To provide an apparatus that may impart a complicated bend deformation to an object to be machined such as a ceramic bar elongated in one direction or the like, and may reduce the non-uniformity in machining amount of the object to be machined upon the machining work of the object to be machined, specifically a correcting mechanism for deforming the object to be machined together with a jig holding the object to be machined is provided in a machining apparatus. The correcting mechanism includes a base, a plurality of levers provided at first ends with pins, a shaft fixed to the base for rotatably supporting the levers, and a plurality of correcting drive means coupled to second ends of said levers for pivoting the levers to the shaft to thereby pivoting the pins. The jig includes a plurality of load receiving portions arranged in a holding portion elongated on one direction for holding the object to be machined whereby portions corresponding to the load receiving portion in the holding portion are deformed together with the object to be machined in accordance with pivoting of each pin.

Machining apparatus for workpiece and method therefor

When electric elements are formed on a ceramic bar or the like, the positional displacement of the respective elements occurs due to a division exposing process or the like. An object of the present invention is to provide a device and a method which unify the non-polished portion of the respective elements by conducting polishing while a complicated deformation or the like is given to the ceramic bar. To achieve this object, the ceramic bar or like is held by using a jig, and a plurality of loads are applied to portions of the jig where the ceramic bar or the like is held, to thereby deform the ceramic bar or the like and polish the element in that state. In this situation the load applied points are disposed so as to avoid the boundaries of the division exposure.
