Urbochargers are important components to minimize the petrol consumption of modern gasoline engines. The temperature in the turbocharger housings can reach until1.050 °C. Due to this reason, high heat resistant stainless steel, like the material DIN1.4848 with a high quantity of nickel (up to 25 %) and chrome (up to 20 %) is used in this application. During metal cutting operations the temperature at the cutting edge will increase due to the high quantity of nickel and the abrasive wear will be created by the chrome carbides within the cast material. The material hardness can increase by the machining process. Drilling and threading are one of the most critical machining operations in this material, because a huge frication area exists between the material and the tool. This provokes a high friction and the possibility of built-up-edge at the cutting edge which provides the rapid wear of the tool. In this part of the development project the tool life of different threading tools was analyzed. Taps in HSS-Co-PM and solid carbide were available for the tool life tests. The possibility to use the cold forming technology for threading was also analyzed. The strength of the internal threads was tested with pull out tests according DIN 898-2.
