Option QC: Quick change jaw system

The QC system accurately locates top jaws previously machined on the chuck to maintain accuracy within 5 µm TIR.  This high accuracy is achieved without re-machining the top jaws after changeover, thereby eliminating the most time consuming process associated with jaw change on precision chucks.  This feature significantly reduces machine set up time, and will improve a machine's flexibility in a JIT environment. QC top jaws can also be machined off-line on a jaw turning fixture, or another QC chuck.  In this case chucking accuracy is maintained within 0.01 mm TIR when top jaws are transferred to another chuck.

A further advantage of the QC-System is it's rigidity. The QC-System is predestinated to withstand high clamping forces. On this option the base jaws (1) are ploting with locating pins (2) the top jaws (4) into conical location bores (3) with exreme high accuracy.
