What is 2KW Laser Cutting Machine
The laser cutting machine emits a high powered laser beam to either cleanly cut or etch a specific design on materials such as steel, plastic or wood. It is generally used more for industrial manufacturing applications and the beam will either burn, vaporise or melt away the excess product, leaving a superior finished design or edge.A laser cutting machine has settings known as the computer numerical control (CNC), as well as laser optics, which control and direct the laser beam's intensity for the desired design effect, or the specific cuts required in a manufacturing or design project.
Advantages of 2KW Laser Cutting Machine
High Precision
The narrowness of the energy beam and the precision with which the material and/or the laser optics can be moved ensures extremely high cutting quality. Laser cutting machine allows the execution of intricate designs that can be cut at high feed rates, even in difficult or fragile material substrates.
Variety of Materials
Laser cutting machine is a flexible technology that can be adapted to cut widely different materials efficiently, including: acrylic and other polymers, stainless steel, mild steel, titanium, hastelloy, and tungsten. This versatility is increasing as technology develops.
High Speed
Few production methods can come close in processing speed to laser cutting machine. The ability to cut a 40 mm steel sheet using a 12 kW oxygen-assisted laser provides speeds some 10x faster than a bandsaw and 50–100 times faster than wire cutting.
Unlimited 2D Complexity
Laser cutting machine allows intricacy through the nature of the G-code movement control method of positioning and the small size of the applied energy hot spot. Features that are only weakly attached to the main body are cut without any application of force, so the process is essentially limited by material properties, rather than process capabilities.
Acrylic (PMMA)
Acrylic produces a smooth cutting edge but an exhaust system is required due to the flammable vapors generated. The gas pressure must be set so that it blows away the vapors while also cooling the cut edge to solidify it. Excessive air pressure will distort the cut edge while it is still molten. Acrylic is also known by the trade name of Perspex® or by its chemical name polymethyl methacrylate.
Carbon Steel/Mild Steel
Carbon steel is a term used to describe a wide range of steels with varying amounts of carbon as their main alloying element. Mild steel is also another type of carbon steel with a carbon percentage of less than 0.3 %. The higher the carbon content the stronger the steel. High-power lasers can cut up to 20–25 mm plate thickness.
Stainless Steel
Stainless steel is classified as a steel alloy containing chromium and/or nickel as its main alloying elements. Stainless steels are resistant to a wide range of chemicals. Stainless steels are readily cut on any laser cutting technology. However, fiber lasers are better suited for cutting stainless steel.
Aluminum
Aluminum is a blanket term used to describe a range of aluminum alloys with different alloying elements and applications. Aluminum has a good strength-to-weight ratio and as such is often used in aerospace applications. Aluminum is a reflective material when melted, making it relatively difficult to cut. While it is possible to cut aluminum with a CO2 laser, it is better to make use of a fiber laser for aluminum cutting.
Brass
Brass is an alloy of copper and zinc with some secondary alloying elements. Brass is corrosion resistant, electrically conductive, and has low friction. Typical applications include low-friction bushes and electrical applications.
Wood
Wood is readily cut with relatively low power (150–800 W) CO2 lasers. However, it is important to have an exhaust system as smoke is generated when laser cutting wood. Natural woods have a grain structure which can result in inconsistent finishes when engraving or cutting. Hardwoods and softwoods can be laser cut.
Hardboard
Hardboard is similar to MDF (Medium Density Fiberboard) but is denser, making it a stronger, more robust choice. The wood fibers are bonded with an adhesive. During cutting, this glue is vaporized. This releases dangerous fumes which require the use of an exhaust system. Hardboard is homogenous, meaning that cutting and engraving are consistent.
Cork
Cork is a soft wooden material that comes from the bark of the cork oak tree and is often used as shoe inserts, non-slip coaster bases, and pinboards. Cork can be laser cut and engraved very easily.
Leather
Leather is a hard-wearing, strong natural material used for shoes, belts, and wallets. Leather can be easily laser-cut and engraved and has high perceived value, especially when used to create personalized laser-cut items. There are also synthetic versions of leather called faux leather. However, some of these may contain PVC which produces corrosive vapors when laser cut.
Felt
Felt is a low-cost, non-woven fabric that is difficult to hand cut but cuts very easily with a laser cutter. Felt can be used for garments, decorative patches, and place mats. It is recommended to use 95–100 % wool felt, as synthetic felt is often made from acrylic and cuts very poorly.
How Does Laser Cutting Machine Work
Beam Generation
The laser beam is a column of very high-intensity light, of a single wavelength, or color. In the case of a typical CO2 laser, that wavelength is in the Infra-Red part of the light spectrum, so it is invisible to the human eye. The beam is only about 3/4 of an inch in diameter as it travels from the laser resonator, which creates the beam, through the machine's beam path. It may be bounced in different directions by several mirrors, or "beam benders" before it is finally focused onto the plate. The focused laser beam goes through the bore of a nozzle right before it hits the plate. Also flowing through that nozzle bore is a compressed gas, such as Oxygen or Nitrogen.
Beam Focusing
Focusing the laser beam can be done by a special lens, or by a curved mirror, and this takes place in the laser cutting head. The beam has to be precisely focused so that the shape of the focus spot and the density of the energy in that spot is perfectly round and consistent, and centered in the nozzle. By focusing the large beam down to a single pinpoint, the heat density at that spot is extreme. Think about using a magnifying glass to focus the sun's rays onto a leaf, and how that can start a fire. Now think about focusing 6 KWatts of energy into a single spot, and you can imagine how hot that spot will get.
