Problems often encountered by optical fiber laser cutting machine

Last time, we learned about the burr problems often encountered by optical fiber laser cutting machine when cutting carbon steel plates. Next, let’s take a look at other problems encountered in the process of laser cutting.

1、 Abnormal sparks often occur when cutting thin carbon steel

We know that when laser cutting thin sheet carbon steel, normally speaking, the spark beam is long, flat and has few forks, while abnormal sparks will affect the smoothness and processing quality of the cutting surface of the workpiece. If other parameters are normal, the following conditions shall be considered:

1. The nozzle of laser cutting head is seriously damaged, and the old nozzle should be replaced in time;

2. Increase the cutting auxiliary gas pressure without replacing the new nozzle;

3. If the thread at the connection between the nozzle and the laser cutting head is loose, stop the laser cutting immediately, check the connection status of the laser cutting head, and fix the thread again.

2、 . Laser not completely cut

1 The selection of the laser nozzle does not match the thickness of the processed plate, replace the nozzle or process the plate;

2. The linear speed of laser cutting is too fast, so the linear speed needs to be reduced by operation control.

The cutting quality of optical fiber laser cutting machine is poor. Here are some tips

For new laser cutting operators, they will be in trouble when encountering laser cutting quality problems. They don’t know how to adjust many parameters on the desktop of the console. Let’s simply sort out the problems encountered and solutions.

Those who have been engaged in laser technology know that the hardware conditions that affect the quality of laser cutting include: protective lenses, gas purity, plate quality, focusing and collimating mirrors; Parameters include: focus position, cutting height, cutting nozzle model, cutting frequency, cutting power, cutting air pressure, cutting speed and cutting duty cycle.

In case of poor laser cutting quality, it is recommended to conduct an inspection first. The main inspection contents include:

1. The actual cutting height is recommended to be 0.8~1.2mm. If the actual cutting height is inaccurate, calibration is required;

2. It is recommended to use a cutting nozzle with a diameter of 1.0 to check the optical center. When checking the optical center, the focus should preferably be between – 1 and 1, so that the light spot produced is small and easy to observe;

3. Check whether the model and size of the cutting nozzle are used incorrectly. If it is correct, check whether the cutting nozzle is damaged and whether the roundness is normal;

4. Check whether the focus is set correctly;

5. Protect the lens. Check whether the lens is clean. It is required to be free of water, oil and slag. Sometimes, the lens may be fogged due to weather or too cold air;

6. Modify cutting parameters.

After all the above six items are checked and there are no problems, modify the parameters according to the cutting problems.

How to achieve fine cutting with optical fiber laser cutting machine

Optical fiber laser cutting machine is more and more widely used in aerospace, medical equipment, precision instruments and other industries for parts processing because of its high-precision laser cutting processing. How can optical fiber laser cutting machine achieve fine cutting?

As we all know, laser is known as the brightest light, the most accurate ruler and the fastest light. Through technical means, the laser can gather quite high energy on a very small unit area, so that metal and other materials can melt or vaporize rapidly, thus playing the role of cutting.

The focused beam can usually reach about 0.1mm, which is like a very delicate knife, of course, much more sophisticated than the “big axe”. At the same time, due to the large energy density of processing, the time acting on the material is very short, so that the workpiece has small heat affected zone, small thermal deformation, and small thermal stress. In addition, the laser is non mechanical contact processing, which has no mechanical stress on the workpiece, and is suitable for precision processing.

Secondly, a stable machine tool system is the basis for maintaining the accuracy of the optical fiber laser cutting machine. Through rigorous mechanical design, precision welding, stress relief and other operations, the optical fiber laser cutting machine is smooth and stable in operation, and can maintain long-term accuracy.

Finally, the fiber laser cutting machine can achieve precision cutting thanks to its high-precision transmission structure, including gear rack, servo motor, reducer, etc.

To sum up, the optical fiber laser cutting machine can achieve fine cutting.

Use and maintenance skills of optical fiber laser cutting machine

The optical fiber laser cutting machine needs regular inspection and maintenance:

1. Check the steel belt frequently to ensure that it is tight. Otherwise, if there is a problem during operation, people may be injured and even killed. The steel belt looks like a small thing. If something goes wrong, it is still a bit serious.

