1, the machine itself is shaking.

2. The tool selection is incorrect. If you want to cut PVC without burrs, you can use double-edged spiral knives and single-edged spiral knives, and finally import materials.

3, tool wear, the blade has a gap.

4. If there is no problem in the future, improve the tool programming path:

The operation method is as follows: when programming, leave a margin of 0.05 mm for side cutting, and finally polish the knife again.

Please contact me if you don't understand. The code word is not suitable, I hope it will be adopted.
