Grinding method

摘要

A vehicle rear axle housing has opposite end grind diameters and inboard tooling diameters proximate to the grind diameters. The grind diameters are ground on a centertype grinder by supporting the ends of the housing in both axial and radial directions; supporting the inboard tooling diameters with a floating support means; rotating the housing from one end; and grinding one of the end grind diameters with a rotating grinding wheel. The floating support means acting on each of the inboard tooling diameters opposes the tendency of the housing to sag during the grinding process.
