What You Should Know About Fiber Laser Cutting Machine?

fiber type

Introduction

Fiber laser cutting machine is a laser cutting machine using fiber laser generator as the light source.
Fiber laser is a new type of fiber laser which is newly developed in the world. The output laser beam with high energy density is concentrated on the surface of the workpiece, so that the area irradiated by ultrafine focal spot on the workpiece is melted and vaporized instantaneously, and automatic cutting is realized by moving the irradiation position of the spot through numerical control mechanical system.Compared with large gas laser and solid laser, it has obvious advantages, and has gradually developed into an important candidate in high precision laser processing, laser radar system, space technology, laser medicine and other fields.
Fiber laser cutting machine it can do plane cutting, can also do bevel cutting processing, and the edge is neat, smooth, suitable for high precision metal plate cutting processing, coupled with the mechanical arm can be three-dimensional cutting instead of the original imported five axis laser.Compared with ordinary carbon dioxide laser cutting machine, it saves more space and gas consumption, and has a high photoelectric conversion rate. It is a new product of energy saving and environmental protection, and also one of the world’s leading technology products.

Application materials:

You can choose the different power(1000w-20000w) to cut the different thickness materials, It’s can used for stainless steel, carbon steel, alloy steel, silicon steel, spring steel, aluminum, aluminum alloy, galvanized sheet, aluminized zinc sheet, pickling plate, copper, silver, gold, titanium and other metal sheet and pipe cutting.

Characteristics:

(1) fiber laser electro-optical conversion efficiency is high, the conversion efficiency of more than 30%, low power fiber laser without water chiller, the use of air cooling, can greatly save the power consumption at work, save operating costs, reach the highest production efficiency;
(2) The laser only needs electric energy when running, and does not need the extra gas to generate the laser, which has the lowest operation and maintenance costs;
(3) The fiber laser adopts semiconductor modularization and redundancy design. There is no optical lens in the resonator and no startup time. It has the advantages of free adjustment, free maintenance and high stability, and reduces the cost of accessories and maintenance time, which is incomparable to the traditional laser.
(4) The output wavelength of the fiber laser is 1.064 micron, which is 1/10 of the wavelength of CO2. The output beam quality is good, and the power density is high, which is very conducive to the absorption of metal materials. It has excellent cutting and welding ability, so as to minimize the cost of processing.
(5) The optical routing fiber transmission of the whole machine, does not need complex mirror and other optical guide system, the optical path is simple, the structure is stable, the external optical path maintenance free;
(6) The cutting head contains protective lens, so that the consumption of precious and consumable products such as focusing lens is very little;
(7) Light is exported through optical fiber, which makes the design of mechanical system very simple and easy to integrate with robots or multi-dimensional workbench;
(8) the laser with the optical brake can be a multi-machine, through optical fiber splitting, divided into multiple channels and multiple working at the same time, easy to expand the function, easy to upgrade, simple;
(9) fiber laser is small in size, light in weight, movable in working position and small in occupation area;

Processing advantages：

High precision, fast speed, narrow cutting slot, minimum heat affected zone, smooth cutting surface without burr. High cutting accuracy: laser cutting machine positioning accuracy 0.05mm, repeat positioning accuracy 0.03mm.
Fiber Laser cutting machine speed: cutting speed up to 30m/min maximum positioning speed up to 40m/min faster than the speed of linear cutting.
the laser cutting head will not be in contact with the surface of the material and will not scratch the workpiece.

The maintenance

How to use and maintain fiber laser cutting machine?When using fiber laser cutting machine to process objects, it is necessary to learn the use and maintenance skills of fiber laser cutting machine equipment, in order to better play the effect of the equipment and maximize the efficiency of the equipment.
Fiber laser cutting machine how to use and maintenance methods:
1) Check the steel belt regularly and make sure it is tight.Otherwise in the operation of the problem, it is possible to hurt people, serious can also lead to death.The steel belt seems to be a small thing, but the problem is a bit serious.
2) Check the straightness of the track and the perpendicularity of the machine every six months, and timely maintain and debug if abnormal.Without doing this, it is possible to cut out the effect is not very good, the error will increase, affecting the cutting quality.This is the most important and must be done.
3) Once a week, vacuum the dust and dirt in the machine, and all electrical cabinets should be closed to prevent dust.
4) The guide rail should be cleaned regularly to eliminate dust and other sundries. The rack should be wiped regularly to ensure the normal equipment, and lubricating oil should be added to ensure lubrication and no sundries.The guide rail should be cleaned and lubricated regularly, and the motor should also be cleaned and lubricated regularly. The machine can move better in the process, cut more accurately, and the quality of the product cut will be improved.
5) Dual focal length laser cutting head is a vulnerable item on the laser cutting machine, long-term use, resulting in damage to the laser cutting head.
Fiber laser cutting machine needs regular inspection and maintenance.If there is deformation or other forms, at this time you should know that the laser cutting head has been a little damaged, to be replaced.Do not replace will affect the cutting quality, increase costs, some products may also be secondary processing, reduce production efficiency.Laser cutting head to find Chinese Farilai production, when the stock should be carefully checked, so as not to use the time of the problem.
