Our best estimate for a 5-axis machining center in this class — not a quote from Hermle. Configuration moves it a long way.

Overview

The Hermle C 42 U GEN2 machines workpieces up to Ø 800 × H 560 mm (Ø 31.5 × H 22 in) and 1,400 kg (3,086 lb) on a Ø 800 × 630 mm (Ø 31.5 × 24.8 in) swivelling rotary table. Travels are 800 mm (31.5 in) in X and in Y and 550 mm (21.7 in) in Z.

The horizontal travels equal the workpiece diameter, and the Z travel is close to the full part height. Table clearance is max. 700 mm (27.6 in), so a part at the full 560 mm leaves limited room between spindle nose and workpiece, and tool length has to be planned on tall parts. Anything on the table, fixture included, must stay inside the Ø 990 mm (39 in) collision circle.

In load the machine sits between two fixed-table models. The C 250 GEN2 carries 1,100 kg (2,425 lb) on an 800 × 616 mm (31.5 × 24.3 in) fixed table and the C 400 GEN2 2,000 kg (4,409 lb) on a 1070 × 700 mm (42.1 × 27.6 in) fixed table, both at 35 m/min and with spindle lists that stop at 20,000 rpm. The C 42 U GEN2 carries its 1,400 kg (3,086 lb) on a table that swivels, moves at X 45 (60), Y 45 (60), Z 40 (60) m/min and adds 25,000 and 42,000 rpm to the same three lower speeds.

The tool magazine has 42 positions and is expandable to 160. Control is the Heidenhain TNC7 or the Siemens SINUMERIK ONE, where the two fixed-table models are listed with the TNC7 only. The C 42 U MT GEN2 is listed with the same travels, table size and load.

Strengths & Limitations

Strengths

1,400 kg (3,086 lb) on a swivelling rotary table of Ø 800 × 630 mm (Ø 31.5 × 24.8 in)
Workpieces up to Ø 800 × H 560 mm (Ø 31.5 × H 22 in) within a Ø 990 mm (39 in) collision circle
Higher load than the 1,100 kg (2,425 lb) fixed table of the C 250 GEN2, with full 5-axis movement
42 tool positions, expandable to 160
Heidenhain TNC7 or Siemens SINUMERIK ONE, and spindle options up to 42,000 rpm

Limitations

A part at the full 560 mm height leaves limited tool room under the max. 700 mm (27.6 in) table clearance
The C 400 GEN2 carries 2,000 kg (4,409 lb) on its fixed table, so the heaviest work is outside this machine
Z rapid is 40 m/min on the base figures, below the 45 m/min of X and Y
Z travel of 550 mm (21.7 in) is shorter than the 800 mm (31.5 in) of X and Y, which limits deep features on tall parts

Best For

Large 5-axis parts up to Ø 800 × H 560 mm (Ø 31.5 × H 22 in) Heavy workpieces and fixtures up to 1,400 kg (3,086 lb) that still need swivelling Long unattended runs with a magazine expanded towards 160 positions Mixed tool sizes, from 15,000 rpm general milling to 42,000 rpm small-tool finishing

Frequently Asked Questions

01 What is the maximum workpiece size and weight on the Hermle C 42 U GEN2?

Hermle lists Ø 800 × H 560 mm (Ø 31.5 × H 22 in) and 1,400 kg (3,086 lb). The swivelling rotary table measures Ø 800 × 630 mm (Ø 31.5 × 24.8 in), table clearance is max. 700 mm (27.6 in) and the collision circle is Ø 990 mm (39 in).

02 How does the C 42 U GEN2 differ from the C 400 GEN2?

The C 400 GEN2 has a 1070 × 700 mm (42.1 × 27.6 in) fixed table for 2,000 kg (4,409 lb), travels of 850 mm (33.5 in), 700 mm (27.6 in) and 500 mm (19.7 in), rapids of 35 m/min and three spindle speeds up to 20,000 rpm. The C 42 U GEN2 has a swivelling table for 1,400 kg (3,086 lb), 800 mm (31.5 in) of X and Y, and five spindle speeds up to 42,000 rpm.

03 Which controls and spindles are offered on the C 42 U GEN2?

The control is the Heidenhain TNC7 or the Siemens SINUMERIK ONE. Spindle options are 15,000, 16,000, 20,000, 25,000 and 42,000 rpm. For the ratings behind them, the C 42 technical data lists 31 kW and 194 Nm at 15,000 rpm and 35 kW with 17.5 Nm at 42,000 rpm.

04 How many tools can the C 42 U GEN2 hold?

The tool magazine has 42 positions and is expandable to 160. The C 42 technical data names the additional magazines as ZM 30, ZM 50, ZM 88 k, ZM 216 and ZM 528, so capacity is built up in stages according to how many jobs the machine has to keep tooled at once.
