Title:
LATHE WITH ECCENTRICITY ADJUSTMENT MECHANISM
Document Type and Number:
Japanese Patent JP2017077598
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lathe with an eccentricity adjustment mechanism which eliminates an electric component that is easily affected by environment from a turntable, can also eliminate a slip ring causing a problem of durability of signal transmission, particularly, in high-speed rotation, and easily achieves safe and stable eccentric adjustment of a workpiece.SOLUTION: In a lathe with an eccentricity adjustment mechanism, a direct-acting guide portion 6 is provided on an engagement portion of a central portion of a turntable 1 and an axial movement portion 5A of a center shaft 5 in an inclined state, the center shaft 5 is moved, and thereby the turntable 1 is moved in a radial direction by a pressure force in a radial direction generated by inclination of the direct-acting guide portion 6, and the eccentricity of a workpiece 3 is adjusted.SELECTED DRAWING: Figure 2
