Maintenance and Repair Skills of Electric Spindle of CNC Lathe

When CNC lathe products are processed with high speed and precision, the electric spindle is its key functional component. In order to ensure the actual operation requirements of the CNC lathe, the electric spindle must be regularly maintained and repaired. This is not only helpful to reduce the production cost of the product, but also is a prerequisite for improving the production efficiency and processing quality. 1. Operate strictly in accordance with the instruction manual. In the application of CNC machine tools, the operator must strictly follow the instruction manual for relevant operations, especially to understand the basic structure and performance of the electric spindle and related accessories, especially to be familiar with the handling of the electric spindle The basic requirements of installation, cooling, water supply, oil supply, power supply, gas supply, etc., must be strictly controlled during the operation of the super-rated power operation to ensure the performance of the electric spindle and further reduce its maintenance cost. 2. Keep the electric spindle clean. For electric spindles that will not be used in a short period of time, compressed air must be used to completely blow the water in the water cavity. The sleeves and tools of the electric spindle should also be regularly coated with protective oil. A protective cover must be installed at the joint of the air pipe. Dust removal treatment should also be carried out regularly for the operating workshop to prevent the related components of the electric spindle from falling into the dust and affecting efficiency. 3. Strengthen real-time monitoring during operation During the operation of the CNC lathe, the operator must strictly follow the relevant operating technical regulations, and strengthen the real-time monitoring of the air pipe and oil pipe of the electric spindle to check whether the air pipe is leaking, and the oil supply Whether the amount meets the operational requirements. In the operation monitoring, the operator should also pay attention to whether the electric spindle has abnormal noise, whether the temperature of the shell is normal, and whether there are surface quality defects or dimensional tolerances when processing high-precision parts. In the operation of CNC lathes, it is necessary to avoid sudden 'braking' phenomena, which may cause bearing jams or substandard dimensions of workpieces, which is extremely unfavorable for the production process.
