Cutting Mode And Characteristics Of CNC Fiber Laser Cutting Machine

What Is cnc fiber laser cutting machine? 

CNC fiber laser cutting machine is a kind of CNC laser metal cutting system with high quality, high speed, high precision and high efficiency. It is suitable for all kinds of metal cutting which will be your good metal working partner. It is equipped with different powers (from 1000W to 15000W) for cutting metal sheets/plates and metal tubes/pipes of stainless steel, carbon steel, electrical steel, galvanized steel, aluminum zinc plate, aluminum, aluminum alloy, titanium alloy, copper, brass, iron and other metal materials with different thicknesses. cnc fiber laser cutting machine is also known as fiber laser metal cutting machine, fiber laser cutting machine, fiber laser cutting system, cnc fiber laser cutter ,fiber laser cutting equipment.

1. Leapfrogging

According to the official definition, the leapfrog is the idle way of the cnc fiber laser cutter sheet. Idle travel: the cnc fiber laser cutter 1000w moves without cutting. For example, the machine cuts hole 1, and then cuts hole 2. The cutting head must move from point A to point B. Of course, it must be closed during the move. The movement process from point A to point B, the machine runs "empty", which is called idling. However, if a parabolic motion is used between points AB, instead of cutting at point A and then closing the cutting head to point B to cut, this can reduce the time for the cutting head to lift, greatly reduce the user's cutting cost, and improve the user's cutting efficiency. This new process is called "leapfrogging". The most notable feature of the leapfrog is higher accuracy and faster speed. The 

cnc fiber laser cutting machine with a leapfrog function is actually a technology that changes the Z-axis empty path.

2.  automatic focusing

When cutting different materials, the focus of the laser beam is required to fall on different positions of the cross-section of the workpiece, as shown in the figure below, so it is necessary to constantly adjust the focus position. Some people think that as long as the height of the cutting head is changed, the cutting head rises, the focus position rises, and the cutting head lowers, the focus position decreases. In fact, it is not that simple. As we all know, the bottom of the cutting head is the nozzle. During the cutting process, the distance between the nozzle and the workpiece (nozzle height) is about 0.5~1.5mm, which is a fixed value, that is, the nozzle height does not change, so you cannot adjust the focus by lifting the cutting head. , Otherwise, the cutting process cannot be completed. The focal length of the focusing lens cannot be changed, so the focus cannot be adjusted by changing the focal length. Changing the position of the focusing lens can change the focus position: when the focusing lens drops, the focus drops; when the focusing lens rises, the focus rises. This is also a common automatic focusing method, which drives the focusing lens to move up and down through a motor. Another automatic focusing method is to configure a variable curvature mirror before the beam enters the focusing mirror, and change the divergence angle of the reflected beam by changing the curvature of the mirror, thereby changing the focus position.

3.  automatic edge finding

If the sheet material is skewed, it may cause waste during cutting. If the cnc fiber laser cutting machine can sense the angle and origin of the sheet material inclination and adjust the cutting process to suit the angle and position of the sheet material, waste can be avoided. After the automatic edge finding function is activated, the cutting head starts from point P and automatically measures 3 points on the two vertical edges of the sheet: P1, P2, P3, and automatically calculates the inclination angle A of the sheet and The origin, with the help of the automatic edge finding function, can effectively save the time of workpiece adjustment, reduce the intensity of human work, and thus improve the cutting efficiency.

4. Common edge cutting

If the contours of adjacent parts are straight and the angles are the same, they can be combined into a straight line and cut only once, that is edge cutting. Obviously, edge cutting reduces the cutting length and can significantly improve processing efficiency. Co-edge cutting does not require the shape of the part to be rectangular. Co-edge cutting not only saves cutting time but also reduces the number of perforations, so the benefits are very obvious. If you save 1.5 hours per day due to common edge cutting, you save about 500 hours per year, and the hourly comprehensive cost is calculated at 100 yuan, which is equivalent to creating an additional 50,000 yuan benefit a year.

The above is the unique process of cnc fiber laser cutting machine compared with a traditional cutting machine. Overall, it seems that progress is still very large! This is one of the reasons why some companies cannot afford the equipment and have to purchase it in installments.

Working principle of cnc fiber laser cutting machine

The machine runs on laser light produced by fiber lasers. The laser is generated through an optical path that focuses the fiber laser beam on the substance used with a very high power density. Then, the laser beam is irradiated on the metal surface so that the metal reaches its melting point or boiling point. During this period, the high-pressure gas is connected to the fiber laser beam and blows away the molten or vaporized material.

During all these operations, the laser beam will move corresponding to the metal. Therefore, cut the material and achieve the purpose of cutting
