What are the important accessories of laser cutting machines?
A laser cutting machine is mainly a combination of the body, light, and electricity. The entire machine mainly consists of three parts: the body frame part (mechanical part), the laser, the laser head, the motion system, and the operation console (electrical control part). In addition, it is equipped with laser cutting auxiliary equipment: a stabilized power supply (required to be used in conjunction with the laser tube), a chiller unit (used for cooling the machine, which can extend its service life), an air compressor The cooling dryer, filter, exhaust dust collector, slag extractor, etc. constitute the system integration of the entire set of equipment.
The functions of each part of the laser cutting machine are as follows:
1. Machine frame part (mechanical part): The machine tool part of the laser cutting machine, which is the mechanical part that realizes the movement of the X, Y, and Z axes, including the cutting work platform. Used to place the cut workpiece and move it correctly and accurately according to the control program, usually driven by a three-phase stepper motor.
2. Laser: A device that generates a laser light source.
3. External optical path: a refracting mirror used to guide the laser in the desired direction. To ensure that the beam path does not malfunction, all mirrors should be protected by protective covers and clean positive pressure protective gas should be introduced to protect the lenses from contamination.
4. Motion system: Control the machine tool to achieve X, Y, and Z axis motion, while also controlling the output power of the laser.
5. Stabilized power supply: connected between the laser, CNC machine tool, and power supply system. Mainly used to prevent interference from external power grids.
6. Cutting head: mainly includes components such as cavity, focusing lens seat, focusing mirror, capacitive sensor, and auxiliary gas nozzle. Cutting head drive
7. The device is used to drive the cutting head along the Z-axis direction according to the program, and is composed of a servo motor and transmission components such as screws or gears.
8. Operation console: used to control the working process of the entire cutting device.
9. Water chiller: used to cool laser tubes. A laser tube is a device that converts electrical energy into light energy. For example, a CO2 gas laser typically has a conversion rate of 20%, and the remaining energy is converted into heat. Cooling water takes away excess heat to maintain the normal operation of the laser generator. The chiller also cools the external light path reflector and focusing mirror of the machine tool to ensure stable beam transmission quality and effectively prevent deformation or cracking caused by excessively high lens temperature.
