Grinding Machines an overview ScienceDirect Topics

Grinding machines, like broaching machines, operate over a range of speeds depending on the type of machine being used.These range from approximately 1250 to 2000m min 1, although in high speed grinding speeds of up to 5400m/min are achievable (Schey, 1987).The two most common grinding applications are cylindrical grinding and surface grinding.

Speeds and feeds

A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation. The cutting conditions will affect the value of this surface speed for mild steel.
