How Does the Cnc Laser Cutting Machine Work?

Laser cutting machine technology uses the energy released when the laser beam is irradiated to the surface of the metal sheet. The metal sheet is melted and the molten slag is blown away by the gas. Because the laser power is very concentrated, only a small amount of heat is transferred to other parts of the metal sheet, causing little or no deformation. The laser can be used to cut blanks with complex shapes very accurately, and the cut blanks do not need to be further processed.

The laser source generally uses a carbon dioxide laser beam with an operating power of 500 to 5000 watts. This level of power is lower than the power required by many domestic electric heaters. Due to the lens and reflector, the laser beam is concentrated in a small area. The high concentration of energy enables rapid local heating to melt the metal sheet.

A metal cutting machine can cut stainless steel up to 16mm, and adding oxygen to the laser beam can cut 8-10mm thick stainless steel. However, after oxygen cutting, a thin oxide film will be formed on the cutting surface. The maximum thickness of the cutting can be increased to 16mm, but the size error of the cutting part is large.

As a high-tech laser technology, since its inception, it has been developing laser products suitable for various industries, such as laser printers, laser beauty machines, laser marking CNC laser cutting machines, laser cutting machines, etc., for different social needs. The CNC laser cutting machine price is favorable, the quality is perfect, and it has received great praise.

Metal Cutting Machine

Laser cutting machine principle-principle

In the laser cutting machine, the main work is the laser tube, so we have to understand the laser tube.

We all know the importance of laser tubes in laser equipment clearly. The following is the most common type of laser tube.

The composition of the laser tube is made of hard glass, so it is a fragile and fragile substance. To understand the CO2 laser tube, we must first understand the structure of the laser tube, like this carbon dioxide laser uses a layered sleeve structure, the most inside is a layer of the discharge tube. However, the diameter of the carbon dioxide laser discharge tube is thicker than the laser tube itself. The thickness of the discharge tube is proportional to the diffraction reaction caused by the size of the spot. The length of the tube and the output power of the discharge tube also form a Species ratio.

During the operation of the laser cutting machine, the laser tube will generate a lot of heat, which affects the normal operation of the cutting machine. Therefore, a special water chiller is required to cool the laser tube to ensure that the laser cutting machine works normally at a constant temperature.

Laser cutting machine is a cutting technology that uses laser characteristics and lens focusing to concentrate energy to melt or vaporize the surface of the material. It can achieve the advantages of good cutting quality, fast speed, many cutting materials and high efficiency.

Application of Laser Marking Machine in Automobile Industry

Nowadays, laser marking machine technology is developing very rapidly. It is not only used in the metal industry, but also in the non-metallic materials industry, such as clothing accessories, pharmaceutical packaging, etc. Even the automotive industry can see it. Obviously, laser marking machine technology is very popular.

Some friends may wonder why professional laser marking machines can be used in the automotive industry?

The motor is an electromagnetic device that can convert or transfer electrical energy according to the law of electromagnetic induction.

The letter M is used in the circuit. Its main role is to generate driving torque. As a power source for electrical appliances or various machinery, it is widely used in various fields. Synchronous, but most of the IE3 motors produced in China are used for export. The automatic laser marking machine is suitable for marking motor parts and parts and is suitable for etching smooth surfaces after processing. The automatic laser marking machine adopts a unique mechanism design. The X / Z-axis of the optical table can automatically move left and right to improve work efficiency. Achieve flat batch marking, and also adapt to the rough surface (rough surface) etching of parts. Applicable materials: metal (including cast iron, cast aluminum), most non-metals (engineering plastics, rubber), etc.

Fiber Laser Marking Machine

Features of fiber laser marking machine:

1. The anti-counterfeiting effect is good: due to the complicated production equipment of laser labels, the special label materials, and the non-reusability, it is difficult for counterfeiters to evaluate auto parts, which effectively protects the legitimate rights and interests of regular auto parts manufacturers and users.

2. Low cost: Laser marking technology uses ablation and engraving to remove or melt materials. When a large number of laser tags are used for different motors, the cost is lower. Especially suitable for motor manufacturers with many motors. High-temperature resistance, wear resistance, corrosion resistance, waterproof, long service life.

3. No inventory: users can carry out laser marking at any time according to their needs without any inventory.

The performance stability of the laser marking machine is affected by various factors. Generally speaking, the more expensive the laser marking machine is, the more stable the performance stability is. The performance stability of the laser marking machine can be seen in these four factors:

1. Process level. The level of technology has an impact on all aspects of the laser marking machine, especially for the installation of beam expander, galvanometer, marking needle. If the installation position is not adjusted, it will lead to deviation of the marking position and affect the laser spot. mode.

