  • Five trends about fiber laser cutting -Erin

    Five trends about fiber laser cutting -Erin

    Here share five trends about fiber laser cutting:

    1. High power can improve performance and throughput.

    High power fiber laser cutting technology has been increasing year by year. These high-power lasers provide greater cutting range, faster cutting speeds, and improved part edge quality while increasing performance and yield. High power can usually cut thicker materials, but the larger cutting range is only one of the advantages of high power laser cutting. Faster cutting speeds also increase yield. Since the introduction of fiber lasers, improving edge quality has been the focus. CO2 lasers provide excellent edge quality, and solid-state laser technology has been working to achieve this. As fiber lasers move to higher power levels, the edge quality is significantly smoother and smoother, and is now more similar to CO2 lasers. High-power lasers can also perform more nitrogen and air cutting in thicker mild steel. Nitrogen and air cutting can provide faster cutting speeds, and can also be paint directly after cleaning, requiring secondary processing of parts.

    2. New nozzle technology reduces gas consumption and improves cutting speed.

    There are various nozzle designs on the market. Some can increase cutting speed and reduce gas consumption, while others can provide reliable cutting performance across the entire cutting range. Each nozzle design is suitable for a specific cutting application, and each of these nozzles offers different advantages depending on the thickness of the material you are processing.

    3. High-pressure gas cutting reduces parts costs Traditionally, the air system provides a pressure of about 150 psi.

    Under this limited pressure, the cutting capacity is relatively low. Due to insufficient power to use air, there are now high pressure systems of 400 to 500 psi, which is usually equal to the pressure of a nitrogen bulk tank. High-pressure compressed air is particularly suitable for aluminum cutting. Other materials can also be cut, such as stainless steel, but the cutting edges of the part may lose their luster or become gray. The edge quality of air-cut mild steel is also slightly worse.

    4. Laser automation increases flexibility and productivity.

    For workers, loading and unloading work can be very laborious, and the use of automatic loading and unloading devices and automatic control systems can greatly reduce the physical nature of the laser operator’s work. There is no doubt that automation can increase efficiency. It’s time to embrace the future and begin the transition to a more automated workforce and work environment. Many other components can  add to the automation system, such as conveyors, labelers, and more. Different automation systems can be customized according to requirements. Automation allows manufacturers to increase productivity without adding machines or personnel.

    5. Pipe cutting can meet the growing demand for structural steel utilization.

    With the widespread application of residential and non-residential buildings, structural steel has become more and more popular. Thanks to advanced technology, buildings can be moved vertically faster by using pipes. Because it is more environmentally friendly, pipes are also the first choice. Compared with other structural materials, the metal recovery rate reaches 90%, making it more “green”. Why do we have to cut tubes with lasers? Due to faster cutting speeds, high-precision cutting and increased downstream manufacturing efficiency, lasers are the ideal solution for cutting pipes and structural materials.

    Fiber laser Cutting speed&effect

    Fiber laser cutting speed&effect.

    We all know that speed and quality are often inversely proportional. In pursuit of speed, quality will be reduced. The pursuit of quality will affect speed. So, what effect does the cutting speed of metal laser cutting machine have on cutting quality? Let’s take a look.

    The selection of the appropriate cutting speed for metal laser cutting machine is also very important. The optimal cutting speed range can be selected according to the equipment description or determined by experiment. Due to the different thickness of the material, the material is different, the melting point is high, and the thermal conductivity is The rate of change and the surface tension after melting, the cutting speed also changes accordingly.

    The effect of cutting speed on the quality of the cut.

    1. Appropriate improvement of cutting speed can improve the quality of the incision, that is, the slit is slightly narrowed, the surface of the incision is flatter, and the deformation can be reduced.

    2. The cutting speed is too fast, so that the cutting line energy is lower than the required amount. The jet in the slit cannot quickly blow off the melted cutting melt to form a large rear drag, accompanied by the slit slag, the slit The surface quality is degraded.

    3. When the cutting speed is too low, since the cutting point is the anode of the plasma arc, in order to maintain the stability of the arc itself, the anode spot or the anode region must find a place of conduction current near the slit near the arc, and at the same time, it will flow toward the jet. More heat is transferred radially, so that the slit is widened, and the molten material on both sides of the slit gathers and solidifies at the bottom edge, forming a dross that is difficult to clean, and the upper edge of the slit is rounded due to excessive melting by heating.

