DetailsEMUGE-FRANKEN was the first company to introduce Circle Segment end mills for 5-Axis milling. This family of tool designs constitute a new tool class that enable machining with a larger tool path distance during pre-finishing and finishing operations. These tools are primarily used in mold-making as well as in the production of tire molds, turbine blades, impeller blades or
DetailsA mill ready to start a grinding operation could be around 150 t in dead weight. Thus, the initial torque on the mill shaft is very high and an electric drive motor and drive is designed to cope with it. Figure 8.11 illustrates a typical change in torque with increasing speed of motor. It can be seen that the peak torque of 140% of the running ...
