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 250 is a 5-axis machining centre with 600 mm, 550 mm and 450 mm of X, Y and Z travel, built in three table versions: a swivelling rotary table of Ø 320 mm or Ø 450 x 360 mm, or a rigid clamping table of 800 x 616 mm. The table chosen changes what the machine is. The swivelling rotary table carries 300 kg and the workpiece can be up to Ø 450 mm and 355 mm high, while the rigid clamping table carries 1,100 kg.

All three linear axes share the same figures: 35 m/min rapid traverse, 6 m/s² acceleration and 5,000 N of feed force. The A-axis swivels +/- 115° and the C-axis turns at 40 rpm, a rate for positioning and contouring. Vertical table clearance is 550 mm and the collision circle is Ø 770 mm with the A-axis in the 0° position.

Hermle lists three spindles. With SK 40 the speed is 15,000 rpm; with HSK A 63 it is 16,000 rpm or 20,000 rpm. The 15,000 and 16,000 rpm spindles are rated 20 kW and 173 Nm, and the 20,000 rpm spindle 42 kW and 148 Nm, all at 20% c.d.f. The fast spindle therefore has about twice the power but less torque, which favours high removal rates at speed over slow cuts with large tools.

The magazine has 30 pockets as standard, with additional magazines ZM 30, ZM 50, ZM 88 k and ZM 216 available. A tool may be 300 mm long, Ø 80 mm (Ø 125 mm with corresponding adjacent pocket allocation) and 8 kg. The magazine as a whole is limited to 120 kg, so a full set cannot all be at the weight limit. Chip-to-chip time is approx. 6 s.

Positioning uncertainty is ≤ 0.006 mm to ISO 230-2 in X, Y and Z. The machine weighs approx. 8.2 t, connects to 400 V / 50 Hz or 460 V / 60 Hz with up to 43 kVA, and runs the Heidenhain TNC7.

Strengths & Limitations

Strengths

Three table versions: swivelling rotary table Ø 320 mm or Ø 450 x 360 mm, or a rigid clamping table of 800 x 616 mm rated for 1,100 kg
Equal axis figures in X, Y and Z: 35 m/min rapid, 6 m/s² acceleration and 5,000 N feed force
Spindle choice between 20 kW with 173 Nm at 15,000 / 16,000 rpm and 42 kW with 148 Nm at 20,000 rpm (20% c.d.f.)
Positioning uncertainty of ≤ 0.006 mm to ISO 230-2 in X, Y and Z
30 pockets as standard, extendable with ZM 30, ZM 50, ZM 88 k or ZM 216 additional magazines

Limitations

The swivelling rotary table carries 300 kg; the 1,100 kg rating applies only to the rigid clamping table
Spindle speed stops at 20,000 rpm, with no faster option on the list
Tools are limited to 8 kg each and 120 kg for the whole magazine, so heavy tools reduce how many can be loaded
Chip-to-chip time of approx. 6 s adds up on parts with many short operations
Ø 125 mm tools need the adjacent pockets allocated accordingly; otherwise the limit is Ø 80 mm

Best For

5-axis parts up to Ø 450 mm, 355 mm high and 300 kg on the swivelling rotary table Heavier plate and fixture work up to 1,100 kg on the rigid clamping table of 800 x 616 mm Aluminium roughing and finishing with the 42 kW, 20,000 rpm HSK A 63 spindle Steel work that needs the 173 Nm of the 15,000 or 16,000 rpm spindles Shops with a 43 kVA connection and room for a machine of approx. 8.2 t

Frequently Asked Questions

01 Which tables can the Hermle C 250 be ordered with?

Hermle lists a swivelling rotary table of Ø 320 mm or Ø 450 x 360 mm and a rigid clamping table of 800 x 616 mm. Table load capacity is 300 kg for the swivelling rotary table and 1,100 kg for the rigid clamping table. The swivelling range of the A-axis is +/- 115° and the C-axis speed is 40 rpm.

02 What spindles are available on the C 250?

Three. An SK 40 spindle at 15,000 rpm and an HSK A 63 spindle at 16,000 rpm are both rated 20 kW and 173 Nm. An HSK A 63 spindle at 20,000 rpm is rated 42 kW and 148 Nm. All ratings are at 20% c.d.f., a short-duty figure, so continuous cutting power will be lower.

03 What are the tool limits of the C 250 magazine?

The standard magazine has 30 pockets. Maximum tool length is 300 mm, maximum diameter is Ø 80 mm, or Ø 125 mm with corresponding adjacent pocket allocation, and maximum tool weight is 8 kg. The total magazine load is 120 kg. Additional magazines ZM 30, ZM 50, ZM 88 k and ZM 216 are listed.

04 What does the C 250 need for installation?

The machine weighs approx. 8.2 t. The power supply is 400 V / 50 Hz or 460 V / 60 Hz, with a connected load of up to 43 kVA. Check floor loading and the route into the building against that weight before delivery.

05 How accurate and how fast are the linear axes of the C 250?

Hermle states a positioning uncertainty of ≤ 0.006 mm to ISO 230-2 for X, Y and Z. Rapid traverse is 35 - 35 - 35 m/min, linear acceleration is 6 m/s² and the feed force is 5,000 N in each axis.
