Laser cutting is one of the fastest processes that allow metal fabricators to create high-quality parts. The pieces cut by laser cutting fabrication machines require very little, if any, finishing work as the high-powered laser burns, melts or vaporizes away the excess material left in the cutting process.
Two most popular types of laser cutting machines widely in use today are CO2 laser cutting machines and Nd:YAG (neodymium-doped yttrium aluminum garnet) laser cutting machines. CO2 were one of the first gas lasers and are the most common variety of laser cutting machines. These machines have an excellent input output power ratio ranging its efficiency up to 20 percent. Nd:YAG laser machines use a crystal as a lasing medium and are extensively used in manufacturing industry for cutting and welding steel profiles and various alloys.
Benefits of Laser Cutting Machines
- Laser cutting machines cut metals with a very higher precision.
- Since the machine never comes in contact with the metal, there is no wear and tear on the equipment and there are less chances of the metal to become contaminated.
- Laser cutting is faster and more productive. Computer touch screens aid the laser equipment to plot out designs and the machine can cut multiple designs in one run by storing inventory on site.
- In laser machine cutting, the heat affected zone is kept small, thus reducing the possibility of warped material.
- Apart from being decently quite, laser profiling and cutting machines are safe too. Most of the laser machines are completely enclosed to prevent any kind of accident.
A few considerations
- Laser machines do not function well on highly reflective metals like aluminum and copper.
- Laser machines consume very high level of energy, making it more difficult for conventional metal fabricators to incorporate into its metal fabrication system.
- Holes created by laser cutting machines are slightly tapered with the hole entry being slightly larger in diameter than the exit.

Cutting tools for the planer operation are usually tipped with high-speed steel, cast alloy, or carbide inserts. High-speed steel or cast alloys are commonly used in heavy roughing cuts and carbides for secondary roughing and finishing.

you may have found the cheapest supplier but it's important to ensure they have the correct quality policies in place prior to you placing the work. Ask the supplier to provide you with some product samples or place them on a months trial so you can ascertain the quality of their product.dotlaser.co.uk
ReplyDeleteReally impressive post. I read it whole and going to share it with my social circules. I enjoyed your article and planning to rewrite it on my own blog. metal laser cutting machine
