DIY Pnuematic Drawbar for Bridgeport Type Milling Machine · 模型 26352
This assembly makes changing tools on a Bridgeport type milling machine much much faster! No more wrenches and hammers to knock the collets out of the taper, the impact of the pneumatic impact loosens and knocks out the collets in one go. This even works on my M-head which does not have a spindle brake. Inspired by the NYC CNC project: https://www.youtube.com/watch?v=z8CKZCZWwOI Impact Wrench 3D model from: https://grabcad.com/library/impact-wrench-4 Other parts you'll need: 8mm linear shafting LM8UU linear bearings The pneumatic impact: https://www.harborfreight.com/3-8-eighth-inch-drive-75-ft-lbs-torque-compact-air-impact-wrench-93100.html Some compression springs (such as https://www.homedepot.com/p/Everbilt-11-16-in-x-1-1-4-in-and-7-8-in-x-4-in-Zinc-Plated-Compression-Spring-4-Pack-16084/202045472) Spacers for the springs (will depend on your specific drawbar setup)
