Collet chuck module for cylindrical parts

SCHUNK, the competence leader for clamping technology and gripping systems, extends its modular system for efficient workpiece clamping with a particularly smart collet chuck module for parts with cylindrical shanks. Lengths of pipes, shafts, and other small parts can be precisely clamped with the SCHUNK VERO-S SEZ within a very short time, and can be machined from five sides with an optimal accessibility. The same applies for unstable workpieces with a short shank. Since the system can be quickly made ready for use, it is particularly suitable for machining individual pieces, small series such as plungers and ejectors in tool and mold making.

First of all, the comparably light but robust collet chuck module is put onto an existing SCHUNK VERO-S quick-change module, is equipped with a workpiece, and then the pull-down jaw system is activated. This ensures a maximum clamping precision, great dimensional stability, and an adjustable depth stop provides for a great repeat accuracy.

Coolant is discharged through an integrated drain. Since the system can be used together with all common ER collet chucks, it provides a maximum degree of flexibility to the users. The SCHUNK VERO-S SEZ collet chuck modules are available for SCHUNK VERO-S NSE plus 138-V1 (ER 32-120 and ER 40-120), and VERO-S NSE mini 90-V1 (ER 25-100) quick-change pallet modules. The clamping diameter amounts from 2 to 20 mm (ER 32-120), 3 to 26 mm (ER 40-120), or 1 to 16 mm (ER 25-100). The maximum clamping depths is 96 mm (VERO-S SEZ), or 85 mm (VERO-S SEZ mini).
