What are the advantages of laser cutting compared with traditional CNC in sheet metal processing
With the application of laser cutting machine, Kunshan sheet metal processing technology has thus been rapid growth, and has brought revolutionary ideas to Kunshan sheet metal processing. As a traditional sheet metal cutting equipment deployment, it is important to mainly deploy CNC setting equipment, including shearing machine, punching machine, flame cutting, plasma cutting, high pressure water cutting and so on, so what is the advantage of laser cutting machine compared with it?
CNC shearing machine because of its importance is straight cutting, although it can cut up to 4 meters of sheet metal with a knife, but it can only be used in sheet metal processing that is only necessary for straight cutting. The same is usually used in industries where straight cutting is only necessary after cutting the plate flat.
CNC punching machine has more mobility in curve processing, a punching machine can have one or more sets of square, round or other special requirements of the punch, you can process some specific sheet metal workpiece at a time, the most common is the chassis cabinet industry, they require the processing technology is the most important straight line, square hole, round hole and other cutting, the pattern is relatively simple and firm. Its advantage is the simple graphics and sheet processing speed is fast, the disadvantage is the ability to punch thick steel plate is limited, even if it can punch the workpiece appearance has collapsed, the cost of mold, mold opening cycle is long, high use, flexibility level is not high.
Flame cutting as the original traditional cutting method due to its low investment, in the past, the processing quality requirements are not high, and when the requirements are too high, a machining process can be handled, and the market volume is very large. Today it is used to cut thick steel plates over 40mm. Its disadvantage is that the slit is too wide when cutting, the thermal deformation is too large, the waste of material, and the processing rate is too slow, so it has to be roughed.
Plasma cutting and fine plasma cutting are similar to flame cutting, the heat affected zone is too large, the accuracy is much larger than the flame cutting, and the speed is also a number of pentium, which has become the main force of plate processing. The disadvantage is that the thermal deformation is too large when cutting the thin steel plate, the slope is also large, and the consumer products are more expensive when the accuracy is high.
High pressure water cutting is the use of high-speed water jet doped emery experiment on sheet metal cutting, it is almost no limit to the material, the thickness of the cutting is almost up to 100mm or more, the ceramic, glass and other hot cutting when easy to burst materials can also be cut, copper, aluminum and other laser high reflection material water knife can be cut, and laser cutting has a large stagnation. The disadvantage of water cutting is that the processing rate is too slow, too dirty, not environmentally friendly, and the efficient products are also high.
Laser cutting is a technological revolution in sheet metal processing, and it is the "processing center" in sheet metal processing. Laser cutting flexibility level is high, cutting rate is fast, production compliance is high, product production cycle is short, for customers to win the market throughout. Laser cutting without cutting force, processing without deformation; No tool wear, good material compliance; Whether it is simple or large parts, it can be cut with a fine rapid forming laser; The slit is narrow, the cutting quality is good, the active level is high, the operation is light, the labor intensity is low, there is no pollution; It can realize cutting active layout and nesting, improve the utilization rate of materials, low production cost and good economic benefits. The useful life of the skill is long, and now most of the 2mm plates in the overseas ocean accept laser cutting, and many overseas experts equally think that the next 30-40 years is the golden age of laser processing skills.
