A linear motor piston turning and grooving machine (10) for turning non-round diameters and complex shaped pistons (W) in which a pair of oppositely facing CNC turning modules (14, 16) each are aligned with one of a pair of a vertical axis spindles (30, 32) having chucks (26, 28) for each piston (W). An overhead tailstock assembly (34, 36) is centered over each spindle (30, 32). A grooving mechanism (106, 108) is located to the rear of each tailstock assembly (34, 36) and includes a rocking support shaft (110, 112) for bringing tooling (114, 116) into engagement with the piston (W). <IMAGE> |
