The price of laser cutting machines is generally around 100000 to 400000 yuan.
Laser cutting is achieved by utilizing the high power density energy generated by laser focusing.
Under the control of a computer, the laser emits controlled repetitive high-frequency pulses through pulse discharge, forming a beam of light with a certain frequency and pulse width.
The pulsed laser beam is transmitted and reflected through the optical path, and is focused on the surface of the processed object through a focusing lens group, forming subtle high-energy density light spots. The focal point is located near the surface to be machined and melts or vaporizes at instantaneous high temperatures.
There are two types of laser cutting techniques: one is pulse laser suitable for metal materials. The second is that continuous laser is suitable for non-metallic materials, which is an important application field of laser cutting technology.
During the cutting process, auxiliary steam suitable for cutting materials was also added. During the steel cutting process, oxygen acts as an auxiliary steam and produces exothermic chemical reactions with molten metal to oxidize the material, helping to blow away the slag in the cutting seam. How to set the cutting speed of the fiber laser cutting machine.
Compressed air is used for cutting polypropylene plastic, while inert vapor is used for cutting flammable materials such as cotton and paper. The auxiliary vapor entering the nozzle can also cool the focusing lens, preventing smoke from contaminating the lens base and causing the lens to overheat.