    4. When the speed is extremely low, the arc will even go out because the slit is too wide.

  • Fiber laser metal cutting machine running cost-Wendy

    Fiber laser metal cutting machine running cost. This machine Machine have become very popular in most metal cutting factory. Several years ago, only some big metal cutting factory use fiber laser cutting machine as it is very expensive machine. Recently years, more and more small factory use fiber laser cutter replace old cutting tools. As machine cost is much more lower, may be only 30~60%. Additional, fiber laser cutter’s running cost is the lowest.

    Of course, although fiber laser cutter have very low running cost, but it is not mean no consumable parts.

    Fiber Laser Cutting Machine consumable

    1. Electric Power

    Electric power is necessary for all machine. Laser cutting machine’s electric power cost total include three parts, include laser source, water chillier and servo motor.

    1000w laser cutting machine for reference.

    fiber laser’s photoelectric conversion is 25%, which is the highest in all laser machine. One set 1kw laser source will cost 4kw/h. 1000w fiber laser machine’s water chillier need use 3kw/h. Servo motor and machine bed parts total need about 4kw/h. So if one 1kw laser machine running in full power its electric power cost is about 11kw/h. Actually one machine’s real cost only use 60% power as these parts is not running always. In this case, its real cost is about 6.6kw/h. But one set 1000w co2 laser cutting machine’s power cost will be several times.

    2. Auxiliary Gas

    Usually we use O2 gas when cut mild steel and N2 gas for other material, such as stainless steel, aluminum and brass. For example, when we cut 1mm stainless steel, it need about 12kg/hour N2. When we cut 5mm mild steel, it need about 9kg/hour.

    3. Quick wear parts

    Fiber laser cutting machine’s quick wear parts all on laser cutting machine, include protective lens, focus lens, nozzle and ceramic ring. Protective lens and nozzle’s lifetime is about 1 month/piece. Focus lens’s lifetime is about 3 months/piece.  ceramic ring’s lifetime is about 1 year or more.

    Except above parts, fiber laser cutting machine nearly have no other consumable parts. Compared with other cutting tools, its cost is very very low. So more and more people select fiber laser cutter with its price’s decline.

  • The difference between fiber laser cutting machine and CNC plasma cutting machine-Vicky

    Fiber laser cutting machine 

    In fact, the energy release is that when the laser beam irradiat onto the surface of the workpiece to melt. And evaporate the workpiece to achieve the purpose of cutting and engraving. It has high precision and fast cutting, not limited to cutting pattern limitation, automatic typesetting saves material, and cuts. Smoothing, low processing costs, etc., will gradually improve or replace the traditional cutting process equipment.

    As a new type of tool, laser cutting machine equipment is more and more mature in various industries, including high-precision laser cutting machine, precious metal fiber laser cutting machine, 3D robot fiber laser cutting machine, laser spot welding machine, etc. So, the energy of the laser concentrat into a high-density beam in the form of light. The beam is transmitted to the working surface, generating enough heat to melt the material, and the high-pressure gas coaxial with the beam directly removes the molten metal, thereby achieving the purpose of cutting. So, it shows that the laser cutting process is essentially different from the machining of the machine tool.

    The CNC plasma cutting machine .The CNC plasma cutting machine is a new type of thermal cutting equipment. So, Its working principle is to use a high-temperature plasma arc heat to partially melt the metal at the workpiece incision. and to remove the molten metal by high-speed plasma momentum to form a slit.

    Laser cutting uses a high power density laser beam to scan the surface of the material. Heating the material to thousands to tens of degrees Celsius in a very short time. Melting or vaporizing the material, and then melting or vaporizing the material from the slit with a high pressure gas. Blow away in the middle to achieve the purpose of cutting materials.

    Fiber laser cutting machine maintenance instructions

    Fiber laser cutting machine maintenance instructions

    Laser cutting machines are high-tech equipment in mechanical equipment. They are expensive at the time of purchase.

    In order to ensure the normal use of the laser cutting machine, the equipment must  maintain. Mastering the operation of the equipment, you can easily cut out the effect of the workpiece you want and extend the life of the laser cutting equipment. The following are some daily use and maintenance tips for Xintian Laser Finishing for your reference:

    First, let the steel strip stay tight at all times.

    The steel belt plays an important role in the transmission of the laser cutting machine. If the steel strip is not tight when the equipment is running, the cut articles are easily pull out of the track. And the steel strip may slip down, which is a danger to the equipment to the operator.

    Second, always check the angle of the tool

    In the process of using the fiber laser cutting machine, the cutting of different materials should adjust. In additional , the laser cutting head is one of the important accessories of the fiber optic machine. It is relate to the cutting effect. If it is used for a long time or improperly used, the laser head may be deviated. In the case of insufficient precision of the material being cut or attending the skewed situation, it is necessary to adjust it in time.

