- 1. With the advancement of technology and the development of science and technology, the development scale of Guangdong CNC machining center is getting bigger and bigger. Therefore, the requirements for the stability of bearings at high speeds are getting higher and higher. The temperature rise of the machine tool spindle bearing is an important factor that limits the bearing speed. Under normal circumstances, the correct selection of bearing type, worse grade, configuration method, clearance (preload) size, smoothing agent and smoothing method can be used to a certain extent. Improve the high-speed performance of rolling bearings.
- 2. Lifespan and load capacity Regarding heavy-duty machine tools or cutting machine tools, the load capacity of the air filter bearing should be the first priority.As for general machine tools, the life span of the spindle composition refers to the life span of maintaining the accuracy of the spindle. Therefore, the accuracy of the bearing is required to meet the life expectancy of the spindle assembly.
- 3. Rigidity and vibration resistance are the quality assurance of aluminum cavity CNC machining. The spindle system must have sufficient rigidity, otherwise there will be large re-imaging errors and even tremors.
- 4. Noise In high-speed grinding machines, the noise of the grinding head bearing is an important component of the overall noise, and it is advantageous to choose low-noise rolling bearings.
In the fault detection of CNC machining of aluminum cavity, the reasoning can be carried out from two aspects, namely forward and reverse. Proceeding: starting from the cause of the problem, exploring its functional connection, and checking the influence of the cause on the result.
It is to reason based on the possible causes of the problem, and see if it is consistent with the problem, to confirm the problem.
Choose the reasoning method, the initial reasoning analysis goal is often ambiguous, because, among the many causes or phenomena, it is necessary to find out their common characteristics.
Then confirm the fault point and follow the reasoning step by step, and you will realize that the personality characteristics of the reasoning analysis target are the fault location you are looking for.
