Tips: How to Maintain a Spindle Motor?
- The high-speed spindle motor is the core component of the machining machine tool. The correct use and maintenance of the spindle motor has an extremely important impact on the improvement of the machining accuracy of the CNC machine tool and the extension of the service life.
- Do not use compressed air to clean the spindle motor to avoid bringing dust into the spindle gap and damage the spindle bearing.
- When cleaning the area around the spindle motor, although the spindle is stopped, the machine tool should be powered on, and the spindle bearing should be protected by air curtain.
- When the spindle motor is in use, pay attention that the cutting fluid should be hit on the cutting tool, not on the end of the spindle.
- For the tool mounted on the spindle motor, the handle part must be cleaned regularly with a clean soft cloth to avoid bringing dust into the spindle taper hole. Even when not in use, a tool holder should be reserved on the spindle to protect the spindle taper hole.
- For a new spindle motor or a spindle motor that has not been used for more than one month, it must be ensured to rotate at a low speed when it first starts to work, and it is best to perform the spindle preheating and idling.
- In order to ensure the high precision of the spindle motor, only accurate dynamic balance up-to-standard tools can be used during high-speed operation. It is best to preheat the spindle motor for 30 minutes to reach a thermally stable state for high-precision cutting.
