Laser cutting is a process that has been around for longer than most people realise; the first commercial cutting machine appeared in 1965. In recent years there have been many companies making and using laser cutters; they range in power from several kilowatt down to around 3 watt . The latter is only capable of cutting paper and thin card whereas the largest machines easily slice through 20 mm thick steel.
The beam is generated in a glass or metal tube containing a mix of gasses mainly carbon dioxide Co². This is excited by a very large voltage of around 35 kilovolts (over 150 times more volts than you get from a domestic socket). This excites the gas in the tube and photons are generated.
Now we have a beam of laser light that we can use to cut. This beam is reflected to the work by mirrors and focused into a cutting beam with a lens. The work simply lays on the cutting bed and the laser head moves over it controlled by computer driven motors.
Each part that is cut is exactly the same the process is highly repeatable. This means once we have designed something for you we can just reload the file and effectively make another exactly the same as the first.
