CNC flame cutting machine processing for the flatness of the steel plate placed there is a certain requirement, in accordance with the standards promulgated by the Ministry of Metallurgical Industry, continuous cutting slab cutting surface of the end of the cut should not exceed 20mm. However, in actual operation, many users will find that when they are cutting and processing, there will often be uneven board problems beyond the above standard range. The main reasons for the uneven surface of the flame cutting machine processing are roughly divided into the following four aspects. The user can refer to and compare according to their own situation. The car engine systemis the heart of the automobile, which provides the driving force for the automobile, and it is related to the power, economy and environmental protection of the automobile. In simple terms, the engine is an energy conversion mechanism, the gas (diesel) or natural gas heat, through the sealed cylinder combustion gas expansion, push the piston to work, change to mechanical energy, this is the most basic principle of the engine.
Engine systems comprise on the following:
These are the systems for petrol engines. Diesel Engines have similar systems except for fuel System and ignition System. Some parts of the system are built into the engine, some parts are attached to the engine and other parts are located on the body panels in the engine compartment.

First, the adjustment of the flame, the torch must be adjusted to the best flame, too large or too small will affect the billet cut surface;
Second, the fixed position of the cutting torch must be highly reasonable and vertical. There must be no deviation between the front and the back;
Third, the combination of the car parts must be tight, and the gap between the bearing and the pin hole must not be too large, because the cutting process is carried out simultaneously with the movement of the casting blank. Loosening of the parts of the car will cause the swing of the cutting torch, thereby affecting the cutting. effect;
Fourth, it is the swing of the cutting gun in the billet caster cutting machine, and the positioning control part sloping plate should not be short. The on-site swash plate is properly lengthened by about 7cm, and the balance wheel is lengthened by about 2cm, which solves the problems caused by the trolley during the movement of the torch. Jitter problem.
CNC flame cutting machine in the entire process of automated operation, the traditional cutting method is not only an effective alternative to improve the cutting speed and efficiency, but also to the cutting quality can also achieve high-quality stable cutting. However, in actual production and application, many companies will reflect differences in the quality of flame cutting, sometimes good and sometimes bad.
Among the operating points of the CNC flame cutting machine, the design of the fire timing is a relatively empirical process. In some of the previous technical articles, we have also provided some flame cutting and adjusting technologies for fire fighting, but from the actual operation Say, the flame cutting machine also needs to adjust the thickness from the cutting thickness, taking into account the current domestic CNC flame cutting machine is mainly used for heavy plate cutting process, this situation for everyone to explain in detail.
Flame cutting is the most basic cutting method. In order to achieve the best cutting effect, there are many aspects to be noted in the cutting process setting. In the use of different gases, different cutting nozzle cutting will also be different, in general, the cultivation of a mature flame cutting operator takes about 3 months to operate the running-in, especially like the hand-held cutting this kind of manual cutting method In the past, but in view of the numerically controlled cutting equipment, the above-mentioned time has to be shortened a lot. This aspect lies in the fully automated working mode of the numerical control equipment. On the other hand, it is that the current numerical control cutting technology is increasingly perfect. For thick steel plates with a thickness greater than 50 mm, flame cutting, also called oxygen cutting, is generally used. The process is roughly as follows:
1, according to the thickness of the cutting steel plate to install the appropriate diameter of the cutting nozzle;
2, adjust the oxygen and gas pressure to the specified value;
3. Ignite the preheating flame with a cutting igniter, then slowly open the preheating oxygen valve, adjust the flame length of the white heart, make the flame a neutral flame, and preheat the cutting point;
4. Only the preheating flame is used to heat the cutting starting point, the cutting nozzle is perpendicular to the surface of the steel plate, and the tip of the flame white heart is 1.5 to 2.5 mm away from the surface of the steel plate;
5, when the starting point reaches the combustion temperature (red and red), open the cutting oxygen valve and cut it instantly;
6. After confirming that the lower surface of the steel plate has been cut, move the cutting nozzle along the cutting line at an appropriate speed to continue cutting forward.
