| 摘要 |
The present invention relates to a processing device for a key groove comprising: a driving shaft; a processing shaft installed to be rotated around an axis in a direction crossing the driving shaft; a driving gear integrally rotating around the axis with the driving shaft; a driven gear transmitting a rotational force of the driving shaft to the processing shaft by the driving gear; and a cutter detachably coupled to one side of the processing shaft by a coupling piece, processing a key groove on an object by integrally rotating around the axis with the processing shaft. The present invention enables the key groove to easily be processed on an inner side of a small diameter. Moreover, the present invention improves processing accuracy by reducing processing tolerances while also reducing processing time. |
