The main reason for the machining process, from our hardware precision process, in fact, there are also a lot of reasons will have a certain impact on the surface roughness of its parts. Mainly there are tools and workpiece materials, CNC conditions caused by the reasons. About the geometric reasons it is mainly affected by the shape of the tool, the angle of deviation and vice angle of deviation will have a greater impact on the surface roughness.
We then process plastic materials will also form band cutting and the formation of cumulative cutting tumor, and hardness is also very high, for physical reasons in the workpiece cutting process, the cutting edge rounding and extrusion can make the metal material deformation, which will cause serious deterioration of the surface roughness, cumulative cutting tumor appearance properties will also be completely irregular, and thus it is easy to make the workpiece surface appear depth and width of different knife marks. There are also such as speed and cutting speed mismatch, the material is too hard to eat too much tool, the workpiece is not pressed, and the workpiece is too elastic, rubber products such as tool body is too long, processing tool shake, the machine itself, such as: screw line rail and other activities such as clearance is too large, etc.. These are bound to increase the surface of the parts produced roughness.
The advantages of cnc machining center of in industrial production, involving materials, technology, cost, the use of the number of issues, there are many parts can not be mass production through the machine, so that it is necessary to carry out small-scale or small medical parts processing through some special process, the middle may also involve manual processing links. Generally, the main use of CNC, rapid mold, vacuum silicone re-mold process to achieve small batch production. cnc processing of the advantages of medical parts processing from single to triple digits, is through the simple mold, soft mold, or direct processing out. Medical parts processing is generally turning, milling, planing, grinding, pincer and other usual mechanical processing, pincer undercutting, drawing lines, punching, tapping, etc.. Representative industries are aviation, aerospace industry, shipbuilding industry, construction machinery industry, machine tool industry, etc. The typical representative of mass production is the automobile industry, while the trial production of new models and engines etc. in the automobile industry and the mold industry which mainly serves for mass production still belong to single small batch production.
