About The Power Drawbar
The Power Drawbar integrates with your PCNCÂ Mill for lightning-fast manual tool changes with the push of a button and eliminates the need to hand-tighten your drawbar. To change tools, a pneumatic multi-stack air-over-air cylinder is actuated to depress the drawbar, releasing clamping pressure and opening the collet without putting harmful load on the spindle bearings. When the cylinder is released, the drawbar tightens and the tool is held firmly in place. This system provides over 2500lbs of holding force to the tool.
The power drawbar is designed for use with the Tormach Tooling SystemÂ® (TTS), but easily pivots away to allow manual tightening of the drawbar if necessary for conventional R8 tooling. It integrates with the Tormach ATC as well as an optional foot pedal (both sold separately).
The Power Drawbar kit includes pneumatic cylinder assembly stack, drawbar, electronic control circuitry, push-button pendant, and all necessary pneumatic tubing and electronic wiring. Requires 90 psi air supply (not included).
