What are the problems need to pay attention to the large -scale Dragon Gate CNC processing? In the processing operation of the Longmen CNC, the relative position of the spindle and the rotary shaft is relatively fixed. The actual production and theoretical knowledge are not exactly the same. The relative space between the two axes does not have to be relatively fixed. This is because in the production plant of lathe equipment, the bearing components that form a spindle may have different degrees of errors, and during use, they will be affected by temperature, work strength and lubrication during use.
Due to the different precision of the main axis bearing, the hand -assembled quality of the main shaft box is different, the beating caused by mechanical vibration during the processing of the spindle and rotating components, the roundness of the bottom shaft shaft axle is unstable during the manufacturing process. And concentric error. These factors will affect the geometric accuracy of the main axis of CNC.

In addition to the geometric accuracy error generated by the main axis in the Dragon Gate CNC processing, due to the friction and inertia matching of the servo motor in the Dragon Gate CNC processing, the trajectory may also affect the position accuracy of the machine tool. Some parts that require uninterrupted work, such as cylinder pumps, motors, hydraulic presses, etc., require long -term continuous work (even 24 hours).
During the work, friction deforms certain internal parts due to thermal expansion, and deforms due to the heat of processing, which leads to the deviation between the actual production size of the part and the designated size. Due to the asymmetry of the internal heat, the deformation of the production and processing parts due to the asymmetry of the internal heat, the thermal deformation of the CNC lathe equipment parts will have a vital impact on the position accuracy of the machine tool.
