Siberian conditions: We built a system for the assembly and leak testing of cylinder heads for a large manufacturer of trucks, buses and diesel engines from Russia. This even includes a liquid nitrogen container in which the components are super cooled for pressing in.
Precise assembly under extreme conditions is crucial for components that have been precision-machined down to the micrometer, such as valve guides or valve seat rings. Due to the extreme supercooling of the components using nitrogen, these are shrunk together to make it possible to press them into the openings provided. This is a high-precision process that has to be implemented in a very short time.
Precision and speed are equally important when working with extremely supercooled components.
Precise cycle times and accurate matching of processes present special challenges here.
The integration of manual processes with semi-automated and fully-automated procedures in assembly and material flow requires perfectly coordinated timing, which satisfies not just the needs of the manual work, but also the requirements of the special assembly conditions. In this project, we coordinated all steps down to the last detail.
We would be happy to advise you on comparable projects and answer any questions regarding our reference cases.
