What Are the Special Skills of Fiber Laser Cutting Machine?

What are the special processes of DIY metal laser cutters? With the advancement of technology, more and more companies have begun to choose steel laser cutting machines to replace traditional cutting machines. Because compared with traditional cutting equipment, laser cutting machines steel has greatly improved both in accuracy, efficiency, and equipment functions. Therefore, it is necessary to have a certain understanding of its unique process before using the laser cutting machine metal sheet to improve our production efficiency and product process quality. Let’s take a look at the traditional cutting of the fiber metal cutting machine. Crafts that machines can't do!

 

 

 

1. Leapfrogging

According to the official definition, the leapfrog is the idle way of the laser iron cutting machine sheet. Idle travel: the CNC laser cutting machine 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 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 3000 watt fiber laser cutter 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 laser cutting machine for metal 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.

 

Instructions For Starting The Fiber Laser Cutting Machine

Because the fiber optic laser cutter uses electronic and optical components, the temperature difference between the inside and the outside will cause condensation on the surface of the optical lens and the original, which will reduce the performance of the laser and cutting head or even damage the laser and cutting head. The internal condensation of the fiber laser and the customer's use of the fiber laser The poor operating habits of the operators have a lot to do. In order to reduce the failure rate of the fiber laser and reduce the loss caused by the customer's DIY metal laser cutter shutdown, please pay attention to the following matters when operating the CNC metal laser cutter:

Switching sequence of the laser cutting steel plate machine (Strictly following the switching sequence can reduce the risk of condensation inside the fiber laser, thereby reducing the failure of the laser!

1. The startup sequence of sheet metal laser cutting machine

(1) Turn on the main power switch of the laser and let the case air conditioner or desuperheater run for more than 30 minutes.

(2) After turning on the laser for 30 minutes, turn on the power switch of the chiller.

2. The order of fiber laser shutdown

(1) Turn off the power switch of the chiller

(2) Turn off the laser power switch

If the pause time exceeds 1 hour during the startup process, the customer is advised to turn off the high voltage of the fiber laser, leave the power switch of the fiber laser, and turn off the chiller. When the product needs to be cut again, turn on the chiller to run, and when the actual temperature of the chiller's high and low-temperature water reaches the set temperature ± 1 ℃, turn on the fiber laser high pressure and then turn on the light cutting.

Note: It cannot happen that the power switch of the fiber laser is turned off, but the chiller is still running!

Fiber optic laser machine environmental requirements:

1. Make a separate air-conditioned room for the laser to improve the external working environment of the laser and keep the fiber optic laser cutter working in a dry and constant temperature environment.

2. It is recommended that the customer purchase a temperature and humidity meter and place it in the fiber laser air-conditioned room to monitor the temperature and humidity in the air-conditioned room.

3. Adjust the temperature of the chiller according to the ambient temperature. Set the high temperature to 28 32 ℃ and the low temperature to 23 27 ℃.

In summer, it is recommended that the high-temperature water in the water tank be set to 30 to 32 degrees, and the low-temperature water to 25 to 27 degrees to prevent condensation on the laser.

In addition, there are more thunderstorms in summer. In order to ensure the normal use of the fiber laser metal cutting machine, it is recommended to cut off all the power supplies of the best fiber laser cutting machine when thundering occurs, and then turn it back on after the thunder and lightning. The lightning damage is not covered by the warranty.

How To Deal With Burrs In Laser Cutting?

We all know that the main advantage of 3d metal cutter is its fast cutting speed and good cutting quality, which is deeply loved by users. The user will have burrs during actual use. Why does this problem occur? This problem has not occurred in the enclosed fiber laser cutting machine manufacturer. Is it due to the performance of the aluminum laser cutter or the laser cutting process? There is a problem? MYST Laser lists six main causes and solutions for burrs during laser cutting for these problems mentioned by users.