Localized Heating
The high power density results in rapid heating, melting and partial or complete vaporizing of the material. When cutting mild steel, the heat of the laser beam is enough to start a typical "oxy-fuel" burning process, and the laser cutting gas will be pure oxygen, just like an oxy-fuel torch. When cutting stainless steel or aluminum, the laser beam simply melts the material, and high-pressure nitrogen is used to blow the molten metal out of the kerf.
Beam Movement
On a CNC laser cutter, the laser cutting head is moved over the metal plate in the shape of the desired part, thus cutting the part out of the plate. A capacitive height control system maintains an exactly accurate distance between the end of the nozzle and the plate that is being cut. This distance is important because it determines where the focal point is relative to the surface of the plate. Cut quality can be affected by raising or lowering the focal point from just above the surface of the plate, at the surface, or just below the surface.

Types of Motors Used Laser Cutting Machine
Servo Motors
Servo motors are commonly used in high-precision applications due to their ability to provide precise control over position, speed, and torque. Servo motors are known for their accuracy and responsiveness, making them ideal for intricate and detailed cutting tasks.
They are equipped with feedback systems, such as encoders, which continuously monitor the motor's position and adjust accordingly to maintain precision.
Stepper Motors
Stepper motors are often used in less demanding applications. They move in discrete steps, which allows for good control over position but may lack the speed and precision of servo motors.
Stepper motors are typically more affordable and simpler to use, making them suitable for entry-level laser cutting machines. However, they do not have feedback systems, which can result in missed steps and reduced accuracy under high-speed or high-load conditions.
Several Core Components of Laser Cutting Machine
Fiber laser
Laser is the core "power source" in laser equipment. Like car engine, it is also a relatively expensive part of fiber laser cutting machine.
Cutting head
The cutting head is the laser output device of the fiber laser cutting machine, which consists of a nozzle, a focus lens and a focus tracking system. The cutting head of the laser cutting machine travels according to the set cutting track, but the height of the laser cutting head needs to be adjusted and controlled according to different materials, thicknesses and cutting methods.
CNC system
The control system is the main operating system of the fiber laser cutting machine. It mainly controls the machine tool to realize the movement of X, Y, Z axis, and at the same time controls the output power of the laser. Its quality determines the stability of the working performance of the fiber laser cutting machine. Through the accurate control of the software, the cutting accuracy and cutting effect can be effectively improved.
Motor
The motor of the laser cutting machine is the core part of the motion system. The performance of the motor directly affects the processing effect and production efficiency of the product. At present, the commonly used motors include stepper motors and servo motors. According to the type of industry and product type to be processed, a suitable motor is configured.
●Stepper motor
Fast start-up speed and sensitive response, suitable for engraving and cutting processing with low requirements. There are many brands of stepper motors with different performances.
●Servo motor
Fast speed, smooth movement, high load, stable performance; smooth cutting edge of processed products, fast cutting speed; high price, suitable for industries and products with high processing requirements.
Machine tool
Fiber laser cutting machines have high requirements for the stability of the machine tool. High-precision, high-stability machine tools help improve the accuracy of laser cutting. At present, the mainstream machine tools on the market include gantry type, cantilever type, beam type, etc. Different machine tools have different functions. For example, beam machine tools are mainly used for material cutting in large manufacturing companies, and can also be used for model cutting in specific fields, such as 3D fiber laser cutting, which is mainly used in the automotive industry.
Laser lens
Many optical devices have laser lenses. Different lenses have different functions, including full mirror, half mirror, focusing lens, etc. The quality of the lens directly affects the output power of the laser and the performance of the whole machine.
Cleaning the Machine
Dust and debris are inevitable in any machine, including laser cutting machines. Regularly cleaning your machine, both inside and out, is essential for optimal performance. Pay special attention to the inside of the machine cabinet, the bed, and any areas where materials may accumulate. Use a soft brush or cloth to remove any dust or debris, making sure not to scratch any surfaces.
Checking and Cleaning the Fan Unit
The fan unit plays a crucial role in removing fumes and smoke generated during the laser cutting process. Regularly check the fan unit for any accumulation of dust and debris that can impede its function. Disconnect the fan unit from the electrical supply, remove the extraction hoses, and clean the impeller fan and ducting using a soft paintbrush. This will ensure proper airflow and prevent overheating.
Inspecting and Lubricating Runners
To ensure smooth operation, regularly inspect and lubricate the runners and the rise and fall of the bed using light oil. Friction can cause wear on moving components, so keeping them lubricated is important for longevity and performance.
Checking and Maintaining the Air-Assist Compressor
The air-assist compressor helps remove debris from the cutting area, ensuring clean and accurate cuts. Check the compressor for correct operation and any obstructions in the filtration elements. Inspect the delivery hose from the compressor to the cutting head to ensure a suitable supply of air is reaching the nozzle.
Monitoring Optics
Dirty optics can significantly reduce the beam's strength and affect the quality of your cuts. Regularly inspect the optics for any dirt or residue. If necessary, clean them using an appropriate cleaning solution and gentle cotton buds. Be careful not to damage the optics during the cleaning process.
Maintaining the Chiller
The chiller is responsible for cooling the laser tube and maintaining the optimal temperature. Regularly monitor the chiller's performance and check for any temperature indications on the display. Every few weeks, clean the filters in the chiller and remove any buildup of material. Ensure that you use deionized or distilled water to prevent impurities from clogging the system.