2. Check the straightness of the track and the perpendicularity of the machine every six months, and timely maintain and debug in case of any abnormality. If this is not done, the cutting effect may not be good, and the error will increase, affecting the cutting quality. This is a top priority and must be done.

3. Use a vacuum cleaner once a week to remove the dust and dirt in the machine, and all electrical cabinets should be tightly closed to prevent dust.

4. All guide rails shall be cleaned frequently to remove dust and other sundries, to ensure that the normal rack of the equipment shall be wiped frequently, and lubricating oil shall be added to ensure lubrication without sundries. The guide rail shall be cleaned and lubricated frequently, and the motor shall also be cleaned and lubricated frequently, so that the machine can move better and cut more accurately, and the quality of the cut products will be improved.

5. The double focus laser cutting head is a vulnerable item on the laser cutting machine, which is damaged due to long-term use.

If there is deformation or other forms, you should know that the laser cutting head has been damaged and should be replaced. Not replacing will affect the cutting quality and increase the cost. Some products may need to be processed again to reduce production efficiency.

Cleaning and maintenance of focusing lens of cutting machine

For the laser cutting machine, it has been used for a long time, and some accessories need to be replaced frequently to ensure the stable performance of the laser cutting machine. These accessories are called wearing parts. Nozzles and lenses are the most frequently replaced accessories of the laser cutting machine.

The focusing lens is a relatively precise optical element, and its cleanliness directly affects the processing performance and quality of the laser cutting machine. Therefore, it is necessary to maintain the focusing lens regularly. Today, we have brought you the maintenance process and key points for focusing lenses. Let’s look down~

The correct operation procedure for maintaining the focusing lens of the laser cutting machine:

1. Take out the focusing lens from the lens frame: loosen the fastening screws and take down the air nozzle and the lens barrel in turn; First, use the blowing balloon to blow away the dust on the lens surface;

2. If it is really necessary to clean the lens, only laboratory grade paper soft cotton balls can be used, dipped with appropriate amount of acetone or high retention alcohol, and gently rotated clockwise from the center of the lens to the edge. Both sides of the lens need to be cleaned when necessary, and they should be carefully scrubbed;

3. Install the lens barrel and air nozzle, adjust the focus, tighten the fastening screws, and ensure that the convex face is downward when installing the focusing lens.

Pay attention to the following three points when maintaining the focusing lens of the laser cutting machine:

1. The focusing lens is made of ZnSe (zinc arsenide), which is brittle and is afraid of falling; Attention shall be paid during disassembly: do not use too much force or collide with hard objects. There is an antireflection film on the surface, which is afraid of pollution, moisture, oil and scratch; Therefore, it is required to provide dry and degreased air during work. Never handle the lens of the laser cutting machine focusing lens directly by hand, because skin grease will cause permanent damage to the lens surface. On the contrary, you can wear gloves and special sets for operation. For smaller lenses, it will be more convenient to use optical tweezers or vacuum tweezers. No matter what method is used to clamp the focusing mirror of the laser cutting machine, it can only be clamped along the non optical surface, such as the frosted edge of the mirror plaque.

2. In general, the focusing lens of the laser cutting machine should be checked before use and before and after cleaning. Because the size of most contaminants and surface defects is relatively small, we often need to use magnification equipment when checking lenses. In addition to amplification equipment, sometimes we also need to use a relatively bright light to illuminate the optical surface to enhance the specular reflection intensity of surface contaminants and defects, so that pollutants and defects can be found more easily.

3. When cleaning the focusing lens of a laser cutting machine, always use clean wiping paper and optical grade solvent to prevent damage by other pollutants. Wiping paper must be moistened with appropriate solvent, and must not be used dry. In consideration of softness, the available wiping paper is pure cotton Webril wiping paper or cotton ball, lens paper, cotton swab and other applicators.

Although it is troublesome to clean and maintain the focusing lens of the laser cutting machine, good cleaning and maintenance operations can extend the service life of the lens, improve the efficiency and save costs for enterprises, which can be said to be twice the result with half the effort. When the high cleanliness is still not reached after cleaning for many times, it needs to be replaced to ensure the processing efficiency of the laser cutting machine, so as not to delay production.

