During the cutting process, only the beam (cutting torch) mobile, bench does not move. In the cutting process, only the table moves the beam (torch) is fixed. Sometimes encounter the need to cut the three-dimensional components of industrial production, the general two-axis, three-axis laser cutting machine can only cut two-dimensional workpiece, this need is equipped with a robotic cutting machine, five-axis machine. Laser punching machine. Over the years, the overseas development of a comprehensive laser cutting and mechanical punching, laser punching machine, this mechanical mode of the complex shape of the workpiece using mechanical methods out of the hole, then use the laser cutting method to cut out the outer edge and require long-distance cut the lines. green laser pointer has no restriction of direction.
Workpiece before cutting its problems that may arise in the feasibility of laser cutting and cutting process should be considered in advance. For example, whether such materials can be laser cut? Where is the difficulty of its cutting? Try cutting the samples? How to achieve the requirements of cutting quality and accuracy? Workpiece cut the benchmark starting point on where? And so on. Many factors that affect the quality of laser cutting, laser cutting is an important advantage of the high degree of control can be implemented on the main factors in the process of cutting the workpiece to fully meet customer requirements, and good repeatability. These main factors of the process parameters of the cutting speed, focus position, the auxiliary gas pressure, laser output power. The size of green laser pointer is 26.5*118mm.
In addition to the four most important variables may have an impact on cutting quality factors including the beam parameters (mode and power, the polarization of the laser beam, laser beam focusing, pulse beam) and the workpiece characteristics (surface reflectivity, surface state), as well as other factors of the cutting torch and nozzle, outside the optical system, the workpiece fixed. Laser cutting basics. The main features of laser cutting. Laser cutting kerf narrow, small deformation of the workpiece. The laser beam is focused into a small spot, the focus at high power density. At this time, the beam input of heat is far more than the reflective material, conduction or diffusion part, the material is quickly heated to the vaporization of the degree of evaporation of pore formation. The output power of green laser pointer is 50mW.
With the relative linear movement of the beam and materials, so that the holes continuous width is very narrow kerf. Trimming a small heat-affected, the basic deformation of the workpiece. The cutting process also add a secondary vapor suitable with the material being cut. Steel cutting oxygen exothermic chemical reaction as an auxiliary vapor with the molten metal oxide materials, while helping to blow away the slag within the slotted. Cutting polypropylene plastics to use compressed air, cotton, paper, flammable materials, cutting the use of inert vapor. But also cooling of the secondary vapor into the nozzle to focus the lens, to prevent the smoke into the lens holder pollution lenses and the lens overheating. Most organic and inorganic materials using laser cutting. No drive is needed to be installed for green laser.
