Working apparatus

A working apparatus, comprising:

• a base stage;
• work hold and rotation means mounted on said base stage, serving for holding and rotating a work about a work rotation axis;
• working means, mounted on said base stage, movable toward and away from said work, and provided with a working tool;
• press means for pressing said working tool toward said work via said working means;
• and
• trace means, mounted on said working means, being pressed toward said work together with said working tool by said press means, said trace means being in contact with said work, and moving with said working means as a whole in forward and rearward directions towards and away from, respectively, said work, according to an outer shape of said work,
• wherein when said press means presses said working tool and said trace means toward said work when said work is in rotation, said working tool applies deburring and chamfering to said work, and said trace means becomes in contact with said work and controls deburring and chamfering of said working tool at a predetermined constant volume, so that deburring and chamfering on the whole circumferential surface of said work may be carried out at said predetermined constant volume,
• wherein said work hold and rotation means is provided with a work rotation axis angle adjustment mechanism, serving for adjusting the angle of the rotation axis of said work in a state of holding said work, and is also provided with a locking means for fixing the angle of the rotation axis of said work.
