What Is Metal Laser Cutter?
A metal laser cutter is an automatic CNC metal cutting machine that uses a laser beam to cut specified shapes and contours out of metal sheets, plates, bars, panels, profiles, straps, tubes and pipes, which is the best metal cutting solution for hobbyists and industrial manufacturers.
A laser metal cutter a high-speed computer numerical controlled metal cutting system that works with a CAM software to instruct the laser to shape 2D/3D metal cuts made of hard metals such as stainless steel, galvanized steel, carbon steel, mild steel, cold & hot rolled steel, iron, magnesium, zinc, titanium and alloy, as well as highly reflective metals including copper, brass, silver, gold, aluminum and bronze.
A laser metal cutting machine is an eco-friendly precision cutting tool kit that comes with a CNC controller for automatic sheet metal and tube fabrication to create individual shapes and outlines, as well as perform various roughing and finishing for metal strips, rods and profiles, which consists of bed frame, power supply, generator, reflection path, cutting head, chiller, control panel and software.
How Does A Laser Metal Cutting Machine Work?
A metal laser cutting machine is a smart metal cutting system working with a CNC controller to drive the fiber or CO2 laser beam to cut in any direction, angle, bevel and slope according to the designed layout file, and create shapes and outlines you want.
The energy of the laser is concentrated into a high-density beam in the form of light. The beam is transmitted to the work surface, generating enough heat to melt the material, and the high-pressure gas coaxial with the beam directly removes the fused metal to achieve the purpose of metal cutting. This shows that laser metal cutting is essentially different from CNC machining.
It uses the laser beam emitted from the generator to focus on the beam irradiation condition of high power density through the external circuit system. The heat is absorbed by the metal part material and the part temperature rises sharply.
After reaching the boiling point, the material begins to vaporize and form holes, as the relative position of the beam and the part moves, will eventually form a slit in the material. The technological parameters (cutting speed, power supply, gas pressure) and movement trajectory during slitting are controlled by the CNC system, and the slag at the slit is blown off by the auxiliary gas with a certain pressure.
During laser-cut metal, auxiliary gas suitable for the material to be cut is also added. When cutting steel, oxygen must be used as an auxiliary gas to produce an exothermic chemical reaction with the molten metal to oxidize the material, while helping to blow away the slag in the slit. For metal parts with high processing accuracy, nitrogen can be used as an auxiliary gas in the industry.
What Are Laser Metal Cutters Used For
A laser metal cutting system is applied in industrial manufacturing, school education, small business, home use, small shop and home store for sheet metal fabrication, aviation, spaceflight, electronics, electrical appliances, kitchenware, auto parts, office supplies, furniture kitchen dining, subway parts, automobile, machinery, precision components, ships, metallurgical equipment, elevator, household appliances, metal signs, logos, tags, profiles, letters, words, arts, crafts, gifts, tool fabrication, foils, adornment, advertising and other metalworking industries.
Most organic and inorganic materials can be cut by laser. In the metal fabrication industry, which occupies a heavy weight in industrial manufacturing, many metals, regardless of their hardness, can be cut without deformation. Of course, for high-reflectivity materials such as gold, silver, copper and aluminum alloys, they are also good heat transfer conductors, so laser cutting is difficult or even impossible to cut (some difficult materials can be cut using pulsed laser beams, due to the extremely high peak power of the pulse wave, the absorption coefficient of the material to the beam will increase sharply instantly).
They can cut stainless steel, carbon steel, tool steel, galvanized steel, spring steel, alloy, iron, aluminum, copper, brass, silver, gold, titanium, nickel, manganese, cobalt, chromium, lead and other metals in hobby use, home business, small shop, commercial use, and industrial manufacturing.
Stainless Steel
For the manufacturing industry dominated by stainless steel sheets, the laser metal cutter is an effective cutting tool. When the heat input is strictly controlled, the width of the heat affected zone of the trimming edge can be limited, thereby ensuring good stainless steel The corrosion-resistant type. Laser cut of stainless steel uses the energy released when the beam is irradiated to the surface of the steel plate to melt and evaporate the stainless steel. For the manufacturing industry that uses stainless steel sheets as the main component, laser cut of stainless steel is a fast and effective cutting method. The important process parameters that affect the cutting quality of stainless steel are cutting speed, power supply, air pressure and so on.
