How to use a CNC plasma cutting machine Touch the torch roller to the workpiece, adjust the distance between the nozzle and the workpiece plane to 3~5mm, and turn on the torch switch. The plasma arc is ignited, and after cutting through the workpiece, it moves at a uniform speed in the cutting direction. The […]

The CNC flame cutting machine is the earliest and best CNC cutting equipment. The introduction of flame cutting with numerical control technology realizes the automation of the whole cutting process, significantly improves the cutting quality of steel blanks (size range and cut quality, which can replace part of mechanical processing), and high production efficiency (continuous […]

In the nesting process, the steel plate can be used to the maximum extent only if the common edge cutting is realized reasonably. At the same time, to reduce the deformation of the steel plate, it is necessary to leave a suitable distance between the part contour and the edge of the steel plate, group […]

With the continuous development of the steel structure industry, the component form has gradually developed from a single H-shaped beam-column to diversified and complicated. At the same time, the precision requirements for the processing of complex components by the manufacturer are also getting higher and higher, especially the lower parts of special-shaped parts. The material […]

For a long time, metal flame cutting has been using acetylene + oxygen process mode or propane industrial gas + oxygen process mode. In the field of industrial cutting, acetylene has been used for a hundred years, but acetylene gas is flammable and explosive and has a low safety factor. The production process consumes energy […]

In the machinery manufacturing industry, the production of welded structural parts accounts for a large proportion. The quality of structural parts directly affects product quality, especially appearance quality. The first step to improve the quality of welded structural parts is to improve the cutting quality of plates. In plate cutting, flame gas cutting is one […]

Because CNC flame cutting has the advantages of high cutting efficiency, low cost, good kerf quality, high dimensional accuracy of cut parts, and high material utilization rate, it is used more and more widely in machinery manufacturing enterprises and gradually replaced traditional manual cutting. And semi-automatic cutting, greatly improving production efficiency. Due to the high […]

Because of the different types of fuel gas, the cutting flame can be divided into oxygen-acetylene flame, oxygen-propane flame, and oxygen-natural gas flame. Among them, the oxygen-acetylene flame burns to produce a very high temperature (about 3200°C), and the heat is concentrated, which is the flame often used in cutting. By adjusting the mixing ratio […]

Flame cutting is a common method for rough processing of steel plates. It is a relatively mature thermal cutting method. The cutting metal thickness ranges from 1 mm to 1 meter and is suitable for cutting steel plates above 20 mm. Flame cutting uses the high temperature generated during the combustion of iron oxide to […]
