CNC flame cutting machines (CNC Cutting Machine) is a digital program-driven machine motion, equipped with flame cutting systems, the use of numerical control system to control the switching of the flame cutting system, cutting of steel and other metal materials. The mechanical and electrical integration of cutting equipment for CNC flame cutting machine. CNC flame cutting machines can be divided into three parts: the numerical control system, flame cutting systems, drive systems, different manufacturers essentially the same. CNC flame cutting machine English name of flame cutting machine, CNC flame cutting machine cutting thickness of the carbon steel cutting capacity and cutting costs lower, but there are cutting deformation and cutting accuracy is not high and the low cutting speed, cutting the warm-up time perforation for a long time, difficult to adapt to the needs of the fully automated operation. Its applications are mainly limited to carbon steel, the large thickness of sheet metal cutting, gradually in thin carbon steel plate cutting, plasma cutting instead. Commonly used CNC flame cutting machine gas, including propane, acetylene, natural gas, gasoline, liquefied petroleum gas and other, their common ground is burning to the formation of local high temperature, CNC flame cutting machine, in order to better improve the cutting quality, so that gas to fully burn the formation of a higher temperature, usually in conjunction with high purity oxygen as an adjunct, relative enterprises and users, cutting the oxygen supply of the purity of how to control and to grasp it is particularly important, the oxygen can improve the cutting of low carbon steel The speed of the material.hydraulic machines
Oxygen cutting, cutting mode and flame cutting are to imagine the high-temperature high-energy plasma arc cutting faster, but it must be used in conjunction with the high temperature oxidation resistance of the electrode on the electrode from the arc when the anti-shock protection to extend the electrode lifetime. The following summarizes some experience in this area for your reference.hose cutting machine
In the flame and plasma cutting machine, the purity of oxygen is an important factor to affect the gas cutting process and quality. Oxygen purity, not only the cutting speed is greatly reduced, the cutting surface roughness, the incision under the edge of the stick residue, and the increase of oxygen consumption. Oxygen purity from 99.5% to 98%, representing a fall of 1.5 percent, cutting speed decreased by 25%, and oxygen consumption increased 50%.
Is generally believed that the oxygen purity is below 95%, will not be able to gas cutting, gas cutting incision with no sticky residue, oxygen purity to 99.6%. So for CNC flame cutting machine, the oxygen purity can not be ignored.
Under normal circumstances, the ordinary cutting nozzle gas cutting, in the case of low pressure, with increasing pressure, cutting speed is also increased, but when the pressure of more than 0.3MP, cutting speed is worse; con tinue to increase the pressure, not only cutting reduced speed, the incision will be wider, the incision section will be more rough. Diffusion-shaped cutting tip gas cutting, the cutting oxygen pressure in line with the design pressure of the cutting nozzle, the pressure increases with the increase of cutting oxygen flow velocity and momentum, cutting speed will increase. In addition to the purity of the oxygen in the above-mentioned effect of the CNC flame cutting, gas flame cutting process, affecting the final cut quality factors, such as preheating the power of the flame, cutting the metal composition, performance, surface state and the initial temperature. Only integrated a variety of factors to consider in order to make more perfect cutting results.hydraulic hose crimping machine

 Currently on the market CNC cutting machine, the use of biaxial orientation are driven, is the cutting surface in a Cartesian coordinate system provided by the NC system, the X-axis and Y-axis coordinate position torch, complete cutting torch according to the two axes of the number of data changes continuous cutting operation. In frequent daily use, the CNC cutting machine, dual-axis positioning drive is a problem, how do we deal with it? Here we analyze the reasons for failure:

       First of all, we need to rule out whether the NC system, torch-axis coordinate value is a numerical control system, if the coordinate values ??as the eyes of the cutting machine, that the NC system is undoubtedly the brains of the whole cutting machine. If it is determined that the NC system, you need to contact the manufacturer by the manufacturers to provide technical support to the NC system maintenance; to troubleshoot the system, causing the axis deviation may be more concentrated in the mechanical aspects of hardware failure. Hardware failure can be attributed to two major aspects:hydraulic hose cutting machine
  A CNC cutting machine, gea r reducer shaft problems;

  CNC cutting machine reducer and motor connections problems.hydraulic hose machine

    If you encounter the XY axis deviation, I believe the problem can be solved as long as the factors mentioned by the appeal investigation.
    Biaxial-driven applications are usually in order to get a larger load capacity or use large span containing the unloading system, so use the main demand is not focused in the high-speed cutting. With the development of related technologies, the demand for speed and accuracy of machine tools and improve the design of dual-axis drive also began to be used on high-speed machining centers, to suppress the vibration due to the high-speed feed. In conclusion, dual-axis drive applications, the main advantages:
  Suppress vibration at high speed;

  (2) to improve system rigidity, extend screw life;hydraulic machines

  Improve system response.
