Verdict
These machines do not compete for the same work. A shop grinding heavy shafts, rolls and large-diameter parts needs the Studer S41, with its 250 kg (550 lbs) load, 508 mm (20 inch) wheel and Z travel of 1'150 mm or 1'750 mm. A shop producing or sharpening cutting tools needs the Walter Helitronic Vision 400, whose 33 kW spindle is aimed at fluting carbide from solid on tools and cutters up to 50 kg (110 lb).
