The technique of cutting thick parts by CNC cutting machine

The CNC cutting machine needs to follow the instructions for cutting the cutting parts, and the details of the steps and attention of different materials are different.

1, beforehand processing of the cut parts should be done, such as repeated forging, uniform organization and cleaning of impurities.

2, choose a higher dielectric coefficient, restore insulation to be stronger, activity and sewage solution stronger coolant.

3, the reward is biased feed line or active feed in two way back, so that the gap is useful to expand.

4, greatly improve the pulse voltage, so that the discharge gap increases, water entry and discharge is relatively easy.

The high dependence of the CNC cutting machine industry and the macro economy, the national continuous advance deposit reserve rate and other factors have brought no small impact on the market of CNC cutting machine tools belonging to the equipment manufacturing industry, while the sales decline trend of the common numerical control cutting machine and the middle and low end machine tool equipment is particularly obvious <br / >

The preheating setting of the numerical control flame cutting machine is a means to adjust the flame temperature of the flame body. In actual operation, the preheating time of the CNC flame cutting machine needs to be considered according to the thickness of the cutting, but does it indicate that the higher the temperature of the flame, the better the cutting effect is? The process of cutting the oxygen one of the numerical control flame cutting machine is to ignite a jet of pure oxygen (at least 99.5%) on the surface of the workpiece. The heating flame starts the process by heating the starting point of the workpiece to be heated to the ignition temperature.

CNC plasma cutting machine features and quality evaluation by CNC plasma cutting machine can cut all kinds of complex pieces of work, and has the advantages of fast cutting speed, high efficiency, good cutting surface quality, accurate cutting size, small thermal deformation of the workpiece and so on. Cutting parts can be directly welded and applied without mechanical processing. But the CNC plasma cutting machine is cutting with plasma arc. Compared with the oxygen cutting, it still has some defects. It is mainly reflected in the high inclination of the cutting surface, and the brightness is not cut by oxygen. The main criteria for evaluating the quality of numerically controlled plasma cutting are: the slope of the cutting face, the depth of cut and the number of slag. A high quality cutting surface should be below 3 degrees, the depth of cut should be below 0.15 mm, and the slag will be less and easy to remove. In the condition of stable voltage and current, there are two main reasons that affect the cutting quality except the quality of the electrode and the nozzle itself: the first is the height and stability of the cutting mouth, and the two is the matching of the cutting speed and the working pressure.
