mandrels

for turning different pressed parts with concentricity of 0.01 mm. Can be easily reconfigured by changing the clamping sleeve and/or stop
Fixed stop with damping ring, air sensing and ejector

MFR cartridge mandrels

for stationary milling/drilling
Concentricity of 0.015 mm. Easy actuation by light roller bearing

Absis segment clamping mandrels

for gear cutting / turning with stable clamping and a lot of tool freedom. Centering by the segment sleeve, clamping by the pendulum bell. With quick-change system on the basic take-up.

KFG sliding clamping mandrel Ø 30 mm

for turning a differential housing. Two clamping planes, compensation of diameter differences. Pneumatic control of the workpiece stop, air sealed.

KFG sliding clamping mandrel Ø 90-113 mm

for turning of clamping cylinder liners. Left clamping plane force-actuated by draw bar, right plane spring-actuated to compensate for workpiece tolerances. Stop can be pulled back. Different workpiece diameters can be clamped by changing the top jaws.
