Tooling solutions for machining cylinder heads in ISO K and ISO N materials
The cylinder head conveys air and fuel to the combustion chamber and serves as a cover for the cylinders as it sits on top of the cylinder block. It is also the housing for several different components, such as valves, spark plugs and fuel injectors.
Besides the cylinder block, the cylinder head process is the one involving the most machines in automotive component production. There are several complex processes and tight tolerances involved, especially in the valve seat and guide and in the deck face. As the cylinder head is an essential part of the engine, quality is crucial for the performance of the vehicle. Cost-efficient manufacturing is also of great importance for these types of components.
Besides our extensive offer, Sandvik Coromant also has dedicated products and engineered solutions that fully support overcoming the challenges presented by manufacturing these components.
