FIELD: metal working.
SUBSTANCE: invention can be used, in particular, in turning of stepped eccentric parts having shifted longitudinal axes of steps with eccentricity from 0 mm to 10 mm. Device comprises a cutting tool mounted on a lathe support, and a fixture for fixing a part in a three-jaw chuck of the machine, note here that said appliance is composed of interconnected additional three-jaw chuck and two intermediate eccentric elements arranged to turn relative axially. One of said elements is made in the form of an eccentric faceplate with a shank, and the second is in the form of a split eccentric bushing, wherein the additional three-jaw chuck is fixed by screws on the faceplate, which by means of fixing screws is connected to eccentric bushing with arrangement of faceplate shank in bushing. On the eccentric bushing there are indicative marks with a digital designation, and on the eccentric faceplate there is a control mark.
EFFECT: use of the invention allows simplifying the process of processing eccentric parts and expanding the technological capabilities of the device.
