Features and precision of grinding tool grinding
Grinding is a part of the surface of the finishing, precision machining, which has the following characteristics.
1 high precision grinding research Tang adopts a very threading powder, rub a layer of thin metal at low speed and low pressure. The heat produced in the grinding process is very small, the deformation of the workpiece is very small, the surface modification layer is very slight, so it can obtain high precision.
Surface. The size accuracy can be reached 0.01Um.
2 the surface shape precision high abrasive cutting quantity is very small, the movement is complex, moreover is not affected by the movement precision, therefore may obtain the high shape precision. Ball roundness can reach. Yang, cylinder cylinder can reach O. t IV e another aspect, due to the abrasive cutting a very small amount, original position error can not get all correct, so grinding can't improve position accuracy of parts.
3. The surface rough degree value small parts and research some relative motion between, every trajectory not with a soft motion trace repetition, therefore it can uniformly resection parts on the surface of the convex peak and reduce the surface roughness. Grinding surface roughness
Up to Rd.01M.
4. To improve parts of the surface resistance of perceptual grinding surface roughness Lai is small, the friction surface duo coefficient decreases. Effective contact area increase wear resistance is improved.
5 to improve the surface of the parts surface pox fatigue strength of the existence of compressive stress, which is conducive to improving the fatigue strength of the parts surface.
6 the process is simple and easy to manufacture. It is not only suitable for single piece production, but also is suitable for mass production, and can be processed with steel parts, cast iron, all kinds of nonferrous metals and non gold chips. For example, glass ceramics, diamond research and other hard brittle materials.
7. Application of a wide range of grinding is widely used in modern industrial production in all kinds of precision parts processing, measuring gauge, optical glass, precision tools, semiconductor components, precision fit surface need after grinding processing.
