Sheet metal has many advantages such as light weight, high strength, conductivity (which can be used for electromagnetic shielding), low cost and mass production performance. It has been widely used in the fields of electronics, communications, automobile industry and medical equipment, for example, Computer chassis, cell phones, MP3, sheet metal is an integral part.
Traditional sheet metal cutting equipment and equipment in the market occupy a considerable market share, in addition to their well-known reason, the main is cheaper. Although they have a significant disadvantage relative to modern processes like laser-cut sheet metal, they also have their own unique strengths.
CNC shearing machine
Because of its mainly CNC cutting machine is a straight line cutting, although it can cut a knife up to 4 meters in length, but it can only be used in the cutting of sheet metal only need to be processed. Generally used in cutting the plate after Kaiping just need straight line cutting industry.
Punch in the curve has more flexibility in processing, a punch can have one or more sets of square, round or other special requirements of the punch, you can work out a number of specific sheet metal workpiece, the most common is the chassis Cabinet industry, they require processing technology is mainly straight, square hole, round hole like cutting, the pattern is relatively simple fixed. Its advantages are simple graphics and thin plate processing speed, shortcomings is limited ability to red thick steel plate, even if the red surface is the workpiece is also a collapse, the cost of mold, mold development cycle is long, high cost, the degree of flexibility is not high enough. Foreign more than 2mm above the steel cutting are generally used more modern laser cutting, rather than using a punch, a thick steel plate when the surface quality is not high, two red thick steel plate requires a larger tonnage punch, a waste of resources, three When thick plate thick noise when the noise is not conducive to environmental protection.
Flame cutting as the first traditional cutting method due to its low investment, the past, less demanding on the processing quality, the requirements are too high when coupled with a machining process can be solved, the market is very large. Now it is mainly used to cut thick steel plate more than 40mm. Its disadvantage is thermal deformation is too large cutting, kerf width is too wide, waste of materials, and the processing speed is too slow, only for roughing.
Plasma cutting and plasma cutting with flame cutting similar to the HAZ is too large, the accuracy is much larger than the flame cutting, the speed is also an order of magnitude leap, became the main force in the plate processing. Domestic top CNC fine plasma cutting machine on-line cutting accuracy has reached the lower limit of laser cutting, cutting 22mm carbon steel plate reached more than 2 meters per minute, and the cutting end smooth and smooth, the best slope can be Control within 1.5 degrees, the disadvantage is that when cutting thin steel plate thermal deformation is too large, the slope is also greater, in high precision powerless, consumables are more expensive.
High-pressure water cutting
High-pressure water jet cutting is the use of high-speed water jet erosion of the implementation of the sheet metal cutting, it has almost no restrictions on the material, the thickness of the cut is almost up to 100mm or more, the ceramic, glass and other materials with a hot cut easily burst Can be cut, copper, aluminum and other materials on the laser highly reflective waterjet can be cut, but there is a greater laser cutting obstacles. The disadvantage of water cutting is processing speed is too slow, too dirty, not environmentally friendly, consumables are also higher.
Laser cutting is a process of sheet metal processing revolution, sheet metal processing in the "machining center." Laser cutting a high degree of flexibility, cutting speed, high production efficiency, short production cycle, customers have won a wide range of markets. Laser cutting no cutting force, no deformation of the processing; no tool wear, material adaptability; whether it is simple or complex parts, can be a laser with precision rapid prototyping and cutting; narrow cutting, cutting quality, high degree of automation, operation Simple, low labor intensity, no pollution; can achieve cutting automatic nesting, nesting, improve material utilization, low production costs, good economic returns. The effective life of the technology is long, the current foreign super-2 mm super-sheet laser cutting, many foreign experts agree that the next 30-40 years is the golden age of laser processing technology development (sheet metal processing is the direction of development) .