2. Environment. The ambient temperature has an important influence on the operation of the laser marking machine. If the ambient temperature is too high or too low, the cooling capacity may be unstable. At this time, the marking effect will be unstable. Cooldown or keep warm.

3. The focal length is not accurate. The focal length of the laser marking machine will also lead to the unstable performance of the laser marking machine. At this time, the focal length needs to be adjusted.

4. The lens has abrasive dust. The laser beam of the laser marking machine engraves and marks the material through the lens. Once the lens wears and dusts, the laser beam is easily offset, resulting in a poor marking effect. At this time, the lens cleaning work will be carried out. After the lens cleaning has not achieved the effect, the lens must be replaced.

How to Correctly Adjust the Focal Length of the Laser Marking Machine?

Anyone who has used a laser marking machine or has been in contact with the laser marking machine knows that when using this device, it involves the correct adjustment of the focal plane. The equipment manufacturer will emphasize the importance of focal length during equipment installation training and sample adjustment. Engraving the laser on the surface with the correct focal length is a key factor for the device to perform its performance correctly.

Today, the OEM laser marking machine manufacturer summarized some conventional laser marking machine focal length debugging methods.

First of all, before understanding the correct debugging method, we are nowhere to popularize and understand the correct definition of focal length: Focal length, also known as focal length, is the degree of light-gathering or divergence in the optical system, which refers from the center of the lens to the focus of light distance.

In laser marking equipment, after the laser is shaped by the laser, it will illuminate the focusing field lens with a parallel beam. Most conventional laser marking equipment uses a convex lens. The convex lens passes optical refraction to focus the parallel light beam to a focal point To form the focal plane. The vertical distance from the focal point of the convex lens to the focal length surface is what we call the focal length. We usually use F = how much to express its focal length. Most laser devices are marked with a focus field lens. For example: F = 163; F = 254, and so on.

The focusing field lens is a very important optical accessory in laser marking equipment. The parallel light generated by the laser can only be brought together after the focusing lens collects light and organizes it to exert its powerful capabilities.

Common laser marking machine focusing methods on the market can be divided into front focusing and rear focusing. The laser generates laser light and enters it into the deflecting lens of the galvanometer, and cooperates with the control software to form a preset marking pattern path. Galvanometer lens refracts laser to focus

Lens, and focus the energy to the focal plane to complete the laser engraving. From this photo, we can see very vividly that the focused beam of the laser is like a tapered needle, so if the laser energy is sharper, only the Z-axis of the laser marking machine can be shaken up and down, the focal plane. But what we can't see from this picture is that when the focused concentric beam passes through the focus, due to the characteristics of the laser (good monochromaticity, good coherence, good directionality, high brightness), the beam will not end or disguise In this way, they will continue to be scattered after crossing.

Therefore, if the laser focal length surface is too high or too low, the correct focal length surface will be missed. Only on the correct focal plane, after the laser reaches the target, the laser spot is the smallest, the energy is the largest, and the sound and color are the brightest. After we have fully understood the theoretical knowledge about laser focal length, let us list several conventional methods for finding focal length:

First: continuous luminescence test method.

After marking the coating software as approximately 1 square centimeter or circle, after conventional filling, the laser energy is transferred to a larger set of parameters. Use the frequency, then check the continuous mark, and then place the metal laser projection on the product surface. Continue to move the cursor and shake the Z-axis until the energy laser of the metal business card with the largest focal length, the clearest sound, and the brightest color basically become the focal length, resulting in multiple tests to find the appropriate focal length.

This method is suitable for fiber laser marking machine with a wavelength of 1064nm, semiconductor laser marking machine, end pump laser marking machine, 355nm laser marking machine, uv 532nm green laser marking machine, etc. You can find a piece of white paper on the 3D CO2 Laser marking machine, and then draw a box in the marking software. Continuous light will shake the Z-axis, and the focal plane is the best when printing on paper.

3d Co2 Laser Marking Machine

The second method: measuring distance.

Fiber laser marking machine supplier can notify the current equipment focal length data, and then record it, and then record after each product switch. You can point the end of the ruler directly at the surface of the product. The scale value refers to the reference surface on the objective lens, which can swing up and down to zoom the data. This interview method is applicable to all laser marking machines, but the disadvantage is that if the position of the laser engraving product is concave or the steel ruler is not suitable, this method is not practical.

Third: Double red light method.

This method requires the device to have this hardware configuration at the factory. Install one or two oblique red rays next to the galvanometer or galvanometer, and use the principle of the right triangle to find the other right side of the plane by using a fixed right side and two overlapping hypotenuses. By simply rocking up and down until the two red indicators coincide, you can quickly find the focal length. In addition, if the adjustment is not good or the middle offset is performed, it is easy to mislead and form the wrong focal length surface.
