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 400 is a 5-axis machining centre with 850 mm (33.5 in) of X, 700 mm (27.6 in) of Y and 500 mm (19.7 in) of Z travel. The listed figures cover two table versions: a trunnion with a Ø 650 mm clamping surface that carries 800 kg (1,764 lb), and a rigid table of 1,070 x 700 mm that carries 2,000 kg (4,409 lb).

On the trunnion the largest workpiece is Ø 650 x 500 mm (Ø 25.6 x 19.7 in), inside a collision circle of Ø 885 mm and under a vertical clearance of 625 mm max. The A-axis is listed from -115° to +100° and the C-axis as 360° continuous. X travel is well beyond the workpiece diameter, which gives the spindle room to work round a tilted part instead of running out of stroke at its edge.

The spindle is HSK-A63 at 15,000 RPM with 20 kW (27 hp) continuous and 173 Nm (128 ft-lb); 18,000 or 20,000 RPM is optional. The magazine holds 38 tools, or up to 126 with ZM modules, and chip-to-chip time is 6 sec. Rapids are 35 m/min (1,378 ipm) in X, Y and Z.

The machine weighs 12,500 kg (27,558 lb) and measures 3,520 x 4,820 x 3,080 mm (138.6 x 189.8 x 121.3 in) W x D x H. Listed positioning accuracy is ±0.005 mm (±0.0002 in) and repeatability ±0.003 mm (±0.0001 in). The control row names the Heidenhain TNC7 for GEN2 machines and the Heidenhain TNC 640 for earlier ones, so establish which generation a particular machine belongs to.

Strengths & Limitations

Strengths

Two table versions: 800 kg (1,764 lb) on the trunnion or 2,000 kg (4,409 lb) on the rigid table of 1,070 x 700 mm
850 mm (33.5 in) of X travel around a Ø 650 mm clamping surface
173 Nm (128 ft-lb) and 20 kW (27 hp) continuous at 15,000 RPM with HSK-A63
38 tools as listed, extendable up to 126 with ZM modules
Listed positioning accuracy of ±0.005 mm (±0.0002 in)

Limitations

The trunnion carries 800 kg (1,764 lb), well under the 2,000 kg (4,409 lb) of the rigid table
Chip-to-chip time of 6 sec is slow for parts with many short operations
The A-axis range of -115° to +100° is not symmetric
The 18,000 or 20,000 RPM spindles and the ZM modules are options
A weight of 12,500 kg (27,558 lb) and a height of 3,080 mm (121.3 in) need checking against floor and door limits

Best For

5-axis parts up to Ø 650 x 500 mm (Ø 25.6 x 19.7 in) and 800 kg (1,764 lb) Heavy work clamped flat, up to 2,000 kg (4,409 lb) on the rigid table Steel and cast-iron milling that uses the 173 Nm (128 ft-lb) spindle Shops that can house a 3,520 x 4,820 mm machine

Frequently Asked Questions

01 What is the difference between the trunnion and rigid table on the Hermle C 400?

The listed figures give a Ø 650 mm clamping surface and 800 kg (1,764 lb) for the trunnion, and 1,070 x 700 mm and 2,000 kg (4,409 lb) for the rigid table. The trunnion adds the A-axis, listed from -115° to +100°, and a continuous 360° C-axis; the rigid table trades those for load.

02 What spindle is listed for the C 400?

An HSK-A63 spindle at 15,000 RPM with 20 kW (27 hp) continuous and 173 Nm (128 ft-lb) of torque. Spindles at 18,000 or 20,000 RPM are optional. The C 400 GEN2 is listed with 15,000 / 16,000 / 20,000 rpm options, so check which spindle a particular machine has.

03 How much space does the C 400 need?

The listed footprint is 3,520 x 4,820 x 3,080 mm (138.6 x 189.8 x 121.3 in) as width, depth and height, and the machine weighs 12,500 kg (27,558 lb). Allow for access around the machine on top of that footprint.

04 How many tools does the C 400 hold?

The listed capacity is 38 tools, or up to 126 with ZM modules, and the chip-to-chip time is 6 sec. The spindle taper is HSK-A63. If a job needs more than 38 tools, confirm that the machine in question has the additional modules fitted.
