Wheel profile permitting grinding on both sides of collar - consists of two pairs of bevel segments dressed symmetrically about middle plane of wheel

摘要

The configuration is that of conventional cylindrical grinding, the workpiece being supported between centres (7, 8). Conical surfaces are dressed on the contact face of the grinding wheel (1), which during grinding is set with its axis inclined to the direction of table traverse (12). Wheel surface (22) is used to grind cylindrical surface (13) and wheel surface (23) to grind collar face (16). The wheel axis is then pivoted approx. 90 deg in readiness for grinding on the other side of the collar. Cylindrical surface (14) is ground with wheel surface (26) and collar face (17) with wheel surface (Z+). The method is effectively applied using CBN or diamond wheels with a narrow grinding contact face. USE/ADVANTAGE - Grinding machine workpiece does not require to be turned end to end between centres. Greater accuracy and reduced downtime.
