CNC Laser Cutters For Quality Engraving

Laser cutting combines smooth, clean edges, fast speed, and extreme accuracy with the ability to repeat the cut over and over. A superior alternative to other methods of cutting technology, laser cutting has been proven to be the most cost-effective and preferred cutting method for use in many types of applications. Laser cutting requires minimal time to set up and little tooling, making it desirable for artwork and other projects. A large work table measuring 50″ X 100″ will enable the cutting of everything from small single application type projects, to materials up to full sheet size.

* How Does Laser Cutting Work?

Laser cutting involves a thermal cutting method, however, the area affected by the heat is small and very easy to manage and minimize while cutting, due to an extremely focused laser beam. Very tiny amounts of material are removed at a time to allow for close and intricate cuts to be made. Laser cutting allows the user to control several variables involved in the cutting process, which enables this method to be used on a large variety of materials, unlike many other cutting methods. The laser involved is capable of etching designs and images, cutting profiles, and even doing three dimensional photographs.

To produce shapes with sheet metal using laser cutting, as intense laser beam is used. With CNC laser cutting, a high density light beam. When this light beam energy is sharply focused through a very tiny hole in a nozzle, when it comes into contact with surface of the sheet metal, that piece then becomes vaporized.
No physical tooling is needed with this process, making CNC laser cutting an inexpensive option for short runs and prototypes. Parts that are cut using the laser typically will remain flat, with minimal heat distortion, with generally less than 10% of the total thickness of the material being cut. Another advantage to using CNC laser cutting is that the process creates a minimal number of burrs on the material.

* What Can CNC Laser Cutting Produce?
– Two dimensional cutouts, including shaped cutouts
– Enclosures
– Cams
– Brackets
– Mechanisms
– Holders
– Sculptures

* What Types Of Materials Can A CNC Laser Cutter Work On ?
– Stainless Steel
– Spring steel
– Plain steel
– Acrylic , with results yielding a desirable, almost polished looking edge
– Aluminum, but only using a more expensive laser that is more powerful
– Cardboard
– ABS plastic
– Carbon composite
– Corian
– Ceramic
– Foam
– Fiberglass
– Glass
– Kevlar
– Delrin
– Lexan
– Marble
– Rubber
– Leather
– Silicon
– Titanium
– Vinyl
– Slate
– Wood

**Materials such as plastics should be used with caution when laser cutting due to potentially harmful or toxic fumes. Copper alloys also present a problem when attempting to laser cut, because they can absorb heat and reflect the light from the laser.

* Pointers For Use In Projects

When using a CNC laser cutter, you should take your design into consideration. Some things to think about include:

– Works best when there are minimal holes and cutouts in the design
– Rounded corners are preferable choices when using the laser cutter
– Milling or punching may produce smoother results than laser cutting
– On thinner materials, will produce better quality edges
– Although edge burrs are minimal, consider smoothing the burrs for a better edge
– Warping may occur on pieces in which a lot of material has been taken away, especially when using flimsy materials
– Inside corners may be sharp and be slightly rounded

* Application Of The CNC Laser Cutter

The CNC laser cutter can be used for such tasks as light metal machining, leather cutting, fabric cutting, wood machining, decorative raster imaging on wood/ metal/ plastic, polished edge acrylic fabrication, and plastic parts fabrication .Laser cutting can be used in vector cutting, sheet metal fabrication, displays, control panels, polished edge acrylic, raster engraving, name plates, sign making, and much more.

*Various Options In CNC Lasers

A full range of table sizes are available, including 50 x 60 and 80 x 240 models, as well as a full range of lasers with wattages ranging from 100 watts to 600 watts. Fume extraction systems, capacitive height heads used in metal cutting, and vision systems for part orientation can also be purchased.  If you are researching laser companies its best to find one within your region or country.  Some decide to import from China but most of the time that causes a loss of time and money.  One such option is Bodor Laser out of China.  You can see Bodor reviews with some concerning feedback on this website.

*CNC Plasma Cutter, CNC Laser Cutter Kit, CNC Router, and CNC Laser Cutter For Sale

A CNC plasma cutter, CNC router, and CNC laser cutter kit are also available, but keep in mind that do it yourself projects can be time consuming and it is best to try the ready made product out first to see if you like it before building your own.

In order to find a CNC laser cutter for sale, wesbites such as SaleCNC.com carry various types of CNC products, including the CNC router and CNC plasma. For those who are handy and want to save a little money, the CNC laser cutting kit and instructions can also be found online. Used CNC machines are also available through online auctions such as mmi-auction.com and Ebay, and through sites that sell these machines in used condition, such as machinetools.com.