How to adjust the light path of laser cutting machine

1. For the adjustment of the first light, stick the masking paper on the dimming target hole of reflector A, manually jog the light (note that the power should not be too high at this time), fine tune the base of reflector A and the laser tube bracket, so that the light hits the center of the target hole, and pay attention that the light cannot be blocked.

2. The adjustment of the second light, move the reflector B to the remote, use a piece of cardboard to guide the light into the cross light target from near to far, because if the remote light is in the target, the near end must be in the target, and then adjust the near end and remote light spot to be the same, that is, how the near end is deflected, and how the remote is deflected, so that the cross is in the same position in the near end and remote light spot, that is, whether the near end (far end) indicates that the light path is parallel to the Y-axis guide rail.

3. The adjustment of the third light (note: the cross splits the light spot to the left and right), move the reflector C to the remote, guide the light into the light target, shoot the target at the inlet and the remote respectively once, and adjust the position of the contrast cross to be the same as the position of the cross in the near-end light spot, which indicates that the beam is parallel to the X-axis. At this time, if the optical path is inward or outward, it is necessary to loosen or tighten M1, M2 and M3 on the mirror frame B until they are split left and right.

4. For the adjustment of the fourth light, stick a piece of masking paper to the light outlet, make the light outlet hole leave a circular mark on the adhesive tape, click the light outlet, take down the adhesive tape to observe the position of the small hole, and adjust M1, M2, M3 on the mirror frame C as appropriate until the light spot is round and straight.

Measuring method of focal length: use the focal length ruler provided by our laser cutting machine manufacturer to lift the nozzle up and down on the number 5 of the focal length ruler. At this time, the light is the brightest and strongest, and then tighten the screws.

How to select fiber laser cutting machine manufacturers? How much is the price?

–Understanding the product:

Fiber laser cutting machine is a laser cutting machine using fiber laser generator as light source.

Fiber laser is a new type of fiber laser developed internationally that outputs high energy density laser beam and gathers on the surface of the workpiece to melt and vaporize the area on the workpiece illuminated by the ultra-fine focus spot instantly. Automatic cutting is realized by moving the spot irradiation position through the numerical control mechanical system. Optical fiber laser cutting is widely used in automobile, sheet metal processing, precision accessories decoration, advertising, metal external processing and other manufacturing and processing industries.

–Understanding power:

Optical fiber laser cutting machine can choose power: 500W  800W  1000W  1200W  1500W  2000W/3000W, etc. Different power, different price, cutting speed and cutting thickness are different.

800-1000W power is most suitable for the factory’s own metal laser cutting machine. It is better to choose high power when the economy of sheet metal processing power allows, which has advantages for external processing. It is also possible to consider the cost-effective dual purpose laser cutting machine for super high management boards, as well as the functions of cutting round tubes and square tubes, which are not available for external processing. The Chinese way of doing this is multi-functional and practical, and it has great competitiveness in the external market.

At present, there are countless manufacturers of optical fiber laser cutting machines in China, with technology precipitation and product quality, so how do we choose a reliable manufacturer of optical fiber laser cutting machines when we choose optical fiber laser cutting machines? The following aspects can be considered:

Four factors for selecting optical fiber laser cutting machine

When purchasing optical fiber laser cutting machine, in addition to considering whether it can meet some basic elements such as cutting thickness and cutting plate, we should also consider many factors such as the price of optical fiber laser cutting machine.

1. Understand whether the optical fiber laser cutting machine meets the cutting requirements, such as the maximum size and material of the processed plate, the thickness of the plate that can be cut, and the breadth that can be completed. In a word, the equipment should be selected according to the needs of the enterprise’s own processing technology. The best choice is the optical fiber laser cutting machine that can properly meet the enterprise’s own processing level.

2. The performance of optical fiber laser cutting machine, the machine with fast cutting speed, high precision, high processing efficiency and good cutting effect is naturally the first choice for us to purchase equipment.

3. Stability of optical fiber laser cutting machine performance. How to complete customer orders with quality and quantity guaranteed and how to purchase laser processing equipment with stable performance is the basis.

4. After sales service. It is inevitable to encounter some problems in the process of using the optical fiber laser cutting machine, so high-quality after-sales service is particularly important. Instead of choosing products with low price but no perfect after-sales service, we should choose machinery and equipment with excellent performance, high stability and high-quality after-sales service.

