You can solve your problem by raising the center height of the swing shaft, or reducing the pressure of the oilstone and reducing the swing range. Adjust the range. Try it yourself. The several plans I mentioned above are just a general adjustment direction. You need to know the specific settings of the workpiece speed, swing frequency and fine-rough overtime.
