The jaws are designed for mounting on turning-and-boring lathe 1525, 1532 and other machines with a T-slot face (center-to-center distance of T-slots – 200 mm) and fixation by a stop bar that moves the jaw along the faceplate and fixes it against lengthwise movement with the stop in the slot 35H9 and the slot of the faceplate.
Simultaneously using the movement of several tools, one can perform multi-tool machining. It greatly improves productivity and makes performance easier.
This design allows high accuracy machining of large workpieces.
Jaws can be hardened or non-hardened (soft). Hardened jaws are used for clamping workpieces with untreated surfaces. Non-hardened jaws provide high accuracy of installation, since the jaws themselves are directly machined on the lathe before machining a batch of parts, and a workpiece has previously treated surfaces.
