Abstract: The present invention aims to provide a working device for deburring or chamfering easily, for example on the both sides of a gear, and for desired deburring or chamfering effectively on a large-sized gear, and comprises a base stage, a workpiece hold and rotate device mounted thereon for holding and rotating a workpiece, a working device mounted on the base stage and movable to and from the workpiece and having a working tool for working against obverse and reverse sides of the workpiece, a pressing device for pressing the working device toward the workpiece, and a tracing device on the working means, composed of a workpiece obverse side tracing member corresponding to the obverse side of workpiece, and a workpiece reverse side tracing member corresponding to the reverse side of workpiece, for moving the working device in forward and rearward directions by becoming in contact with and tracing shape of the workpiece.

Abstract: A working apparatus, provided with a base stage, work hold and rotation device for holding and rotating a work, working device movable toward and away from the work via slider mechanism and having a working tool, press structure for pressing the working tool toward the work via the working device, and trace device pressed toward the work together with the working tool by the press structure and in contact with the work and moving the working device as a whole in forward and rearward directions according to outer shape of the work. By pressing of the pressing structure, the working tool deburrs and chamfers under control of working volume by the trace device. The work hold and rotation device has work rotation axis angle adjustment mechanism, for adjusting angle of rotation axis of the work by holding the work. The working apparatus can precisely deburr and chamfer complicated shape of work such as worm gear.
