The spindle motor is an important part of woodworking engraving machine, one of the more vulnerable parts, maintenance and usually take measures to maintain, to ensure its normal operation and extend its life, there is an important role. We from the actual situation, the following summarizes the spindle motor maintenance methods, for your reference learning
1, to carefully read the instructions of the spindle motor, control their operating specifications, according to regulate the use of the spindle motor, which is the most important.
2, to establish a sense of caring for and against the spindle motor, its sense of caring for the implementation into practice is to develop "a finished work is necessary to clean the spindle motor" habits! If the habits, the spindle motor maintenance work on the most important done!
3, kept clean and dry air into the spindle.
4, removed from the machine spindle, spindle applications trachea Chuijin residual water cooling chamber, keeping the internal clean, do not have remnants to prevent rust, clogging water hole; short-term temporary need, should be painted anti-spindle appearance rust oil. Plus the shaft protection device, put in a dry place.
5, the long-term without the spindle should seal, start-up, in addition to using gasoline to wash away the surface rust oil, shall do the following: 1) through the mist for 3-5 minutes, twist the shaft by hand, feeling no entrapment
2) detection of the insulation with a Megger should normally be ≥ 10 megohms
3) power first 1/3 rated speed running 1 hour, increases the speed of 1/2 rated speed 1 hour when no abnormal phenomenon, without exception and then one hour at rated speed operation
4) to keep the ball with precision at high speed grinding spindle rotation accuracy
5) spindle speed according to different uses can be high-speed grease and oil mist lubrication two ways
6) the temperature rise caused by the spindle rotation speed, coolant circulation system using flow to eliminate
