1：Scratches or burrs on the material surface during processing

This may be caused by tool wear, excessive feed speed, or loose fixture. It is recommended to check the tool status, adjust the cutting parameters (such as reducing the feed speed), and ensure that the workpiece is fixed firmly.

2：Severe tool sticking during stainless steel processing

Stainless steel is prone to work hardening, so special tools (such as cobalt-containing high-speed steel or coated tools) need to be selected, the coolant flow rate should be increased, and the cutting speed should not be too high.
