Clamping apparatus with device for measuring the distance between a chuck and a worktool or workpiece holder

摘要

The arrangement has a chuck (2) and a workpiece or tool holder that fits the chuck, whereby the chuck has posts (7) with contact surfaces for aligning the tool or workpiece in an X and Y direction and end faces for fixing a plane perpendicular to the Z-direction. Devices are formed in the contact surfaces and in the end faces for measuring the distance between the chuck and toll or workpiece holder. An independent claim is also included for a method of machine processing of workpieces using an inventive arrangement.
