What's the difference between laser marking machine
and laser engraving machine?With the development of laser technology, the types and performance of laser equipment are constantly improving and improving.Common laser equipment is laser engraving machine and laser marking machine.Both in the print of the media, product price, use range, product functions have some differences, for some new people often appear in this error.
So what is the difference between laser marking machine and laser engraving machine?
1. Different definitions: Laser engraving machine is a technological equipment that USES laser to carve the materials that need to be carved.Laser engraving machine can also be called laser cutting machine, laser cutting plotter, etc., will laser on wood products, acrylic, plastic board, metal board, stone and other almost all materials.
Laser marking machine is to use laser beam to make the evaporation of surface material to expose the deep material, leading to chemical changes and physical changes of surface material and carving marks, or to burn off part of the material through light energy, showing the graphic characters that need to be etched.
2. Different application materials: Laser engraving machine is generally used to carve or cut non-metallic materials, such as marble, wood, crystal, acrylic and so on.
Because laser marking machine does not need deep carving, it only realizes marking by marking identification and name. Most materials of metal and non-metal classes can be marked basically.
3, different depth and speed: laser engraving machine can be carved in large stroke size, but also can cut, the depth of far more than laser marking machine.
The speed of laser marking machine is relatively fast, generally up to 7000mm/ S4, the price is not the same: the price of laser marking machine due to different materials choose the corresponding model is not the same, tens of thousands to hundreds of thousands of.And nonmetal laser engraving cutting machine, the price of small power is relatively much cheaper laser marking machine.
Laser marking is the most common marking method in modern times.The manufacturing industry is deeply in love.With the development of technology and scientific progress, the range of laser marking machine is more and more wide, according to people's needs, can meet more and more requirements.Laser marking can be used in nonmetallic applications including plastics, silicon wafers, ceramics, rubber, etc.It can be used for small sizes of 70 * 70mm or for maximum sizes of 1500 * 1500mm.
Large surface marking machine is not only suitable for 300 * 300 ~ 600 * 600mm, but also for 400 * 400 ~ 800 * 800mm, and for 600 * 600 ~ 1500*1500mm.It is the same as optical fiber marking and CO2 marking. The laser wavelength is 1064mm, but the optical fiber and CO2 are relatively small in terms of laser power.The power of the large-format laser marking machine is generally 150W/180W/280W.The large-area dynamic focusing laser marking machine is suitable for marking, carving, hollowing and cutting of most non-metallic materials such as leather, cloth, wood, bamboo, paper, organic materials, etc.It is not satisfied by optical fiber marking and CO2 marking.The table of the large-format laser marking machine can realize its process in the range of 1500 * 1500mm at most.And meet the user's demand of high speed and precision.The maximum engraving speed of 10000mm/s is suitable for industrial mass production, which improves work efficiency more effectively.
What are the benefits of using laser to make marks on samples?Why do people continue to develop various types of laser marking equipment
to meet people's various types of needs?
If the mark will not fade due to environmental factors (touch, acid and reducing gas, high temperature, low temperature, etc.).
The marks carved by laser marking technology are not easy to copy and change, and to a certain extent have strong anti-counterfeiting.
Laser marking is processed with a non-mechanical light cutter, which can print marks on any regular or irregular surface, and the workpiece will not produce internal stress after marking, ensuring the original accuracy of the workpiece.No corrosion on the working surface, no tool wear, no toxicity, no pollution.
4. Wide applicability:
Laser can be used to process a variety of metal and non-metallic materials (aluminum, copper, iron, wood products, etc.)
5. High engraving accuracy:
The laser marking machine engraves fine lines, with the minimum line width up to 0.04mm.The marks are clear, lasting and beautiful.Laser marks can be used to print large amounts of data on very small plastic parts.For example, 2d bar codes that require greater precision and clarity can be printed, providing greater market competitiveness compared with imprinting or jet marking.
6. Low operating cost:
The marking speed is fast and the marking is formed once, and the energy consumption is small, so the operation cost is low.
7. High processing efficiency:
The marking process can be completed in seconds.
8. Fast development speed:
Due to the combination of laser technology and computer technology, users can realize laser printing output as long as they program on the computer, and can change the printing design at any time, fundamentally replacing the traditional mold making process.
Laser marking and the traditional mechanical engraving, chemical corrosion, screen printing, ink printing and other methods, with low cost, high flexibility, can be controlled by computer system, and laser action on the surface of the workpiece produced by the firm permanent marking is its outstanding characteristics.At present, in the marking printing industry, laser marking has occupied more than 90% of the market.Therefore, whether it is large-area dynamic focusing laser marking machine or optical fiber laser marking machine
or CO2 laser marking machine, it is a symbol of the development and progress of modern society and a breakthrough in a new field of laser industry.
