Moresuperhard provide quality cnc diamond grinding wheel for grinding rotary cutting tools.1A1,1V1,11V9,12V9 abrasives grinding wheel suit for anca,walter,ewag cnc grinding machine.1. Suitable for high-efficiency grinding processing with rapid feed.2. Good wear resistance and shape retention.3. It has good self-sharpening properties, generates less heat during grinding, reduces burns on the workpiece, and meets the high-precision requirements of the tool.4. No clogging, easy to trim, extend the trimming cycle and reduce processing costs. 5. The cutting edge quality of the grinding workpiece is consistent and the smoothness is high, which ensures stable quality when processing downstream products.
At present, the main diamond processing methods include mechanical polishing, thermochemical polishing, tribochemical polishing, laser polishing, ion beam polishing and chemical mechanical polishing.Due to the anisotropy of diamond, "hard" and "soft" polishing directions have completely different material removal rates.Experimental results show that atomic-level roughness values can be obtained in a shorter time by mechanical polishing in the crystallographic directions <100> and <110> or in another direction deviating from <110> at an angle not exceeding 20°.
