<p>PURPOSE:To perform accurately an abrasive finishing of a denture in the same shape as that of a denture model by fixing a denture to be abraded on a denture fixing part, fixing a specified copy mold on a copy mold fixing part and moving a stylus along the copy mold. CONSTITUTION:A denture 100 wherein a positioning pin 103 is buried in a denture base is fixed on a denture fixing part 5 and a copy mold 110 formed in a finishing shape of the denture 100 is fixed on a copy mold fixing part 6. An abrasive work can be performed by mounting a stylus holder 84 on a stylus mounting part 20, mounting an abrasive driver 67 on an abrasive driver mounting part 19, bringing a stylus 86 into contact with a specified part of the copy mold 110 and moving it along the surface of the copy mold 110. Movement of the stylus 86 is transmitted to a mounting part 19 of the abrasive driver through a holding member 76, a transverse member 75 and a connecting rod 61 and furthermore, transmitted to a driver 67 through a transverse member 56 and a holding member 57 of the mounting part 19 and an abrasive wheel 69 fixed on the apex of a rotating shaft 68 of the driver 67 performs the completely same movement as the movement of the stylus 86.</p> |
