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.

CNC cutting machine in the processing of cutting parts is the need to follow the instructions to operate, for different materials, the operation steps and attention to the details are different, the following for everyone to talk about cutting thick parts is the need to pay attention to "Skew, 1 to be done in advance The pretreatment of the cut parts, such as the method of repeated forging to evenly organize and clean impurities.
2. Use a coolant with a higher dielectric constant, stronger recovery of insulation, and better mobility and drainage.
3. The feed method of partial feed line feed or active feed two feed back, so that the gap is usefully expanded.
4, greatly improve the pulse voltage, so that the discharge gap increases, water entry and discharge is also relatively easy CNC machine tool industry and macroeconomic dependence, the country's continuous improvement in deposit reserve ratio and other factors, are to equipment manufacturing The industry's CNC cutting machine tool market has brought a lot of impact, while the decline in the sales of ordinary CNC cutting machine tools, low-end machine tool equipment is particularly significant performance of the CNC flame cutting machine is a preheating flame flame temperature adjustment In the actual operation, the length of warm-up time of the CNC flame cutting machine needs to be considered according to the thickness of the cutting, but does it mean that the higher the flame temperature, the better the cutting effect? The Oxygen-Gas Cutting process of a CNC Flame Cutter is a process in which a stream of pure oxygen (at least 99.5%) is ignited and burned on the surface of the workpiece. The heating flame starts by heating the starting point of the workpiece to be cut to the ignition temperature. .
Features and Quality Evaluation of CNC Plasma Cutting Machine CNC plasma cutting machine can cut all kinds of complicated workpieces, and has the advantages of high cutting speed, high efficiency, good cutting surface quality, accurate cutting size, and small thermal deformation of workpieces. Cutting parts can be directly welded and applied without machining. However, CNC plasma cutting machines use plasma arc cutting. Compared with oxygen cutting, CNC plasma cutting machines still have certain defects, which are mainly reflected in the relatively large inclination of the cutting surface, and the smoothness without oxygen cutting. The main criteria for evaluating the quality of CNC plasma cutting are: the inclination of the cutting surface, the cutting depth of the slit, and the amount of slag. A good cutting surface should have an inclination of 3° or less, a cutting depth of 0.15 mm or less, and less slag dross, which can be easily removed. Under the conditions of stable voltage and current, factors affecting the cutting quality include two main reasons besides the quality of the electrode and the nozzle itself: First, the height and stability of the cutting nozzle; Second, the matching of cutting speed and working pressure.
