Collet chucks

Modular system for precision external clamping for turning, milling, drilling and measuring

The new and modular CAPTIS clamping system is convincing in both rotary applications in turning machines as well as in stationary use in drilling, milling and machining centers and also measuring machines. The encompassing clamping enables precise concentricity and repeatability of 0.005 mm without deforming the workpiece.

The conversion from outer to inner clamping can be done in less than 1 minute with the quick-change function.  It works so well that we have registered this function for a patent. It works with any collets from the Captis series. Simply insert the Absis-C internal mandrel in the Caps gripper. Finished!
