Safety Knowledge that Workers Must Know When Operating Fiber Laser Cutting Machine

Fiber laser cutters are playing an increasingly important role in industrial manufacturing and other fields, and have become the "main force" to promote the development of the industry. More and more companies are purchasing metal laser cutters for production. A staff member must be clear and memorable to ensure his personal safety, and be responsible for himself, his work, and the company. Today, MYST Laser will share with you the safety knowledge that workers need to keep in mind when operating them.

 

 

 

1. Formulate and follow equipment operating regulations

Before using the fiber laser metal cutting machine, the operating procedures of the equipment should be formulated and strictly followed. Check the safety facilities of the system before starting up, especially the switch of the shutter. Maintain the machine in time to ensure the safety required by wrongdoing before, during, and after use.

2. Fire extinguishing equipment must be equipped on-site

The working principle of the fiber sheet metal laser cutter is to focus the laser light emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point, while the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material will finally form a slit, so as to achieve the purpose of cutting. During this cutting process, sparks and heat will be emitted. Therefore, the storage of flammable materials near the machine may cause a fire hazard. The working area of the machine should be equipped with fire extinguishers and other fire fighting measures. Operators should be familiar with fire fighting knowledge and know-how to use fire fighting appliances.

 

 

 

3. Manage the location of the laser cutting machine as a dangerous zone

The area where the fiber laser cutting service metals located should be designated as a hazardous area, and the area should be enclosed with a telescopic isolation belt, and the laser leakage outside the hazardous area should be guaranteed to be below the Class I reachable emission limit. Warning signs should be set up at the entrances and exits of the danger zone so that people will understand that this is a danger zone. The laser cutting machine has laser radiation when it is working, and no one is allowed to enter.

4. It is strictly prohibited to operate after fatigue and drinking

The use of laser processing equipment such as metal laser cutting machines is at a greater risk. If you are negligent, it is very likely to cause injury. Therefore, it is strictly prohibited to operate the best metal laser cutting machine after fatigue and drinking.

 

 

 

5. Protect your eyes

When working with a laser cutting fiber machine, the staff will habitually stare at the metal being cut. This subconscious action is actually very harmful to the eyes. You must wear goggles for protection. Function, because the cutting head will produce a lot of sparks during the process of cutting metal. The high brightness of the sparks will bring a tingling sensation to the eyes, cause certain damage to the cornea and retina, and cause vision loss and inability to see things. The situation occurs, so it is necessary to wear goggles.

6. Protect the respiratory system

A large amount of dust will be generated during the cutting of metal by the fiber laser cutting machine working principle. This dust will enter the lungs through the trachea and respiratory tract through breathing and will cause certain damage to the entire respiratory system. Therefore, dust-proof equipment should be used during the operation of the machine. Masks are very necessary and also a manifestation of being responsible for physical health.

 

 

 

7. Protect the skin

The fiber cutting laser machine will generate high heat during the working process, accompanied by the splash of sparks, which will cause certain damage to the exposed skin of the operator in the working environment. If you stay in this environment for a long time, you will not be exposed to your skin. To protect the skin, long-term exposure to laser radiation and high-temperature roasting will cause serious adverse effects on the skin tissue, reduce the skin’s self-repair ability, and then reduce its own immunity. Therefore, the staff must wear protective clothing during the operation. , Wear gloves on your hands and be responsible for your own health.

In order to have a better life and better work, the staff must ensure their personal safety and health every time the machine operates the optical fiber cutting machine. The safety precautions must not be sloppy. Mister Laser is sincere I hope every staff member is safe and healthy, works happily, and lives with heart.

How to Judge the Cutting Quality of Fiber Laser Cutting Machine?

The fiber laser metal cutting machine has brought earth-shaking changes to people's lives. The cutting quality is the most intuitive reference standard to reflect the performance of the desktop laser cutter for metal machine. When many people buy a laser cutting steel plate machine, they don't know how to judge its processing quality. The following MYST Laser will be popular for everyone.

1. Cutting speed: Cutting speed is an important basis for judging the level of laser cutting. The higher the cutting speed, the higher the unit output value, the lower the labor cost and electricity consumption per unit time.

2. Cutting surface roughness: When the custom laser cut steel machine cuts metal, the laser cutting section will form a vertical line. The depth of the line determines the roughness of the cutting surface. The shallower the line, the smoother the cut section. Roughness not only affects the appearance of the edge, but also affects the friction characteristics. In most cases, it is necessary to minimize the roughness, so the shallower the texture, the higher the cutting quality. The surface roughness of laser cutting mainly depends on the following three aspects: the inherent parameters of the cutting system, such as spot mode, focal length, etc.; the adjustable process parameters during the cutting process, such as power, cutting speed, auxiliary gas type and pressure, etc.; processing The physical parameters of the material, such as laser absorption, melting point, viscosity coefficient of molten metal oxide, surface tension of metal oxide, etc. In addition, the thickness of the workpiece also has a great influence on the surface quality of laser cutting. In contrast, the smaller the thickness of the metal workpiece, the smoother the cut surface.