Carbon Steel
The thickness of the laser cut of carbon steel plate can reach 70mm, the slit of carbon steel cut by oxidation flux cutting mechanism can be controlled within a satisfactory width range, and the slit of thin plate can be narrowed to about 0.1mm.
Copper & Alloys
Pure copper (purple copper) is too high reflectivity, laser cut of brass (copper alloy) should use higher power, auxiliary gas using air or oxygen, can cut thinner plates. Pure copper and brass has high reflectivity and very good thermal conductivity. Pure copper and brass can only be cut when a “reflective absorption” device is installed on the system, otherwise the reflection will destroy the optical components.
Aluminum & Alloys
The cut of aluminum plates is easy to do with fiber lasers, which have high performance whether it is cutting aluminum or aluminum alloy.
Nickel & Alloys
They are also known as high-temperature alloys with many types, most of them can be laser oxidized and flux-cutting with good cuts.
Titanium & Alloys
Pure titanium can be well coupled with the heat energy converted by the focused beam. When the auxiliary gas uses oxygen, the chemical reaction is violent and the cutting speed is fast, but it is easy to form an oxide layer at the cutting edge, which may also cause over-burning. Therefore, the use of air as an auxiliary gas can ensure the cutting quality. Laser cut of titanium alloys is commonly used in aircraft manufacturing. Titanium plates are cut with nitrogen and nitrogen as working gases.

Expert Skills
When using a laser metal cutting machine, it is necessary to pay attention to some small details and precautions. Only by mastering the use skills can the machine cutting efficiency be higher.
Corner Melting
When decelerating to cut the corners of thin sheets, the laser can overheat and melt the corners. A small radius is generated at the corner to maintain the high-speed cutting and avoid the phenomenon of overheating and melting of the steel plate when cutting the corner, so as to achieve good cutting quality, reduce cutting time and improve manufacturing force.
Part Spacing
Usually, when cutting thick plates and hot plates, the distance between parts should be large. Because the heat of the thick plates and hot plates is greatly affected, it is easy to burn edges when cutting sharp corners and small graphics, which will affect the cutting quality.
Lead Settings
In the process of cutting thicker plates, in order to make the slits well connected and prevent burns at the beginning and end points, a transition line is often drawn at the beginning and end of the cutting, which are called lead and tail lines respectively. The lead and tail lines are important to the workpiece itself. It is useless, so it should be placed outside the category of workpieces, and at the same time, be careful not to set the leads at sharp corners and other places that are not easy to dissipate heat. The connection between the lead wire and the slit adopts a circular arc transition as much as possible to make the mechanical movement stable and avoid burns caused by corner stop.
Co-Edging
Two or more parts are co-edged into a combination, and a large number of regular graphics are co-edged as much as possible. Co-edging cutting can greatly shorten the cutting time and save raw materials.
Part Collision
In order to increase production efficiency, some metal laser cutters work 24 hours a day, and use unmanned automatic loading and unloading devices to hit the overturned parts after cutting, causing damage to the cutting head and interruption of manufacturing, causing great losses. When you need to sort, pay attention to the following three points:
• Choose a suitable cutting path, avoid the cut parts, and reduce collisions.
• Plan the cutting route reasonably to reduce the cutting time.
• Automatically or manually combine multiple small parts with micro-connections. After cutting, the removed parts can easily disconnect the micro-connections.
Safety Rules & Precautions
While enjoying the high-efficiency and beauty of laser metal cutting, how to do a good job of safety protection during use, so that the machine can perform better and reduce the radiation to the human body?
Check Before Operation
Whether the main controller casing, power supply casing, switching power supply casing, motor driver casing, data line casing, machine tool guide rail, motor casing, exhaust fan casing, and the main grounding point are well connected. Poor grounding will shorten the life span. High voltage discharge will damage the control circuit and even threaten life safety.
Be Careful When Handling
Light Path: When cutting and debugging the light path, please be careful not to let any part of the body touch the light path to avoid injury.
Energy: The magnitude of the laser current determines the magnitude of the energy, but when the current is greater than the allowable value, the energy will drop, and if the current exceeds the allowable value for a long time, it will greatly affect the service life.
Ambient Temperature: When the ambient temperature is higher than the maximum allowable value, the equipment will not get sufficient heat dissipation, which will reduce the operating stability of the equipment. When the ambient temperature is lower than the minimum allowable value, it may cause the water to freeze.
Cooling water temperature: When the cooling water temperature is greater than the maximum allowable value, the laser energy efficiency will drop rapidly. When the cooling water temperature is lower than the minimum allowable value, it will cause the water to freeze.
