Passivation machining of diamond grinding wheels

1. The surface wear of grinding wheels can be roughly divided into two forms: 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 grinding wheel abrasive particles blunt. 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 the abrasive particles and their binders to the ground material. During the grinding process, both embedded and adhesive blockages often occur simultaneously.

3. The 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 summarized shape of the diamond grinding wheel determines the accuracy of the summarized workpiece in forming grinding. Therefore, if the grinding wheel experiences distortion in form, it must be repaired.

Diamond is a well-known hard material in the world, and the grinding wheels manufactured from it have brand grinding functions and wear resistance. They have achieved good results in grinding difficult to machine materials such as hard alloys. Especially for metal based diamond grinding wheels, due to their high bond strength, strong holding force, and can greatly improve the grinding efficiency of workpieces, The promotion and use of diamond grinding wheels have become an important symbol of progress in mechanical processing technology.