First, explain what burrs are, that is, there are debris and fine microscopic metal particles on the surface of metal cutting. The indicator is that the more burrs, the worse the quality of metal cutting. Here, Henan Bangtai Technology lists the main causes and methods of burrs based on 16 years of experience of cutting laser metal machine manufacturers.

1. The output power of the optical system of the sheet metal for the laser cutting machine is not enough. At this time, you need to check whether the laser generator (laser) is normal. If it emits light normally, observe whether the output value in the laser control panel is normal.

2 The cutting focus of the 2kw laser cutter is offset, which requires the operator to test the focus and adjust it according to the offset of the focus. There are certain requirements for the operating experience of the operators.

3. The upper and lower positions of the laser focus are not correct. Here, the focus test is also required. According to the offset adjustment, MYST Laser has already given an explanation of the laser cutting focus control technology. If you don’t know it, you can go to know.

4. The speed of laser cutting is too slow. Although the speed of laser cutting is relatively fast compared to other processes, the speed of the laser cutter that cuts metal in the processing process should not be too slow, causing burrs to appear. At this time, it is necessary to increase line speed. Ensure the quality of cutting.

5. The running time of the laser machine cut steel online is too long, resulting in burrs caused by the instability of the machine tool. In this case, you only need to restart the equipment.

6. When the fiber optic laser cutting machine is cutting, the purity of the auxiliary gas is not enough for hard burrs. Companies often give up the purchase of some high-cost auxiliary objects due to cost considerations, resulting in the failure to maximize the performance of the equipment. This problem also requires the attention of users and friends. Yes, it is the best choice to save costs on the premise of ensuring the cutting quality and ensuring the cutting quality.

The reasons and solutions for the above several burrs are hoped that users can master them proficiently to maximize fiber laser metal cutting machine performance and maximize economic benefits.

The Future Development Trend Of My Country's Laser Cutting Industry

In the early years,  laser cutting steel sheet machines have matured abroad and have strong competitive advantages. In recent years, domestic laser cutting stainless steel sheet machines have developed rapidly and have an absolute competitive advantage in the low-end market. Not only domestic ss laser cutting machine manufacturers have low prices, guarantees the production quality of the machines, and also provide customers with satisfactory pre-sales and after-sales services, which are recognized by customers at home and abroad.

Although my country's iron laser cutting machines have developed rapidly in recent years, occupying the low- and medium-power market, in the high-power market, the domestically produced fiber laser cut machine has not yet gained a firm foothold. Compared with foreign countries, domestic technology research and development has a certain degree. The gap in technology innovation is low, high-level production capacity is insufficient, low-level production capacity is surplus, and product technology content is relatively low.

In the past ten years, domestic laser cut stainless steel machines have developed vigorously, which has won a relatively favorable market environment for the entire industry and made great progress. However, under the general trend that the manufacturing industry is gradually developing in the direction of high-tech and intelligent, the position occupied by domestic fiber laser cutting machines in the low-end market will be greatly affected.

However, the growth rate of high value-added products will not be adversely affected, and production will continue to increase. In the future, the competition in the sheet metal laser cutter for sale industry will shift from the low-end market to the high-end market. Many domestic ipg laser cutting machine manufacturers are also aware of the changes brought about by this general trend, and while doing a good job in the low-end market, they have begun to develop into the high-end market.

In order to adapt to the development of the manufacturing industry, technological innovation is particularly critical, which is also the most direct and effective way for enterprises to upgrade and transform. In addition, enterprises who want to transform can also achieve the purpose of transformation and upgrading by changing the marketing model, changing the sales service of operators, and the way of innovating services to consumers.

Innovation is the internal driving force for the development of the CNC laser metal cutter industry. Any company that wants long-term development will actively engage in scientific research, take the initiative to innovate, and continuously upgrade its products. If the 3015 laser fiber cutting machine manufacturers in my country want to achieve rapid development in the fierce competition, they must stick to the power of knowledge, master the core technology, continue to develop and upgrade products, and improve the quality of products and services.
