Improve the quality of CNC gantry cutting machine and the setting of cutting point

On the one hand, the cutting quality of CNC gantry cutting machine is related to the accuracy of the equipment, and on the other hand, it is directly related to the fire adjustment and operation level of the operators. The cutting effect of flame cutting is also different according to the cutting gas used. After purchasing two sets of equipment, the cutting effect of cutting a workpiece at the same time is not the same, the reason is that the operator does not grasp the fire adjustment link in place.

  To use the CNC gantry cutting machine well, first of all, it is necessary to skillfully control the fire adjustment. In terms of gas source, most of the oxygen in the processing site of the general enterprise is the oxygen supply for the pipeline, and the pressure and purity of the oxygen can generally meet the requirements for use. The cutting gas is mostly bottled gas supply, 30kg per bottle. In the scale of 5 machines and 5 streams, the use time is about 2 hours. The bottled gas pressure fluctuates greatly, which directly affects the gas flow and affects the cutting quality. In addition, the gas source pressure fluctuates greatly at the beginning and end of the use process of bottled gas. It is a good way to use warm water heating on site to ensure the stability of the gas source.

  To ensure the cutting quality of the CNC gantry cutting machine, it is necessary to regularly check whether there is leakage or aging in the pipelines, joints, etc., regularly clean and lubricate the bearings, guide rails, etc., and clean the cutting nozzles, cooling water pipes, etc. It is necessary to complete some routine routine work on a regular basis to ensure the normal operation of the equipment, and then to improve and improve the cutting effect. The adjustment of the flame is related to other factors, especially for the type and thickness of steel, which requires us to pay attention to summarizing and accumulating experience in daily work, strengthening learning and research, and mastering various knowledge.

     The gantry CNC cutting machine uses the CNC system to walk according to the cutting trajectory under the set cutting graphic trajectory to complete the entire cutting operation. However, in practical applications, considering various factors such as the shape of the steel plate, the size of the cutting parts, and the thickness and material of the plate, where should the cutting torch start on the plate surface?

   In general, it is recommended that users design the cutting point at the edge of the steel plate. Taking into account the preheating problem of flame cutting, using the edge as the starting point will prolong the life of the wearing parts. At the same time, in order to improve the quality of the cut surface of the part, it is recommended to increase the length of the lead appropriately when using edge cutting to improve the cutting quality.
