Cold rolling of tooth contours from solid blanks - workpiece is plunge-cut to profile depth
Реферат: The procedure is for the cutting of parallel profiles from solid blanks, by displacing material from the profile base to the workpiece surface via regular stroke-like rolling steps of profiled rollers, held in driven rolling heads. At the beginning of the rolling process, the solid workpiece is plunge cut to profile depth, by synchronous feeding of two opposite rolling heads. The workpiece is displaced in a straight line during plunge cutting. In the case of workpieces with collar and profiles extending to the collar, the piece is plunge cut to close to the collar, and is drawn, after the profile depth has been reached.
