Advantages
Studer Favorit
- 11.5 kW (15.4 hp) spindle power against 8 kW (10 hp)
- Suited to external and plunge grinding of shafts, in single parts and batches
Studer S33
- B axis for grinding diameters and shoulders in one clamping
- Suited to shafts that would otherwise need a second setup
Verdict
Size does not decide this pair: travels, center height and center distances are the same. For straightforward external and plunge grinding of shafts, the Studer Favorit fits, and it lists the higher spindle power at 11.5 kW (15.4 hp) against 8 kW (10 hp). For shafts where diameters and shoulders must be ground in one clamping, the Studer S33 and its B axis fit. Both list workpieces up to 150 kg, on the Studer Favorit depending on model.
