The development of woodworking machinery is very rapid. In order to meet the needs of the woodworking industry, some traditional woodworking machinery has been completely replaced by CNC woodworking machinery. There are mainly two types of multifunctional spindles in CNC woodworking lathes: air-cooled spindles and water-cooled spindles. The difference between the two is that the water-cooled spindle is controlled by frequency conversion, and the air-cooled spindle is divided into variable frequency control and non-frequency control. The main focus of the editor today is on the maintenance and maintenance of air-cooled spindles, and I hope to help everyone.
1. When the electric spindle is found to be above the sound or the vibration is abnormal, the machine should be stopped immediately to check the bearings, and new bearings must be replaced if necessary. When a strange smell or sudden stop occurs during operation, the power should be cut off immediately, and the stator's resistance to ground and three-phase resistance should be measured with a shaker. The loss of insulation resistance means the stator is burned out. The stator should be replaced at the factory.
2. When the electro-spindle is not used for a long period of time, compressed air is used to blow away the residual cooling liquid in the cooling pipe, and the electro-spindle is rust-proofed. After the electric spindle is stored or deactivated for 6 months, it must be replaced with new grease before use, otherwise it will affect the life of the electric spindle.
3. In order to extend the service life of the electric spindle, the new electric spindle or the electric spindle with new bearings should be equally divided into 4-8 gears in the speed range, and the speed will be increased after 30 minutes of each segment to avoid direct high-speed operation and shorten the use of bearings. life.
24. After holidays, start using the electric spindle for half an hour after no-load operation.
Note: The electric spindle is a new technology that integrates the spindle of the machine tool with the spindle motor. It is mainly used in the field of CNC woodworking lathes. The emergence of electro-spindle technology has eliminated the use of pulley drive and gear drive. The main shaft of the lathe is directly driven by the built-in motor, which shortens the length of the main transmission chain of the lathe to zero, and realizes the "zero transmission" of the woodworking lathe.
The above is some maintenance and maintenance knowledge that Husen CNC has summarized for everyone based on many years of experience. I hope to help you. If you need other questions about CNC woodworking machinery, please feel free to contact us!
