Studer machine described as a 'hard-fine machining centre' combines cylindrical grinding, hard turning, cutting and drilling.

Enquiries from a variety of sectors plus the experience from already realised projects highlight the expanding spectrum of applications for the Studer S242. It is suitable for machining spindles and guide rods, piston guides and control pistons, pump pinions, armature shafts, keyways, high-speed shafts, guide pins, tool holding fixtures and other precise construction components. Customers come from the machine construction, tool construction, pneumatics/hydraulics or electric/electronics sectors. High flexibility of the S242 also make it interesting for jobshops, single parts (within part families) and small batch sizes.

The parallel aligned grinding heads and tool revolver (if necessary with motor-driven tool positions) enable productive, precise and reliable complete machining in a single clamping. In comparison to conventional methods, an increase in productivity of up to 70% for complex workpieces is considered to be realistic. With two or three cross slides, between 10 and 15 configuration options are possible for external and internal grinding (with up to 3 internal grinding spindles), external and internal hard turning, hard reaming - and with up to 12 motor-driven tool positions for cutting and drilling. The S242 is available with 400 and 1000mm centre distances (two cross slides) as well as with 800mm (three slides).

Characteristics and benefits of the S242 include low primary processing and auxiliary times; premachining close to the final contour; high position accuracy and radial running-true; customer-specific modular assembly of cross slides; quick and flexible changeover; complete machining in a single clamping; automatic control measuring cycles; in-process measurements of diameter and length.
