The famous American quality management scientist said that the 20th century is the century of productivity, the 21st century is the century of quality, and quality is the most effective weapon for occupying the market peacefully. The industry of cutting machines is very useful in such evaluations. Details:/
There are many factors that affect the cutting quality of the gantry type CNC plasma cutting machine. In addition to the design parameters of the cutting machine, it is also related to the control and cutting process.
If a manual adjustment method is adopted, the height of the cutting nozzle from the steel plate is controlled to 6 to 8 mm. Through a series of cutting tests, it can be confirmed that the cutting quality has been significantly improved. Now described as follows: CNC plasma cutting machine can be used to cut a variety of complex-shaped workpieces, and has the advantages of fast cutting speed, high efficiency, cutting surface quality, precision cutting size, small thermal deformation of the workpiece and other advantages. However, the Gantry-type CNC plasma cutting machine uses a plasma arc for cutting, and it is compared with oxygen cutting.
The height of the cutting nozzle from the steel plate is controlled by the arc pressure height controller, and the dynamic positioning accuracy can reach ±0.013 姗, so the height of the cutting nozzle and the steel plate can be maintained unchanged. Therefore, the inclination of the cutting surface is small and average. , And good finish.
A good cutting surface should have a slope of less than 30 degrees, a cut line depth of less than 0.15 mm, and less slag dross, which can be easily removed. Gantry-type CNC plasma cutting machine is an important application classification of thermal cutting processing. It has good performance in cutting efficiency and cutting accuracy. However, with the current situation of most production enterprises in the country, it is truly capable of high quality and efficient operation. Less or less, what restricts the operation level of the enterprise gantry type CNC plasma cutting machine, Wuhan Xinhong Albert CHAN analysis thinks mainly reflected in the following aspects:
1. Cutting mouth height and indiscriminately: The parts cut by the gantry CNC cutting machine can be directly welded and applied without mechanical processing. The main criteria for assessing the cutting quality of CNC plasma cutting machines are: the inclination of the cutting surface, the cutting depth of the slit, and the amount of slag.
2. Matching of cutting speed and working pressure: Gantry-type CNC flame cutting machine is a kind of electromechanical integration used to cut metal sheet blanks to improve predecessor equipment. It has been widely used in shipbuilding, machinery manufacturing and other industries. When manually adjusting the height of the cutting tip from the steel plate, the cut steel plate should be laid as flat as possible to reduce the number of adjustments of the cutting torch and ensure that the torch cutting process is not disturbed. There are still some defects, mainly reflected in the greater inclination of the cutting surface, the smoothness is not good for oxygen cutting.
In addition, in order to improve the cutting quality, we conducted a comprehensive cutting test, analyzed and collected according to the test data, and obtained the best working parameters of the CNC plasma cutting machine.
