The mechanical electrical spindle of engraving milling machine is different due to the internal structure of different manufacturers, but the basic principle is that the front rear groups of bearing support, but the bearing size is different, the material may be different. But the principle of reducing friction between bearing bearing itself is consistent. Even if the friction of the bearing is small when the spindle is rotating, a slight friction will increase the temperature at high speed. The temperature increases with the increase of speed working time.

At this point, the heat generated by the bearing will also be transferred to the spindle itself, causing the spindle temperature to rise. Therefore, we can know that the spindle temperature mainly comes the bearing, the temperature rise of the bearing depends on its internal friction coefficient. When the bearing is damaged, the friction coefficient increases the temperature rises. Then the spindle needs to be replaced. Of course, the spindle temperature rise, in addition to this internal problem, there may also be external factors.

This paper briefly introduces the operation of large-scale high-speed engraving milling machine

1. Check the temperature quantity of coolant in the coolant tank of high-speed engraving machine. If the quantity is insufficient, it needs to be replenished in time. In addition, make sure that the coolant is frozen circulates normally.

2. When installing the bayonet, people need to put the handle into the relevant card, the length is generally greater than 18 mm, otherwise it is easy to loosen. In addition, people need to check the cards carefully for dirt before installing the bayonet. If there is dirt, you need to clean it up to make sure the installation is reliable easy to have problems.

3. The general card material needs to be firmly fixed easy to vibrate, otherwise it is easy to cause accidents of different degrees. It is forbidden to use Yiming engraving machine to carve mill at the place the material is suspended.

4. In the process of machining, people use metal materials, so it is necessary to use cutting blood to ensure the reduction of tool wear.

5. In the process of engraving milling, people should observe the cutting surface closely, otherwise it is easy to cause cutting into the eyes cause unnecessary safety problems. In general, people should turn off the high-speed engraving milling machine to ensure that it is no longer running.
