摘要: An automatic lathe comprising a workpiece spindle, a compound slide embodying a longitudinal slide and a cross-slide, two primary cam disks seated on a primary control shaft, and transmission levers individually associated with said primary cam disks. The longitudinal slide and said cross-slide each are controlled by said primary cam disks through the agency of the individually associated transmission levers. At least two lathe tool supports are arranged adjacent one another at the compound slide. A control mechanism is provided which can be switched-on during a portion of each work cycle of the automatic lathe for carrying out a thread chasing operation by means of a thread chasing tool clamped in one of the lathe tool supports. The control mechanism embodies an auxiliary control shaft which is or can be placed in driving connection with the workpiece spindle and two auxiliary control cam disks fixedly seated upon said auxiliary control shaft. The auxiliary control shaft is displaceable into an axial position for thread chasing in which the first of such auxiliary control cam disks carries out the control of the movements of the longitudinal slide by means of a plunger associated with said first auxiliary control cam disk and the transmission lever associated with the longitudinal slide and in which the second of the auxiliary control cam disk acts upon the cross-slide by means of a plunger associated with said second auxiliary control cam disk and an additional transmission lever member in order to raise-off the cross-slide from the transmission lever associated therewith for the time duration of each rapid return movement of the longitudinal slide controlled by the first auxiliary control cam disk between successive thread chasing operations in order to lift-off the thread chasing tool from the workpiece.

摘要: An auxiliary shaft (16) mounted coaxially with a main shaft (5) has at the top an eccentric (17) operatively connected via grooving (20, 21) to a tool-fastening plate (13). At the bottom of the auxiliary shaft is a wheel (19) fixed to the eccentric and provided with a recess (18). The recess can engage a fixed lug cam so that a feed motor can cause both the rotary movement of the ball turner and a tool correction effected by a relative rotary movement between the main shaft and the auxiliary shaft. For the sake of accuracy, the angular displacement is limited to an area in which the displacement of the tool-fastening plate caused by the eccentric is substantially linear with the angular displacement. All rotary motions are measured during the operation by a shaft encoder (9) and communicated to a CNC system.

摘要: For high-precision material-removing machining of the lateral surface of a workpiece (1) rotating with the main spindle (3) of a turning lathe, a cutting tool (17) is fixed on a slide (14) which carries out an axial movement synchronized with the rotation of the main spindle by means of a cam assembly (18, 21, 20) control. The shaft (21) of the cam assembly is rotation-tightly coupled to the main spindle by electric means (8, 10).
