Daily maintenance of mechanical spindle
Mechanical spindle is the core component of high-speed machining machine tool. The correct use and maintenance of mechanical spindle has a very important influe
Mechanical spindle is the core component of high-speed machining machine tool. The correct use and maintenance of mechanical spindle has a very important influence on the improvement of machining accuracy and the extension of service life of high-speed machining machine tool.
Do not use compressed air to clean the mechanical spindle, to avoid dust into the spindle gap, and then damage the spindle bearing; When cleaning the area around the main shaft of the machine, although the main shaft is stopped, the machine tool should be energized, and ensure that the main shaft bearing is in the state of air curtain protection;
Mechanical spindle in the process of use pay attention to the cutting fluid should be hit on the cutting tool, do not hit in the spindle end; The tool installed on the mechanical spindle, the tool handle part must be cleaned regularly with a clean soft cloth, to avoid dust into the spindle cone hole, even if not used on the spindle should also retain a tool handle, to protect the spindle cone hole;
New or more than a month of unused mechanical spindle, at the beginning of the work must ensure low speed rotation, to carry out the spindle preheating empty operation; In order to ensure the high accuracy of the mechanical spindle, only good dynamic balance standard cutting tools can be used when running at high speed. When high-precision cutting, the mechanical spindle should be preheated for 30 minutes to achieve thermal stability.
If you can do the above points in the process of using and maintaining the mechanical spindle, it is bound to be able to achieve the effect of twice the result with half the effort. The mechanical spindle manufacturer emphasizes that the mechanical spindle can not overload in any case, which you must keep in mind.
