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 52 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- Unhindered crane loading from directly 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.
Also with the C 52, five axis operation is a key attribute, this capability is enhanced throughthe use of a torque drive. All tables are manufactured exclusively and entirely at our plant in
Gosheim.
Uncompromised perfection: this tandem drive design accesses the gearwheel on the tablehousing directly and so completely eliminates shaft torsion. This is the only way to achieve thehighest precision.

20
21

02.5
Table variants
Made in Germany – made in Gosheim: the C 52 table variants stand for the highest quality
and optimum material usage from the cast housing to the installed 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 2000 kg with the highest accuracy)-	No accumulation of chip 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 the A axis flanges results in very large collision circle-	High swivelling range for undercuts

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

Hermle tables are equipped with cutting edge drive technology for high dynamic performance
during 5 axis machining, as it is the slowest axis that determines the speed when milling in
5 axes. High-torque motors and the adapted gear can position loads of up to 2000 kg rapidly
and, most importantly, with exceptional precision.

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

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

SpindlesThe C 52 is equipped with 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 and entirely at our plant in Gosheim.

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 acomplete manufacturing system.

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 swarf 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 (on demand)

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 can rightly 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) tothe operation of CNC machining centres – Hermle has stood for a principle of sustainable environmental protection combined with economic considerations for many years. Energy recovery
is just one of the advantages enjoyed by our customers.

Efficientmanufacturing

Efficient
operation

We use energy efficient manufacturing methods not
because it is the current trend or because it is required ofus, but on principle. And we always have.

Our machining centres are energy efficient both during
their manufacture and during operation.

	Low energy component manufacture- Mineral casting technology-	Lightweight construction

Energy recovery has been standard
at Hermle for over 20 years
	High quality servo axes

Virtual machine optimisation /machine development
Reduction in the energy required for transport
through:-	High levels of in-house production- Just one production plant-	Locally sourced components
		 and materials-	No material tourism
	High-quality, high-efficiency components- Ball screws-	Guideways- Antifriction bearing etc.

	Ideal drive design for
the respective application
	Demand-based cooling technology
both for dimensioning andin application
	De-energize system:
Up to 80% less energy consumption
in stand-by mode
Very long machine service life
