High-speed machining technology is developing rapidly, and to promote this trend is the CNC machine tools, how to make good use of CNC machine tools performance and safeguard the accuracy of machine tools, is vital, now combined with actual experience, talk about the machine the power of some of the details need attention and common sense.
Power system is to maintain the energy to work to support part of it a direct result of failure or malfunction is caused by system downtime or damage to the entire system. In addition, the numerical part of the operating system data, setting data and processing procedures normally stored in RAM memory, the system power, the power reserve by lithium batteries, or to maintain. Thus, down a long time, plug the power or memory can cause data loss, the system can not run.
Meanwhile, numerical control equipment using three-phase AC 380V power supply, so the safety of CNC equipment pre-installation work is an important part of the above reasons, the power of CNC equipment have the following requirements:
First, the grid voltage fluctuation should be controlled between +10% to -15%, and our power fluctuations, poor quality, but also hidden like a high-frequency pulse interference of this kind, coupled with man-made factors (such as a sudden wind up power, etc.). Electricity during peak periods, such as during the day or an hour before work and evening, often ultra-poor more, even up to ± 20%. So that the machine can not carry out normal police work, and the machine power system damage. Even lead to loss of data and other relevant parameters. This phenomenon, in the CNC machining centers or turning centers, machine tool equipment have occurred, and a higher frequency, attention should be paid.
Recommended a higher concentration of CNC machine shop configuration with automatic compensation for regulatory function of powering an AC system; single CNC machine can be configured individually to solve the AC voltage regulator.
Second, the proposed mechanical and electrical equipment connected to a single power supply. If you need additional power supply to some parts of electrical equipment (such as electronic circuits, electromagnetic clutch), the power should be composed of as much as possible from electrical equipment for the mechanical part of the device (such as transformers, transducers, etc.). Including many large and complex machinery to work in a synergistic manner with the mechanical and occupy a larger space, you may need more than one introduction of power, this power to the site configuration to be.
Mechanical and electrical equipment unless the use of plug / socket connection directly to the power supply, it is recommended that the power cord directly connected to the power switch off the power supply terminals. If this can not, you should set up a separate power line for the terminal blocks.
Power cut off switch should be easy to close the handle, easy to be installed in the location of more than 0.6M ~ 1.9M rooms. The upper limit recommended for 1.7M. This case quickly in the event of an emergency power, to reduce damage and casualties.
Third, numerical control equipment for compressed air supply system, CNC machine tools are generally required to use a lot of pneumatic components, so the plant should be access within a clean, dry compressed air supply system network. The flow and pressure should meet the requirements. Confidential compressed air from CNC machine tools installed in the place. According to the arrangement of the situation within the plant, the size of gas consumption, consideration should be given to the compressed air supply system network installed in the chilled air of coal, air filter, gas tank, safety valves and other equipment.
Fourth, numerical control equipment requirements for the work environment is generally a heated precision CNC equipment, environmental requirements, and only at a constant temperature, to ensure the accuracy and degree of processing machine. CNC machine tools for ordinary room temperature there is no specific requirement, but a lot of practice shows that when the temperature is too high failure rate of numerical control system greatly increased.
Humid environment will reduce the reliability of CNC machine tools, especially in the larger wet sour gas environment, make printed circuit boards and connector corrosion, electrical machine failure will increase. Therefore, some users in southern China in the summer and the rainy season, CNC machine tools environment dewetting response measures.
1, the working temperature should be between 0 ~ 35 ℃, avoid direct sun exposure for CNC machine tools, indoor lighting should be equipped with good lighting.
2, in order to improve the accuracy of machining parts, reduce the thermal deformation of machine tools and, if conditions, CNC machine tools can be installed in a relatively closed, the installation of air conditioning equipment within the plant.
3, the working environment should be less than 75% relative humidity. CNC machine tools should be installed away from the splashing of the place, and to prevent plant drip.
4, away from excessive dust and corrosive gas environment.
