Centerless Grinding: Not Magic! : Modern Machine Shop

Dec 15, 2000Infeed centerless grinding is analogous to plunge grinding on a center-type machine. The work is placed on the blade, and the regulating wheel moves into a programmed feed to begin the grind. The work does not move axially in this type of centerless grinding.

Thrufeed centerless OD grinding: Parameter relationships

The centerless process is commonly used for high volume production, and it’s also easily used for low volume production because the machine setups are fairly simple. In thrufeed centerless OD grinding the workpiece passes between two wheels, a grinding wheel and a regulating wheel (as illustrated in the diagram below). Both wheels rotate in

Speeds and feeds Wikipedia

Grinding wheels are designed to be run at a maximum safe speed, the spindle speed of the grinding machine may be variable but this should only be changed with due attention to the safe working speed of the wheel. As a wheel wears it will decrease in diameter, and its effective cutting speed will be reduced.
