Part.one：Introduction and application of mixed cutting laser head

Mixing laser cutting head overview:

mixed cutting laser cutting head, also known as metal/metal laser cutting head, also known as follow-up laser cutting head, is an important part of the metal laser cutting machine.This kind of laser head is different from the common laser cutting head, which can cut both metal materials and non-metal materials.It is mainly used in the laser cutting machine with a small power below 500W. 1. With the capacitor setting system, the focus position of the metal plate can be accurately tracked, so as to cut the metal materials accurately.Mixed cutting laser cutting head in small and medium-sized power co2 laser cutting machine application has a strong advantage, the maximum support 500 w laser power, the structure of the double drawer, focal length is tie-in, can cut metal materials, can also be cutting nonmetal material, USES the focusing mirror air-cooled water cooling structure, can prevent: lens overheating, optimize focus lens installation drawer, positive focal length or negative focal length can be adjusted according to need, in order to achieve the best cutting effect.

1) principle: 
the laser beam enters the cavity of the mixed cutting laser head through the reflecting mirror, and through the focusing mirror, the energy of the laser beam is concentrated at a certain point, and the cutting effect is achieved by melting the surrounding material at high temperature to form machining marks.The mixed cutting laser cutting head and capacitance raising system cooperate with each other, moving the focusing mirror according to the fluctuation of the material surface, changing the position of the focus, so that the focus position is always kept at a certain distance from the plate surface, so as to accurately cut the metal.

2) components

1. The Z axis transmission

2. Three-dimensional mirror bracket

3. Focus lens cavity

4. Cutting nozzle

3) advantages :
1. With z-shaft drive, it can move up and down to accurately track the focus position.

2, the use of double drawer structure,K short focal length collocation, users can easily change different focal length of the compact lens, to achieve different material cutting, do not need to repeatedly proofread the focus position.

3, good air tightness, can withstand the metal cutting of high gas pressure.

4, the use of the cone form of cutting nozzle, gas out of the shape is conducive to the cutting of metal sheet.

5. The air cooled/water cooled structure of the focusing lens can prevent the lens from overheating.

4, the application industry can cut stainless steel, carbon steel, galvanized sheet and other metal materials, as well as acrylic, density board, wood, plastic, leather, cloth and other non-metallic materials.It is mainly used in rice gold processing, metal advertising word cutting, stainless
steel kitchenware processing, advertising industry, sheet metal cutting and other industries.
