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 Studer S242 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.
