What is a dozen cup machine processing surface quality?

The destruction of the cup machine parts, usually start from the surface layer. Work product reliability and life expectancy, depends largely on the surface quality of the main parts. So, to master all kinds of mechanical processing, and the effect of technical factors on the machining surface quality, and use these rules control process, finally to improve the surface quality, improve the product with the purpose of the performance. Mechanical processing surface quality is refers to the parts in glass table after machining and surface micro geometry shape error and the physical, chemical and mechanical properties. The workpiece in machining due to the effect of cutting force, cutting heat, the surface and matrix material performance is different, the larger changes in physical and mechanical performance. If, in the process of cutting or grinding machining surface resulted from the plastic deformation of shear sliding between crystal, the lattice distortion, and produce grain stretched, broken and fibrosis, cause the phenomenon of strength and hardness of the surface layer increase, called for the cold work hardening phenomenon. Hole is all sorts of lid machine parts appear on one of the most geometric surface. According to the hole in the connection of the relation between parts and parts, can be divided into the hole and hole. The mating hole drilling, expanding out directly on the blank commonly; Together with the hole must be in drilling, reaming, etc, on the basis of rough machining, according to the requirements of different accuracy and performance quality, as well as parts of the specific circumstances, such as material, size, structure for further processing.
