What is a Grinding Wheel?
A grinding wheel is a precision tool with thousands of cutting points on its surface, abrasive grains that are held in place by a bond matrix (hence these are known as bonded abrasives) and separated by pores. These pores are hollow spaces between abrasive grains and the bond , which help with the clearance of discarded metal chips in the grinding process. When the wheel is in use, the abrasive grains cut into the material that is being ground, removing the unwanted surface material in small chips.
During grinding, the cutting points on the abrasive grains are worn flat and becoming increasingly blunt. At the same time, the increased friction causes a build-up of heat, which fractures the abrasive grain and exposes new cutting edges or begins to disintegrate the bond bridges that hold the abrasive grains in place.
In normal vitrified grinding, the wheel has to be dressed using a dressing tool. By varying the properties of the abrasive, the type of bond, the wheel’s construction, it is possible to produce grinding wheels with a vast range of different grinding characteristics.
