The Difference Between Laser Cutting and Traditional Processing from htpow laser's blog

With the rapid development of sheet metal processing technology, processing technology is also changing, to the sheet metal processing has brought many revolutionary ideas. As a traditional sheet metal cutting equipment, are: CNC shear bed, punch, flame cutting, plasma cutting, high pressure water cutting.

These devices in the market occupies a considerable market share, one of them familiar, two cheap, although they are relative to the most powerful laser cutting and other modern technology is very obvious disadvantage, but they also have their own unique advantages. CNC shearing machine because it is mainly straight cut, although the knife can cut up to 4 meters of the plate, but it can only be used only in the need for straight-cut sheet metal processing. Generally used in the plate after the flat cut, etc. only need to cut the industry in a straight line.

High pressure water cutting is the use of high-speed water jet cutting of sheet metal doped corundum implementation, it almost no restrictions on the material, the cutting thickness is almost up to 100mm or more, easy to burst with Thermal Ceramics and glass cutting material can be cut, such as copper and aluminum can be cut by laser reflection materials and laser cutting water jet, there is a greater obstacle. The disadvantage of water cutting is that the processing speed is too slow, too dirty, not environmentally friendly, and consumables are also higher.

Laser cutting is a process revolution of sheet metal processing, and it is a machining center in sheet metal processing". Laser cutting has a high degree of flexibility, cutting speed, high production efficiency, short product cycle, and has won a wide market for customers. Laser cutting and no cutting force, no deformation; no tool wear material, good adaptability; whether it is simple or complex parts, can be cut with a precision of blue laser pointer rapid forming; the narrow kerf, good cutting quality, high degree of automation, simple operation, low labor intensity, no pollution; can realize automatic cutting like, nesting, improve material utilization, low production cost, good economic benefit. The effective life of the technology, at present the ultra sheet 2 mm is mostly used in laser cutting, many foreign experts agreed that the next 30-40 years is the golden period of development of laser processing technology (is the development direction of sheet metal processing).

Cutting accuracy is the first element to judge the quality of laser cutting machine. The four factors that affect the cutting accuracy of a laser cutting machine are the size of the laser agglomeration of the laser generator. If the spot is very small after the gathering, the cutting accuracy is very high, if the gap after cutting is also very small. It shows that the precision of 300mw laser pointer cutting machine is very high, the quality is very high. But the laser beam emitted by the laser cone, so cut out the gap is also cone. Under such conditions, the greater the thickness of the workpiece, the accuracy will be lower, so the greater the gap.

Accuracy of the workbench. If the precision of the table is very high, the accuracy of the cutting is improved. So the precision of the workbench is also a very important factor in measuring the accuracy of the laser generator. The laser beam is condensed into a cone. When cutting, the laser beam is tapered down, then if the thickness of the workpiece is very large cutting, cutting the accuracy will be reduced, then cut out the gap will be very large. Cutting the different materials, will also affect the accuracy of 100mw laser pointer cutting machine. In the same circumstances, cutting stainless steel and cutting aluminum its accuracy will be very different, stainless steel cutting accuracy will be higher, and the section will be smooth.
