CNC plasma cutting machine for sale at low price
CNC plasma cutting machine is mainly used for metal processing of carbon steel, stainless steel, brass, aluminum and other conductive metals.
Plasma cutting is the use of high-speed air jets ejected from a nozzle at high temperature for ionization to form conductors. When an electric current is passed, the conductive gas forms a high temperature plasma arc. The heat of the arc locally melts (evaporates) the metal at the cut of the workpiece, a processing method that uses the power of high-speed plasma gas flow to remove molten metal to form a cut. The slender, stable plasma arc created by the annular airflow technology ensures that any conductive metal can be cut smoothly and economically. A plasma generator and a torch allow manual cutting. However, manual hand-held cutting has low efficiency, poor cutting accuracy and poor cutting quality. For the cutting of complex graphics, the process is often cumbersome or powerless. In order to meet the demand for faster and higher quality mass production cutting, CNC plasma cutting equipment came into being. This is an inevitable requirement of modern industrial production. CNC plasma cutting is to provide an automatic digital control platform for plasma cutting machines. Combined with an easy-to-use CNC system and machine tool platform, it realizes the automation of plasma cutting and meets the high-efficiency and batch processing requirements of modern industrial production. CNC plasma cutting machines are divided into dry plasma, semi-dry plasma, underwater plasma; ordinary plasma, fine plasma, and laser-like plasma are determined according to the cutting quality.
Main application of CNC plasma cutting machine
Stainless steel, cast iron, copper, aluminum and other non-ferrous metal plates, etc., are mainly used for plane cutting irregular graphics. In theory, as long as you can draw graphics with AUTOCAD, you can cut 2 times the width of the plasma slit that cannot be cut.
A complete CNC plasma cutting machine is mainly composed of plasma power supply, CNC system, plasma table and air supply device (air compressor). The plasma generator and its torch group directly determine the cutting quality, the CNC system and the machine tool directly determine the cutting accuracy, and the gas supply device directly affects the cutting quality, which is also a necessary condition for the plasma generator to achieve cutting quality.
