The accuracy of cutting machine is a very important attribute. If the deviation of accuracy is very likely, it will lead to waste of material. Of course, long-term wear will lead to the decline of mechanical accuracy. So how to improve the accuracy of the cutting machine? Now let's have a brief understanding of it.
The machining precision is high and the surface roughness is low. When grinding, the abrasive blade n1P is often sharp, the radius of the edge P is very small, and the cutting edge is very much, so it can cut a thin layer of metal. Cutting thickness can be as small as a few microns, and minimal residual area height.
The grinding machine has high accuracy, rigidity and stability, and has a micro feed mechanism that controls the depth of small cutting. It can carry out micro cutting and achieve precision machining.
Dense cutting, the cutting speed is very high, such as the common external grinding p*30 35m/s, high speed grinding? >50m/s* when numerous cutting edge at high speed from the surface of the workpiece and cutting out, each cutting machine cutting edge is removed from the workpiece in very small amounts of metal, residual area height is very small, which is favorable for the formation of low surface roughness degree.
