Both precision CNC machining and traditional machining are operated by manual operation of ordinary machine tools. During machining, the machine tool is shaken by hand to cut metal, and the accuracy of the product is measured by the eye with tools such as calipers. Modern industry has already used computer digitally controlled machine tools for operations. CNC machine tools can automatically process any products and parts directly in accordance with the procedures programmed by technicians in advance. This is what we call “CNC machining”. Numerical control processing is widely used in any field of all mechanical processing, and it is the development trend and important and necessary technical means of mold processing.
1. Environmental requirements for the location of precision CNC machining centers
The environment of precision CNC machining should be far away from the vibration source, and should avoid the influence of direct sunlight and heat radiation, and avoid the influence of humidity and airflow. If there is a vibration source near the CNC machine tool, an anti-vibration trench should be set around the machining center. Otherwise, it will directly affect the machining accuracy and stability of the CNC machine tool, and cause poor contact of electronic components, failures, and affect the reliability of the machining center.
2. Power requirements
General machining centers are installed in machining workshops. Not only are the environmental temperature changes greatly, the use conditions are poor, but also a variety of electromechanical equipment is large, resulting in large fluctuations in the power grid. Therefore, the location where the machining center is installed requires strict control of the power supply voltage. The power supply voltage fluctuation must be within the allowable range and remain relatively stable. Otherwise, it will affect the normal operation of the CNC system of the machining center.
Three, temperature conditions
The ambient temperature of the CNC machining center is lower than 30 degrees Celsius, and the relative temperature is lower than 80%. Generally speaking, an exhaust fan or air cooler is arranged inside the numerical control electric control box to keep the electronic components, especially the central processing unit’s working temperature constant or the temperature difference changes very small. Excessive temperature and humidity will reduce the life of control system components and cause more failures. The increase in temperature and humidity and the increase in dust will cause adhesion on the integrated circuit board and cause short circuits.
Fourth, use the machining center according to the instructions
When using the machining center, the user is not allowed to change the parameters set by the manufacturer in the control system at will. The setting of these machining center parameters is directly related to the dynamic characteristics of each part of the machining center. Only the value of the gap compensation parameter can be adjusted according to the actual situation.