    If the angle of the cutting head, the sample cut by the equipment will not pass. And the unqualified product will increase, thereby increasing the production cost.

    Again, often sweeping the machine

    In the general processing plant, the use of fiber laser cutting machine should pay attention to cleaning dust, dust will make our equipment run simmer, increase the friction between the parts, and increase the loss. Frequent cleaning of the fiber laser cutting machine helps our cutting machines maintain accuracy.

    Finally, parts must be treated with lubricating oil frequently

    We need to lubricate the racks, rails, and parts of many cutters from time to time. So that they can make the gears bite in operation. So, the mechanical operation will  in the normal running track, and the precision of the cut products will  high.

  • Important Safety Precautions When Using a Fiber Laser Cutting Machine-lisa

    Important Safety Precautions When Using a Fiber Laser Cutting Machine

    fiber laser metal cutter
    fiber laser metal cutter

    During operation and maintenance of a Fiber Laser Cutting machine. It is important to remember some basic safety precautions as well as some simple things to avoid. Fiber Laser cutting systems are advancing systems of cutting technology  in fabricating shops throughout the world. And they require an advanced approach to maintenance and care. With proper maintenance, and an eye to safety, you can keep your fiber laser machine cutting for years to come.

    1. Learn Your Machine

      – First off know your machine. Read and understand the maintenance manual for the machine, chiller, power source, dust collector. And any other components and accessories connected to or running from the Laser Cutting system.

    2. Know The Source

      – It’s important to know that many items have their own power source. And although you may have shut off the machines power, the chiller may still electrified. Know where all circuit cut-off breakers are and how to properly lock them in a safe position.

    3. Know Its Done

      – Make sure the fiber laser machine has completed all motion before attempting any kind of maintenance. As sometimes there are pauses in a program, such as shuttle table motions that may not be visible.

    4. Don’t Bypass The Doors!

      – When setting up and during normal operation it is very easy for operators to want to bypass the door switches in order to operate the machine with the front or loading doors open. If these door locks are by pass on your fiber laser machine, your operator and surrounding staff will be expose to not only the Class-1 Fiber Laser Light (which can blind!) . But possible loose parts ejected from the machine during a rapid move. Further, anyone accidentally entering the motion zone can be pinch or crush as the nature of fiber laser cutting systems is to process material very fast and thus have exceedingly high rapid speeds.

    5. Wear Your Safety Glasses

      – Never before in laser cutting systems has the light source been so intense and powerful then in fiber laser cutting machines. These lasers are typically guarded by solid cabin designs. And expensive green glass protecting the operator and surrounding work area from flashes and eye burn. When maintaining your fiber laser make sure you take precautions by wearing your Class-1 Laser Light approved safety glasses as well as any other recommended safety gear.

    6. Chill Out

      – Maintain your chiller properly by checking fans, fluid levels in it and ensuring the filters are clean and clear per your manufacturer’s recommendation. It is also imperative to ensure the chiller is running and cooling prior to turning the solid state fiber laser resonator on, as a cooling source must be in place.  These fiber laser power sources/resonators generate an enormous amount of heat during their normal operation that must be remove by the chilling process. A dirty or damaged chiller can cost tens of thousands in repairs to a damaged fiber laser resonator if not properly maintained.

    7. Steady Hands

      – When maintaining components of the fiber laser do not mishandle or drop them. There are very finely tuned and aligned components including optics within the laser system that can be easily damaged or by an inadvertent drop. Use an extra precaution when maintaining these sensitive components.

    8. Keep it Straight – Although the fiber optic cable is flexible by design, it is not meant to be wound tightly or coiled up like an old extension cord. Remember that inside the shielded larger “cord” like cable is a glass optic that can be fractured or broken. Which will greatly affect your fiber laser machines cutting performance. Also these cables require special equipment and a clean environment to be replaced.
    9. Don’t Remove It!

      – Never remove the Fiber cable from the cutting head or the Laser power source. These areas are very suspect to even the slightest bit of dust and therefore should only be disassembled by technician with the proper tools to maintain the head and cable connections cleanliness.

    10. Clear The Area

      – Make sure the area is clear around the machine when operating it and the shuttle table or loading system. In some cases it is easy for workers to slip inside light guard protected areas during non operation. This be in a hazardous zone, unprotected when these components are then put into action.

    If you follow these safety precautions , your fiber laser cutting system can produce great quality parts for years to come. Although these systems require far less maintenance, a few simple steps can avoid any preventable problems
