Shaft grinding machine JUTWIST 2000

CNChigh-speedhigh-capacity

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. Highlights Pre- and finish-grinding in a single setting Long service life for the tools Low tool costs High quality (roundness, concentricity, dimensional accuracy, diameter tolerance) Achievable surface quality of Rz 1 possible following the finish-grinding AQM traverse the process direction <20 Process-reliable, high repeat accuracy Integrated deburring station Fast machine changeover Thanks to the geometry calculation of the multi-tooth and single-tooth grinding wheel, the grinding wheel is perfectly shaped for the thread of the workpiece. The electroplated profile grinding wheel that is used for the pre-grinding allows for a high cutting capacity and is ideal to process soft but also hardest materials.The threads are finish ground with aluminum oxide, this results in workpieces with outstanding geamoetry and surface quality. Equipment and Options DEBURRING STATION With the integrated deburring station, JUNKER offers the reliable and process-reliable removal of the broken tooth on the worm shafts in parallel to the grinding process. The workpieces are transported directly to the clamping system via an internal loading gantry.
