With the continuous development of science and technology, CNC machining centers are also developed from CNC milling machines. The gap between them and CNC milling machines lies in the ability of CNC machining centers to automatically switch machining tools. By assembling tools for different purposes on the tool magazine, you can In the one-time clamping process, the machining tool on the spindle is replaced by the automatic tool changer, and then a variety of machining processes can be easily realized. The location of the CNC machining center should be isolated from the vibration source, and the influence of direct sunlight, heat radiation, and humidity and airflow should also be avoided. If there is a vibration source near the CNC machining center, the four sides of the machining center should be provided with anti-vibration trenches. On the contrary, it will directly affect the machining accuracy and stability of the CNC machining center, and indirectly cause poor contact of electronic components, and affect the stability of the machining center. The ambient temperature of the CNC machining center is less than 30℃, and the relative ambient temperature is less than 80%. Normally, there are exhaust fans and air coolers in the numerical control electric control box to ensure that the temperature of the original is within the normal range, and the working temperature of the central processing unit should be stable and the temperature difference should not change much. Excessive ambient temperature and humidity will reduce the service life of the control system components and increase the shortcomings. The increase in ambient temperature and humidity and the increase in dust will cause adhesion on the integrated circuit board and cause short circuits.
