Abstract
Official abstract text for this publication.
A machine tool includes a main spindle ( 10 ) which holds a workpiece ( 200 , object to be machined) and is rotatable about the shaft center (C 1 ), a main spindle motor ( 20 , main spindle driver) which rotates the main spindle ( 10 ), a rotary guide bush ( 30 , eccentric guide bush) which supports the workpiece ( 200 ) projecting from a leading end of the main spindle ( 10 ) to be rotatable in a state of being eccentric relative to the shaft center (C 1 ) by a length E, a guide bush servomotor ( 40 , guide bush driver) which rotates the rotary guide bush ( 30 ) about the shaft center (C 1 ) in synchronization with the main spindle ( 10 ), and a controller ( 50 ) which controls the rotation and driving of the guide bush servomotor ( 40 ), so as to selectively switch between the rotation state and the stop state of the rotation.
First claim
Opening claim text (preview).
The invention claimed is: 1. A machine tool comprising: a main spindle having a shaft center which fastens an object to be machined such that the shaft center is aligned with a center of the object to be machined, and rotates integrally with the object to be machined; an eccentric guide bush which supports the object to be machined projecting from a leading end of the main spindle in a state of being eccentric relative to the shaft center of the main spindle, wherein the eccentr…
