The choice of nozzle form and nozzle size has a great influence on cutting quality. There are three main types of nozzles: parallel, convergent and conical. To use the energy of the laser beam to cut, the original beam emitted by the laser must be focused through a lens to form a high-energy-density light spot. According to Gaussian optics theory, 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 greater the focal depth (the focal depth refers to the distance between the two spots with a 5% change in diameter on both sides of the focal point, which is also called the effective cutting range during cutting), and the operating tolerance Big. The focus tracking system of a laser cutting machine is generally composed of a focus cutting head and a tracking sensor system. The cutting head includes light guide focusing, water cooling, air blowing and mechanical adjustment parts; the sensor is composed of sensing elements and amplifying control parts. The tracking system is completely different according to the different sensing elements. Here, there are mainly two types of tracking systems, one is the capacitive sensor tracking system, also known as the non-contact tracking system. The other is an inductive sensor tracking system, also known as a contact tracking system. Features Fiber Laser Cutting Head has a QBH optical fiber interface and a high-precision collimation adjustment unit. An observation window has also been added, making it easier and more direct to observe the focal length. The electroplating imitates the surface of stainless steel, which has good conductivity and can enhance the sensitivity of the height adjustment device. The effective water cooling protection of the focal lens makes the operation safer and greatly improves the service life of the focal lens. Using precision fine-tuning wheel, the dimming is convenient and accurate.

For the outside, we adopt carton box. In the middle, the fiber laser cutting head is covered by foam, to protect the fiber laser cutting head from shaking. For the inside layer, the fiber laser cutting head is covered by waterproof plastic bag. Q: What's delivery time? A: Generally speaking, lead time is 3-5 working days after receive the payment.Laser Cutting Head website:http://www.kinglasers.com/laser-cutting-machine-accessories/laser-cutting-head/
