What Is The Bright Surface Cutting Process Of Laser Cutting Machine

As a common material in life, carbon steel is widely used in rail transit, construction, bridge, engineering machinery, electrical manufacturing, vehicle and other industries by virtue of its high strength, good wear resistance, excellent technological performance and other characteristics. In metal processing, laser cutting carbon steel occupies a very important position, especially through the use of high power laser cutting, burr free cutting, bright cutting and other advanced technology, can obtain high-quality precision workpiece, to meet the welding, surface treatment and other secondary processing requirements.This paper introduces the bright surface cutting technology, which is mainly used in the optical fiber laser cutting machine. The cutting machine using this technology can produce the finished product without burr and bright section in the process of processing materials, and improve the efficiency.Bright surface cutting is a process of cutting carbon steel with oxygen, mainly used for cutting medium thickness carbon steel. Too thin carbon steel plate directly with oxygen cutting, it is difficult to achieve the effect of bright surface cutting, while too thick carbon steel plate needs to use a larger nozzle to cut, to ensure the gas flow and focus height, so can not achieve bright surface cutting.The purpose of bright surface cutting is to require a very bright cutting section, and to achieve this effect, the necessary cutting conditions must be met: the use of a smaller nozzle, to ensure the density of the air; Use less air pressure to prevent excess oxygen to avoid cross section overburn; Use faster cutting speeds; Use high focal point, the higher the focal point, the larger the slit, the better the exhaust effect.Laser cutting machine of high power and high speed bright surface cutting technology, that is, under sufficient power, the use of small nozzle, small air pressure, with high power laser high-speed cutting of different thickness of carbon steel plate, in order to obtain smooth cutting section and smaller taper processing. Smooth section for customers to facilitate subsequent processing; At the same time, the taper can be basically controlled below 0.2mm on both sides, which can better meet the requirements of customers in some high-precision processing industries.The bright surface cutting technology of laser cutting machine, which is mainly used in optical fiber laser cutting machine, can produce finished products without burr and with bright section in the process of processing materials, and improve the efficiency.Bright surface cutting is a process of cutting carbon steel with oxygen, mainly used for cutting medium thickness carbon steel. Too thin carbon steel plate directly with oxygen cutting, it is difficult to achieve the effect of bright surface cutting, while too thick carbon steel plate needs to use a larger nozzle to cut, to ensure the gas flow and focus height, so can not achieve bright surface cutting.Then how to achieve the laser cutting machine fast and good carbon steel bright surface cutting? The following three cutting conditions must be met:Small nozzle: double-layer nozzle, between 1.0-2.0mm;High power: the higher the power, the higher the limit thickness of bright surface of carbon steel can be cut, and the higher the efficiency will be.Atmospheric pressure: mostly 0.6-1.2MPaIn practice, not only need to meet these conditions, but also need professional debugging, in order to achieve a stable and consistent effect.
