If you confirm your needs, you can go to do research on it. Maybe you can learn from your peers, and understand the machine functions and basic parameters. Select a few powerful manufacturers with favorable prices to conduct preliminary exchanges and proofing, and then conduct on-site investigations in the later stage, and conduct more detailed discussions on prices, online and offline training, and after-sales services.
Laser cutting machines can be classified as fiber laser machines or CO2 laser machines depending on their laser sources.
First of all, you need to consider some factors such as the scale of your business, what materials you need to cut, how thick the materials are, and then confirm the power supply and the size of the workbench according to your own needs. Currently, the laser powers in the market range from 80 watts to 40,000 watts, and the table size can be customized according to your requirements.
Laser cutting can only be done by using concentrated laser beams that produce high power density energy. Laser generators produce high-frequency pulsed lasers in pulsed fashion. The beam is transmitted, reflected and focused by a focusing lens group. A small, high energy-density spot of light is created on the part's surface. The focal point is near the surface to cut. The material melts immediately or vaporizes at a high temperature. Each laser pulse makes a small puncture in the substrate. The laser head and substrate move in a continuous, relative motion according to the programmed file.
Adjust the system parameters to cut the material according to its thickness and material.
With laser cutting, a laser beam is focused on the material through a nozzle’s hole, heating and melting the material. A cutting gas that flows coaxially through the nozzle removes the molten material.
The focus tracking system is composed of an auto focus laser head and a tracking sensor system. The cutting head is composed of mechanical adjustment parts, air blowing system, light guide system, and water cooling system. The sensor consists of amplification control part and sensing element. There are two types of tracking systems, one is an inductive sensor tracking system (also known as a contact tracking system), the other is the capacitive sensor tracking system (also known as the non-contact tracking system).
Choose your file, place your engraving material into the machine, close the door and press GO. The laser will take care of the rest.
A hybrid laser cutter is an affordable combined laser cutting system with fiber laser generator and CO2 laser generator all in one machine, as well as an automated power tool that uses a high-power CO2 laser tube to mix cutting metals and nonmetals, including steel, aluminum, brass, copper, titanium, iron, silver, gold, alloy, plywood, wood, MDF, acrylic, plastic, fabric, and leather. With fiber lasers, it can cut thicker metals, with CO2 lasers, it can cut thick nonmetals and thin metals. The hybrid laser cutting table fits 4x8, 5x10, and 6x12, which can be customized as your business plans. It's the best budget laser machine for hobby and commercial use.
You can adjust the system's cutting parameters based on the thickness and material of the raw material.
Several types of laser cutting machines are available, with each specific process producing parts with a high degree of precision, accuracy, and high-quality edge finishes. The laser cutting process generally results in less material contamination, physical damage, and waste compared with many other common cutting processes.
The beam emitted by the laser generator is focused by the optical path system into a laser beam of high power density. The beam is irradiated onto the surface of the part to bring the part to a melting point or boiling point, while the high-pressure gas coaxial with the beam blows away the molten or vaporized material. As the beam moves relative to the part, the material is slit finally, thereby achieving the purpose of cutting.
STJ1610M-2 cheap CO2 laser cutter for metal, acrylic, and wood with best budget adopts sealed CO2 glass laser tube, which is used for cutting thin metals (1.5mm SS and 2.5mm CS) and thick nonmetals (30mm acrylic sheet and 25mm wood panel).
The laser beam is focused to form a high density spot. The long and medium-focusing lenses are ideal for thick plate cutting. They also have very low spacing stability requirements. The short-focusing lens is suitable only for thin sheet cutters. It requires high spacing stability and reduces the power requirements.
Polycarbonate is an unsuitable material for laser cutting. ABS It emits cyanide gas and melts. ABS is difficult to cut with a laser cutter. It melts rather than vaporizes, and it is more likely to catch fire and leave melted gooey deposits on the vector cutting grid.
The laser beam is the most important component of the laser cutter; it determines wavelength and power, and thus the material that it can cut or engrave. Solid-state lasers, fiber lasers, and CO2 lasers are the three main types of lasers used in laser cutting.