Ambient Humidity: Excessive humidity will cause high-voltage discharge, endangering personal safety, and will also cause damage to the power supply.
Power Supply: The fluctuation of the power supply voltage will cause the equipment to work unstable. If the voltage is too high, it will cause permanent damage to the power supply system of the equipment. In order to avoid the electrical appliances and circuits of the machine from being burned out due to excessive voltage, please install a power regulator of more than 2000W.
It’s Prohibited To Use In The Following Cases
Do not turn on the machine during severe weather such as thunder and lightning.
Untrained operators are not allowed to operate the machine alone.
Harm To Human Body And Protective Measures
Respiratory Tract Protection
The high temperature generated by the laser cooperates with the gas to complete various processing. At the same time, it also produces a large amount of dust, especially when processing some special metal materials. The generated dust contains some chemical components, which will cause harm to the human body if inhaled.
Therefore, when operating a metal laser cutter, attention should be paid to the protection of the respiratory tract. Install the supporting dust removal device, try to operate in an environment with unobstructed air, and wear a mask as much as possible. Do not touch the cut parts immediately to avoid scalding by residual heat.
Eye Protection
A laser metal cutter will cause damage to the retina or cornea of the eye when it is working. When arranging the cutting site, the following measures can be taken to reduce the reflection or radiation of ultraviolet rays:
• Darken the wall finish at the job site to reduce radiation.
• Install protective screens or curtains to reduce UV radiation.
• Wear protective dark-tinted eyes or goggles, or a welding cap to protect the eyes from the glare of the flame, ultraviolet and infrared rays from the plasma arc.
• Others in the working area should not look directly at the arc or flame during cutting.
Skin Protection
Laser cutting has certain damage to skin tissue, which can be repaired by itself. It should be noted that long-term exposure to laser beam may cause skin burns or leave scars. Therefore, when working with a laser metal cutter, the protection of the skin must also be given great attention.
For safety reasons, it is recommended that the operator wear long-sleeved clothes to prevent skin burns caused by direct laser radiation and prevent scalding caused by molten slag splashing on the skin. Do not touch the cut parts immediately, and wear gloves to avoid burns due to residual heat.
Care & Maintenance
In order to achieve a better operating state of the metal laser cutter, regular maintenance is also essential, and the following points should be paid attention to in maintenance:
• Daily cleaning is required to keep it clean and tidy.
• After the machine stops working, check whether the X, Y, and Z axes of the machine tool can return to the origin. If not, check whether the position of the origin switch is offset.
• The daily slag discharge drag chain needs to be cleaned.
• Clean up the sticky matter on the filter screen of the air outlet in time to ensure the smooth flow of the ventilation duct.
• The cutting nozzle needs to be cleaned every 1 hour of operation, and replaced every 2-3 months.
• Clean the focusing lens, keep the lens surface free of residue, and replace it every 2-3 months.
• Check the temperature of the cooling water, the temperature of the water inlet of the generator should be kept between 19°C and 22°C.
• Clean up the dust on the cooling fins of the water cooler and freeze dryer. To ensure the heat dissipation efficiency, the dust should be removed.
• Frequently inspect the working status of the voltage regulator to monitor whether the input and output voltages are normal.
• Monitor and check whether the switch of the mechanical shutter is normal.
• Auxiliary gas is output high-pressure gas, pay attention to the surrounding environment and personal safety when using the gas.
• Switching sequence:
Start-Up
Open air, water-cooled unit, cold dryer, air compressor, main engine, and generator should be baked for 10 minutes if conditions permit.
Shutdown
First press the high pressure, then the low pressure, and turn off the generator after the turbine stops rotating without sound. Followed by the water-cooled unit, air compressor, gas, cold dryer, machine power off can be left behind, and finally turn off the voltage stabilizer cabinet.
Buyer’s Guide
A laser metal cutter can come with a price from a few thousand to as much as ten thousand dollars. Therefore, it is never going to be an affordable option to pick up. To save your budget, you may think about picking up an affordable option, but do it only when you have enough knowledge about which one will be a good option and which one will not. In that case, choosing from a trusted manufacturer that will ensure good after-purchase support will be a better option to buy from. In case you face any difficulties after making the purchase, you will have the option to ask for help or support.
At the same time, check for all the technical issues that will allow the machine to work functionally well. In that case, the software should be compatible with the devices to which you will connect the machine.
