Comparison of CO2 laser cutting machine with fiber laser cutting machine

From modern laser cutting, welding machine applications and user technical requirements of view, laser cutting, welding is undoubtedly the future direction of development of high-power, large-format, high efficiency, a molding, high intelligence.

Has been committed to high-power laser and plasma technology applications. Here mainly on the differences between CO2 and fiber laser cutting machine laser cutting machine for processing:

First, as mainstream conventional laser cutting, welding using a CO2 laser device can be stabilized within a 20mm cutting steel, stainless steel, less than 10mm, the aluminum alloy 8mm or less. Fiber laser cutting sheet 4mm or less obvious advantages, it is affected by poor quality solid-state laser wavelengths in the cutting plate. Laser cutting machine is not a panacea, CO2 laser wavelength is 10.6um, solid-state lasers such as YAG or fiber laser wavelength of 1.06um, the former is more easily absorbed by the non-metallic, can cut quality wood, acrylic, PP, PMMA other non-metallic materials, which is not easily absorbed by the non-metallic, non-metallic materials it can not be cut, but when confronted with two laser copper, silver, aluminum high-reflective materials are helpless.

Secondly, because of both the CO2 laser and the wavelength of the optical fiber an order of magnitude, the former can not be used in optical fiber transmission, optical fiber transmission which can greatly increase the degree of flexibility of processing. Early in the market before the fiber laser in order to achieve three-dimensional processing, we use light with high precision by the joint technical dynamic combination of CO2 laser mirror system to the three-dimensional curved surface of the guide, the realization of three-dimensional processing CO2 laser, this technique because the domestic the main limitation precision processing technology rests in the hands of a handful of American and European countries, expensive, high maintenance requirements, the fiber laser market share while gradually expanding its market has been gradually losing. The fiber laser because it can be transmitted through the fiber, the degree of flexibility than ever before, especially for the automotive industry, because basically all about 1mm thin surface machining, the fiber laser with the same flexible robotic systems, low cost, low point of failure , easy maintenance, fast and doing my part to firmly occupied this market.

Again, the fiber photoelectric conversion rate up to 25% of the laser, CO2 laser and a photoelectric conversion rate of only about 10% in terms of electricity consumption, the advantage of supporting the fiber laser cooling system is quite obvious if the fiber laser manufacturers some more , then the right price point, and solve the plate cutting process, CO2 laser threat would be enormous. However, the fiber laser as a new laser technology, penetration is far less than the CO2 laser, its stability and reliability, service and convenience remains to be long-term observation of the market.

It is worth mentioning that, according to international safety standards, laser hazard rating graded 4, CO2 laser hazards are minimal level, and fiber laser wave length due to the human body because it is big damage to the eyes, are the most harmful level, the safety considerations, a fiber laser processing needs closed environment.

In addition, the fiber laser with a robotic flexible manufacturing systems in the high position of the automobile industry and supporting industries for a long time, used to be monopolized by foreign builders in recent years due to the financial crisis and rising auto industry production technology, especially domestic laser manufacturers of high-end technology in support of national policies on research techniques under many foreign high-end car brands and national brands gleaned crab, ultra-high price of the share of foreign proud and mysterious veil has been lifted, torn, Levin in the last few in the white car to the car body welding users, car dashboard laser weakening automotive airbag laser welding, car bumpers, doors, columns and other robots in flexible cutting, laser welding, car bumpers, car exhaust pipe welding line systems, automatic car gearshift cover laser cutting equipment, etc., at the user site 24 hours a stable and efficient production.
