PROBLEM TO BE SOLVED: To solve a problem of varied and uneven finishing, and high defective fraction due to deburring finishing by manual procedures, which is adopted since an expensive NC machine tool increases the cost of work. SOLUTION: This copy grinding device is provided with a main motor 1, a first rotary shaft 2, a first bevel gear 3, a cam mechanism 4 consisting of a pair of cam plates 4A, 4B, a second bevel gear 5, a second rotary shaft 6, a placing base 7, a master M, a workpiece W, a copying contact part 8, a grinding device body 9, a rotary tool 10 for grinding, a control roller 11, a control lever 12, an air valve 13, and an air tube 14. The air tube 14 is connected to an action mechanism 15, and moreover, the pair of cam plates 4A, 4B form large diameter peripheral parts 4Aa, 4Ba and small diameter peripheral parts 4Ac, 4Bc via steps 4Ab, 4Bb. The air valve 13 is opened or closed by the steps during one rotation of the first rotary shaft 2, and the action mechanism 15 is activated by pressure air. COPYRIGHT: (C)2008,JPO&INPIT
