Construction

S. Spiess Motorenbau GmbH designs, develops, constructs and produces everything from the component to the entire engine. And we also specialise in the enhancement of existing engines. The design and development are performed according to our own guidelines or the individual specifications of our customers. Our combination of ingenuity, courage, extensive team work and outstanding experience makes for innovative results.

Multifaceted competence

helps finding new solutions. The use of Siemens NX as an integrated system which all departments are working with allows for combining, updating and accessing experiences at any time.

The construction department uses the latest, most sophisticated 3D-CAD workstations to design, develop, construct and document all components of the engines. The toughness of the components is examined by means of an FEM analysis in conjunction with the construction process. It goes without saying that the consistent data exchange with the respective customer represents an integral part of every job. This is made possible by all the established interfaces that allow – in addition – for a secure communication.

The CAM module integrated in the CAx system helps to optimise the entire work processes from the first planning to the completed work piece. Post processors with up to five axes do not only allow for the pure output formatting in different NC languages, but also ensure the calculational identification of the tool’s axial rotation and its angle to the work piece.

Many years of competence in:

  • 3D design
  • CAD construction - ENX data exchange
  • CAD design - System UG
  • FEM simulation
  • FEM analysis

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.
