Jaw change in seconds with SCHUNK PRONTO

Jaw change in seconds with SCHUNK PRONTO

Added to MTDCNC by MTDCNC on 11 January 2014

With a change-over time of 5 seconds per jaw, the SCHUNK PRONTO quick jaw change sys-tem offers turbo-charged set-up times for all standard lathe chucks with fine serrations of 1/16’’ x 90° and 1.5 mm x 60°. The quick-change retrofit set from the competence leader for clamping technology and gripping systems consists of supporting and changing jaws. It is suitable for O.D. clamping of pre-machined and finished parts. Via the ion of the interchangeable insert, the clamping range can be extended by up to 16 mm, without hav-ing to re-set the supporting jaw, an increase of 300% in comparison to conventional lathe chucks.

Form-fit clamping for high force and torque transmission

For jaw changes with exact repeat accuracy, the locking is released with an Allen key, the jaw is removed and replaced by another. This eliminates incorrect positioning. In locked condition, a six-sided form-fit clamping ensures maximum process stability, and provides high force and torque transmission. As required by the application, three supporting jaw variants are available for small, medium, and large clamping ranges. As top jaws, the inno-vative family-owned company provides four hard claw inserts for various diameters and clamping ranges as well soft interchangeable inserts for finished parts processing. Once they have been turned, the inserts can be used again and again on a system. The clamping depth can be varied using a workpiece stop. Initially we will be offering the low-maintenance quick jaw change system for lathe chucks with size 250. Further sizes are al-ready planned.
