Metalworking Fluids - Grinding Grinding. We understand that grinding fluids are crucial in the grinding process. Not only are they needed to reduce friction, but also for their ability to extract heat from the work zone and maximize material removal.
During the lapping process, the disc is charged with small amounts of a hard abrasive such as diamond or silicon carbide. Lapping discs can be made of many different materials cast iron and plastic are used most commonly. Lapping produces a flatter specimen surface than grinding, but it does not remove metal in the same manner as grinding.
Basically, it is a combination of an electrochemical process and a grinding process used for metal removal. You may also hear it referred to as anodic machining or electrolytic grinding. In the process, the part of a cathode is played by the grinding wheel, while the

Truing operations deal with the form or profile of the grinding wheel. When truing a new abrasive wheel, the grinding face is altered to allow the abrasive product to do what it needs to do. Routine truing during the grinding process corrects the wheel profile and compensates for form loss as the wheel breaks down under regular use.
