CNC machining center must meet the following four conditions
1、 Environmental requirements for machining center location
The machining center should be located far away from the vibration source, avoid the influence of direct sunlight and thermal radiation, and avoid the influence of humidity and airflow. If there is a vibration source near the CNC machine tool, the anti vibration groove should be set around the machining center. Otherwise, it will directly affect the machining accuracy and stability of CNC machine tools, make the electronic components in poor contact, cause failure, and affect the reliability of the machining center.
2、 Power requirements
The general machining center installed in the machining workshop, not only the environmental temperature changes greatly, the use of poor conditions, and a variety of mechanical and electrical equipment, resulting in large fluctuations in the power grid. Therefore, the installation position of machining center needs strict control of power supply voltage. The fluctuation of power supply voltage must be within the allowable range and keep relatively stable. Otherwise, it will affect the normal work of CNC system of machining center.
3、 Temperature conditions
The environment temperature of NC machining center is less than 30 degree, and the relative temperature is less than 80%. Generally speaking, there are exhaust fans or air coolers in the CNC electric control box to keep the working temperature of electronic components, especially the CPU constant or the temperature difference changes little. Too high temperature and humidity will reduce the life of control system components and increase the number of faults. With the increase of temperature and humidity, more dust will bond on the integrated circuit board and lead to short circuit.
4、 Use the machining center according to the instruction
Users are not allowed to arbitrarily change the parameters set by the manufacturer in the control system when using the machining center. The setting of these machining center parameters is directly related to the dynamic characteristics of machining center components. Only the gap compensation parameters can be adjusted according to the actual situation.
