The comparison of CNC plasma cutting machine and laser cutting machine

In metal cutting, laser cutting and plasma cutting technology, in the automotive, motorcycle, ship, pressure vessel, chemical machinery, nuclear industry, general machinery, engineering machinery, textile, steel structure, such as oil is widely applied in all walks of life. So, the user when the choose and buy cutting equipment, whether choose laser cutting, plasma cutting or choose?

Wide range of plasma cutting, cutting all sheet metal and non-metallic materials, many is given priority to with plate cutting, cutting thickness of 50 mm. In the underwater cutting can eliminate the noise emitted by cutting, dust and harmful gas and arc, be conducive to the protection of the environment, accord with the requirement of environmental protection in the 21st century. Plasma cutting cooperate with different gases can cut various oxygen cutting cutting hard metal, especially for non-ferrous metal (stainless steel, aluminum, copper, titanium, nickel) cutting effect is better.

The main advantage of the plasma cutting is cutting thickness of metal artifacts, plasma cutting speed, especially in the ordinary carbon steel thin plate cutting, cutting speed of oxygen method of 5 ~ 6 times, cut surface is bright and clean, the thermal deformation of small, almost no heat affected zone. Plasma cutting can be used in the working gas (work on the plasma arc gas conductive medium, it is with the hot body, but also eliminate incision in the molten metal) of plasma arc cutting properties and cutting quality, speed, have apparent effect. Commonly used plasma arc work with argon gas, hydrogen, nitrogen, oxygen, air and water vapour and some mixed gas.

Objects of application of laser cutting in the case of high power CO2 laser cutting, laser cutting range mainly include four categories:

First class from technical and economic point of view, the laser cutting instead of die stamping metal sheet metal parts, especially the contour shape is complex, volume is not large, generally less than 20 mm thickness of mild steel, 10 mm thick of stainless steel. Typical products are: all kinds of electrical cabinets, switch cabinets, elevator components, elevator panels, machine tools and outer garment grain machinery, textile machinery parts, engineering machinery structure, large motor silicon steel sheet, etc.

The second category, almost impossible to use die stamping workpiece, mainly used in decoration, advertising, service industries, such as stainless steel (average thickness of 3 mm) or non-metallic materials (20 mm) thickness of general design, tag, font, etc.

The third class, cutting requires uniform kerf width of special parts, packaging and printing industry is the most widely used typical parts with the die cutting plate. In addition, the laser can cut plastic (polymer), rubber, wood, paper products, leather and organic material such as natural and synthetic fabric; At the same time also can cut inorganic material such as quartz, ceramic, can cut new lightweight reinforced polymer composite materials, etc.

The fourth class, cutting three-dimensional workpiece, the use of 3 d laser cutting system or configuration, industrial robot, cutting the space curve, such as automotive covering parts, the doors, trunk, etc.

From the point of development trend, kunshan nc cutting machine CNC flame cutting machine on the market will maintain its basic market, water jet cutting market will have a certain degree, the CNC plasma cutting machine, CNC laser cutting machine will be the mainstream in the plate cutting market forces, special profiles CNC cutting equipment, contact and non-contact nonmetal special nc cutting equipment will also have the larger development space, the kunshan nc cutting machine market will continue to expand. Improve the production efficiency of kunshan nc cutter and cutting quality, reduce production cost, enhance the automation level and the stability of the system, perfect the system function has become the developing direction of the technology.
