With the application of laser cutting machine, sheet metal processing technology has been rapid development, and to sheet metal processing has brought revolutionary ideas. As a traditional metal cutting equipment, mainly CNC equipment, including shearing machine, punching machine, flame cutting, plasma cutting, high pressure water cutting and so on, so the laser cutting machine and its advantages compared to what? Here we introduce to you one by one.
(NC) is mainly due to the shear line clipping, although a scissors 4 meters long sheet, but it can only be used in sheet metal processing requires only linear cutting on. Generally used in the cutting of the plate, such as the need for straight line cutting industry in Kaiping.
(CNC turret punch /) have more flexibility in curve machining, a punch can have one or more sets of square and circular or other special requirements of the punch, can a certain processing of sheet metal parts, the most common is the cabinet industry, they are the main processing requirements such as cutting line, square hole, the hole pattern is relatively simple, fixed. They are mainly facing the following 2mm carbon steel plate, the format is generally in 2.5m * 1.25M. Thickness of more than 1.5mm of stainless steel due to the viscosity of the material is too large compared to the cost of the mold, generally do not use punch. The utility model has the advantages of simple graphics and sheet processing speed, the disadvantage is punching steel plates of limited capacity, even if the surface of the workpiece is also washed collapse, fee mold, mold development cycle is long, high cost, flexible level is not high enough. Foreign steel plate over 2mm cutting generally use more modern laser cutting, without the use of a thick steel plate punching machine, the surface quality is not high, the waste is washed two punch, thick steel plate needs more tonnage of resources, three red thick steel plate with too much noise, bad for environmental protection.
Flame cutting as the original traditional cutting method because of its low investment in the past, the processing quality requirements are not high, the requirements are too high plus a machining process can be solved, the market is very large. Now it is mainly used to cut more than 40mm thick steel plate. It is the shortcomings of cutting heat cutting deformation is too large, too wide, waste material, and processing speed is too slow, only suitable for rough machining.
Plasma cutting and fine plasma cutting is similar to the flame cutting, the heat affected zone is too large, the accuracy is much larger than the flame cutting, the speed is also an order of magnitude leap, has become the main force in the plate processing. CNC precision plasma cutting machine of the domestic top precision of the actual cutting line has reached the limit of laser cutting, reached a speed of 2 meters per minute in the 22mm carbon steel plate cutting, and the cutting surface smooth, can be controlled within 1.5 degrees. The best, disadvantage when cutting thin plate when the thermal deformation is too large angle is large, the precision is incapable of action more expensive consumables.
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. Water cut is the disadvantage of the processing speed is too slow, too dirty, not environmentally friendly, consumables are also higher.
Laser cutting is a technological revolution in sheet metal processing, and is a "processing center" in sheet metal processing". Laser cutting flexibility, high cutting speed, high production efficiency, product production cycle is short, for customers to win a wide range of markets. 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 laser 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 technology is effective for a long life, at present in the foreign super structure 2 mm plate mostly use laser cutting, many foreign experts agreed that the next 30-40 years is the golden age of laser processing technology development
