In recent years, we have seen the rapid development of science and technology in our great motherland. This made me feel extremely proud for me as a Chinese. With the advancement of technology and the progress of people, we will join the Chinese cutting machine trading network to make progress together. Join the hotline, we look forward to your call.

The traditional CNC flame cutting machine in operation because of the use of pay control, the assessment of the cutting quality will be a great fluctuation due to the operator's experience, and the integration of the CNC automatic flame cutting machine CNC cutting machine, whether in the cutting quality of cutting efficiency The display is relatively unchanged, and the quality inspection of the processed parts also constitutes a relatively solid inspection step.
In the cutting process using a numerically controlled flame cutting machine, in order to obtain a high quality incision, the height of the cutting nozzle to the surface of the cut workpiece must be kept substantially the same. This can be a bit difficult for manual operations, especially when the cutting surface is not flat or the cutting environment is limited. It is even more important to keep the cutting height stable.
CNC plasma cutting machine has its unique advantages. CNC flame cutting machine is mainly suitable for medium and thick plate cutting and machining equipment. Compared with other similar thermal cutting methods, CNC flame cutting machine has high cutting quality and good verticality. Cutting thickness and other characteristics, is currently the most widely used in the domestic market a class of cutting and processing methods.
1. Sampling detection Sampling inspection is the final threshold for inspection of workpieces. Accuracy needs to be measured on specific details such as the kerf width, cutting plane flatness and verticality of the workpiece to determine whether the processing quality meets the secondary processing requirements. The detailed sampling inspection includes the dimensions of the parts after cutting, the brightness of the section, the grooves, the verticality of the fracture, the slope of the mouth, the height of the blunt edge, the partial nicks, burrs, and residual oxides. The user can find the relevant quality and accept the partial limitations. Reference specification.
Second, write-off marked in a large number of cutting tasks, the inspection of the workpiece can not be reflected in one by one, in order to facilitate the post-inquiries, the need to specify the title of the project on the cutting piece, part number and its own team, in preparation for later check . Of course, here we require the operator to perform at least a sampling inspection before proceeding with the next batch of cutting operations. The NC flame cutting machine should be calibrated to show that the cutting quality does not meet the requirements, in order to avoid rendering a lot of failed parts.
Third, the appearance of introspection The appearance of introspection is after the end of the cutting, the steel cutting surface for a review of the inspection, on the specification of the cutting of the workpiece, the cutting surface should be no cracks, there is no slag and more than 1mm lack of edge, in the arrival After the above requirements, step two can be performed. Otherwise, the relevant parameters of the cutting process need to be cut again after the new review.
After the purchase of the CNC flame cutting machine, it is also necessary to ensure safety and correctness in daily operations. This not only can effectively avoid the damage caused by misoperation of the equipment, but also is an important prerequisite for ensuring life safety. First of all, before starting the cutting machine, it is necessary to fully inspect the various oxygen gas pipelines and valves of the CNC cutting machine to ensure that the pipeline is not leaking and unobstructed, check the power supply voltage and gas pressure, and ensure that the equipment is in compliance. Secondly, in the work of the cutting machine, according to the thickness and material of the unused raw materials, choose the appropriate cutting nozzle, set different cutting speeds and warm-up time, and after the ignition, do not touch the cutting nozzle area.
