PURPOSE:To make end deburring for a wide variety of gears performable with one unit device in a simple program change alone, by expanding an interval between deburring discs wide, and varying the expanded width automatically in a manner conformable to tooth width and form. CONSTITUTION:A width expanding body 45 is attached to a coupling plate 43, and disc holders 26 and 27 are attached to holder holding plates 19 and 20. With the smallest gear in tooth width among gears WA-WD as a criterion, the width expanding body 45 is moved so as to cause a deburring disc 61 to come into contact with the side of the gear. At the time of deburring, it is carried out by resilient force of a coil spring 60. Therefore, deburring can be done so efficiently by only adjusting an opposed interval between two deburring discs according to gears different in technical data. |
