HERMLE C 30 U – CNC 5-Axis Machining Center Year 2007
CNC 5-Axis Machining Center

HERMLE C30 MACHINING CENTER
Modified gantry design with the following special characteristics:

Design features:
– 3 axes in a tool and therefore dynamics independent from the workpiece
– Drives and guideways are outside of the working area – Compact structure, thus minimum space requirement – Optimized static and dynamic properties
– High running, positioning and long-term accuracy
– High dynamics during the machining process

Drives and guideways
– Optimum support of the main axes
– Y slide as traverse with 3 carriages on 3 staggered guideways
– Excellent guideway ratios of the traverse due to three point support and central drive
– Very rigid dynamic cross slide rest
– Mineral casting has excellent vibration dampening properties, very low thermal conductivity and is not hygroscopic
– Extremely high form and contour accuracy in all planes
– Optimum surface finish in combination with very narrow tolerances

Main spindle
– Collision protection with collision prompting at 10,000/18,000 rpm
(Hermle patent)
– Water-cooled AC spindle motors as hollow shaft motors

Tool change
– Automatic tool change with the pick-up method – Integrated in the machine body
– Protected outside the working area

Electronics
– Frequency-based recovery of the braking energy into the mains – Absolute measurement systems
– Switch cabinet with cooling unit
– Digital drives
Working area Traverses X-Y-Z
Direct position measuring system Resolution
Positional tolerance
Tp in X-Y-Z axes according to VDI/DGQ 3441
To be able to maintain the indicated accuracy over the entire duration of use, the
ambient temperature should be continuously 20°C +/-1°.
Line filter
Leveling pads (height adjustable)

Adapter for oil mist extractor
Switch cabinet cooling with temperature adjustment
Coloring
Machine bed in unpainted mineral casting, Cast parts in RAL 7005 mouse grey, Enclosure sheets made of stainless steel and painted sheet metal in RAL 7035 light grey, with lettering on the front and on the side and vertical strips in flame red RAL 3000
Connection values
Mains connection 400 V/50 Hz Power consumption max. 43 kVA Compressed air 6 bar Note: The compressed air must be clean, dry and free of oil!
Special voltages and frequencies on request! Connection conditions:
The HERMLE milling machines are equipped with a frequency-controlled converter system. They may only be connected to grounded mains
TN-S and TN-C (VDE 0100 Part 300) at a nominal voltage
3 AC 400 V.
In case of other mains voltages, an autotransformer can be connected upstream. If the network structure deviates from the previously described TN-S and TN-C, an isolating transformer with star point
on the secondary side must be provided.
System short-circuit capacity:
The converters are adapted to sine current operation. The
system short-circuit capacity (SK network) at the connecting point of the machine must conform to the following specifications:
C 30 equipped with Heidenhain control iTNC 530
Minimum short-circuit capacity 2.15 MVA

Chip to chip time according to VDI 2852 standard version
Chip to chip time according to VDI 2852 dynamic version
In connection with an additional magazine, the above tool
diameter is reduced to 80 mm.
During every tool change the tool cone is cleaned automatically by compressed air.
Balancing qualities
It is mandatory that tools and tool holding fixtures are balanced according to latest state of the art technology.
The balancing qualities (according to DIN/ISO 1940) that are necessary and reasonable need to be determined from case to case, since they are influenced by the spindle speed and the tool weight.

Additional magazin 87 pockets

with vacant adjacent pockets 125mm
max. tool length 300mm
max. tool weight 8kg.
max.magazine load 348kg.
