The high-speed grinding machine JUTWIST and JUMAT of JUNKERs 2000 platform is dedicated to manufacture worm shafts and work shaft profiles from blank. The worm shafts are used, for example, in the automotive industry and in general mechanical engineering, where they are used for transmission and power transmission, and are fitted in various steering systems, servomotors and parking brakes, for example. The production process can be easily transferred to other, geometrically similar workpieces.
