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 RS pairs a small 5-axis machining centre with an integrated robot system and pallet storage for 10-20 pallets. Travels are 350 mm (13.8 in) in X, 440 mm (17.3 in) in Y and 330 mm (13.0 in) in Z over a 320 mm (12.6 in) table. The point of the package is unattended running of small parts, not a large working envelope.

Everything on the table has to stay inside the 100 kg (220 lb) load capacity, pallet and fixture included, so the cell suits parts that are light as well as small. The A-axis swivels +/- 115 degrees (230 degrees total) and the C-axis turns 360 degrees continuously, which lets each pallet be machined on five sides without anyone re-clamping it.

The listed spindle is HSK-A63 at 15,000 rpm with a 10 kW (13.4 hp) motor as standard, and speeds up to 42,000 rpm are optional. That motor rating is for finishing and light roughing. The magazine has 30 positions, expandable to 55, and the listed chip-to-chip time is 2.8 seconds. With several different jobs queued on the pallets, add up the tools every job needs, sister tools included, before deciding whether 30 positions are enough.

The listed figures give 5,500 kg (12,125 lb) for the machine and approximately 5 m² (54 ft²) of floor space including the robot system. The base is mineral cast, the control is the Heidenhain TNC 640 and the supply is 400V, 3-phase, 50/60 Hz. Positioning accuracy is listed at +/- 0.005 mm (0.0002 in) and repeatability at +/- 0.003 mm (0.00012 in).

Strengths & Limitations

Strengths

Integrated robot system with pallet storage for 10-20 pallets, so a queue of small parts runs without an operator loading each one
A-axis swivel of +/- 115 degrees (230 degrees total) and a continuous C-axis for five-sided machining of every pallet
Listed chip-to-chip time of 2.8 seconds, which counts on small parts with many short operations
Spindle options up to 42,000 rpm for small tools; 15,000 rpm with HSK-A63 is standard
Approximately 5 m² (54 ft²) of floor space including the robot system

Limitations

Table load capacity is 100 kg (220 lb), and pallet, fixture and part all count towards it
Travels of 350 mm (13.8 in), 440 mm (17.3 in) and 330 mm (13.0 in) over a 320 mm (12.6 in) table confine it to small parts
The standard spindle motor is 10 kW (13.4 hp), a finishing and light-roughing rating
30 positions as standard can run short when the pallets carry different jobs; the magazine is expandable to 55

Best For

Unattended production of small 5-axis parts from 10-20 pallets Parts that stay within 100 kg (220 lb) including pallet and fixture Small-tool finishing with the optional spindles up to 42,000 rpm Small precision components that fit a 320 mm (12.6 in) table

Frequently Asked Questions

01 What automation does the Hermle C 12 U RS include?

The listed figures describe an integrated robot system with pallet storage for 10-20 pallets. The floor space is given as approximately 5 m² (54 ft²) including the robot system, so the automation is part of the machine's own footprint and not a separate cell placed beside it.

02 How large a part can the C 12 U RS machine?

Travels are 350 mm (13.8 in) in X, 440 mm (17.3 in) in Y and 330 mm (13.0 in) in Z, the table diameter is 320 mm (12.6 in) and the table load capacity is 100 kg (220 lb). On a palletised machine the pallet and fixture are part of that load, so the usable part weight is lower.

03 What spindle and tool magazine does the C 12 U RS have?

The standard spindle is listed at 15,000 rpm with a 10 kW (13.4 hp) motor and an HSK-A63 taper, and spindles up to 42,000 rpm are optional. The tool magazine has 30 positions and is expandable to 55. The chip-to-chip time is listed as 2.8 seconds.

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

The linear travels and the 100 kg (220 lb) table load are the same on both. The C 12 U GEN2 is listed with the Heidenhain TNC7 and rapids of 30 (50) m/min. The listed figures for the C 12 U RS show the Heidenhain TNC 640 and 35 m/min (1,378 ipm), and add the integrated robot system with storage for 10-20 pallets.
