The CBN Grinding wheel has very good performance characteristics and is trusted by consumers in the market. And the matrix material as the basis for connecting the grinding layer, Its choice will have a very large impact on the quality and accuracy of the grinding wheel.
For the CBN grinding wheel, We choose the matrix material, should be based on the material cost, select the density of small, small centrifugal deformation, high-speed rotation when the thermal expansion of relatively small material.
Matrix material at the grinding wheels is made of aluminum, or steel processing, the main role is to support the working layer and installed abrasive. The binding agent of grinding wheel is mainly made of Resin powder, metal powder, ceramic or electroplated metal for polishing and grinding.
Therefore, if the use of ceramic binder, it should use aluminum matrix material; For CBN grinding wheel with Resin powder as binder, aluminum matrix material can be used, or steel matrix material can be used, but by contrast, we can see that in the resin powder binder, these two materials have different options, Aluminum substrate material usage rate of about 80%, if the substrate material thickness of 3mm or more, it is very suitable, The utilization rate of steel base material is about 20%. If the base material thickness is below 3mm, it is suitable for steel substrate material. Finally, if the use of metal powder and electroplating metal as a binder, They are very suitable for steel matrix material.
