Abstract
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.
