The use of the roller production system of the nc machine tool power requirements

Power is to maintain energy support part of the system to work normally, it is a direct result of the failure or malfunction caused by system outage or destroy the whole system.In addition, the roller production system is the numerical control system part of the operation data, the data set and the processing program of general store in RAM memory, power system, by the power of backup battery or lithium battery to keep.Consequently, down time is longer, pull out plug or storage may cause data loss, the system can not run.At the same time, due to the roller nc equipment using the three-phase ac 380 v power supply, so security is important part of nc equipment installation work, based on the above reasons, the use of numerical control equipment of the power supply has the following requirements: one, the grid voltage fluctuation should be controlled between + 10% ~ 10%, and the power fluctuation is bigger, the quality is poor, also hide like this kind of high frequency pulse interference, and human factors (such as sudden switch power, etc.).Electricity during peak, such as the work during the day or an hour or so, and in the evening before coming off work, often do poorly, even achieve & plusmn;20%.Make the machine alarm and unable to work normally, and damages to the machine power supply system.The related parameters and even lead to loss of data, etc.This kind of phenomenon, such as CNC machining centers and turning centers have happened on machine tool equipment, and the frequency is higher, should be taken into consideration seriously.Suggestions in configuration of the CNC machine tools is relatively concentrated workshop which has the function of automatic compensation adjustment ac regulated power supply system;A single CNC machine tool is solved individually configurable ac voltage stabilizer.Second, suggested that the mechanical and electrical equipment connected to a single power supply.If you need to use other power supply to some parts of the electrical equipment (e.g., electronic circuit, electromagnetic clutch), the power supply should be as much as possible from the component part of the device for mechanical and electrical equipment (such as transformers, transducers, etc.).For large, complex machinery, including many work together in collaborative way and take up a bigger space machinery, may need more than one power supply, this power supply by the site configuration.Unless the mechanical and electrical equipment using plug\/socket connected directly to the power source, or suggest that the power cord directly connected to the power supply to the power terminal of disconnecting switch.If you do not, for the power cord set independent socket.The power cut off switch handle should be accessible, should be installed in easy operation position above 0.6 m to 1.9 m.Ceiling suggested is 1.7 m.So that we can quickly in the event of an emergency power, reduce losses and casualties.Three numerical control equipment, roller production system to the requirement of compressed air supply system of nc machine tools are generally use a lot of pneumatic components, so the factory person they can clean, dry compressed air supply system network.The flow and pressure should comply with the requirements.Compressed air machine installation away from the nc machine tools.Arrangement, and the size of the gas, according to the plant, consideration should be given to the compressed air supply system network installation frozen in coal, air filter, air storage tank, such as relief valve equipment.Four, nc equipment precision numerical control equipment to the requirement of the work environment generally have constant temperature environment demand, only under the condition of constant temperature, to ensure accuracy of machine tool and the degree of finish.General type nc machine tool for room temperature has no specific requirements, but a lot of practice shows that when the room temperature is too high numerical control system failure rate is greatly increased.Moist environment can reduce the reliability of nc machine tool, particularly in the acid gas larger damp environment, can make the connectors and printed circuit board rust, machine tool electrical failure will increase.Therefore some users, in southern China in the summer and the rainy season when deal with nc machine tools have to wet environment.1, the working environment temperature should be between 0 to 35 ℃, avoid the numerical control machine tool directly sunlight, indoor should be equipped with good lighting equipment.2, in order to improve the precision of machining parts, reduce the thermal deformation of machine tools, such as conditional, nc machine tools can be installed in a relatively closed, equipped with air conditioning equipment factory.3, work environment relative humidity should be less than 75%.Numerical control machine should be installed in places far from the splash, and prevent the workshop dripping.4, stay away from too much dust and corrosive gas environment.
