The way of CNC cutting machine is divided into cold cutting and hot cutting. Today, I want to introduce to you what are the hot cutting methods of CNC cutting, including CNC flame cutting, CNC plasma cutting and CNC laser cutting. On the whole, they have their own characteristics.
CNC flame cutting machine: due to the influence of air pressure, cutting nozzle height, preheating time and other factors, the overall cutting material deformation scale is large, which can not meet the needs of high-precision cutting, and the cutting speed is low. At the same time, due to preheating before cutting, it takes time, which is difficult to adapt to the needs of unmanned operation.
CNC plasma cutting machine: plasma cutting has the characteristics of fast cutting speed and wide range. It is suitable for cutting low thickness metal plates and a variety of non-metallic materials. The maximum cutting speed can reach 10 m / min, which is 5 times of flame cutting. Underwater cutting can eliminate the noise, dust, harmful gas and arc generated during cutting, which is conducive to environmental requirements.
CNC laser cutting machine: high precision, fast speed, small heat affected area, not easy to deform. The cutting seam is flat and beautiful, without post-processing.
In general, NC flame cutting and NC plasma cutting technology are high-tech integrated with NC technology, computer software and hardware technology, plasma cutting technology and precision machinery technology. The development of CNC cutting can completely change the equipment level of domestic hot cutting industry, reverse the current situation of low efficiency, poor quality, high labor intensity, low utilization rate of materials, and poor environment, and narrow the gap with foreign advanced countries. At the same time, the development of CNC cutting technology can drive related fields and disciplines to reach the international advanced level, and drive the rapid development of national industry.
