Increase knowledge: How does the laser cutting machine work?
Laser cutting machine is an essential equipment for modern manufacturing industry, which improves processing efficiency and accuracy, occupies an important position in metal processing, and has revolutionized the manufacturing industry. It is fast, efficient and accurate, although the process of laser cutting is simple, it involves several key elements, and the internal parts of the machine must cooperate with each other to achieve accurate results.
In this article, we will explore how laser cutting machines work, as well as other trivia.
How does the laser cutting machine work?
Laser cutting machines convert laser energy by focusing laser beams into heat so high that it melts or vaporizes metal. When the laser beam passes through the material, it forms a thin line on the metal surface, and the temperature of the production line is high enough to cut the material, and by controlling the movement of the cutting head, the cutting of complex shapes can be completed.
The laser cutting process involves a series of steps：
The first stage is to prepare the material to be cut.
This may involve cleaning the surface, masking the material to protect areas that do not need cutting, and setting up the material in the laser cutter.
The second stage is to install the laser cutting machine.
This involves selecting the right laser source and optics to achieve the desired cutting depth and precision, and then using a series of lenses and mirrors to focus the laser beam on the material for the best cutting results.
The third stage is the actual laser cutting process.
When the laser beam is focused on the material, it generates high levels of heat, which then melts, burns or vaporizes the material, leaving a precise cut. The laser cutter follows a pre-determined path and is guided by a computer program or CNC system to create the desired shape or design.
What are the key factors of laser cutting?
Laser cutting is the process of making precise cuts to materials using high-power lasers, a popular method for cutting and etching a variety of materials, including metal, wood, plastic, and glass. The laser cutting process uses a focused beam of light to melt, burn, or vaporize the material, leaving a clean and precise cut.
The first key factor in laser cutting is the laser itself.
A laser is a highly focused beam of light produced when energy is acted on a gas or crystal, and the laser beam is then focused and directed at the material to be cut. The laser beam can be adjusted to suit the material being cut, enabling clean and precise cutting.
The second important component of laser cutting is the cutting bed.
It is a flat surface on which the material is placed for cutting, the cutting bed is usually made of a material that can withstand the intense heat generated by the laser, the material to be cut is placed on the bed, and the laser beam is directed at the material.
The next key element is computer numerical control (CNC) systems.
The CNC system converts design information from computer-aided design (CAD) software into machine instructions to guide the laser cutting machine. The numerical control system ensures that the laser beam follows the desired path, cutting the material to the exact dimensions required for the design.
Laser cutting offers several advantages over traditional cutting methods, including higher accuracy, speed and versatility. The laser beam is very accurate, which means that the finished product will be precise, without rough edges, and at the same time, the speed of laser cutting is also faster than other cutting methods, which can save a lot of time and cost for manufacturers. In addition, laser cutting is versatile and can cut a variety of materials, including metal, plastic and wood.
The specific advantages of laser cutting machine:
1 high precision: suitable for cutting precision accessories and fine cutting of various craft words and pictures.
2 fast speed: more than 100 times of wire cutting.
3 slight influence: the heat affected zone is small, not easy to deformation. The slit is smooth and beautiful, and no post-processing is required.
4 high cost performance: the price is only 1/3 of the similar performance of CO2 laser cutting machine, and 2/5 of the same effect CNC punching machine.
5 Use cost low: only 1/8 to 1/10 of the same type of CO2 laser laser cutting machine, the cost per hour is only about 18 yuan, and the cost per hour of CO2 laser cutting machine is about 150 to 180 yuan.
6 follow-up maintenance cost low: only 1/10 to 1/15 of the similar CO2 laser cutting machine, and 1/3 to 1/4 of the same effect CNC punching machine.
7 stable performance：to ensure continuous production. Solid YAG laser is one of the most stable and mature products in the laser field.
Fiber laser cutting machine five use skills：
1)
Dual focal length laser cutting head is a vulnerable item on the laser cutting machine, long-term use, resulting in damage to the laser cutting head.
2)
Check the straightness of the fiber laser cutting machine track and the perpendicularity of the machine every six months, and maintain and debug in time if found abnormal.
3)
Once a week, use a vacuum cleaner to absorb the dust and dirt in the machine, and all electrical cabinets should be closed to prevent dust.
4)
Often check the fiber laser cutting machine steel strip, be sure to tighten. Otherwise, if there is a problem in operation, it may hurt people, and seriously it can lead to death.
5)
The guide rail of the fiber laser cutting machine should be regularly cleaned to remove dust and other debris, to ensure that the normal rack of the equipment should be wiped frequently, and lubricating oil should be added to ensure lubrication without debris. The guide rail should be cleaned and lubricating often, and the motor should also be cleaned and lubricating often, the machine can be better positioned in the process, more accurate cutting, and the quality of the cut product will be improved
Compared to traditional cutting machines, laser cutting machines are able to cut a variety of designs with greater precision and accuracy. Because laser cutters can be completely controlled by CNC, they can repeatedly and consistently produce complex parts with high tolerances. In addition, laser cutting can also produce high-quality cuts and edges, with a higher level of safe operation. In short, with the continuous development of laser technology, the application of laser cutting machine in industry will be more and more, and the choice of the right industrial laser machine will directly affect your production results.
