One, laser generator
A device used to generate a laser source. As far as the use of laser cutting machines is concerned, except for the YAG solid-state lasers used in a few places, most places use CO2 gas lasers and fiber lasers with high electro-optical conversion efficiency and high output power. Because laser cutting requires high beam quality, not all lasers can be used for cutting.
Second,Outer Optical Path
Refractor, used to guide the laser in the desired direction. In order to prevent the beam path from being interrupted, all mirrors should be maintained with a maintenance cover and a clean positive pressure maintenance gas should be introduced to prevent the lens from being contaminated. A set of lenses with good performance will focus the beam with no divergence angle into an infinitely small spot.
Three, CNC system
Control the machine tool to complete the movement of the X, Y, Z axis, and also control the output power of the laser cut machine metal cutting. The stabilized power supply is connected between the laser, CNC machine tool and the power supply system. The main purpose is to avoid interference from external power grids.
Four, cutting head
It mainly includes a cavity, a focusing lens holder, a focusing lens, a capacitance sensor and an auxiliary gas nozzle. The cutting head driving device is used to drive the cutting head to move along the Z axis according to the program, and is composed of a knife holder motor and a screw or gear and other transmission components.
Five, machine tool host
2000w Laser cutting machine tool part, the mechanical part that completes X, Y, Z axis movement, including the cutting table. It is used to place the workpiece to be cut, and can stop the movement correctly and accurately according to the control program, usually driven by the tool post motor.
The above is the composition of the various parts of the laser cutting machine. Reasonable use of the equipment can extend its service life.
