What to do when optical fiber laser cutting machines can't cut through?Many customers encounter this problem in the use of optical fiber laser cutting machine, so what are the causes of this problem?Perfect Laser now summarize to you:1. The plate thickness is greater than machine thread cutting thickness: optical fiber laser cutting machines of different power will have a limit of cutting thickness, if it is beyond the limit thickness,the equipment cutting effect will be not ideal, including the situation that it can't cut through.2. The power of laser decrease: after being used for a long time, the power of fiber laser  will reduce gradually over time, finally lead to the decrease of the cutting ability, also the situaton that it can't cut through will happen.3. The spot debugging is not done: the spot of fiber laser cutting machine is the most important factor that affects the cutting quality , when the spot debugging can not meet the standard, the situation that the machinecan't cut through would happen.4. Optical element pollution: optical components include focusing mirror, the reflector and protective glass, because of bad processing environment for a long time, it is easy to cause the residue on the lens surface, reduce the laser power, leading to the situation that it can not cut through.5. Cutting too fast: the cutting speed too high, missing cut is bound to happen, so that lead to the situation that it can not cut through.300w Fiber Laser Cutting Machine adopts advanced fiber laser generator and ball screw moving system, it can cut and punch different kinds of metal material with high precision and high speed.Since laser is transmitted by fiber, it is no need to maintenance or adjusts the laser optical path. It greatly reduces the machines fault rate and prolongs the working life.Large format cutting area meets the demands of various kinds of metal processing. View Details

Effect of different position on laser cutting 2016-08-05

One of the advantages of laser cutting is that the energy density of the beam is high, so the focal spot diameter is as small as possible in order to produce a tiny slit. If the focal depth of the focusing lens is smaller, the smaller the diameter of the focal spot will be.For high - quality and high - precision cutting, the effective focal depth is also related to the diameter of the lens and the material being cut, so it is very important to control the position of the material surface.Here are three aspects of the following aspects to analyz... One of the advantages of laser cutting is that the energy density of the beam is high, so the focal spot diameter is as small as possible in order to produce a tiny slit. If the focal depth of the focusing lens is smaller, the smaller the diameter of the focal spot will be.For high - quality and high - precision cutting, the effective focal depth is also related to the diameter of the lens and the material being cut, so it is very important to control the position of the material surface.Here are three aspects of the following aspects to analyze cutting focus due to the different materials and requirements of different choices.(I)Cutting focus on the surface of the materialThis way is also known as the 0 focal length, ,commonly used in SPC, SPH, SS41 and other parts of the cutting. When used. the focus of the cutting machine should be selected on the surface of the material. In this mode, the upper and lower surfaces of the upper and lower surfaces are not the same. In general, the cutting surface near the focus is relatively smooth. However, the lower surface of the cutting focus appears to be rough. Therefore, this model should be based on the actual application of the actual application then to decide on the choice of the surface or the lower surface.(II) Cutting focus on the material insideThis way is also known as the focal length. When the material is stainless steel or aluminum plate, often use the model of cutting point in the material inside. But one disadvantage of this method is that the cutting is larger than the cutting point at the surface of the work piece. At the same time, this model needs larger cut air flow, more sufficient temperature , and longer time for cutting an Perforation. So when the material you chose is mainly stainless steel, aluminum or hard material, you should use this way .(III) Cutting focus on the material aboveThis way we are also known as the negative focal length. Because the cutting point is not located at the surface of the material nor the material inside, but it is located in the top of the cutting material. Thus this method is mainly used in the material with high cutting thickness. This approach is focused on the cutting material, mainly because of the need for a large plate. Otherwise, the oxygen of the nozzle is extremely easy to lead to the problem and the result of the cutting temperature is reduced. But one drawback of this approach is that the cutting surface is rough and less suitable for cutting precision. View Details

Since the early 1980s, the automotive industry has been one of the driving forces behind innovative high-power laser applications. This industrial segment has stringent requirements regarding the quality and reliability of beam sources. In conjunction with cutting, welding and marking, lasers offer considerable benefits compared to conventional techniques. Improved flexibility and ease of automation, meet the central requirements of this sector.The first lasers were used to weld simple cylindrical parts, such as the components of an automatic transmission. The use of a CO2 laser minimized distortion allowing highly compact and affordable gear trains. Today, lasers are used to process complete vehicle bodies. Roof seam, door welding, three-dimensional cutting of hydroformed parts, annealing of door springs, marking of day & night panels are only a few examples out of a wide range of applications.Lasers that are used as cutting and welding tools have become indispensable for general machine construction. There is hardly a sector today where lasers are not successfully proving their value, offering a variety of benefits in industrial production. Thanks to clean cut edges, reliable weld seams and flexible guidance systems, high-power lasers have conquered a considerable market share, especially in sheet metal processing.The processing spectrum is manifold: various components are marked flexibly, durably and with changing contents, flat sheets with thicknesses of 25 mm are cut by lasers or gearwheels, injection nozzles, fire extinguisher housings and heat exchangers are welded. Furthermore, lasers are used for the production of tubes and profiles that are cut by lasers or welded thanks to intelligent system solutions. View Details

Wood working lasers are optimally suited for laser engraving and laser cutting wood and timber, such as decorative items, artistic craft-work, souvenirs, Christmas decorations, gifts, architectural models, and for wood inlays. This including materials of plywood, MDF, Balsa Wood, and many other wood types.     Q1: How can wood be cut or engraved with a laser?    Personalization and individualization are often the most important when cutting or engraving wood with the laser. Text or lines are applied to photo frames to increase their value; photographs or even logos can be realized with incredible detail with the laser. Using the laser provides the user with extreme flexibility and the ability to refine the woods in a very high quality.     Q2: Can any type of wood be cut and engraved with the laser?    As you may know, wood is a natural material, the laser user must consider various characteristics, including the density and the resin content when working with wood. Soft wood types, such as Balsa wood, require a lower laser power and can be cut at a higher speed. Hard wood, as an example of dense wood types, on the other hand, requires a higher laser power. When working with MDF, which consists of glued wood fibers, recommends the use of compressed air.     Q3: Does the wood burn during laser cutting?    The laser will produce a temperature increase that is higher than the sublimation temperature of wood. The “suddenly evaporated” wood is visible in the form of smoke escaping at a fast rate. This smoke also transports the introduced heat away from the wood. Consequently, there is only relatively low thermal stress on the material near the cutting clearance. By accurate focusing and selecting the appropriate optics and by supplying compressed air, high-quality cuts can be produced. The cutting edges with their brown color can often be used effectively in the design.     Q4: Do I have to fixate the material on the working surface?    No. The laser does not exert any pressure on the wood during the process; clamping or any other type of fixation is therefore not required. Simply insert the work piece and start the laser process. This saves time and money during the preparation of the material. When milling wood, on the other hand, the boards must be clamped in position and must often be fixated by a vacuum. View Details
