Title:
The lathe provided with the amount adjustment mechanism of eccentricity
Document Type and Number:
Japanese Patent JP6207568
Kind Code:
B2
Abstract:
The present invention provides a lathe that is provided with an eccentricity adjustment mechanism that makes it possible for electrical components that are readily affected by the environment to be eliminated from the turntable; for slip rings in particular, which exhibit problems in terms of the durability of signal transmission during high-speed rotation, to be eliminated as well, and for safe and stable adjustment of workpiece eccentricity to be easily achieved. A lathe provided with an eccentricity adjustment mechanism, in which a linear motion guide unit (6) is provided in an inclined state in an engaging part of the center part of a turntable (1) and an axial-direction-movement part (5A) of a center shaft (5); and, due to the center shaft (5) being moved, the turntable (1) moves in the radial direction by the radial pressing force generated by the linear motion guide unit (6) being inclined, and the eccentricity of the workpiece (3) is adjusted.
