1. Epiproducts such as chips are easy to bond on the cutting edge, which will affect the processing effect and service life of the tool, and should be cleaned up in time.
2. When machining copper alloys, the cutting speed increases, the cutting force will decrease, and the coefficient of deformation will also decrease.
3. The expansion coefficient of pure copper is large, which is easy to cause deformation under the influence of cutting temperature, and it is not easy to control the processing size and geometric accuracy.
4. When the workpiece is processed, the surface is prone to water ripple and noise.
