Laser Processing VS Traditional Processing

According to the consumption analysis ofChina's steel industry, the main application industries of steel are construction,machinery, automobiles, and energy, followed by shipbuilding and homeappliances. Most of the plates used in these industries are medium-thickplates.

Traditional mediumthick plates are processed by plasma cutting, flame cutting,water cutting, wire cutting and other processing methods, but there are someproblems such as plasma cannot cut small holes, and poor dimensional accuracy,large thermal impact, cannot cutting small parts, wide weld seam, waste ofmaterials. Flame cutting can only cut carbon steel, not non-ferrous metals, andthe cutting speed is slow. Water cutting has large pollution to water quality.Wire cutting speed is slow and consumables are large. The wear of punchgrinding tools is large, and the cost of mold opening is high.

Traditional processing

In addition to the unique advantages of 10,000 watt-level laser equipment incutting thick plates, its ability to process high precision parts is alsoextremely powerful. For the same gear workpiece (the parts in the followingfigure as an example), the high temperature generated during plasma cuttingwill make the gear sharp corners dull, the cutting surface is rough, theaccuracy is low, and need to use a milling machine to refinish the roundedgears into sharp gears.

The 10,000 wattlevel laser cutting can cut sharp corners at one time, and thesection is smooth which can meet the high precision requirements of aerospace,power equipment, petroleum equipment, automobile manufacturing and moreindustries.

Sample: 500mm diameter gear, 12mmthickness, carbon steel, sharp corner R1mm, 42 sharp corners

For complex graphics, traditional processing methods cannot be completed at onetime, requiring multiple equipment and processes to combine, but the effect isnot satisfactory. However, the flexible laser process can process any graphicswith one device, the speed and effect are beyond traditional processingmethods.

Take the thick metal curtain wall graphics, (the workpiece in the followingfigure as an example) to produce 10-25mm aluminum curtain walls and windowgrilles, the traditional processing method requires the combination of anengraving machine and wire cutting to complete. The engraving machine cannotmake sharp corners, and the cost of wire cutting is high, the efficiency isextremely low, the size is limited. If we use 10,000-watt laser for processing,it can be completed by one device at a time, with fast speed, low cost, goodsurface finish, and it can also process a variety of super large complexpatterns.

Sample: Aluminum window grille, 12mm,irregular pattern

Case 3: Throughhole disc
Application industry: petroleum, natural gas, metallurgy

Traditional processing technology requires the use of molds and tools to assistin processing, which limits the processing of some graphics. If the graphicsdata changes, the mold needs to be remade. The cost of the mold is high, themodification time is long, and cannot be formed at one time. Laser processinghas high flexibility and can process any graphics, the product design can bemodified at any time according to customer needs, and the processing quality ishigh.

For small holes, (the workpiece in thefollowing figure as an example) the minimum diameter of the plasma cuttingaperture can only be approximately equal to the thickness of the processedplate, that is, a 25mm thick steel plate can only be processed with an aperturegreater than or equal to 25mm. For 10,000 watt-level laser cutting, the minimumdiameter of the processing aperture can reach 20% of the thickness of theprocessed plate, that is, a 25mm thick steel plate can process a 5mm aperture,and it is possible to cut different apertures on the thick metal at one time.

The 10,000 wattlevel laser technologydeveloped and promoted by Maxphotonics has simplified the operation. Traditionalprocessing requires multiple people and multiple types of equipment to completeprocessing needs. The 10,000 watt-level laser processing can be completed byone person and one device. This is the best representative of contemporaryadvanced productivity.
