Turbocharger
Exhaust gas turbochargers are used to boost the performance and efficiency of modern combustion engines. The compressed air supply increases efficiency while reducing emissions – a key aspect of current climate strategies. The most stringent requirements for coaxiality and circularity apply at speeds of up to 300,000 rpm. Particularly on the exhaust side (hot side), high-alloyed, abrasive workpiece materials pose extreme requirements for machining tool wear resistance. At high quantities, even small improvements in tool life for each tool lead to significant cost advantages in series production.
