Three process engraving machine noise is how to solve?

Spindle as a core part of the CNC engraving machine three process, utilization rate is much, also is one part of the easy problems, of course. Due to the long time high frequency operation, and furthermore, improper use, main shaft is easy to appear some noise. So, in the real operation, some of the noise in the face of the main shaft of the, we should be how to deal with? 1, impurities caused by bearing or overall cleanliness, the abnormal sound of an irregular, voice, when the small, frequently in the high-speed motor solution: to choose a good oil, to improve cleanness of note before the fat, strengthen bearing sealing performance, improve the purity of the installation environment 2, patters patters of sound produced by the vibration and impact of retainer and rolling element, may be produced, no matter what types of grease are under torque, load or radial clearance when it is easier to produce. Solution: to improve retainer precision, choose the bearing clearance small or the exerted load, reduce the torque load bearing, reduce the installation error, choose good fat. 3, buzzing sound motor no-load running is similar as the buzzer sounds, and abnormal axial vibration motor, open or shut down from time to tome hum. Solution: more appear in the lubrication condition is bad, and in the winter and ball bearing motor, main shaft is self-aligning performance is bad, under the influence of the axial vibration of an unstable vibration. 4, a man's voice sound frequency changes according to the bearing rotating speed, the surface waviness is the main cause of noise solution: to improve the bearing raceway surface processing quality, reduce waviness amplitude, bruised, and cooperate with the fixed clearance pre-tightening force, check the free end bearing operation, improve the precision of the shaft and bearing installation method.
