1. It is caused by unreasonable processing parameters of CNC

If you can see if you can change the processing parameters of the high-speed drilling and tapping machine, it may be that the setting of the parameters is unreasonable.

2, may be the process selection error

On the other hand, an effective way to avoid scratches is to use a boring hole instead of a hole, and the process selection is incorrect.

3, to refer to CNC processing drawings

The first thing you need to see is the machining diagram. If the thickness of the workpiece machined by the CNC machining center is not very thick, you can use a reamer to twist it.

4, there may be problems with chip removal

It is also possible that your coolant has a slow water output and insufficient water, and the chips cannot be discharged.

5, is caused by too high drilling speed

Cnc machining bit angle is well grounded, and the drilling speed is too high

Lemo has over 40 CNC machining centers, include 3 axis,4 axis , 5 axis.
