Abstract

A multispindle automatic lathe has a main shaft drive motor (M3) for driving spindles (13) via a driving power transmission system (2a, 12, 14, 15, 20, 21, 22, 27, 28, 31), a feed and index driving motor (M2) operating a low and high speeds in timed sequence for feeding a plurality of cross tool slides (16) via a feed driving system (3a, 61, 62, 64, 65, 67, 68, 69, 70) and indexing the spindle carrier (11) via an index driving system (62, 71, 72, 73, 74, 75, 76, 77), and a feed and index drive motor (M1) for feeding a plurality of end tool slides (18) via a feed driving system (4a, 18a, 78, 79). A ring gear (65) is disposed around and in an independently rotatable form separate from the spindle carrier (11), a cam shaft (68) for each cross tool slide has mounted thereon a gear (70) engaging the ring gear (65) and a cam (69 ), and a cam roller (67) is disposed on each cross tool slide (16) and engages with the cam surface of a respective cam, whereby rotation of the cams by the feed driving system reciprocates the cross tool slides in directions transverse to the spindle shaft. An index gear (77) on the spindle carrier is rotated in timed sequence with the cross tool slides by the feed and index drive motor.
