Succinct designation, great performance

The rather succinct designation C50 is worlds away from the technical possibilities offered by this machine.
The latest accomplishment of Spiess Motorenbau GmbH is built for the future. The Hermle C50 guarantees highly dynamic, simultaneous five-axis processing in the highest quality. Several axes are processed at once and thus offer time-saving, flexible production possibilities.

The C50 can also handle large workpieces. up to 2,000 kilograms, with the highest precision. And it is seldom necessary to re-span the workpieces, since the machine's swivel range is laid out to be sufficiently great.
The C50 offers great advantages, especially for making prototypes and engines, because it offers ideal conditions for channel processing, for instance, where work can be done from many different sides and angles.

Yet more advantages are offered by the special cooling agent feed, which works at up to 80 bars of pressure. The better cooling effect achieved by the high pressure saves wear and tear on tools and reduces the adverse effect of heat on the material characteristics.

The air-conditioned, encapsulated interior of the Hermle C50 hat several positive effects. For one thing, it helps the environment, since it runs on a closed system that cannot allow liquids or dust to escape.
For another, it guarantees to keep the temperature as constant as possible, to lower the material shrinkage and facilitate keeping to prescribed tolerances.

Changeover and machining times can be reduced yet more by using the expanded tool changer that holds100 tools and the laser-controlled equalization of tool wear ensures ongoing quality control.

The C50 will make your production ready for the challenges of the future.

Construction Design of completely new engines or the enhancement of existing power units –inventive spirit, courage, extensive team work and our huge wealth of represent the basis for innovative results.
Manufacturing Precision components or the refinement of existing components, single copy or small-batch series, solid material or cast material – a diversified service range thanks to an ambitious mix of know-how and new developments.
Quality management Out there on the racetrack, the smallest mistake can be crucial. Therefore, special emphasis is placed to a gapless and absolutely precise quality control. No part will be installed without having been subjected to an extremely strict examination.
Engine manufacturing The engines are individual custom products and are assembled in the heart of the company by a highly qualified team. Here, quality instead of quantity represents the yardstick.
Test bench Here, the process represented by development and design, production and manufacturing comes full circle. On the test rigs, the components or the entire project have to definitively demonstrate if they meet the highest standards.
