"The fastest knife" -laser cutting sheet metal processing applications
2016-08-26
Laser cutting is the rise in recent years and has been thriving in the field of sheet metal cutting, from micron to tens of millimeters thin plate plate, can be perfectly effective cutting. In a sense, laser cutting machine technology has brought a revolution in sheet metal processing. Compared with the traditional cutting, the laser cutting more easy to understand, easy to learn, and in effect the business processing requirements and speed all have an absolute advantage, so believe in the future of the cutting mode selection, laser cutting machine is the trend.
In recent years, laser cutting technology is becoming the manufacturers are "competing to fight Yan" ace in the hole, and its due to the breadth of application, it can be divided into: laser vaporization, laser melting melt cutting, laser cutting and laser oxygen scribing and breaking control four categories. It is worth mentioning that the laser cutting can cut all financial melt meltable material such as metal.
When using a laser to cut stainless steel, most of them will use high-pressure nitrogen injection laser beam coaxial ways to blow away the molten metal and such that the cutting surface will not form any oxide. This is a good method, but higher compared with the conventional oxygen cutting costs. A method can replace the use of compressed air purity nitrogen plant is filtered, which consists of 78% nitrogen. Laser cutting using filtered compressed air or nitrogen than oxygen faster - typically 300ipm to 320ipm, although the need for some equipment, filtration, compressed air, a certain initial investment, but the long-term cost relative "traditional" in terms of the cost of secondary gas or lower. Laser energy is now in a position of the focus, and the use of compressed air to produce a plasma ball on the surface of the metal, the effect is similar to using the power CNC plasma cutting machine cutting effect produced. The effect of plasma transfers heat more efficiently than light.
