Temperature is also an important factor for turning milling machine tools
The turning milling compound processing machine tool should be far away from the vibration source, avoid direct sunlight and thermal radiation, and avoid being affected by moisture and airflow. If there are vibration sources near the turning milling compound CNC lathe, anti vibration grooves shall be set around the machining center. Otherwise, it will directly affect the machining accuracy and stability of the turning milling composite CNC lathe, lead to poor contact of electronic components, cause failures, and affect the reliability of the turning milling composite CNC lathe.
The ambient temperature of turning milling CNC lathe is lower than 30 ℃, and the relative temperature is lower than 80%. In general, the exhaust fan or air cooler is installed inside the numerical control electric cabinet to keep the working temperature of electronic components, especially the central processor, constant or the temperature difference changes little. Excessive temperature and humidity will reduce the life of control system components and cause more failures. The increase of temperature and humidity and the increase of dust will cause adhesion on the integrated circuit board and cause short circuit.
Generally, the machining center is installed in the machining workshop. Not only does the environment temperature change greatly and the service conditions are poor, but also there are many electromechanical equipment, causing large fluctuations in the power grid. Therefore, the installation position of the machining center needs to strictly control the power supply voltage. The power supply voltage fluctuation must be within the allowable range and kept relatively stable. Otherwise, the normal operation of the CNC system of the machining center will be affected.
The difference between the implementation of turning milling composite processing technology and conventional processing equipment is that the turning milling composite processing center is actually equivalent to the processing of a production line. Therefore, how to formulate a reasonable process route, installation method and select a reasonable tool according to the process characteristics of parts and the process characteristics of turning milling composite processing is the key to achieve efficient precision machining.
The development of turning milling compound machining technology puts forward higher requirements for the development of nc programming technology. Because the application time of turning milling composite processing in actual production is relatively short, in the absence of professional composite processing solutions, a common way is to use general CAM software to plan part of the processing programs, and then the technicians manually integrate the programs to meet the requirements of Dongguan turning milling composite processing machine tools for processing programs.
