The workpiece
Many important points must be observed in order to guarantee that every workpiece ismachined perfectly. For this reason, Hermle has been working on perfecting and optimising
the machining process for many years. This is the reason that the C 42 is now equipped with:- The largest working area relative to the installation area
- The largest swivelling range of workpieces in the working area
- Utilisation of the entire traverse range- A large collision circle between the table flanges

The workpiece dimension- Unlimited crane top loading to above the table centre-	When loading the crane the spindle moves to the magazine –this means the working area is completely clear and accessible-	Extensive automation solutions for optimum workpiece handling

Table variants
Hermle's NC swivelling rotary table has revolutionised the concept of 5-axis machining.
The C 42 also relies on 5-axis operation and takes full advantage of its advantages. These
include worm gears on the entry-level table and torque drive on the highly dynamic version.
All tables are manufactured exclusively and entirely at our plant in Gosheim.
Uncompromised perfection: This drive design accesses the gear on the table housing directly
and so completely eliminates shaft torsion. This is the only way to achieve the highest
precision for both one-sided and tandem drives.

20
21

02.5
Table variants
Made in Germany – made in Gosheim: The C 42 table variants stand for the highest quality
and optimum material usage from the cast housing to the installed gearbox and torque motors.
At our main plant in Gosheim, these tables are laying the foundations for the precision,accuracy and quality of the machined surfaces.

Technical data
High degree of freedom in working area
- Very high table load (up to 1400 kg with the highest accuracy)- No accumulation of chips on the table (swivel table)- Swivelling axis A and rotary axis C are located within the workpiece (U-shape)- Torsion prevented by tandem drive-	Wide spacing between results in a very large collision circle
in the working area
-	High swivelling range for undercuts

Worm table-	Generously dimensioned worm gear
- Low torsion attachment- Direct, absolute measuring system

Torque table-	High dynamics on the A and C axes
- No wear- Direct, absolute measuring system

Hermle's tables are equipped with cutting-edge drive technology for high dynamic during
5-axis machining as the slowest axis determines the speed of 5-axis simultaneous milling.
High-torque motors and the adapted gearbox can position loads of up to 1400 kg rapidly and,most importantly, with exceptional precision.

Drive technology- Centrical table load
- Drive directly on table housing = low torsion A axis
- Direct, absolute measuring system-	Good maintenance accessibility- A axis integrated in machine bed

One-sided drive- Mechanical drive on right oftable housing

Tandem drive- Mechanical tandem drive to left
and right of table housing

SpindlesThe C 42 can be equipped with two-piece or compact spindles. All spindles can be replaced
quickly and easily in case of failure.
With the different speed ranges and tool holding fixtures the spindles are suitable for a wide
variety of machining tasks. Like the tables, all spindles are manufactured exclusively andentirely at our plant in Gosheim.

Technical data
-	High-tech spindles for demanding milling processes- Slim-end spindle for machining deep cavities- Few projecting edges (prevention of collision)- Two-part spindle (faster, easier replacement)- Collision protection (collision sleeves) prevents damage in 50 % of collisions

Collision protection with collision inquiry
Each spindle has several collision sleeves which
compensate collision energy in the Z direction.

Automation . C 42
Everybody is talking about automation, but it’s much more than just a trend. We ourselves
have changed from being a machine manufacturer to a process provider because we believethat the decisive criterion for automated efficiency is integration of the entire environment.
In keeping with this philosophy, we are continuing what began with economical palletchanging and intelligent handling systems with highly advanced robot solutions. Therefore,
we have long been capable of converting machines into flexible manufacturing cells.

Automation . C 42
Our pallet changer is setting new standards for parallel setup in our highly dynamic machining
centres. A further increase in productivity allows for more adaptable storage systems.
Machining centres can be set up via pallet storage for production-oriented machine runs withminimum operator interference/without operator interference or for customer-specific runs
using a wide range of parts.
Furthermore, multiple machining centres can be linked to form a complete manufacturingsystem.

Precisionig hPrecision in every dimension: Hermle has a thorough understanding of the requirements for manufacturing high-precision
machining centres for processing smaller and larger workpieces of up to 2.5 t in weight. For this reason, "The Original" only uses
German machines for production and materials from European suppliers.
Furthermore, the entire machining production department is fully air conditioned and kept clean by a central chip disposal
system.
Hermle machining centres have also been thoroughly tested by intensive endurance tests and in manufacture-oriented
machining processes in our own machining manufacturing department. Our meticulous manufacturing processes allow Hermle
to set new precision standards which undercut those demanded by the DIN/ISO 10791 standard in every way.
At Hermle, we distinguish between positioning precision (accuracy with which a certain position within the working area can be
pinpointed on one axis) and geometric precision.
The latter is significant for the precision of the entire machine – it encompasses the following factors:- Positioning of linear and rotary axes
- Straightness and angular deviation of the linear axes
- Rectangularity and parallel alignment of all axes to one other- Concentricity and axial run-out of the table- Concentricity of the working spindle
The precision of Hermle machining centres originates during mechanical production and is not produced by subsequent
electronic compensation. This further improves the precision of the individual axes (precision package 1 and 2).

Precision levels

Improved precision
packages

Hermle standard:

Precision package 1(linear axes X, Y, and Z)

		
X-Y-Z: Pos. tolerance ≤ 8 µ- Straightness optimisation-	Geometry adjustment and optimisation- Straightness measurement- X, Y, Z positioning accuracy Pos. tolerance ≤ 5 µ-	Laser measurement according to VDI/DGQ 3441 or
ISO 230-2

		
A: Pos. tolerance ≤16"
		
C: Pos. tolerance ≤ 9"

Hermle improved precision*:		
X-Y-Z: Pos. tolerance ≤ 5 µ		
A: Pos. tolerance ≤10"
		
C: Pos. tolerance ≤ 6"

Precision package 2*(rotary axes A and C)- Table geometry- Axial run-out bearings- C axis position- Adjustment of complete table- Position of A and C axes relative to basic geometry-	Indexing precision A 10"-	Indexing precision C 6"-	Laser measurement according to VDI/DGQ 3441 or
ISO 230-2*To achieve improved precision, components must be
selected with care. Tolerances must also be taken into
account whilst the machine is still being constructed.
Hermle also recommends the HSK-A 63 tool holding
fixture, electr. heat compensation, an ICS recooling unit
and two-sided A axis drive.
Test and operating conditions are as follows: air
conditioned room (+20 ˚C, +/- 2 ˚C) and temperaturefluctuation of only 0.5 ˚C in one hour or max. 2 ˚C within
24 hours.

Energy efficiency
Both manufacturer and customer benefit from efficient production processes. Therefore, Hermle
has focused on integrated resource sustainability and energy efficiency for many years. We canrightly claim pioneer status in the Blue Competence initiative founded by the VDW (German
Machine Tool Builders Association).
From development to low-energy manufacturing (with a high level of in-house production) to theoperation of CNC machining centres - Hermle has stood for a principle of sustainable environmental protection combined with economic considerations for many years. Energy recovery isjust one of the advantages enjoyed by our customers.
