uMeta

μMeta is a laser marking workstation commonly used for permanently marking parts that are manufactured from most metals and some plastics with logos, general text, serial numbers and many formats of coding. It has 305 x 305mm T-slot work area with a fully automatic, pneumatically operated access panel that provides the operator with an immediately obvious indication when the job has finished, (the door goes up), as well as 180° access to the work area. μMeta can be configured with a variety of lens options and with 450mm of Z-axis travel distance controllable by software. It can also be fitted with an optional rotary axis chuck for cylindrical objects. μMeta is designed to be space and energy saving and is manufactured using recyclable materials

What is Laser Fume?

Lasers are now an essential tool in industry for cutting, marking and engraving a vast range of materials. In virtually all these operations some form of fume is given off as the laser thermally decomposes the substrate to a greater or lesser degree. This fume is a mixture of particulate and gaseous matter.

Fume from materials such as metals and glass is mainly particulate, the majority of which is less than 1µ (micron) in diameter. Organic materials, particularly plastics, produce much more complex fumes which require a greater level of extraction. Most of the particles are spherical and roughly 90% by weight are less than 1µ in diameter. These particles fall within the respirable range and need to be removed from the working environment to prevent bronchial or lung damage. These gaseous organic compounds produced are known as Volatile Organic Compounds, VOC's.

CSI have teamed up with BOFA International to offer a range of self contained fume extraction systems to suit your chosen laser and create a safe working environment.

FAQ

 

What is the Laser Source of the uMeta Laser?

The source is a fibre laser: a fibre optic cable that has been doped with ytterbium, a rare earth element.

 

Is it the same as a YAG (yttrium aluminium garnate) laser?

The fibre laser produces the same wavelength of light and the same marks. YAG lasers typically require cooling and more maintenance.

 

What is the wavelength of the uMeta Laser?

1060-1079nm

 

Is the wavelength of light dangerous?

Yes, especially to the operator's eyes. Additionally, the wavelength will pass through common Lexan or glass materials, which is why the viewing window has been impregnated with an organic compound that absorbs the fibre energy. Do not run the laser with the safety door open.

 

What is the power consumption of the uMeta Laser?

230VAC 50Hz  <1 Amp 180 watts

 

What is the laser beam spot size?

The beam spot size dependant on the size of the lens:

70mm Lens =?

110mm Lens =?

170mm Lens =?

 

How deep can it engrave into metal?

All metals can be engraved into with some depth; however, some metals are more amenable to depth engraving. Softer aluminium material will engrave with depth with only a few passes. The best way to test your material is with our Applications Lab.

 

Can the uMeta cut?

No. It is a dedicated engraving/marking system for metals and industrial plastics

 

What is the maximum table weight for the uMeta      

30kg

 

What is the maximum diameter that will fit on the Rotary?

200mm. 2kg in weight

 

Do I need to use a dedicated graphic software package?

The uMeta comes with easy-to-use LotusMark software which gives total control on speed , power and engraving  direction.

 

What sort of images can I engrave or cut?

You can engrave text, logos, barcodes, scanned photos, , bitmaps, and AutoCAD files. Essentially, if you can print it, you can engrave it. Keep in mind the higher the quality of the graphic you're working with, the better your engraving results

 

Is it safe to use?

Yes, the laser is completely safe to operate. It is a Class 2 laser - which means that the laser is secured with interlock devices so it will not run with the cover up. The system has an emergency stop and isolation key switch and a safe viewing window.  No special safety gear is required to run the laser.

 

What are the computer requirements?

The LotusMark software is Windows based and connected to the laser via USB to a max length 2.5m.

Your standard off the shelf laptop is adequate.

 

Why do I need fume extraction?

When laser marking materials they will give off some form of fume as the laser thermally decomposes the substrate to a greater or lesser degree. This fume is a mixture of particulate and gaseous matter.

Fume from materials such as metals and glass is mainly particulate, the majority of which is less than 1µ (micron) in diameter. Organic materials, particularly plastics, produce much more complex fumes which require a greater level of extraction. Most of the particles are spherical and roughly 90% by weight are less than 1µ in diameter. These particles fall within the respirable range and need to be removed from the working environment to prevent bronchial or lung damage. These gaseous organic compounds produced are known as Volatile Organic Compounds, VOC's.

The uMeta laser must have some form of fume extraction fitted. We recommend a suitable filter based self-contained fume extraction system to create a safe working environment.

 

What is the cost of the uMeta laser system?

The cost of the uMeta laser systems is determined by the power of the laser source and the accessories required They can be bought outright or leased through one of our finance partners. For more information on how to own your own laser please contact our sales team.
