Selection and use of grinding 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
