Hermle C 400 vs Hermle C 42
Hermle vs Hermle · 5-Axis Machining Centers
Summary
The Hermle C 400 and the Hermle C 42 are Hermle 5-axis machining centers of similar size. The C 400 travels 850 x 700 x 500 mm against 800 x 800 x 550 mm on the C 42, so it is longer in X but shorter in Y and Z. Both start at 15,000 rpm, the C 400 with 18,000 or 20,000 RPM optional, the C 42 with spindles up to 25,000 rpm (HSK A 63) or 42,000 rpm (HSK E 40).
The C 42 lists 31 kW and 194 Nm with its 15,000 rpm spindle, against 20 kW (27 hp) and 173 Nm (128 ft-lb) on the C 400. It also carries 42 pockets standard against 38 tools, with magazines up to ZM 528. The C 400 is slightly lighter at 12,500 kg (27,558 lb) against approx. 13.5 t.
