As a 'work rest blade' is called the workpiece support in rotationally symmetric centerless grinding. 'Work rest blades' are usually made of hardened tool steel and can be equipped with carbide or PCD for a higher wear resistance.
Centerless grinding or centerless cylindrical grinding is a special form of external cylindrical grinding in which the workpiece is not clamped but placed on a guide ruler (work rest blades) with a wedge-shaped cross-section. In the case of centerless grinding, a distinction is basically made between two process variants, through-feed grinding (also called continuous grinding) and plunge grinding (in-feed centerless grinding). In both centerless grinding processes, the workpiece is fixed in the machine by three essential machine components - grinding wheel, regulating wheel and the work rest blades.
The function of the work rest blades is decisively involved in the final accuracy of the ground workpieces. In addition, multiple workpieces can be sanded on the same rail at the same time with multiple work rest blades during machining. SCHELL offers a comprehensive range of such carbide guide rails for centerless grinding as well as continuous blades, recessing blades and prism blades, (V-blades):
