Treatment of section defect of CNC flame cutting machine in

Part of the article: Popularity:Time:2018-07-03 16:28

In the process of cutting the metal cutting flame cutting process, there may be various quality defects on the cutting section and the upper and lower surfaces. Here we take the numerical control flame cutting machine as an example to summarize the phenomena similar to the quality defects of the plate cutting, and analyze the causes of the defects.
1. numerical control flame cutting machine produces water droplet shaped string of molten beans.
Such defects are mainly manifested in the upper edge of the cut to form a bunch of water droplets of molten beans. The main causes can be classified into two aspects:
One possibility is that the surface of the steel plate produced by the flame cutting machine is corroded or oxidized at the early stage.
The second may be that the height control between the cutting nozzle and the steel plate of the flame cutting machine may be too high or too low, and the high temperature of the preheating flame may also be the reason.
2. CNC flame cutting machine appears edge edge collapse.
Such defects are mainly manifested in the excessive melting of edges, resulting in rounded corners. The main causes can be classified into two aspects:
One possibility is that the cutting speed of flame cutting machine is too slow and the preheating flame is too strong.
Secondly, it may be that the height between the cutting torch and the workpiece is too high or too low; the cutting nozzle number is too large, and the excess oxygen in the flame is too high.
3. CNC flame cutting machine processing edge edge collapse and appear eaves.
Such defects are mainly manifested in the edge of the incision forming eaves shaped convex collapse side, the main causes can be summarized into three aspects:
One of them may be due to the excessive preheating time of the flame cutting machine.
Second, it may be that the cutting torch height is too low during the cutting process, resulting in the close proximity between the cutting nozzle and the steel plate.
In the end, it may be that the cutting speed of the flame cutting machine is too slow, or the cutting type is too large and the excess oxygen in the preheated flame is caused by several reasons.
