(Click 374 )

Fiber laser cutting machine is mainly composed of computer, laser, laser signal controller, laser cutting head, precision motion platform, precision rotating shaft, collet, chuck, numerical control system and laser micromachining software system. Each component is An integral part of fiber laser cutting machines. The laser cutting head is mainly composed of nozzle, focusing lens, focus tracking system, light guide focusing, water cooling, air blowing and mechanical adjustment parts. The laser cutting head is an essential workpiece for the laser cutting machine, which will be introduced in detail below.

Cutting head nozzle of fiber laser cutting machine: The form of the nozzle and the size of the nozzle determine the cutting quality. There are three types of nozzles: parallel type, convergent type, and cone type. There is also a kind of expanding nozzle in foreign countries that has good cutting characteristics. However, due to the complexity of the inner cavity of the nozzle, the processing technology and fineness are limited, it cannot be industrialized. Production.

Focusing lens of the cutting head of the fiber laser cutting machine: Laser cutting is to use the laser beam to focus through the lens to form a high-energy-density spot to achieve the purpose of laser cutting. Generally, the power density is the highest at the focal point. The longer the focal length of the lens, the larger the focal spot and the lower the power density, but the depth of focus is large and the operating tolerance is large. For example, the effective range of a 5-inch lens is greater than that of a 3-inch lens, so it is called a medium-telephoto lens. It is easy to understand that it is suitable for cutting thick plates. The requirement for the spacing stability of the tracking system is low, but the output power of the laser is high. The short-focus lens is only suitable for thin plate cutting below D3. The focal length has low requirements for the laser output power, and the requirement for the spacing stability of the tracking system is high.

Cutting head tracking system of fiber laser cutting machine: The focus tracking system is generally composed of a focus cutting head and a tracking sensor. The sensor is composed of a sensing element and an amplification control part. Depending on the sensing element, the tracking system is also different. Generally, there are two types of tracking systems, one is capacitive sensing element tracking system, also called non-contact tracking system, and the other is inductive sensor tracking system, also called contact tracking system.

As an essential part of fiber laser cutting machine cutting, the cutting head also determines the cutting quality of the product. Our company provides sample proofing service to ensure that the cutting needs are met, and then discuss cooperation, welcome to consult and understand!
