The influence of the specifications and surface roughness of the high quality grinding disc
in 4 inches China grinding disc factory
on the workpiece.
The specification of the high quality grinding disc determines the influence of the surface roughness of the grinding disc on the performance of the part: the smaller the surface roughness value of the grinding disc, the better the wear resistance, corrosion resistance and fatigue resistance of the part. The larger the surface roughness value of the grinding disc specification, the opposite is true.
In the grinding process, it is necessary to pay attention to the high quality grinding disc specifications to reduce the surface roughness. The main process factors affecting the surface roughness of the grinding process have a significant influence on the grain size of the grinding disc. The finer the grain size of the high quality grinding disc, the more abrasive grains involved in the grinding, the lower the surface roughness of the grinding. Grinding disc specifications in the processing of general grinding, take the 46-80 size grinding disc, fine grinding should use 150-240 size grinding disc, mirror grinding should use W10-W7 particle size resin graphite grinding disc, can A good surface roughness of the workpiece is obtained.
In recent years, with the development and application of new technologies and the development of high-precision grinding technology, the specifications of high quality grinding discs are becoming more and more abundant, the grinding size is 0.1-0.3μm, the surface roughness is 0.2-0.05μm, and the surface deterioration layer and residue are ground. The stress is very small and the processing quality is significantly improved. Form grinding, especially high-precision forming grinding, is often a key issue in life.
There are two problems in forming grinding:
1. Grinding disc quality: Mainly the grinding disc must have good self-tanning and shape-retaining at the same time, and the two are often contradictory.
2. The high quality grinding disc dressing technology: that is, efficient and economical to obtain the required disc profile and sharpness. Therefore, in order to improve the efficiency and precision of grinding, especially for the efficient finishing of difficult-to-machine materials, CBN grinding discs are used for efficient and powerful grinding, which makes the powerful grinding break the limitation of traditional grinding, and the productivity is doubled. It does not need to be roughed and can be directly ground into finished products, which not only improves the processing efficiency but also improves the processing quality. In the grinding process, the correct choice of the high quality grinding disc plays a decisive role in the efficiency of the machining.
