The Importance Of Cutting Piece Selection In Grinding
Grinding is generally used as the final step in the machining of workpieces. The task is to ensure that the parts of the product meet the precision and surface quality required on the drawings. Grinding surface roughness is closely related to part accuracy, and certain precision should have corresponding surface roughness. Under normal circumstances, the size should be effectively controlled, the roughness Ra should not exceed one-eighth of the dimensional tolerance. The effect of grinding surface roughness on the performance of the part is: the smaller the surface roughness value, the part The better the wear resistance, corrosion resistance and fatigue resistance.
The opposite is true.
Therefore, in the grinding process, care must be taken to reduce the surface roughness. The main process factors affecting the surface roughness of the grinding process have a significant influence on the particle size of the [url=https://www.auroraabrasive.com/14-inches-cutting-disc/]cutting disc for stainless steel[/url]. The finer the particle size of the [url=https://www.auroraabrasive.com/5-inch-resin-metal-cutting-disc/]5 inch resin cutting disc for metal[/url], the more abrasive grains involved in the grinding, the lower the surface roughness of the grinding. Generally, the cutting piece of grain size of 46-80 is used for grinding, and the cutting piece of grain size of 150-240 is used for fine grinding. The resin graphite cutting piece of W10~W7 grain size should be selected for mirror grinding, and a good workpiece can be obtained. Surface roughness.
In recent years, with the development and application of new technologies, the development of high-precision grinding technology has made the grinding size 0.1-0.3μm, the surface roughness is 0.2-0.05μm, the grinding surface metamorphic layer and residual stress are very small, obviously Improved processing quality.
Form grinding, especially high-precision forming grinding, is often a key issue in life. Form grinding has two problems:
First, the quality of the cutting piece, mainly because the cutting piece must have good self-tanning and shape retention, and the two are often contradictory.
The second is the cutting piece dressing technology, which is to obtain the required shape and sharpness of the [url=https://www.auroraabrasive.com/14-inches-cutting-disc/]cutting disc for stainless steel[/url] efficiently and economically. Therefore, in order to improve the efficiency and precision of grinding, especially for the efficient finishing of difficult-to-machine materials, CBN cutting blades are used for efficient and powerful grinding, which makes the powerful grinding break the limitation of traditional grinding, and the productivity is doubled. Some parts are The blank does not need to be roughed and can be directly ground into a finished product.
