Innovative Worm Screw Power Skiving (WSPS) technology from Affolter Technologies SA(Malleray, Switzerland) can finish a high precision worm in only six seconds as opposed to worm hobbing, where every piece takes 25 seconds - meaning manufacturers of automotive and aircraft components can be four times faster. WSPS focuses on small worms with a module of 0.3 to 1.5 that are used in car seats or trunks, among other applications. Unlike worm hobbing, where the hob turns much faster than the workpiece, WSPS inverts the process: the workpiece turns extremely fast with two new spindles up to 12,000 rpm, while the cutter turns much slower. "Only higher quality equipment, such as our Affolter AF100 plus and AF110 plus gear hobbing machines, can reach this speed and provide the necessary stiffness at the same time," says Vincent Affolter, the managing director of the company.
