Studer S242

Studer Combination Hard Turning and Grinding Machine Studer S242 The combined machining system for hard turning and grinding enables rational hard-fine applications for both shaft and chuck work pieces. The Granitan® S103 inclined-bed machine base meets the following special requirements: - Good accessibility - Optimum chip discharge into the integrated chip conveyor - Effective vibration damping - Highest possible temperature stability The standard versions of the S 242 have either two or three center supports to accept the grinding or turning/milling tools. The distance between centers is 400 mm or 650 mm. Depending on the application, workpieces having a length of up to 1000 mm can be machined. The grinding tools have a diameter of 400 mm and the turning tool turret can accommodate up to 8 tools, including the optional live tooling.
