Title: Accurate machining device
Inventor: NAKASUJI TOMOAKI
IPC: B23C3/28
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To aim at the machining with high cylindricity and high straightness by preventing the relative movement between the center axis of the relative rotation and a machining point. SOLUTION: Since output of a displacement sensor 24 and driven quantity of a piezoelectric element or a magneto strictive element 22 form a closed loop, rotation accuracy of a shaft B can be controlled by the resolution of the displacement sensor 24. Since the piezoelectric element or the magneto strictive element 22 is used for drive, high-speed response is possible and high rigidity can be secured. Correction by this mechanism has the fine resolution for each second. Even if a work 1 and a tool 5 are relatively moved during the machining, relative movement between a machining point and the center of rotation of the shaft B is prevented during that time. The shaft B is arranged so as to be synchronously moved with the movement of the tool 5.  Two of the piezoelectric element and the magneto strictive element 22 are arranged so as to provide the high responsiveness independently of the driving direction.
