Electric spindleIt is the core component of high-speed machining machines, and the accurate use and maintenance of electric spindles have a significant impact on the improvement of machining accuracy and the extension of service life of high-speed machining machines. Doing the following points well will inevitably improve the use and maintenance of the electric spindle.

① Do not clean the electric spindle with compressed air to prevent dust from entering the gap of the spindle and damaging its bearings;

② When cleaning the area around the electric spindle, even if the spindle is paused, the machine tool still needs to be powered on to ensure that the spindle bearings are maintained in the air curtain;

③ During the operation of the electric spindle, it is important to ensure that the cutting fluid is applied to the tool and not to the end of the spindle shaft;

④ It is necessary to regularly clean the tool handle installed on the electric spindle with a clean soft cloth to prevent dust from entering the spindle taper hole. Even when not in use, a tool handle should be kept on the spindle to maintain the taper hole of the spindle;

⑤ For new or unused electric spindles that have not been used for more than a month, it is important to ensure low-speed rolling during the initial operation, and it is best to perform idle preheating of the spindle;

⑥ In order to ensure the high precision of the electric spindle, only qualified tools with accurate dynamic balance can be used during high-speed operation. For high-precision cutting, it is best to preheat the electric spindle for 30 minutes to achieve thermal stability.

If the above points can be done well in the use and maintenance of the electric spindle, it can definitely achieve twice the result with half the effort. You may want to give it a try. Finally, it should be noted that the electric spindle cannot operate beyond its capacity under any circumstances, and you need to keep this in mind.
