Analysis of Spindle Noise of CNC Cutting Machine

CNC cutting machineAs one of the important machines in the panel furniture production line, the requirements for machining accuracy and stability are high. The factors that affect the machining accuracy of CNC cutting machine are: spindle, Rail, adsorption platform, bed structure, assembly process, etc. In this article, Anna Solution Technology Co., Ltd. simply analyzes 4 situations of noise in the spindle;
1. If the motor makes a humming sound when it is running under no load, and the motor has an abnormal axial vibration, a humming noise occurs when turning on or off, it means that the lubrication state of the spindle is not very good, or the shaft alignment performance is not good. Good to produce unstable vibration. To increase lubrication.
2. If the retainer and the rolling elements vibrate, or bear torque, load, or radial clearance, it is easy to produce pattering noise. To solve this problem, to improve the accuracy of the retainer, the bearing should be selected with a small clearance or preload on the bearing, reduce the moment load, reduce the installation error, and select good quality grease.
3. If the spindle of the CNC cutting machine makes a rattling sound, the frequency changes with the running speed of the bearing, it is necessary to improve the machining quality of the bearing raceway surface, reduce the amplitude of the waviness, and avoid bumps. View.
4. If the bearing emits irregular impurity sound, the sound is loud and sometimes small, and good grease should be selected to improve the cleanliness before grease injection and strengthen the sealing performance of the bearing.
The above 4 kinds of noises are often made by the spindle during the machining process. Regarding these different noises, make correct judgments, and then deal with them according to the problem. Anna Solution Technology Co., Ltd. reminds CNC cutting machine users, use the machine in strict accordance with the operating specifications, and do a good job of daily maintenance, which can not only avoid failures, but also increase the service life of the machine.
