Precision machining in terms of cutting tool, mainly used in the process of operating the diamond sand wheel, to a certain extent, effective control turning back and feed, in ultra-precision grinding machine, the runtime can be ductile grinding way, namely the nano grinding. Even the surface of the glass optical lens can be obtained. Precision machining and ultra-precision machining of development trend from long term point of view, the development of its equipment manufacturing technology is the current world development of the main strategy of the national economy and the direction of the decision, is one of the important means of a national economic development, is also a national independence, prosperity and economic steady development, science and technology leading long-term strategy. The development of science and technology of precision precision machining and ultra-precision precision machining technology is also put forward higher requirements. Precision precision machining of high efficiency and high precision processing and ultra-precision processing to a certain extent, can obtain high surface quality and surface integrity, but can be sacrificed in order to ensure the efficiency. Using the method of drawing process, the maximum deformation force is only 17 t, and using the method of cold extrusion process, the deforming force 132 t, the effect on the cold extrusion punches the unit pressure of more than 2300 mpa. Die except needs to have high strength, still need to have sufficient impact toughness and wear resistance. Precision machining of metal blank strong plastic deformation in the mould, so it will make the mould temperature rise to about 250 ℃ ~ 300 ℃, thus, the mould material needs certain tempering stability. Due to the above situation, the service life of cold extrusion die is far lower than the stamping die. Precision machining in pursuit of high reliability, the runtime for bearing load again while doing relative motion of the parts, can effectively reduce the surface roughness at run time, so that it can improve the wear resistance of the parts, increase its work stability, prolong the service life. Si3N4 used in high speed high precision bearing. The surface roughness of the ceramic ball is asking for several nanometers. Processing and chemistry of the metamorphic layer and lively, susceptibility to corrosion, so from the perspective of improve the ability of corrosion resistant parts, the processing of metamorphic layer as far as possible.
Finding a reliable solution for the machining parts cnc aluminum not only supports operation of the entire system but also enhance the beauty of your workplace.
