At present, the number of domestic fiber laser cutting machine brands continues to increase, resulting in different prices for fiber laser cutting machines in the market.

  • Laser

At present, the main imported laser brands in the market are IPG, TRUMPF, Enna, SPI, etc. The largest market share is IPG. Domestic brands include Ruike, Chuangxin, JPT, Fibo, etc. And Rui has the largest share. Branch out. Under normal circumstances, there is basically no difference between domestic brands and imported brands of fiber lasers with power below 3000W for cutting the same material. And there is still a difference in high power.

  • Power

The size of the power is an important part of the price of the fiber laser cutting machine. The greater the power, the higher the price and the greater the working efficiency of the product. Therefore, buyers can choose a cost-effective fiber laser cutting machine according to their personal needs and after assessing their production needs.

The price of fiber laser cutting machine is also closely related to the type and material of the product to be cut. Before purchasing a fiber laser cutting machine, the thickness and material of the applicable product should be clarified. So as to comprehensively consider the manufacturers of fiber laser cutting machine. The cutting process, bed process, sheet metal process, assembly process and other process-related issues. The final selection of the appropriate laser cutting machine for cutting products.

  •  Precision and bed

The machining accuracy of the machine tool is an important index to measure the performance of the machine tool. There are many factors that affect the machining accuracy of machine tools, including the accuracy of the machine tool itself, as well as the deformation of the machine tool and the process system, the vibration during processing, the wear of the machine tool, and the wear of the tool. Among the above factors, the accuracy of the machine tool itself is an important factor.

For example, when turning a cylindrical surface on a lathe, the cylindricity is mainly determined by the stability of the rotation axis of the workpiece, the straightness of the tool nose movement trajectory, and the parallelism between the tool nose movement trajectory and the workpiece rotation axis, which is mainly determined by the lathe The movement accuracy of the spindle and the tool post and the position accuracy of the tool post movement trajectory relative to the spindle.

Characters of laser cutting-fiber laser cutting machine advantages-Wendy

cutting effect

Characters of laser cutting-fiber laser cutting machine advantages-Cathy

Character a.

Good cutting quality. You can get quite well cutting quality only by one time cutting. Because of the small laser spot and the high energy density. The kerf of the laser cutting generally be 0.1-0.2 milometer. Width of the heat effective area is small.  Cutting geometry is good. The cross section of the kerf is more regular and rectangular. The cutting surface of laser cutting has no burrs. The surface roughness R can generally reach more than 12.5um. Laser cutting is even used as the last processing step. Generally, you can weld directly without further processing after laser cutting as the good cutting surface, or you can use the components directly.

Character b.

Fast cutting speed. Laser cutting speed is fast. For example, 2 kilowatt, 8 milometer thick carbon steel cutting speed is 1.6 meters/minute. 2 milometer thick stainless steel cutting speed is 3.5 meters/minute. When laser cutting, the heat effective area of the work piece is small. The deformation is extremely small. No need fix by clamp device, so can save the clamp device, also can save the clamping time.

Character c.

Material can be cut ranges width. Compared to flame cutting and plasma cutting, the material types that laser cutting can cut ranges width. Include metal, non-metal, metal based and non-metal based composite material and so on.

Character d.

Suitable for big work piece processing. The mold manufacturing fee of the big work piece is high. Laser cutting don’t need any mold. Besides, laser cutting can avoid the slump formed when the material is punched and sheared, which can greatly reduce company’s production cost.

Character e.

Clean, safe, no-pollution. The laser cutting process has low noise, low vibration and no pollution, which greatly improves the working environment of the operator.

Character f.

Not easy to affacted by electromagnetic interference.

“Small and Beautiful” Laser Cutting Nozzle, Which One Is Right for You?—Winnie

Active Gas Laser Cutting

Energy from the laser beam heats the material (mild steel) to above the ignition temperature in the reactive gas (O2).

Fe+½O2→FeO

Combustion-process Fuels the Burning of Iron Oxide

Once the kerf has been opened, material removal is from a nearly vertical erosion front (thin molten layer). Absorption of laser energy is predominantly at this liquid layer during the cutting processing. The layer loses heat by vaporisation, by ejection of liquid material at the lower surface, by conduction and by melting of solid material as the cut advances. In order to ensure the quality of the workpiece and the efficiency of the process, the selection of the proper conditions is very important, such as laser power, cutting parameters, cutting head and nozzle.

 

 

Striations-The slow cutting speed will cause the local thermal accumulation,which will lead to rough striations even side burns.

