The laser cutting machine can be seen in many places. What are its components? Next, listen to the detailed answers of the laser cutting machine manufacturers.
1、 Laser generator
A device that generates a laser light source. As far as the use of laser cutting is concerned, except for a few places where YAG solid state lasers are used, CO2 gas lasers and fiber lasers with high electro-optical conversion efficiency and high power output are mostly used. Because laser cutting requires high beam quality, not all lasers can be used for cutting.
2、 External optical path
Refractive mirror, used to guide the laser to the desired direction. In order to prevent the beam path from breaking down, all mirrors shall be maintained by the maintenance cover, and clean positive pressure maintenance gas shall be introduced to protect the lens from pollution. A set of lenses with good performance will focus a beam without divergence angle into an infinitely small spot.
3、 CNC system
Control the machine tool to complete the movement of X, Y, Z axes, and also control the output power of the laser. Stabilized voltage power supply: connected between laser, CNC machine tool and power supply system. It is mainly used to avoid interference from external power grid.
4、 Cutting head
It mainly includes cavity, focusing lens base, focusing mirror, capacitive sensor, auxiliary gas nozzle and other parts. The cutting head drive installation is used to drive the cutting head to move along the Z axis according to the program. It is composed of servo motor, screw rod or gear and other transmission parts.
5、 Machine host part
Laser cutting machine tool part, the mechanical part that completes the movement of X, Y, Z axes, including the cutting platform. It is used to place the workpiece to be cut and stop moving correctly and accurately according to the control program, usually driven by a servo motor.
Regular maintenance is essential for the laser cutting machine, because it can keep the laser cutting machine in good condition during operation. In order to better use and maintain the laser cutting machine, let's follow the laser cutting machine manufacturer to find out what needs to be paid attention to when maintaining the laser cutting machine.
1、 Check the straightness of the track and the perpendicularity of the machine every six months, and timely maintain and debug in case of any abnormality. Otherwise, the cutting effect may be affected, the error will increase, and the cutting quality will decline.
2、 Check the steel strip frequently to ensure that it is tight. Otherwise, if there is a problem in the operation, people may be injured. The steel belt looks inconspicuous, but when it goes wrong, it should not be underestimated.
3、 Use a vacuum cleaner once a week to remove the dust and dirt in the machine, and all electrical cabinets should be tightly closed to prevent dust.
4、 All guide rails shall be cleaned regularly to remove dust and other sundries to ensure normal operation of equipment. The rack shall be wiped frequently and lubricated to ensure lubrication without sundries. The guide rail and motor shall be cleaned and lubricated frequently, so that the machine can move better and cut more accurately when moving, and the quality of the cut products will be improved.
5、 The double focus laser cutting head is a vulnerable item on the laser cutting machine. Long term use may cause damage to the laser cutting head.
