How big air compressor is used for gantry CNC cutting machine

Compared with traditional cutting methods, plasma cutting has the advantages of high efficiency, high precision and high stability. It is especially suitable for mass production and high-precision cutting requirements. In addition, from a cost perspective, due to the For cutting gas costs, plasma cutting is relatively more economical, especially when it is applied to mass processing and production, its processing cost control will be more obvious. The use of plasma cutting requires an air compressor.

When using plasma cutting, an air compressor is also required to ensure that the above problems will not occur. The principle is to use high-pressure gas to blow the molten slag away from the section. This is why it is necessary to equip the CNC plasma cutting machine with an air compressor. As for the use of inert gas, CO2, and nitrogen assisted plasma cutting, related accessories need to be replaced, but the principle is still the same.

On the other hand, plasma arc cutting machines mostly rely on gas pressure to control the flow, because when the gun body aperture is fixed, the gas pressure is controlled and the flow is controlled. The gas pressure used to cut a certain thickness of material is usually selected according to the data provided by the equipment manufacturer. If there are other special applications, the gas pressure needs to be determined through actual cutting tests. Therefore, in order to achieve good cutting quality, not only the technicians need to operate normally according to the process, but also need the technicians to have cutting adjustment experience. The air compressor of the plasma cutting machine is compatible with most equipment. The user needs to ensure that the pressure on site is stable, otherwise it will also affect the cutting quality of the product.

The air compressor is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy, and is a pressure generating device for compressed air.

When the CNC plasma cutting machine uses air as the working gas, what are the requirements for the air pressure? How should it be matched correctly? Under normal circumstances, when the working pressure is lower than the pressure value required by the equipment, the air flow rate of the air compressor is less than the specified value. At this time, the ejection speed of the plasma arc will be weakened, and high energy and high energy cannot be formed. Plasma arc at high speed, resulting in poor incision quality, impermeability, and incision buildup.

CNC plasma cutting machine has improved cutting speed and cutting range compared with flame cutting. In addition to the maturity and improvement of plasma cutting technology in recent years, more and more user companies choose plasma cutting in the market. Compared with traditional cutting methods, plasma cutting has the advantages of high efficiency, high precision and high stability. It is especially suitable for mass production and high-precision cutting requirements. In addition, from a cost point of view, due to the removal of cutting Compared with gas costs, plasma cutting is more economical, especially when it is applied to mass processing and production, its processing cost control will be more obvious.

The choice of air compressor is mainly based on the working pressure and flow rate of the pneumatic system.

The working pressure of the gas source should be about 20% higher than the highest working pressure in the pneumatic system, because the loss along the way and the local loss of the gas supply pipeline should be considered. If the working pressure requirement in some parts of the system is low, a pressure reducing valve can be used to supply air. The rated discharge pressure of the air compressor is divided into low pressure (0.7~1.0MPa), medium pressure (1.0~10MPa), high pressure (10~100MPa) and ultra high pressure (above 100MPa), which can be selected according to actual needs. The common use pressure is generally 0.7-1.25.

From the perspective of the air compressor, the main reason for the insufficient air pressure is that the input air is insufficient. In addition, the piston may be the cutting machine's air regulating valve. The pressure adjustment is too low, the solenoid valve is oily, and the air path is not smooth. Wait. Wuhan Linghang Numerical Control Technology Co., Ltd. recommends that users know exactly their own processing requirements, including cutting material, cutting thickness and cutting time, and choose a suitable air compressor based on the above factors. When the air compressor cannot meet the cutting requirements, we will The output pressure of the compressor can be clearly seen on the display; in addition, the input air pressure should be checked before use, and the air filter pressure reducing valve should be adjusted correctly and whether the gauge pressure display can meet the cutting requirements. Otherwise, the air filter pressure reducing valve should be maintained daily to ensure that the input air is dry and free of oil.
