Laser cutting under the impact of the traditional sheet metal processing and advantage?

The traditional sheet metal cutting equipment equipment has a considerable market share in the market, in addition to their well known reason, mainly is the price is cheap.Although they are relative to modern technology, such as laser cutting, disadvantage is obvious, but they also have their own unique advantages.CNC shearing machine CNC shearing machines due to its main is linear cutting, although the board that can cut one knife for up to 4 meters, but it can only be used on only need linear cutting sheet metal processing.Commonly used in plate kaiping, after cutting only need linear cutting in the industry.Punch press have more flexibility in curve machining, a punch can be one or more sets of punch, round, or other special requirements, can work out some specific sheet metal artifacts, is one of the most common chassis cabinets industry, they asked for the processing technology of main is linear, square hole, round hole cutting, such as fixed pattern is relatively simple.Its advantage is to simple graphics and plate processing speed is fast, the disadvantage is that when strong thick steel plate ability is limited, even can flush the surface subsidence, mold, mold development cycle is long, high cost, flexible degree is not high.Abroad more than 2 mm steel plate cutting processing is generally use more modern laser cutting, instead of using a punch, a thick plate punching and shearing surface quality is not high, when the second plate need larger tonnage punch, waste of resources, three blunt thick steel plate when the noise is too big, is not conducive to environmental protection.Flame cutting flame cutting as the original traditional way of cutting because of its low investment, in the past for machining quality is not high, when asked too much to add a machining process can be solved, the market’s is very big.Now it is mainly used for cutting more than 40 mm thick steel plate.Its disadvantage is that the thermal deformation is too large, cutting the slot is too wide, waste materials, moreover the processing speed too slow, only suitable for rough machining.Plasma cutting, plasma cutting and fine plasma cutting and flame cutting, heat affected zone is too big, the precision is much larger than the flame cutting, speed also have an order of magnitude of leap, become the main force of the medium plate processing.Domestic top fine CNC plasma cutting machine cutting precision of the actual on-line has reached the lower limit of laser cutting, cutting was 22 mm carbon steel sheet at a speed of more than 2 meters per minute, and the cutting face smooth level off, the slope of the best can be controlled within 1.5 degrees, the thermal deformation in cutting thin plate is weakness is too big, slope is bigger also, powerless when high precision requirements, consumables are more expensive.High pressure water cutting high pressure water cutting is using high speed water jet doped silicon carbide in the practice of sheet metal cutting, it is almost no limit of material, the thickness of the cutting is almost can reach more than 100 mm and for ceramics, glass and so on easy to burst when using a thermal cutting material can also be cut, high reflection for laser materials such as copper, aluminum water knife can be cut, and laser cutting has a bigger obstacle.The shortcomings of water cut is processing speed too slow, too dirty, not environmental protection, consumables is higher also.Laser cutting, laser cutting is a technology revolution, sheet metal processing of sheet metal processing & other;Machining center & throughout;.Laser cutting high degree of flexibility, cutting speed, high efficiency, short production cycle, as the customer to win the broad market.Laser cutting without cutting force, surface machining deformation;No tool wear, good adaptability to materials;Whether simple or complex parts, can use laser rapid forming a precision cutting;Its narrow kerf width, cutting quality and high degree of automation, simple operation, low labor intensity, no pollution;Can realize automatic cutting layout, nesting, raising the utilization rate of materials, low production cost, good economic benefit.The technology of effective life time is long, the ultra structure of 2 mm plate in a foreign country mostly adopts the laser cutting, many foreign experts agree that the next 30 to 40 years is the golden period of development laser processing technology is the developing direction of the sheet metal processing).(under the impact of the original title: laser cutting, sheet metal processing and traditional advantage?)(source: jung)
