Shallow theory of the development of laser metal cutting machine

Laser cutting is a kind of high energy density control good out of contact for processing. It will be focused laser beam into small diameter is less than 0. 1 mm spot, the focus of power density can be more than 107 w ~ 108 w/M2, illumination material quickly heated to the evaporation temperature, evaporation are formed. Along with the relative linear beam and mobile, make holes formed continuous width is about 0. Kerf width of 1 mm. Also added when cutting and cut materials that meet the needs of auxiliary gas, to speed up the process of melting, blow away the slag material or protect the kerf is oxidation. Many metal materials, no matter what kind of hardness, it has no deformation can use laser to cut. Most organic and inorganic materials can use laser cutting. Commonly used engineering materials, in addition to copper, including carbon steel, stainless steel, alloy steel, aluminium and aluminium alloy, titanium and titanium alloy, and most of the nickel alloy, such as laser cutting can be implemented. We can through the metal laser cutting machine and plasma cutting machine, and some traditional cutting way to do some comparison: 1. Business parthers kerf narrow metal laser cutting machine, small heat affected zone and local deformation of workpiece, no mechanical deformation. 2. Is a kind of controllable good out of contact for processing. No tool wear, any material hardness ( Including non-metallic) Can be cut. 3. Business parthers metal laser cutting machine has extensive adaptability and flexibility, ease of automation, with unlimited profile cutting ability. 4. Compared with the traditional way of plate cutting, laser cutting has obvious advantages. Its cutting speed, high production efficiency; Good cutting quality, narrow kerf width; Good adaptability to materials, no tool wear; Whether simple or complex parts, can use laser rapid forming a precision cutting; A high degree of automation, simple operation, low labor intensity, no pollution; Lower the production cost and good economic benefit; The effective of this technology life cycle is long.
5. Laser cutting compared with the conventional processing methods, also has obvious advantages. In hot cutting method, oxygen combustion ( Such as acetylene) Cutting and plasma cutting can't like a laser beam focused energy in a small area, as a result, incision width and heat affected zone and the obvious deformation. Oxygen can burn small cutting equipment, less investment, can cut of 1 m thick steel plate, is very flexible cutting tool, mainly used for cutting low carbon steel. But because of its large heat affected zone, low cutting speed, the incision is indented, and twists and turns. Therefore, it is seldom use for cutting below 20 mm thickness and the requirement of precise size of the material. Plasma cutting and laser cutting speed, significantly higher than that of acetylene flame cutting. But the cutting energy is low, trimming at the top of the round head shaped, trimming waveform significantly. In operation, prevent the ultraviolet radiation produced by the arc to harm to the operator.
