How To Distinguish The Noise Of The Spindle Of The CNC Cutting Machine And How To Deal With It

During the cutting process of the CNC cutting machine, the cutting spindle of the panel furniture cutting machine bears a very important task. As the use time increases, the cutting machine will also have various noises and different problems. The noise produced is different, so do you know how to distinguish the noise made by the spindle of the feeder? Next, Zhongke CNC will give you a detailed summary.

One, the movement of patters and patters

Regardless of the type of lubricant, vibrations and conflicts occur between adherends and rolling elements, and the time for larger bearing torque, load or radial clearance is shorter.

Solution: Improve equipment accuracy, choose bearings with small clearances, or apply pre-tightening force to the bearings, reduce torque load, reduce equipment failures, and choose good lubricants.

Second, the buzzing movement

When the CNC cutting machine has no load on the motor, it will produce buzzing motion, and the motor will vibrate axially, and there will be buzzing sound when it is turned on or off.

Treatment method: In the case of poor lubrication, and in winter with ball bearings at both ends, it is mainly an unstable vibration that occurs under the influence of axial vibration when the shaft alignment function is not good.

Three, impurity sound

If there is a problem with the bearing, it will make an irregular abnormal sound. This kind of sound is sometimes absent, sometimes large and sometimes small, and usually appears repeatedly on high-speed motors.

Treatment method: select good lubricating oil, cleanliness before grease injection, strengthen the sealing function of the bearing, and the cleanliness of the equipment environment

Fourth, the movement of da da

The dynamic and static frequency changes with the bearing speed, and the surface waviness of the parts is the main cause of noise.

Treatment method: improve the surface processing quality of the bearing raceway, reduce the waviness amplitude, reduce bumps, modify the clearance pre-tightening force and cooperation, check the operation of the free end bearing, and improve the accuracy of the shaft and the bearing seat.

These are some noises that usually appear in the processing of CNC cutting machines. When these noises occur, we must first make a correct judgment, and then use different methods to deal with different noise problems.
