PURPOSE:To chamfer the tooth end faces or widthwise end face side edges of a cylindrical gear, by utilizing a roll-press chamfering method in which compression deformation is made by the same measure as that of a rolling method. CONSTITUTION:A chamfering tool 1 is attached to the tool shaft (not shown) by means of an attaching hole 7 formed in the tool 1. A gear to be chamfered is attached to a fixture such that the axis of the gear is set in parallel with the axis of the tool 1. Roll-press teeth 2a, 2b are meshed with the tooth end faces of a gear 9 with the gear 8 being clamped therebetween. This meshing condition may be adjusted by spacers 5a, 5b. In accordance with a chamfering shape which is to be applied to the gear teeth, the tooth end face side edges of the gear is chamfered. |
