Dalang gold research hardware production of resin diamond grinding wheel thinnest up to 0.3mm, widely used in optical projection curve grinder or other precision grinding machine on the processing, grinding.

The grinding of diamond is carried out on a cast iron grinding disc. The diameter of the grinding disc is about 300mm, and the shape, size and proportion of the pores in the material are optimized by grinding high diamond cast iron. The surface of the grinding disc is ground with diamond grinding powder, the particle size can be from less than 1μm up to 40μm. Coarse-grained diamond powder has a high grinding rate, but the grinding quality is poor, so coarse grinding is generally used coarse powder, and fine grinding is used when the size of less than 1μm fine powder. Before grinding, the first diamond powder and olive oil or other similar substances mixed into grinding paste, and then coated on the surface of the grinding disc, placed for a period of time so that the grinding paste fully penetrate the grinding disc cast iron pores, and then a larger diamond in The surface of the grinding disc is pre-ground back and forth to further strengthen the mosaic effect of the diamond powder in the cast iron porosity. Grinding, the diamond will be ground in the general embedded in the tin bucket, only to show the need to grind the surface. The grinding speed of the grinding disc is about 2500r / min, and the grinding pressure is about 1kg / mm2.