The Overview of Laser Cutting Nozzle

The nozzle is very important in laser cutting. Its main purpose is to deliver a gas jet such that the heat generated by the laser beam (and the resulting melt & vapour) is blown away, leaving a clean cut.

If the nozzle is poorly designed (& maintained), the gas jet will not have the required velocity or directional stability to remove the molten material.

Firstly, there are two basic designs: ‘Low Speed’ (gas velocity less than speed of sound) and ‘High Speed’ (velocities around the speed of sound). Secondly, there are many factors that affect nozzle performance nozzles, such as chamber pressure , nozzle diameter, internal shape, so nozzle exit shape and nozzle material.

Low Speed Nozzle VS High Speed Nozzle

Low Speed Nozzle

 

Laval High Speed Nozzle

 

Why high speed LC nozzles?

Some materials such as stainless steel and aluminium alloy are difficult to cut because their molten material is viscous and cannot be easily removed with low gas speeds.

High speed nozzles work on the same principle as a rocket or jet engine exhaust. The gas expands, pressure drops and the gas velocity accelerates to the design velocity at the nozzle throat region and accelerates to the supersonic gas velocity at the nozzle exit. The design velocity is determined by throat area, exit area, gas pressure, atmospheric pressure, nozzle inter shape and nozzle length.

The gas pressure along the axis of the jet can vary a great deal with changing of the stand-off distance in the low speed case and variation in pressure on the work-piece surface will affect the ability of the gas jet to remove molten material at the cut front.

Relationship between Surface Quality and Nozzle

Nozzle temperature: The high temperature of the nozzle will affect the capacitance of the ceramic ring so cause the instable stand-off distance, and which will lead to the uncontrollable cutting quality during the production.

Laser cutting machine daily maintenance points, common work problems and solutions–Winnie

Fiber laser cutting machine is an advance equipment, the price is generally very expensive. Every few tens of millions, but its ultra-fast processing speed, favored by many processing industries. Then, want to make good use of fiber laser cutting machine Performance, what aspects should you pay attention to?  The fiber laser cutting machine also has a lot of places to pay attention to in daily maintenance. Pay attention to the following items to ensure the stable performance of the fiber laser cutting machine!

The maintenance of the laser cutting machine can roughly performe from the following aspects:

Fan cleaning:

The long-term use of the fan in the machine will cause a lot of solid dust to accumulate in the fan, which will make the fan generate a lot of noise, which is also not conducive to exhaust and deodorization. When the suction of the fan is insufficient, the fan must be cleaned.

Replacement of circulating water and tank cleaning:

Before the machine works, make sure that the laser tube is filled with circulating water. The water quality and temperature of the circulating water directly affect the life of the laser tube. Therefore, it is necessary to periodically change the circulating water and clean the water tank. This is usually done once a week.

Lens cleaning:

There will be some mirrors and focusing mirrors on the machine. The laser light is reflected and focused by these lenses and emitted from the laser head. The lens is easily stained with dust or other contaminants, causing laser loss or lens damage. So clean the lenses every day.

When cleaning, pay attention to:

1. The lens should be wiped gently, so as not to damage the surface coating;

2. Handle gently during wiping to prevent falling;

3. Please keep the concave surface down when installing the focusing lens.

Fastening of screws and couplings:

After the motion system works for a period of time, the screws and couplings at the motion joints will loosen, which will affect the smoothness of the mechanical movement. Therefore, during the operation of the machine, observe whether there are abnormal noises or abnormal phenomena in the transmission parts, and find the problems in time Robust and maintenance. At the same time, the machine should use a tool to tighten the screws one by one after a period of time. The first solidification is about one month after the equipment is used.

Rail cleaning:

Guide rails and linear shafts are one of the core components of the equipment, and their functions are to guide and support. In order to ensure the machine has a high processing accuracy, it is require that its guide rails and straight lines have high guiding accuracy and good motion stability.

During the operation of the equipment, due to the large amount of corrosive dust and fumes produce by the workpiece during processing, these fumes and dust have deposite on the surface of the guide rail and linear axis for a long time, which has a great impact on the processing accuracy of the equipment and will Corrosion spots are formed on the surface of the linear axis of the guide rail, which shortens the service life of the equipment. So clean the machine guides every half a month. Turn off the machine before cleaning.

Inspection of light path:

The optical path system of the machine is complete by the reflection of the mirror and the focusing of the focusing lens. There no offset problem in the focusing lens in the optical path, but the three mirrors are fixe by the mechanical part, and the possibility of offset is large.

Although there is usually no offset, it is recommende that users check whether the optical path is normal before each work.
