Grinding Operation - an overview | ScienceDirect Topics
A 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 ...

the operation of the device it-self. As an object (or target) makes contact with the operator of the switch, it eventually moves the actuator to the "limit" where the elec-trical contacts change state. Through this mechanical action, electrical contacts are either opened (in a normally closed circuit) or closed (in a normally open circuit).
CNC Milling - a Complete Guide to Understand the Process
Again, the name of a vertical mill is pretty self-evident when looking at the image above. As the positioning of the tool axis is vertical, it is better suited for end milling. There are a few differences between horizontal and vertical milling machines. But the main components are still similar. The machine head is at the end of a ram.
