Quick Detail:

Internal grinding is used for the finishing of internal holes and is carried out on an internal grinding machine or a universal cylindrical grinding machine. Through holes, non-through holes, cylindrical or conical holes, stepped holes and hole end faces can be processed.

Description:

The commonly used shapes of internal grinding wheels are flat and cup (see the figure below). Among them, the flat grinding wheel is the most commonly used, and the cup-shaped grinding wheel is more advantageous for grinding stepped holes and sections.

How to choose internal grinding wheel
The selection is based on the workpiece hole, and there should be an appropriate ratio between the two. Usually the diameter of the grinding wheel is 0.5~0.9 of the hole diameter.
