PURPOSE:To maintain uniform burr removal from a work by permitting adjustment of the position of a grinder which corresponds to the reduction of the diameter of the grinder due to wear-out, through the unidirectional adjustment in a slide for adjusting grinder. CONSTITUTION:A burr removing apparatus equipped with a disc-shaped grinder is provided with a rotary table 3, on which a rotary shaft 5 is slidably inserted into the center hole 4 located on the front surface of a horizontal slide 1. A grinder head 14 is installed onto an arm tool 13, and said head 14 is constituted of a motor 15, a rotary driving shaft 16 which projects from said motor, and a disc-shaped grinder 17 fixed to the top edge of said shaft 16. When the diameter of the grinder is reduced through the wear-out in the burr removing operation, the position of the grinder can be adjusted through unidirectional operation in which a rotary plate 12 is turned, and the grinder 17 is shifted in the direction of contact with work by the length of the radius of the grinder which is worn- out at a fixed angle. Thus, uniform burr removal operation can be maintained. |
