Abstract

The invention relates to a laser cutting machine. The laser cutting machine comprises a laser, a laser energy control system, an optical conduction system, a galvanometer scanning system and a laser focusing system, wherein the wavelength of laser emitted by the laser is between 490 and 580 nm; light beams emitted by the laser firstly pass through the energy control system, are reflected to the galvanometer scanning system through the optical conduction system and then are reflected to the laser focusing system to be focused into small light spots; and then the galvanometer scanning system utilizes the small light spots to cut a part to be cut. Compared with the prior art, the laser cutting machine utilizes the small light spots to cut the part to be cut, which can achieve the effects of high accuracy and high quality on the cutting of hard board materials.

Description

technical field [0001] The invention relates to a laser cutting machine. Background technique [0002] With the continuous expansion of the application fields of ceramics, stainless steel, aluminum alloy and other hard plate materials, the huge potential of laser in the processing of these materials is becoming increasingly apparent. Due to the inherent hard and brittle characteristics of ceramic materials and the stamping characteristics of stainless steel, aluminum alloy, etc., such products cannot be cut by die punching. Since laser cutting can quickly and accurately process hard plates into different shapes, the laser cutting process has become a research hotspot in the cutting industry of hard plates such as ceramics, stainless steel, and aluminum alloys. CO 2 Lasers are used to cut and process this type of product, but due to CO 2 The laser has the characteristics of long wavelength and large focused spot, so its cutting line width is wide, and the cutting edge is n...
