When used in lathe processing, the eccentric sleeve can adjust the coincidence position of the drill bit axis and the spindle axis.
The eccentric sleeve can coincide the axial direction of the drill bit with the axial direction of the spindle within 0.2mm (rotate the eccentric sleeve counterclockwise to expand the aperture adjustment).
Normal aperture D tool and turret normal aperture D+0.2.Axial coincidence.
During milling machine processing, if you need to change the diameter of the normal processing hole, you can adjust the axial position of the eccentric sleeve.
If you want to enlarge the hole diameter: rotate the sleeve clockwise; if you want to reduce the hole diameter, turn the sleeve counterclockwise, as follows: Drill diameter: 30mm.
