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 12 U GEN2 is a small 5-axis machining centre: a traverse path of 350 x 440 x 330 mm, a ø 320 mm swivelling rotary table and a table load of 100 kg (220 lb). Hermle lists the largest workpiece as Ø 320 × H 265 mm (Ø 12.6 × H 10.4 in). That diameter equals the table, so parts sit within the table face and the machine stays a tool for small components.

For a machine of this size the spindle list is long: 15,000, 16,000, 20,000, 25,000, 30,000 or 42,000 rpm. Small parts usually mean small cutters, and the upper end of that list is what lets them run at a sensible surface speed. Rapid traverse is given as 30 (50) m/min. Read that as 30 m/min for the base machine with 50 m/min as the bracketed higher figure, and confirm which one a quotation includes.

Table clearance is max. 430 mm (16.9 in) and the collision circle is Ø 610 mm (24 in). A part at the full 265 mm height takes a large share of that clearance, so short tool assemblies and low fixtures matter on tall workpieces. Z travel is 330 mm (13 in).

The base is mineral cast, the control is the Heidenhain TNC7 and the supply is 400V, 3-phase, 50/60 Hz. The next size up, the C 22 U GEN2, keeps the ø 320 mm table and the 330 mm (13 in) of Z but has 450 mm (17.7 in) of X, 600 mm (23.6 in) of Y and a 300 kg (661 lb) table load, and adds the Siemens SINUMERIK ONE as a second control choice.

Strengths & Limitations

Strengths

Six listed spindle speeds up to 42,000 rpm, a wide choice for small-tool work
Workpieces up to Ø 320 × H 265 mm (Ø 12.6 × H 10.4 in) on a ø 320 mm swivelling rotary table
Table clearance of max. 430 mm (16.9 in) within a collision circle of Ø 610 mm (24 in)
Mineral cast base and the Heidenhain TNC7 control

Limitations

Table load is 100 kg (220 lb); the C 22 U GEN2 carries 300 kg (661 lb) on the same ø 320 mm table
Travels of 350 mm (13.8 in) in X and 440 mm (17.3 in) in Y rule out anything beyond small parts
Workpiece height stops at 265 mm, and tall parts leave limited tool room under the max. 430 mm (16.9 in) clearance
The Heidenhain TNC7 is the only control listed, where the C 22 U GEN2 also offers the Siemens SINUMERIK ONE

Best For

Small 5-axis components up to Ø 320 × H 265 mm (Ø 12.6 × H 10.4 in) Light parts and fixtures within 100 kg (220 lb) Fine detail work with small cutters at 30,000 or 42,000 rpm Shops standardised on the Heidenhain TNC7

Frequently Asked Questions

01 What is the largest part the Hermle C 12 U GEN2 can machine?

Hermle lists the maximum workpiece as Ø 320 × H 265 mm (Ø 12.6 × H 10.4 in) with a table load of 100 kg (220 lb). The traverse path is 350 x 440 x 330 mm, table clearance is max. 430 mm (16.9 in) and the collision circle is Ø 610 mm (24 in).

02 Which spindle speeds can be ordered on the C 12 U GEN2?

Six: 15,000, 16,000, 20,000, 25,000, 30,000 and 42,000 rpm. The listed data for this model gives no power, torque or taper for them, so ask Hermle for the rating of each spindle and decide by the tools the parts need.

03 What do the rapid traverse figures 30 (50) m/min mean?

Hermle lists rapid traverse for the C 12 U GEN2 as 30 (50) m/min. The C 12 is listed with 30 m/min (1,181 ipm) standard and 50 m/min (1,969 ipm) optional, which matches a reading of 30 m/min as the base rate and 50 m/min as the faster version. Confirm it for the machine being quoted.

04 How does the C 12 U GEN2 differ from the C 22 U GEN2?

Both have a ø 320 mm table, 330 mm (13 in) of Z and the same six spindle speeds. The C 22 U GEN2 has 450 mm (17.7 in) of X and 600 mm (23.6 in) of Y against 350 mm (13.8 in) and 440 mm (17.3 in), carries 300 kg (661 lb) against 100 kg (220 lb), and is offered with the Heidenhain TNC7 or the Siemens SINUMERIK ONE.
