1, cutting smooth, no stripes, no brittle fracture; Laser Cutter high-speed cutting thick plate, molten metal will not appear in the vertical laser beam under the incision, but will be in the laser beam behind the spray. As a result, the curved lines formed at the edge of the cutting, the veins tightly followed the moving laser beam, in order to correct the problem, the cutting process at the end of the lower feed rate, you can greatly eliminate the line.
2. Narrow kerf Width This is mainly related to the diameter of laser beam spot; Laser Cutter incision width generally does not affect the cutting quality, only in the part of the formation of a particularly precise contour, cutting width is important, this is because the cutting width determines the profile of the smallest internal, when the thickness of the sheet increases, The cutting width also increases. So to ensure the same high accuracy, regardless of the width of the incision, the workpiece in the laser cutting machine processing area should be constant.
3, cut the vertical degree of good, heat affected area small; In general, Metal laser Cutting
Machine is mainly concentrated in the processing of materials below 5MM, its cross-section verticality may not be the most important factor, but for high-power laser cutting, when processing material thickness of more than 10mm, cutting edge of the vertical degree of importance. As far away from the focus, the laser beam becomes divergent, and the cutting is widened toward the top or bottom according to the position of the focus. The cutting edge deviates from the vertical line a few millimeters, the edge is perpendicular, the cutting quality is higher.
4, no material combustion, no melting layer formation, no large slag; the slag of metal laser NC cutting machine is mainly manifested in deposition and cross section Burr, in which material deposition is caused by laser cutting in the surface of the workpiece before the beginning of the melting of a special oil-containing liquid. Gasification and various materials do not use the customer to blow the cut with the wind, but the upward or downward discharge will also form deposition on the surface. and the formation of burrs to determine the quality of laser cutting a very important factor, because the burr removal requires extra work, so the severity of the burr and how much can be intuitive to judge the quality of cutting.
5, the surface roughness is the key to measure the surface quality of laser cutting. In fact, for Laser Cutter, cutting section lines and roughness directly have direct contact, often poor cross-section of the cutting performance will lead to a higher degree of roughness, but considering that two different effects in the cause of different, generally we analyze metal laser CNC cutting machine processing quality, is still separate to do analysis. Laser cutting cross-section will form vertical lines, the depth of the grain determines the cutting surface roughness, the lighter the grain, the more smooth cutting section. Roughness not only affects the appearance of the edge, but also affects the friction characteristics, in most cases, the need to reduce the roughness, so the lighter the grain, the higher the cutting quality.
