| 摘要 | PURPOSE:To remakably improve the machining efficiency of the teeth of a gear, by cutting in a starting gear material with groove machining tools a set of two deep grooves forming together a V-shape and removing a portion corresponding to each space between each two adjacent teeths to be formed, including the deep grooves. CONSTITUTION:Prescribed cuts are given to each tool main body 6, and a main body 1 of a main spindle is allowed to make the feed motion in an arrow direction A while rotating the tool main body 6, then one of the deep grooves 20 is cut by the left tool main body 6 of a groove machining tool 2 into a gear material 17 while the other deep groove is cut by a cutting edge 7 of the right tool main body 6, finally a portion corresponding to a space part 21 between two tooth to be formed, including V-shaped two deep grooves 20, is removed. Hereafter, the left and right main bodies 1 of the main spindles are moved backward from the gear material 17, during which the gear material 17 is index rotated by one pitch of the gear, then the cutting operation of deep grooves is again performed to successively form teeths. | ||||||
