Correct selection of air compressor is the key to using plasma cutting machine

Air plasma cutting machine is a new type of thermal cutting equipment. Its working principle is to use compressed air as working gas and high-temperature and high-speed plasma arc as heat source to partially melt the metal to be cut, and at the same time use high-speed airflow to melt the molten metal. The metal is blown away, creating a narrow slit. The equipment can be used for cutting various metal materials such as stainless steel, aluminum, copper, cast iron, carbon steel, etc. It not only has fast cutting speed, narrow kerf, smooth kerf, small heat-affected zone, low workpiece deformation, simple operation, but also has remarkable advantages. energy saving effect. This requires us to use an air compressor for plasma cutting to assist the use of the plasma cutting machine.

Compared with flame cutting, CNC plasma cutting machine has improved cutting speed and cutting range. In addition to the maturity and perfection of plasma cutting technology in recent years, more and more users and enterprises in the market choose plasma cutting method. Compared with traditional cutting In terms of method, plasma cutting has the advantages of high efficiency, high precision and high stability, and is especially suitable for mass production processing and high-precision cutting requirements. In addition, from the perspective of cost, due to the removal of cutting gas costs, the relative cost of plasma cutting It is more economical, especially when it is applied to mass production, its processing cost control will be more obvious.

When the CNC plasma cutting machine uses air as the working gas, how to choose the air compressor correctly?

Under normal circumstances, when the working air pressure is lower than the air pressure value required by the equipment, the air flow rate input by the air compressor is less than or less than the specified value. High-speed plasma arc, resulting in poor incision quality, incision, and uneven incision.

From the perspective of the air compressor, the reason for insufficient air pressure is mainly due to insufficient input air. In addition, the piston may be caused by the low pressure regulation of the cutting machine air regulating valve, oil pollution in the solenoid valve, and unobstructed air path. It is recommended that users understand 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 display the output pressure from the air compressor. It can be clearly seen; in addition, check the input air pressure before use, check whether the adjustment of the air filter pressure reducing valve is correct, and whether the gauge pressure can meet the cutting requirements. Otherwise, routine maintenance should be performed on the air filter pressure reducing valve to ensure that the input air is dry and free of oil.
