United Grinding (Studer) vs United Grinding (Walter) · CNC Grinding Machines
Summary
The Studer Favorit and the Walter Helitronic Vision 400 are both CNC grinding machines from the United Grinding group, but they do different jobs. The Studer Favorit is a cylindrical grinder for external grinding of shafts, offered with Z travel of 500 mm, 800 mm, 1,150 mm or 1,750 mm. The Walter Helitronic Vision 400 is a tool grinder for fluting carbide tools and grinding large cutters, with 700 mm (27.6 in) of Z travel.
The Studer Favorit carries the heavier work, 80 - 150 kg (176 - 330 lb) depending on model against 50 kg (110 lb), and the larger wheel, 500 mm (20 in) against 254 mm (10 in). The Walter Helitronic Vision 400 has the stronger spindle, 33 kW against 11.5 kW (15.4 hp), and the faster rapids, 50,000 mm/min (1,969 ipm) on all axes against 15,000 mm/min. Both run on the C.O.R.E. platform, the Walter with a Fanuc control.

Advantages
Studer Favorit
- Workpieces of 80 - 150 kg (176 - 330 lb) depending on model, against 50 kg (110 lb)
- Grinding wheel up to 500 mm (20 in) in diameter against 254 mm (10 in)

Verdict
Choose by the part, because these machines do not overlap. A shop grinding shafts, in single parts or batches, needs the Studer Favorit: it takes workpieces of 80 - 150 kg depending on model and a 500 mm (20 in) wheel, with a choice of Z travels. A shop making or sharpening cutting tools needs the Walter Helitronic Vision 400, whose 33 kW spindle and 50,000 mm/min rapids suit fluting carbide tools from solid.
