Large cutting power, also, the energy consuming is much. The grinding wheel is composed of a lot of abrasive CNC lathes, the distribution of abrasive grains in the grinding wheel is chaotic, cutting mostly at negative rake angle, and the tip has a certain circle Arc radius, and thus cutting power is large, machine energy consuming is much.

High flexibility. Replacement of the application software can easily be replaced within a certain range from the processing of one part to the processing of another part, which significantly reduces the equipment adjustment and production preparation time.

High precision machining tolerance and very low surface roughness. Each abrasive grain cutting off the chip layer is very thin, usually has several microns, so the appearance can get high precision and low surface roughness.

Wide processing range. Grinding wheel abrasive has high hardness, thermal stability, not only can be processed non-hardened steel, cast iron and non-ferrous metals and other materials, but also can processing hardened steel, all kinds of cutting tools and hard machine tools such as high hardness materials. Complete the machine operation and the process of automation.
