What is a CNC laser cutting machine: Introduction to laser cutting machines

What is a CNC laser cutting machine? It is a kind of machine tool developed by using laser light to cut, engrave, cut, drill, and mark various materials that are difficult to process with traditional blades and knives. It is mainly used for more refined cutting and processing.

Because the blade and other parts in contact with the material are not used, in addition to the laser oscillator has a certain life span, no Wearable parts such as worn or aged contact parts need to be replaced. In addition, due to the non-contact processing, the processed material will not be deformed due to stress or pressure during the processing, and the data is directly transmitted to the processing machine with the image processing software. In this way, the mold manufacturing process itself required in the past is omitted, and a variety of products can be processed. This system is suitable for processing two-dimensional shapes such as medium density fiberboard (MDF) and metal plates, because the processing of three-dimensional shapes is more difficult. YAG and CO2 lasers were once mainstream lasers, but the proportion of fiber lasers and high-power semiconductor lasers is increasing.

When using invisible lasers such as YAG and CO2 lasers, there is a danger of blindness due to the carelessness of the operator during the processing. Therefore, there is an openable and closeable device between the processing area and the operator. Laser cutting machines for doors and laser cutting machines equipped with fire-sensing alarms that can detect abnormal flames or heat in the processing area and send out danger alarms to the operator are becoming more and more safe. .

The large-scale laser processing equipment specially used for metal processing can perform refined laser cutting, but this equipment is relatively expensive both in initial cost and operating cost, which may cause a surge in manufacturing costs. Depending on the application The traditional metal processing method may be cheaper. Due to the lack of human resources such as operators, the introduction of such equipment may be very expensive.

Many small and medium-sized laser cutting machine manufacturers cannot process metals, but they specialize in processing various materials. The laser oscillators they use are sealed with mixed gas, which has a high operating cost. Some manufacturers use accessory laser oscillators so that the operator can easily replace the system without the assistance of professional technicians.

In addition, before about 2015, even for low-priced models, the installation cost per unit is also very high, but the high-power semiconductor lasers that can greatly simplify the light guide optical system are getting cheaper and cheaper in recent years. In the future, low-cost devices for individuals have also begun to be sold.
