How to Select Your Fiber Laser Cutter Machine

First of all, consider the level of the laser cutting machine. One really has to put thought in product scope, processing material and cutting thickness, for these factors collectively must be defined so as to fix machine type, cutting format and quantity purchased.  So, let’s look at it one by one.

Laser cutting machine involves electronics, sheet metal processing, printing, packaging, leather, clothing, industrial fabric, advertising, technology, furniture, decoration, medical equipment and many other industries. The mainstream format is 3015 and 2513, that is, 3 meters by 1.5 meters and 2.5 meters by 1.3 meters. In fact, now there are a variety of formats for customers to choose from, let alone customization. On-site office tour usually brings up creative solutions.

Fine cutting seam: the cutting seam of laser cutting is generally 0.10mm-0.20mm.

Smooth cutting surface: Please DO check the burr on the surface. Fengwei Fiber Laser cutting machine  somehow leads to burred surface depending on the cutting thickness and the gas used. Generally, there is no burr for thickness under 3mm. Nitrogen is normally the best choice, oxygen the second best, air the worst. Fibre optic laser cutting machine normally incurs little or no burr, effectively the cutting processing is very efficient with a smooth surface.

Power: there is no need to buy high-power laser cutting machine for plate thickness below 6mm, instead 500W optical fibre laser cutting machine would suffice. Even if the output is large, there is no need to worry that the 500W laser cutting machine would underperform the high-power one. Alternatively, a spare small-power laser cutter machine would be just as good.

Core parts: laser and laser head. Western laser are preferred, for example IPG and many other more; however these years increasingly more domestic laser have been put into use. At the same time, special attention goes to accessories of laser cutting machine, we are talking about servo motor, guide rail, and the bed; above all, targeting cutting accuracy. As for cooling cabinet, there are companies putting into use household air conditioner, which in fact is a poor cooling practice. The best way would be to deploy industrial grade air conditioning device.

Since all equipment function with a certain degree of machine wear, timely maintenance is a must. To this end, customers have to put thought in after-sale service.  

Laser cutting has certain advantages over traditional processing technique: 

1. High precision

Compared with the traditional cutting technology, its high precision is self-evident. Under normal circumstances, take Fengwei Series-C model as an example, the positioning accuracy of laser cutting is ±0.08mm, repositioning accuracy 0.02mm. Obviously it is suitable for the cutting of precision parts as well as for fine cutting of all kinds of crafts and pictures.

2. Narrow slit

The laser beam is focused into a very small point of light, which allows the focal point a very high power density. The material soon evaporates to form holes by being heated to the degree of gasification. With the relative linear movement of the beam and the material, the holes continuously form a slit with very narrow width. Generally, the incision width is 0.10 ~ 0.20mm, a very narrow slit compared with that caused by traditional mechanical cutting method.

3. Smooth cutting surface

In general, due to high cutting requirements, traditional cutting technology just doesn’t suffice, while laser cutting technology can deliver cutting surface with no blur.

4. Efficiency

Another significant advantage of the new laser cutting technology is that the cutting speed is very fast. Under normal circumstances, the maximum acceleration of the large super energy MS-0606LP model can reach 1.5g, and the maximum positioning speed tops at 60m/min, which is much faster than the speed of the gon-board machine and the punch press. For some demanding fields, laser cutting is frequently used.

5. no damage

Laser cutting involves basically no thermal deformation of the work-piece, completely avoiding the edge collapse caused by material punching and shearing. In plain words, there is no secondary processing with cutting seam. Moreover, there is no work-piece scratch problem as the laser cutting head does not come into contact with the material surface.

6. Not affected by the nature of the material

Laser can be used to process the substrate of steel plate, stainless steel, aluminium alloy plate, hard alloy and PCB industry of various materials, regardless of the material hardness. In this regard it is called deformation-free cutting.

7. No mold investment

Compared with punch processing, laser processing involves no mold usage. Therefore there is no mold consumption, less likely mold repair and replacement, thus substantially reducing the processing costs. Needless to say, it is especially suitable for the processing of large products.

8. Material Saving

With the help of computer programming, products of different shapes can be simultaneously manufactured to maximize material utilization.
