Enable single-setup, end-to-end turning and grinding of shaft workpieces with industrial-grade Face Drivers (mechanical and hydraulic face driving systems). Engineered to mount into CNC lathe spindle tapers or chucks, these heavy-duty workholders utilize a spring-loaded center pin surrounded by hardened drive pins. As tailstock pressure forces the workpiece face onto the driving pins, the pins bite into the material face to transmit maximum turning torque without jaw interference. This allows complete outer diameter machining, threading, and profiling along the entire length of the workpiece in a single clamping operation.
