The manufacture of exhaust manifolds and turbo housings on a machining centre presents particular challenges for tools and machines alike.
The machining process requires the highest levels of precision and wear resistance. The crucial machining operations for this process are: Milling the exhaust manifold surfaces and the relief grooves, counterboring the main bore and V-flange machining. In order to ensure a long tool life and stable processes, the focus is on designing the tools for maximum stability.
