10 Most Popular Laser Engraving Machines for Metal

What Is It?

Metal laser engraver is a type of CNC laser marking system with fiber laser source for 2D/3D metal engraving on stainless steel, carbon steel, aluminum, galvanized steel, silver, alloy, gold, copper, titanium, iron and brass. Metal laser engravers can make 2D laser engraving, color laser engraving, rotary laser engraving, online flying laser engraving, deep laser engraving and 3D laser engraving on metal surface. CNC laser metal engraving machine uses the ligh beam to remove the specific part of the metal material, so as to achieve the desired effect or mark. In metal engraving applications, the laser beam is like a chisel used in CNC engraving, chiseling away excess metal material. A laser engraver is the best way to engrave metals without tools.

How Does It Work?

Metal laser engraving machines use MOPA fiber laser source for color engraving on stainless steel and titanium, and use rotary device for engraving on rings, bracelets and bangles jewelry, and use online flying system for mass production with continuous manufacturing process, and use high laser power for deep engraving on metal, and use 3D system for engraving on aspheric surface, angular surface, rollers, pipes, cylinders and most curved surface.

What Is It Used For?

Laser metal engravers are used for engraving, etching or marking on stainless steel, aluminum alloy, alumina, tungsten steel, zinc alloy, titanium alloy, gold, silver, copper, iron, bamboo products, leather products, plastics, silica gel, paper, acrylic, glass, ceramics, jade, porcelain, PC board, PU and other materials.

Laser metal engraving machines are applied in electronic components, hardware products, tool accessories, integrated circuits (IC), electrical appliances, mobile communications, precision equipment, glasses and watches, jewelry, auto parts, plastic buttons, building materials, PVC pipes, PPR Pipe, medical equipment and other industries.

Technical Parameters

Pros & Cons

Compared with traditional mechanical metal engraving, laser engraver has many advantages in metal fabrication:

1. Laser metal engraving does not need to contact the engraved workpiece, so many fixtures and tools are omitted, and the workpiece will not generate internal stress after engraving, ensuring the original accuracy of the workpiece.

2. No corrosion to the working surface, no "tool" wear, no poison, no pollution.

3. The high-precision characteristics of laser engraving are also particularly suitable for the processing of complex graphics.

4. The mark will not fade due to environmental relations (touch, acid and reduced gas, high temperature, low temperature, etc.), and it has high anti-counterfeiting.

5. Non-contact: Laser metal engraving is processed by a non-mechanical "light knife", which can print marks on any regular or irregular surface.

6. Low operating cost: The engraving speed is fast and the engraving is formed at one time, with low energy consumption and low operating cost. Although the equipment investment of the laser metal marking machine is larger than that of the traditional engraving tools, from the operating cost, the use of the laser metal etching machine is much lower.

Features

Laser metal engraving machine uses a light beam to make permanent marks on the surface of various materials. The effect of engraving is to expose deep material through the evaporation of surface material, or to engrave traces by light energy causing chemical and physical changes on the surface material, or to burn off part of the metal material through light energy to show the text or pattern to be etched.

1. It can process most metal or non-metal materials.

2. The laser is processed with non-mechanical "tools", which does not produce mechanical extrusion or mechanical stress on the material, has no "tool" wear, is non-toxic and rarely causes environmental pollution.

3. The laser beam is very thin, so that the consumption of the processed material is small.

4. During engraving, it will not generate X-rays like electron beam bombardment and other processing methods, nor will it be interfered by electric and magnetic fields.

5. The operation is simple, the use of computer numerical control technology can realize automatic processing, can be used for high-speed and high-efficiency processing of parts and components on the production line, and can be used as a part of the flexible processing system.

6. The precision workbench can be used for fine micro processing.

7. Use a microscope or camera system to observe or monitor the condition of the processed surface.

8. It can pass through light-transmitting materials (such as quartz, glass) to process its internal parts.

9. The prism and mirror system can be used to focus the beam on the inner surface or inclined surface of the workpiece for processing.

10. Can mark bar codes, numbers, characters, patterns and other signs.

11. The line width of these signs can be as small as 12mm, and the line depth can be up to 10mm or less, so it can mark the zero surface of the "millimeter" size.

When the common metal materials are engraved, lines with a depth of several microns or more (the width can be several microns to tens of microns) are ablated from the surface to make the color and reflectivity of the lines different from the original ones, resulting in visual contrast, so that people can be sensitive to these lines (and the shape codes, numbers, patterns, trademarks, etc. formed by the lines). For glass, these ablated lines have a "dullening" effect. For plastics, due to the photochemical reaction and ablation, there are visual contrast and smoldering effects. If the surface of the material is coated with a special colored substance for marking, the colored substance will be fixed (a high temperature ablation with the material) on the line and make it colored.

Light Engraving VS Deep Engraving for Metal

Laser metal engraving is divided into two types: light engraving and deep engraving (relief engraving). Generally, the depth of light engraving is 5-25mm, the depth of deep engraving is generally deeper, and the specific depth depends on the different metals, the laser power and the time of engraving.

Light engraving is typically used for permanent marking on the surface of various tools and parts. Deep engraving is mainly used for engraving abrasive tools and seals.

In short, the engraving depth is related to factors such as the absorption of the laser by the engraved material, the power of the laser, and the action time of the laser on the engraved metal. Deep engraving usually requires a longer action time. Deep and light engravings can be carried out on the surface of various metal materials, such as signs, identification codes, company logos, and more complex images.
