With the application of the laser cutting machine, Kunshan sheet metal processing technology has been rapidly growing, and brought a revolutionary concept to Kunshan sheet metal processing. As a traditional sheet metal cutting equipment deployment, it is important to use CNC equipment to deploy equipment, including shearing, punching, flame cutting, plasma cutting, high-pressure water cutting and so on. So what are the advantages of laser cutting machine?
Since the CNC shearing machine is important for straight-line cutting, it can cut a sheet of up to 4 meters in one knife, but it can only be used in sheet metal processing where only straight line cutting is necessary. The same is usually used in industries where sheet metal cutting, cutting, and the like are only necessary for straight cutting.
CNC punching machine has more maneuverability in curve processing. One punching machine can have one or more sets of square, round or other special requirements punches. It can process some special sheet metal workpieces at one time, the most common one. It is the chassis cabinet industry. The processing technology they require is the cutting of straight lines, square holes, round holes, etc. The pattern is relatively simple and firm. The advantage is that the processing speed of simple graphics and thin plates is fast. The disadvantage is that the ability to punch thick steel plates is limited. Even if it can be punched, the appearance of the workpiece is collapsed, the mold is required, the mold development cycle is long, the utility is high, and the flexibility level is not high.
As the original traditional cutting method, flame cutting has low requirements in terms of processing quality. When the requirements are too high, a machining process can be applied, and the market is very large. Today it is important to cut thick steel plates over 40mm. Its disadvantage is that the kerf is too wide when cutting, the thermal deformation is too large, the material is wasted, and the processing rate is too slow, and it has to be roughed.
Plasma cutting and fine plasma cutting are similar to flame cutting. The heat affected zone is too large, and the precision is much larger than the flame cutting. The rate also has a number of Pentium, which has become the main force in the processing of the plate. The disadvantage is that when the steel sheet is cut, the thermal deformation is too large, the slope is also large, and when the precision is high, there is no power, and the product is relatively expensive.
High-pressure water cutting is the cutting of sheet metal using the doped diamond experiment in high-speed water jet. It is not limited to the material, and the thickness of the cutting is almost 100mm or more. It is also easy to burst when hot cutting is used for ceramics and glass. Can be cut, copper, aluminum and other laser high-reflection material waterjet can be cut, but 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 product is also high.
Laser cutting is a technological revolution in sheet metal processing, and it is the "processing center" in sheet metal processing. Laser cutting has a high level of flexibility, fast cutting rate, high production obedience, and short product production cycle, which has won customers a market. Laser cutting has no cutting force, no distortion in processing; no tool wear, good material compliance; whether it is simple or large parts, it can be cut and finely formed by laser at a time; its slit is narrow, cutting quality is good, and the level of automation is high. The operation is light, the labor intensity is low, and there is no pollution; the cutting active sampling and nesting can be realized, the utilization rate of the material is improved, the production cost is low, and the economic benefit is good. The useful life of this skill is long. Most of the foreign superstructure 2mm plates are now laser-cut, and many foreign experts agree that the next 30-40 years is the golden age of laser processing skills.
