Beijing Demina company produce high quality and strong rigidity tool grinding machines for PCBN and PCD tools. The tool grinder has high machining accuracy and low Ra of surface roughness. They have strict inspection standards for machine tools. Mainly according to the accuracy of all kinds of products, manufacturing, and acceptance of technical requirements and product quality grading standards, focusing on testing the accuracy and performance of products. Due to the high hardness of diamond material (PCD) and the rapid wear of grinding wheel, the system can automatically detect such wear and make compensation, which can maintain the dimensional accuracy of grinding for a long time.
