Passivation machining of diamond grinding wheels

1. The surface wear of grinding wheels can be roughly divided into two ways: abrasive wear and abrasive fragmentation. The so-called abrasive wear refers to the process of grinding with a grinding wheel, where the grinding action between the abrasive particles and the surface of the workpiece being processed, chemical reactions, and deformation of the abrasive particles gradually make the abrasive particles of the grinding wheel dull. Grinding particle breakage refers to more severe grinding wheel particle breakage or the detachment of abrasive particles from the grinding wheel.

2. Grinding wheel abrasive blockage can be divided into two types: embedded blockage and adhesive blockage. Embedded blockage refers to the insertion of ground materials and other debris into the surface of the grinding wheel, blocking its normal chip space and causing the grinding wheel to lose grinding force. Diamond grinding wheel analysis, and adhesive blockage refers to the adhesion of grinding materials to the abrasive particles and their binders. During the grinding process, both embedded and adhesive blockages often occur simultaneously.

3. Surface distortion of diamond grinding wheels is a phenomenon that gradually fails to maintain the desired appearance accuracy of the workpiece during the use of grinding wheels. Especially in forming grinding, the accuracy of the contour shape of the diamond grinding wheel determines the accuracy of the contour of the workpiece to be ground in forming grinding. Therefore, if the grinding wheel undergoes distortion in a certain way, it must be repaired.

Diamond grinding wheel introduction: Diamond is a known hard material in the world, and the grinding wheel made of it has brand grinding function and can resist wear. It has achieved good results in the use of difficult to machine materials such as hard alloys. Especially regarding the metal based diamond grinding wheel, due to its high strength and strong holding force of the bond, it can greatly improve the grinding efficiency of the workpiece, The promotion and use of diamond grinding wheels have become an important symbol of progress in mechanical processing technology.
