If the brain is the most important part of the human body, then the spindle is the core component of the micro engraving machine. Now the quality of the spindle used in the fully automatic CNC jade micro engraving machine on the market is relatively high, so the price is relatively high, so pay more attention to it. Maintenance and maintenance. The jade carving machine spindle is mainly divided into an air-cooled main shaft and a water-cooled main shaft. Due to the working environment, the spindle is the largest equipment accessory for contacting workpieces and scraps, and the performance of the spindle greatly affects the quality of the finished product. Therefore, we must do the spindle maintenance and maintenance work in daily production and processing. With all the details in place, the life of the spindle motor can be greatly extended.
(1) After working every day, use a vacuum cleaner to clean the scraps on the rotor end of the spindle motor and the motor terminals to prevent debris from accumulating on the rotor end and the terminal block, so as to prevent waste from entering the bearing and accelerating the wear of the high-speed bearing. ; Avoid the waste entering the terminal block, causing the motor to short-circuit and burn.
(2) Each time the card is loaded and replaced, the cap of the cap must be unscrewed. The tool cannot be replaced by directly inserting and removing the tool. If the card is jammed, do not force it out. The end of the spindle and the front end cover must not be impacted, otherwise the precision of the fine bearing and the spindle will be destroyed, resulting in the loss of the accuracy of the spindle reverse rotation.
(3) After the knife is unloaded, clean the chuck and the cap to prevent debris from adhering to it. The placement of the tool must cover the reverse rotation accuracy, otherwise it will cause severe vibration, affecting the quality of the engraving and bearing life.
