What is Cylindrical Grinding - Steps in Cylindrical Grinding
In cylindrical grinding operation, the work is mounted between two centres and is rotated. A grinding wheel is mounted on a spindle and revolves at much higher r.p.m. than the work. The work centres are mounted on a table which can traverse at various feeds so that the entire length of the work passes to and fro in front of the wheel.

GRINDING FOR TOOLMAKING
Grinding stresses can be reduced by repeated tempering after grinding. In this case, the tempering temperature should be about 30°C lower than the last tempering temperature in order to prevent loss of workpiece hardness. Another way to reduce grinding stresses is to peen the ground parts (see Figure 5.)