Just to say one thing, the laser cutting machines of domestic brands are the same. No matter big brands or newly established manufacturers, the difference is not as big as the price difference. Just like many domestic manufacturing industries, the main parts are imported, and they only provide assembly. What do you think is the difference? Only workshop workers are different.

So how do customers choose? In fact, the configuration is relatively important. At present, the configurations on the market have been tested and demonstrated, so the general configurations can be used. When choosing a machine, you only need to choose a very small manufacturer of optical fiber laser cutting machine. In this way, there is no after-sales service after buying the machine. The reason is that the company has no strength to go to after-sales service, and the company has not calculated the after-sales cost for you. Do you dare to buy it?

Don’t choose the most expensive or the cheapest. Choose from the middle price. The high price brand is too high, and the low price brand is too low to use. The medium price brand is the main battle field in the market, and there is little profit margin.

 

Basic knowledge of laser cutting machine

In metal processing, optical fiber laser cutting machine, with its advantages of high efficiency and high quality, has gradually replaced the traditional process and become a professional weapon in metal processing.
But even if the same is called optical fiber laser cutting machine, the processing power and effect of different equipment inside will be very different. For optical fiber laser cutting machine, the six core accessories must be considered when purchasing.
1. Fiber laser
Laser is the core “power source” of laser equipment, just like the car engine, it is also the most expensive part of the fiber laser cutting machine. Now the imported brands of fiber lasers on the market include IPG, ROFIN, SPI in the UK, and Coherent in the US
With the development, domestic laser brands such as Ruike and Chuangxin are also emerging and gradually recognized by the market with high cost performance.
For a long time, China’s lasers have basically relied on imports, which are expensive and have a long supply cycle, leading to the high price of high-power fiber laser cutters. The appearance of a hundred schools of thought contending among Chinese fiber laser manufacturers has broken the monopoly of foreign enterprises in the laser field, and also directly
Lower the price of imported products.
2. Cutting head
The cutting head is the laser output device of the optical fiber laser cutting machine, which is composed of a nozzle, a focusing lens and a focusing tracking system. The cutting head of the laser cutting machine will walk according to the set cutting path, but the height of the laser cutting head is high under different materials, different thicknesses and different cutting methods
Degrees need conditioning and manipulation.
3. CNC system
The control system is the leading operation system of the fiber laser cutting machine. The first thing is to control the machine tool to achieve X, Y, Z axis movement, and also control the output power of the laser. Its quality determines the stability of the operation function of the optical fiber laser cutting machine. Through the accurate control of the software
To improve accuracy and cutting effect. Now commonly used Beckhoff CNC system, PA CNC system, Farianka system, etc.
4. Motor
The motor of the laser cutting machine is the core component of the motion system. The function of the motor directly affects the product processing effect and output power. Now the commonly used motors include stepping motors and servo motors. According to the occupational type and product type of the processing object, the most suitable motor is equipped
Stepping motor: fast starting speed, flexible response, suitable for carving and cutting with low requirements. The price is low. There are many brands of stepping motors with different functions.
Servo motor: fast movement, stable movement, high load and stable function; The edge of processed products is smooth and the cutting speed is fast; The high price is suitable for occupations and products with high processing requirements.
5. Machine tool
Fiber laser cutting machine requires very high stability of the machine tool. High precision and high stability of the machine tool is conducive to improving the accuracy of laser cutting. At present, the mainstream machine tools in the market are gantry type, cantilever type, beam type, etc. Different machine tools have different effects. For example, beam type machine tools are mainly used
For material cutting of large manufacturers, there are also models for specific categories, such as 3D optical fiber laser cutting, mainly for car occupation.
6. Laser lens
Laser lenses are the most widely used in the whole fiber laser cutting equipment. Many optical devices contain laser lenses. Different lenses have different effects, including full reflective lenses, semi reflective lenses, and focusing lenses.
The quality of the lens directly affects the output power of the laser, as well as the function of the whole machine. The same lenses are also divided into domestic lenses and imported lenses. The service life and cutting effect of domestic lenses are not as good as those of imported lenses, but their prices are far cheaper than those of imported lenses.
