- 60 m/min (2,362 IPM) rapid traverse against 15,000 mm/min (590 inch/min)
Studer Favorit
- Z travel from 500 mm (19.7 inch) to 1,750 mm (68.9 inch) depending on version, against 200 mm (7.9 in)
- Listed for external grinding of shafts, including plunge grinding
- Suited to single parts as well as batches
Verdict
Pick by part shape. The EMAG VSC 250 fits short chucked parts that are turned and bore-ground in one clamping, and its 39 kW (52 hp) spindle and 60 m/min (2,362 IPM) rapids suit production work. The Studer Favorit fits shafts that need external grinding, as single parts or batches, in whichever of its four Z travels from 500 mm (19.7 inch) to 1,750 mm (68.9 inch) matches the part length. A shop that needs one will not be served by the other.