3. Cut plane perpendicularity: If the thickness of the sheet metal cut by the laser that cuts through metal machine exceeds 10mm, the perpendicularity of the cutting edge is very important. When away from the focus, the laser beam becomes divergent, and the cut becomes wider toward the top or bottom depending on the position of the focus. The more vertical the edge, the higher the cut quality.

4. Whether there are burrs on the cut surface: In the process of cutting metal, the high energy generated by the laser beam irradiating the surface of the workpiece makes the surface of the workpiece evaporate quickly, and the residue on the surface of the workpiece is blown away by the auxiliary gas. If auxiliary gas is not used, burrs will be formed after cooling the residue and adhere to the cutting surface. Because deburring requires extra work, the severity and amount of burrs can intuitively judge the quality of cutting.

5. Cutting seam width: Generally speaking, the cutting width does not affect the cutting quality. The cutting width has an important influence only when a particularly precise contour is formed inside the part. This is because the cutting width determines the minimum inner warp of the contour. When the thickness of the plate increases When, the cutting width also increases.

6. Heat Affected Area: As a thermal cutting processing application equipment, a desktop metal laser cutter will inevitably have a thermal effect on metal materials during use. Its manifestations mainly include three aspects: heat affected area; depression and corrosion; material deformation. The heat-affected zone refers to the area around the incision being heated during laser cutting. At the same time, the structure of the metal changes. For example, some metals will harden. The heat-affected zone refers to the depth of the area where the internal structure changes; and the depression and corrosion have an adverse effect on the surface of the cutting edge and affect the appearance. They appear in cutting errors that should generally be avoided; in the end, if the cutting causes the part to heat up sharply, it will deform. This is particularly important in fine machining, because the contours and connecting pieces here are usually only a few tenths of a millimeter wide. Controlling the laser power and using short laser pulses can reduce parts heating and avoid deformation.

7. Operational convenience: The hobby laser cutter metal is easy to operate, easy for the staff to use, and the work efficiency will be improved.

8. Stable performance: The performance stability of metal cutting laser cnc machine is directly related to the later use effect. Therefore, when purchasing laser equipment, pay attention to long-term performance and service life.

What Materials Can and Cannot be Cut By the Fiber Laser Cutting Machine?

CNC fibre laser cutting machine is more and more widely used in various industries, mainly because of its versatility. Sheet metal laser cutting can cut various metals, foam, wood, cork, paper, acrylic, and other materials, When using a custom metal laser cutting, you should understand the characteristics of the material you are cutting. MYST Laser will show you what materials the CNC metal laser cutter can and cannot cut.

Materials that can be cut:

metal

Laser cutting steel sheet machines can cut all types of metals from carbon steel, stainless steel to non-ferrous metals. Highly reflective metals such as aluminum can also be cut. The maximum thickness of the cut metal will also vary due to the power of the laser.

 

Paper and cardboard

Most of the complicated and exquisite wedding invitations that I see every day are made by laser cutting.

wood

All types of wood (including plywood and MDF) can be cut with a laser, but some oily woods may be ignited, so you should pay special attention when cutting.

plastic products

Acrylic, PMMA, and Lucite are all transparent plastics. When using laser cutting, you can ensure that the edge has a good finish, like a buttery surface cut with a knife.

Polyoxymethylene

Polyoxymethylene is a highly used plastic in the engineering field. It can be used for gears, guide and sliding elements, medical equipment, food packaging, etc. The use of laser for cutting is helpful to the wider use of POM in many fields.

glass

Due to its fragile and reflective properties, laser cutting glass seems an impossible task. However, the DIY metal laser cutter’s fast cutting speed and stable cutting effect make it possible to complete this task.

 

 

Materials that cannot be cut:

Because the cheapest metal cutting laser machine has the characteristics of fast cutting speed and good cutting effect, most materials can be cut, but most plastics will undergo chemical reactions at high temperatures, making laser cutting impossible.

glass fiber

Glass fiber is a mixture of glass and epoxy resin. Epoxy resin is easy to cause smoke, and it is relatively difficult to cut glass alone. Therefore, glass fiber is not suitable for stainless laser cutting machine cutting.

Polyvinyl chloride

The cutting process will emit acid and toxic fumes, which will endanger the health of the staff who operate the machine and cause pollution to the environment.

Polycarbonate

When the polycarbonate fiber is cut by laser, the color of the material surface will change, and it may cause burning when the material is thick.

Polystyrene and polypropylene foam

Both are flammable when heated, so they are not suitable for laser cutting.

ABS, high-density polyethylene

Because the temperature of the laser beam is high enough to vaporize the material, materials such as ABS and high-density polyethylene are not supported. They tend to melt more than vaporization, so they are not suitable for laser cutting.

After having a certain understanding of the types of materials that can and cannot be cut by the CNC laser cutter steel, the operation and use of cutting opportunities are safer and more efficient.
