The application of high-frequency vibrations to conventional cutting tools causes intermittent contact between the workpiece and the tool, resulting in a fundamental change in the conventional cutting mode. The problems inherent in the traditional cutting process are solved, such as vibration during cutting and thermal deformation of the cutting, so that excellent cutting results are obtained. This product rotary knife machine is more convenient to operate, higher stability, faster cutting speed, better effect, no need to worry about material displacement, saving time and effort, suitable for medium and large processing plants.
