The transformation of mobility is in full swing. And so the focus has turned to developing new parts. However, it’s clear that motors with turbocharger will continue to be built for some time. Therefore, the machining business continues to strive for tool solutions with higher cutting values, longer tool life and thus lower costs per part.
The turbocharger housing is a particularly worthwhile part to optimise in manufacturing as its machining involves a great deal of wear and tear. While the tool life for other car parts like cylinder crankcases, stub axles or brake calipers are in the thousands of parts, on average 30 to 140 turbocharger parts can be manufactured by a tool, depending on the machining length and workpiece material. Typically, turbochargers are made with the workpiece materials 1.4847, 1.4848, 1.4849 or 1.4837, which are heat-resistant stainless cast steels – a material that is extremely abrasive.
