Laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporated to form holes. cut. Laser cutting is one of the thermal cutting methods.
Compared with traditional cutting methods such as plasma and flame, laser cutting is generally characterized by fast cutting speed and high quality.
Specifically summarized in the following aspects.
(1) Good cutting quality Due to the small laser spot, high energy density and fast cutting speed, laser cutting can obtain better cutting quality.
① The laser cutting incision is narrow, the two sides of the incision are parallel and perpendicular to the surface, and the dimensional accuracy of the cut parts can reach ±0.05mm. In terms of cutting accuracy, the plasma can reach within 1mm, and the laser can reach within 0.2mm. Therefore, the precision of the laser cutting machine is higher.
② The cutting surface is smooth and beautiful, and the surface roughness is only tens of microns. Even laser cutting can be used as the last process without machining, and the parts can be used directly.
(2) High cutting efficiency Due to the transmission characteristics of the laser, the laser cutting machine is generally equipped with multiple CNC workbenches, and the entire cutting process can be fully CNC controlled. During operation, only by changing the numerical control program, it can be applied to the cutting of parts of different shapes, both two-dimensional cutting and three-dimensional cutting can be realized.
⑶ fast cutting speed 10,000-watt power cutting thick plate, fast speed and high efficiency. The material does not need to be clamped and fixed during laser cutting, which not only saves tooling and fixtures, but also saves the auxiliary time for loading and unloading.
⑷ Non-contact cutting When laser cutting, the cutting torch has no contact with the workpiece, and there is no tool wear. To process parts of different shapes, there is no need to change the “tool”, just change the output parameters of the laser. The laser cutting process has low noise, small vibration and no pollution.
⑸ The types of cutting materials include carbon steel, stainless steel, galvanized sheet and other materials.
