For difficult-to-machine insert materials, different cutting methods have very different damage to the cutting fluid. No matter which cutting method is selected, the principle is the same, that is, the cutting force and cutting area temperature are reduced as much as possible.
The cycloid cutting method of 920 single hydraulic paper cutter can reduce the cutting area and the actual cutting angle of the cutting fluid, thereby prolonging the heat dissipation time of each tooth and reducing the cutting temperature; the spiral interpolation method can make the cutting amount of each tooth Relatively uniform, to avoid cutting forces concentrated on a few teeth, accelerate wear, especially in the corners. The large feed method is used to effectively reduce the cutting force under the condition of small cutting depth and large feed amount, so that the cutting heat in the cutting area is minimized and the temperature is the lowest.
