Laser cutting machine cutting process Disadvantages:
1. Laser cutting machine due to the limitation of laser power and equipment volume, laser cutting machine can only cut thick plate and thin plate, cutting speed with the increase of workpiece thickness and significantly reduced.
2. High cost of laser cutting equipment, one-time investment.
Laser cutting machine cutting process Process point
1. Mechanical structure design of laser cutting machine. This is mainly reflected in the design of beams and machine structures. The beams must be lightweight and flexible, and the machine structure requires high stiffness and stability. These are the basic elements to achieve high precision laser cutting.
2. Laser cutting machine NUMERICAL control technology. This requires a high quality control system. Good machine motion control performance at high speed and remote diagnosis and control.
3. High power laser beam transmission focusing technology. Beam quality is the key to laser cutting quality. Key technologies include: proprietary beam quality control, beam radius adjustment, beam compensation and video beam calibration systems.
4, laser cutting machine proprietary technology. These features include edge monitoring, capacitance height tracking, cut monitoring and penetration testing.
5. Laser cutting machine CAD/CAM software system. It is easy and smooth to program complex parts in order to coordinate with laser cutting graphics conversion, and it is also very convenient to edit and modify. It is necessary to develop and design special CAD/CAM software system.
6. High power laser cutting head design.
7. Laser cutting technology research, especially for curved surface cutting, titanium alloy cutting, thick plate cutting and other technology research.
Scope of application
Most laser cutting machines are controlled by CNC programs or made into cutting robots. As a complex processing method, laser cutting can cut almost any material, including 2D or 3D cutting of thin metal plates.
In the field of automobile manufacturing, the cutting technology of space curve such as roof window has been widely used. Volkswagen uses a 500W laser to cut complex body panels and various curved parts. In the aerospace industry, laser cutting technology is mainly used to cut special aerospace materials, such as titanium alloys, aluminum alloys, nickel alloys, chromium alloys, stainless steel, cerium oxide, composites, plastics, ceramics and quartz.
Laser cut aerospace components include engine flame tubes, titanium thin-wall machines, aircraft racks, titanium skin, wing tails, tailplates, helicopter main rotors, space shuttle ceramic heat insulation tiles, etc.
Laser cutting molding technology is also widely used in the field of non-metallic materials. It can not only cut high hardness and fragile materials, such as silicon nitride, ceramics, quartz, etc., but also can cut flexible materials, such as cloth, paper, plastic sheets, rubber, etc., such as clothing laser cutting, saving material 10% ~ 12%, efficiency increased by more than 3 times.
