1.What is CNC laser cutting machine?

  The CNC laser cutting machine also called the CNC laser cutter, laser cutter CNC, is a laser machine with CNC (Computer Numerical Control) system that uses a laser beam to cut material. The laser cutting machine focuses the laser light emitted by 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, and the high-pressure gas coaxial with the beam blows away the molten or vaporized material. As the relative position of the beam and the workpiece moves, the material will eventually form a slit, so as to achieve the purpose of cutting.

4. What are the main parts of CNC Laser cutter?

The laser cutting machine system generally consists of a laser generator, an (external) beam transmission component, a workbench (machine tool), a microcomputer numerical control cabinet, a cooler, and a computer (hardware and software).
1) . The main machine part of the machine tool: the machine part of the laser cutting machine, the mechanical part that realizes the movement of the X, Y, and Z axes, including the cutting work platform. It is used to place the workpiece to be cut and can move it correctly and accurately according to the control program, usually driven by a servo motor.
2) . Laser generator: a device that generates a laser light source. For the purpose of laser cutting, except for a few occasions where YAG solid-state lasers are used, most of them use CO2 gas lasers with higher electrical-optical conversion efficiency and higher output power. Because laser cutting requires high beam quality, not all lasers can be used for cutting. The Gaussian model is suitable for less than 1500W, low-order mode carbon dioxide lasers 100W-3000W, and multimode above 3000W.
3) . Outer optical path: Refractive mirror, used to guide the laser in the required direction. In order to prevent the beam path from malfunctioning, all mirrors must be protected by a protective cover, and a clean positive pressure protective gas should be introduced to protect the lens from contamination. A set of lenses with good performance will focus a beam with no divergence angle into an infinitely small spot. Generally, a lens with a focal length of 5.0 inches is used. The 7.5-inch lens is only used for thick materials >12mm.
4) . Numerical control system: control the machine tool to realize the movement of the X, Y, Z axis, and also control the output power of the laser.
5) . Regulated power supply: connected between the laser, CNC machine tool, and the power supply system. Mainly play a role in preventing interference from external power grids.
6) . Cutting head: It mainly includes parts such as a cavity, focusing lens holder, focusing lens, capacitive sensor, and auxiliary gas nozzle. The cutting head driving device is used to drive the cutting head to move along the Z-axis according to the program and is composed of a servo motor and a screw or gear and other transmission parts.
7) . Operating table: used to control the working process of the entire cutting device.
8) . Water chiller: used to cool the laser generator. A laser is a device that converts electrical energy into light energy. For example, the conversion rate of a CO2 gas laser is generally 20%, and the remaining energy is converted into heat. The cooling water takes away the excess heat to keep the laser generator working normally. The chiller also cools the external light path reflector and focusing mirror of the machine tool to ensure stable beam transmission quality and effectively prevent the lens from being deformed or broken due to excessive temperature.
9) . Gas cylinders: Including laser cutting machine working medium gas cylinders and auxiliary gas cylinders, used to supplement the industrial gas for laser oscillation and supply auxiliary gas for the cutting head.
10). Air compressor, air storage tank: provide and store compressed air.
11) . Air cooling dryer, filter: used to supply clean and dry air to the laser generator and beam path to keep the path and reflector working normally.

6. The advantages of fiber laser cutting machine

After so many years of development, the laser cutting machine has been applied to many fields by more and more people, and it has been loved by more and more people through its powerful working ability. It is more powerful than CNC engraving machines. Stronger, almost all materials can be processed, and the processing speed is faster, and the processing quality is higher. Then I will introduce you to the advantages of laser metal cutting machines.
1). High cutting accuracy: the laser cutting machine has a high cutting accuracy. The cutting gap produced is parallel to both sides and perpendicular to the surface. The dimensional accuracy of the cut parts can reach up to ±0.05mm, so the metal laser cutting machine can be used for processing Precision machinery and equipment, and it is controlled by a computer, capable of engraving or cutting different materials.
2). Fast cutting speed: The cutting speed of the laser cutting machine for metal is extremely fast. If the 1000w laser cutting machine is used to process 2mm thick steel plates, it only takes a few seconds to successfully process the steel plates. The maximum cutting speed can reach 1500mm/min, we can use a laser cutting machine to produce more products.
3). High cutting quality: The CNC laser cutting machine cuts the products with extremely high quality, almost no light spots and cutting marks, less debris generated by cutting smooth surface of the product, and higher aesthetics of the product.
4). It can effectively avoid tool wear: Because the CNC laser cutting machine is in the studio, it will not contact the workpiece, and the workpiece is processed by the laser beam. No matter what product is processed, there is no need to change the processing tool. The output power of the laser needs to be modified, so this can effectively avoid the loss of processing tools due to friction with the workpiece.
5). The processing process is environmentally friendly and sanitary: another advantage of using a laser cutting machine for processing is that it produces less pollution and is very safe, because the entire processing process is realized by a computer, and workers do not need to process manually, and laser cutting produces There is also very little waste material, which basically does not cause pollution.
