Grinding wheels are made of abrasive particles held together by a bonding material. As the wheel spins, the abrasive particles makes contact with the work piece at high speed and repetitions and in the process cutting away material from the work piece. Diamond grinding wheels use very small diamond particles as the abrasive material.
Glazing is what happens when the bonding material of the grinding wheel melts and covers the diamond particles. When this happens, the grinding wheel becomes inefficient or completely incapable of material removal. Glazing can be prevented by regulating heat during operation. There are several means of heat regulation.
One is the use of the right speed settings. Due to the differences in which grinding wheels are manufactured, different brands of grinding wheels can behave differently in terms of heat generation. Follow the right speed settings for use on specific work piece materials as per instruction of the manufacturer.

Another method of heat regulation is the use of coolant. During use, coolant is allowed to flow continuously over the grinding wheel to absorb and transfer heat away from it. The rest of heat regulation involves the operator and depends largely on experience. Some examples are to not use the grinding wheel so long at a time and not to apply more pressure than what is necessary.
