PURPOSE:To entirely eliminate interference between a tailstock and drive mechanism of rotary tools and simplify structure thereof, by arranging all the drive mechanisms of rotary tools to be contained within the multiple tool rest and the rotary turret so as not to be projecting outwardly of the multiple tool rest. CONSTITUTION:In a multiple tool rest 1 for a numerically controlled lathe with tools 3, 3' and a turning tool attached thereto, a power transmission path transmitting a rotary drive only to the tool 3 which is at a machining position is formed by means of an arrangement of a drive shaft 7 passing through a turret turning shaft 4, a drive gear 8 fixedly attached to the end of the shaft 7 within a turning turret 2, driven gears 11, 11' mounted along the circumference of the turret 2 for rotating the rotary tools, and intermediate gears 10, 10' operably born for sliding in the axial direction between the gear 8 and the gear wheels, 11, 11'. By this design, the drive mechanisms of the rotary tools are entirely prevented from interfering with the tailstock and simplified in their structure. |
