FIELD: process engineering.
SUBSTANCE: tooling comprises float chuck mounted on front support spindle on holder arranged on support, expanding mandrel to mount tube by spring creating radial force. Note here that mandrel mounting surface arranged perpendicular to tube axis stays in contact with tube in one plane with cutting tool. Besides, it comprises balls arranged regularly in separator to displace radially resting upon two taper surfaces and to locate tube inner surface. Said balls are integrated with sleeves moving axially relative to each other and mechanism to adjust distance. Note here that said spring is located to adjust axial force and transform it into radial force by said taper surfaces and balls.
EFFECT: higher accuracy of tube fixation and reduced dynamic loads.
