Abstract

A multi-head programmed internal grinding machine for grinding journals in sequence, designed to provide the optimum diameter grinding head for two thirds of the bore for each operation, incorporates a circular table (26) with peripherally mounted grinders (34) of varying diameter at equally interspaced angular stations, the rotation of the table being controlled incrementally. The machine grinds a sequence of workpieces without intervention, and incorporates mechanisms for sliding the tool insertion table, auto-diamond setting and cyclic programming of operations. The turn-table (26) can be rotated by a jack (35) actuated rack (36) and pinion (37).
