The machine works as follows. The workpiece 9 is installed in the hole of the boot device 2 (Fig. 4 and 5). In the hole. sleeve 12 from the network is supplied working medium. Under the action of the working medium, the sleeve 13 moves in the axial direction until the locking device 14 releases the locking jaws 3 radially and stops the loading device 2o. The cavity of the device 14 is discharged. This part is fixed in the locking device 14. Then the working medium is removed from the sleeve 12o. By the action of the spring, the sleeve 13 returns to its original position, while under the action of its own weight the next part is fed into the place taken and clamped with locking jaws and 3. Turn on the electric motor 15 for driving the rotation of the reels 10 and 11 for the electric motor 35 for driving the rotation of the instrumental 1chp 34.

The drum 10 is shifted to one-eighth of the circumference and stopped by means of the Maltese mechanism (21, 23) to grip the next part. After the part 9 is seized, the drum tO under the action of the Maltese mechanism (21, 23) is moved to another eighth part, and item 9 is included in the processing zone of the tool shpinddel 34, Further movement of the drum 10 is the same way. When the drum 10 rotates by 180 °, the part 9 is intercepted by the locking device 14 of the drum 11 “. Through the hole in the hub 12 of the drum 11, the built-in rotary actuator 41 of the rotating spindle 40“ U of the mechanism of the spring mechanism rotates the drum into the zone processing tool of the spindle 40. Drum vaets. When this happened, the next 10 parts 9. The reel of the drum 11 also occurs when rotating by 270 ° a vacuum from the cavity of the fixture 14.
