◆FAQ

Is there some suggestions for using workholding chuck? 

Best Practices for Using Workholding Chucks
1) Proper Setup: Carefully set the workpiece in the chuck and ensure that the jaws are evenly gripping it. This minimizes runout and improves machining accuracy.
2) Torque Specifications: Follow the manufacturer’s recommended torque settings when tightening the chuck to prevent slippage or damage to the workpiece.
3) Regular Maintenance: Inspect and clean chucks regularly to check for wear, damage, and debris that can affect gripping performance.
4) Use Soft Jaws: On three- or four-jaw chucks, using custom soft jaws can protect finished surfaces and improve gripping on irregular shapes.
