There may be many people who have not heard of the Diamond cup grinding wheel . Today we will talk about the choice of the concentration of the Diamond cup grinding wheel.
Concentration is a unique property of diamond grinding wheels and cubic boron nitride grinding wheels. It refers to the content of diamond or cubic boron nitride per unit volume in the working layer of the grinding wheel. Concentrations are 25%, 50%, 75%, 100%, 150% and 200%. The concentration is large, and many abrasive particles are participating in the cutting so that the cutting thickness and grinding force are reduced, the grinding temperature is lowered, and the grinding ratio is increased. For example, when grinding cemented carbide, the concentration is increased from 25% to 100%, so that the abrasive grains fall off prematurely and the abrasive grain consumption increases. Under normal circumstances, resin bond abrasive tools should be selected at a concentration of 50% ~100%; bronze bond abrasive tools should be selected at a concentration of 75% ~150%; electroplating bond abrasive tools should be selected at a concentration of 200%; coarse particle size, shape grinding and For high-efficiency grinding, high concentration should be used.
