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 is a 5-axis machining centre with 800 mm of X, 800 mm of Y and 550 mm of Z travel, taking workpieces up to Ø 800 mm and 560 mm high. Hermle offers it with five spindles and four tables, and most of what a buyer has to decide sits in those two lists.

Table load depends on the table and on its drive. The Ø 440 mm swivelling rotary table carries 450 kg. The Ø 800 x 630 mm table carries 850 kg with worm drive and 1,400 kg with the torque tandem drive, and the rigid clamping table of 1,050 x 805 mm carries 2,000 kg. An MT variant with a Ø 750 mm table is also listed. The A-axis swivels +/- 130°, vertical table clearance is 700 mm and the collision circle is Ø 990 mm with the A-axis at 0°.

Spindle power is quoted at 20% c.d.f. The 15,000 rpm spindle gives 31 kW and 194 Nm, the highest torque on the list. The 16,000 rpm spindle gives 20 kW and 173 Nm, the 20,000 rpm spindle 42 kW and 148 Nm, and the 25,000 rpm spindle 31 kW and 98 Nm; all four use HSK A 63. The 42,000 rpm spindle uses HSK E 40 and gives 35 kW with 17.5 Nm. Choosing it changes the tooling too: tool weight falls from 8 kg to 2.5 kg and magazine load from 168 kg to 105 kg.

Rapids are 45 - 45 - 40 m/min in X, Y and Z, or 60 - 60 - 60 m/min in the dynamic version, with 8,500 N of feed force. The magazine has 42 pockets as standard and takes ZM 30, ZM 50, ZM 88 k, ZM 216 or ZM 528 additional magazines. Tools may be 350 mm long and Ø 80 mm, or Ø 125 mm with corresponding adjacent pocket allocation, and chip-to-chip time is approx. 4.5 s.

Positioning uncertainty is ≤ 0.006 mm to ISO 230-2. The machine weighs approx. 13.5 t and is controlled by the Heidenhain TNC7 or the Siemens SINUMERIK ONE.

Strengths & Limitations

Strengths

Five spindles from 15,000 to 42,000 rpm, including 31 kW with 194 Nm at 15,000 rpm and 42 kW at 20,000 rpm (20% c.d.f.)
Table load up to 1,400 kg on the Ø 800 x 630 mm swivelling rotary table with torque tandem drive
Dynamic version with 60 - 60 - 60 m/min rapids in place of 45 - 45 - 40 m/min
42 pockets as standard, extendable up to the ZM 528 additional magazine
8,500 N of feed force in X, Y and Z and a positioning uncertainty of ≤ 0.006 mm to ISO 230-2
Rigid clamping table of 1,050 x 805 mm rated for 2,000 kg as an alternative to the swivelling tables

Limitations

With worm drive the Ø 800 x 630 mm table carries 850 kg, well short of the 1,400 kg torque tandem figure
The 42,000 rpm spindle means HSK E 40 tooling limited to 2.5 kg per tool and 105 kg in the magazine
The 16,000 rpm spindle is rated 20 kW, the lowest power on the list
Base Z rapid is 40 m/min; the 60 m/min figure belongs to the dynamic version
At approx. 13.5 t with a connection of up to 57 kVA, or 61 kVA for the C 42 MT, the machine needs a prepared site

Best For

5-axis workpieces up to Ø 800 mm and 560 mm high Heavy parts up to 1,400 kg on the torque tandem table or 2,000 kg on the rigid clamping table High-torque milling with the 194 Nm, 15,000 rpm HSK A 63 spindle High-power aluminium cutting with the 42 kW, 20,000 rpm spindle Fine finishing with small HSK E 40 tools at 42,000 rpm

Frequently Asked Questions

01 Which spindle should I choose on the Hermle C 42?

It depends on tool size. The 15,000 rpm HSK A 63 spindle has the most torque, 194 Nm with 31 kW. The 20,000 rpm spindle has the most power, 42 kW with 148 Nm. The 25,000 rpm spindle gives 31 kW and 98 Nm, and the 42,000 rpm HSK E 40 spindle 35 kW and 17.5 Nm for small tools. Power figures are at 20% c.d.f.

02 How much weight can the C 42 table carry?

Hermle lists 450 kg for the Ø 440 mm swivelling rotary table, 850 kg for the Ø 800 x 630 mm table with worm drive, 1,400 kg for the same table with torque tandem drive and 2,000 kg for the rigid clamping table of 1,050 x 805 mm. State the table and the drive when asking for a quotation.

03 What are the tool limits on the C 42?

Maximum tool length is 350 mm and maximum diameter is Ø 80 mm, or Ø 125 mm with corresponding adjacent pocket allocation. Tool weight is limited to 8 kg with HSK A/T 63 and 2.5 kg with HSK E 40. The magazine load is 168 kg or 105 kg respectively, and the standard magazine has 42 pockets.

04 What is the difference between the standard and dynamic C 42?

Rapid traverse is 45 - 45 - 40 m/min in X, Y and Z as standard and 60 - 60 - 60 m/min in the dynamic version. Linear acceleration is listed as 6 (10) m/s². The feed force is 8,500 N in each axis in both cases.

05 What power supply does the C 42 need?

400 V / 50 Hz or 460 V / 60 Hz. The connected load is up to 57 kVA for the C 42 and up to 61 kVA for the C 42 MT. The machine weighs approx. 13.5 t, so foundation and transport access should be checked along with the electrical supply.
