Cylindrical grinding is as its name implies the grinding of circular or cylindrical workpieces with the goal of achieving as much "roundness" of the workpiece as possible. Here not only must the outside of a workpiece be machined accordingly but also its inner diameter must be manufactured with extreme precision e.g. on gear wheels.

Cylindrical grinding. Centre type work speeds. The usual range for the grinding of plain cylinders is 60 to 100 surface ft/min but lower surface speeds are necessary where out-of-balance work is being ground. For example the rough grinding of automotive cams should be carried out at 15 to 30 surface ft/min and finish grinding at half this speed.
