A metal laser cutting machine is a kind of mechanical equipment that uses laser technology to manufacture and cut metal. At present, many metal processing manufacturers choose to use laser cutting machines to cut metal.
Metal Laser Cutting Service is an important production process in the industrial construction industry. At present, acetylene, propane and other raw materials are used in the cutting process to improve production efficiency and save energy. A so-called metal cutting machine, also known as a metal laser cutting machine, is the energy released when a laser beam is shone on the surface of a metal workpiece to melt and evaporate the metal workpiece for the purpose of cutting or carving. ****** Fast cutting, not limited to the limit of cutting mode, automatic typesetting saves material, smooth cutting, low processing cost.
The new generation of advanced metal laser cutting system has a good optical mode and precision, the mechanical directly driven cutting head contact plate movement, always maintains the laser focus. The constant cutting speed of the whole working surface is of uniform quality; double track positioning, ball drive, fast speed, high precision, stable movement, good dynamic performance, long service life; machine vertical direction, horizontal movement direction switch, polyurethane anti-collision rod to ensure the safe operation of the machine; the automatic programming system directly generates graphics file processing program, computer simulation graphics processing path, automatic sleeve discharge, improve processing efficiency and material utilization.
Metal laser cutting machine as a new tool, more and more applied in various industries. So how do you use metal laser cutting? How to distinguish metal laser cutting?
First, the energy of a laser is concentrated in a dense beam of light. The beam passes to the working surface and generates enough heat to melt the material, directly removing the molten metal of the high-pressure gas coaxial with the beam, so as to achieve the purpose of cutting. This shows that the cutting process of metal laser cutting machine is basically different from the processing of machine tools.
It uses the laser beam emitted by the laser generator to focus into the high power density laser beam irradiation condition through the external circuit system. The laser heat is absorbed by the workpiece material and the workpiece temperature rises sharply. After reaching the boiling point, the material begins to evaporate and form. When the beam moves compared to the workpiece, the hole ends up creating a slit in the material. The process parameters (cutting speed, laser power, air pressure, etc.) and the slit trajectory are controlled by the numerical control system, and the slag at the slit is blown away by the auxiliary gas at a certain pressure.
In the metal laser cutting process also added suitable for cutting material auxiliary gas. When cutting steel, oxygen is used as an auxiliary gas to produce exothermic chemical reactions with the molten metal to oxidize the material, and it helps blow away the slag in the grid. Nitrogen can be used as an auxiliary gas for metal parts with high machining accuracy. Most organic and inorganic substances can be cut with metal lasers.
