From the perspective of the development and sales situation of the automated parts machining industry, manufacturing entrepreneurs are changing in this direction. In the process of precision parts machining, the physical raw material can deform the metal material due to the rounded corners and extrusion of the cutting edge during the workpiece cutting process, which will cause serious deterioration of surface roughness and the appearance performance of accumulated burrs will also be completely irregular, Therefore, it is easy to cause knife marks on the surface of the workpiece with different depths, widths, and widths. For example, there is a mismatch between the rotational speed and cutting speed, the material is too hard and the cutting amount is too much, the workpiece is not tightly compressed, and the elasticity of the workpiece is too large. For example, for rubber products, the tool body is too long, the tool holder shakes during processing, and the machine tool itself, such as the screw and track, has too large a clearance. All of these will inevitably increase the roughness of the surface of the parts. How to carry out surface treatment in precision parts processing? In general, the surface morphology, phase composition, microstructure, defect state, and stress state of materials are changed through physical, chemical, and other methods. The chemical composition of the hardware model on the surface of the material remains unchanged.
Surface hardening refers to a heat treatment method that uses rapid heating to austenitize the surface without changing the chemical composition and core structure of the steel, followed by rapid cooling, to achieve surface hardening. Sandblasting treatment is a process method that uses high-speed sprayed sand or iron particles to impact the surface of the workpiece, in order to improve some of the mechanical properties of the part and change the surface state. Sandblasting and shot peening have similar processes, with the main difference being in the diameter of the sand particles. This process is mainly used to improve the mechanical strength, wear resistance, fatigue resistance, and corrosion resistance of parts. It can also be used for surface extinction, removal of oxide skin, and elimination of residual stress in castings, forgings, and welded parts. Knurling is a process in which a hard roller or roller is applied to the surface of a rotating workpiece at room temperature and moves along the direction of the generatrix. Non standard automated part processing in Kunshan City causes plastic deformation and hardening of the workpiece surface to obtain an accurate, smooth, and reinforced surface, or a specific pattern processing technique.
The technical processing method of metal wire drawing is to force the metal through the mold under external forces, compress the cross-sectional area of the metal, and obtain the required cross-sectional area shape and size. The tool that changes its shape and size is called a drawing die. Drawing can be made into several types according to decorative needs, including straight lines, irregular lines, ripples, threads, etc. Precision machining is the process of continuously reducing and leveling the original errors on the machined surface. The principle of leveling is to compare and inspect closely related workpieces or tool surfaces, identify their differences, and then perform mutual correction or benchmark machining. This requires advanced manufacturing equipment and processing technicians, as long as they possess these two points, precision parts processing will be successful.
