Principle of action
- Laser engraving machine: Use laser beam to corrode, evaporate, melt, etc. the workpiece, and remove part of the material on or inside the material according to the preset pattern or text, forming an engraving effect with a certain depth and shape.
- Laser cutting machine: A high-energy-density laser beam irradiates the surface of the material to quickly melt or vaporize the material. At the same time, through the motion control of the machine tool, the laser beam moves along the predetermined cutting path, thereby cutting the material into the desired shape.
- Laser marking machine: A high-energy laser beam irradiates the surface of an object, and the light energy instantly changes into heat energy, causing rapid evaporation or physical or chemical changes on the surface of the object, and engraving text, images or logos on the surface.
Similarities
- Principle basis: They are all based on laser technology, using lasers to generate high-energy, monochromatic, unidirectional and coherent laser beams.
- Processing characteristics: All are non-contact processing, which will not cause mechanical stress or deformation on the workpiece. It can process a variety of materials, including metals and non-metals.
- Control method: Usually operated by a computer control system, graphics, text and other instructions can be input through software to accurately control the movement trajectory and processing parameters of the laser beam.
Differences
- Processing depth: Laser engraving machines can engrave materials to a certain depth; laser cutting machines have high energy and can completely cut through plates and other materials; laser marking machines only produce shallow marks on the surface of materials.
- Processing speed: Laser marking machines are usually the fastest, laser cutting machines are moderately fast, and laser engraving machines are relatively slow.
- Processing accuracy: Laser marking machines have high accuracy and can achieve fine markings; laser cutting machine accuracy can meet general cutting needs; laser engraving machine accuracy is slightly lower than marking machines due to factors such as engraving depth.
- Working area: The working area of laser marking machines is generally small; laser engraving machines and cutting machines can achieve large-format processing depending on the model.
- Laser type: Laser engraving machines commonly use carbon dioxide glass tube lasers; laser cutting machines include YAG laser cutting machines, fiber laser cutting machines, etc.; laser marking machines include semiconductor, carbon dioxide, optical fiber, ultraviolet laser marking machines, etc.
Application scope
- Laser engraving machine: used in the handicraft industry to engrave wood, jade, crystal and other handicrafts; in the advertising industry to engrave acrylic, two-color boards, etc. to make plaques; in the leather and clothing industry to engrave leather patterns.
- Laser cutting machine: used in the metal processing industry to cut various metal sheets; used in the automobile manufacturing industry to cut auto parts; used in the aerospace field to cut aviation materials.
- Laser marking machine: used in the electronics industry to mark model numbers, QR codes, etc. on the surface of electronic components; in automobile manufacturing, used to mark auto parts numbers and traceability codes; in the food and drug industry, used to mark production dates, batches, etc. on packaging.
