Laser cutting solved previous issues faced with manual cutting and gave the ability to work faster, more precisely and for longer periods of time whilst still delivering high-quality products. Common industries now making use of laser cutting services include automotive, aerospace, electronics, semiconductors and medical.Get more news about laser cutting line,you can vist our website!

What is CNC laser cutting?
Laser cutting works with the use of CAD files, it is a precise method of cutting a design from a given material. It involves firing a laser which then cuts the material using melting, burning or vaporising processes. Laser cutting has many benefits over conventional cutting methods. Due to this, Alpha Manufacturing delivers high precision sheet metal laser cutting services using the latest technologies, including CO2 and fibre laser machines.
Precision
Laser cutting technologies are highly focusable to about 25 microns, which is about 1/4 of the width of a strand of human hair, it has a positioning accuracy of 10 micrometres and repeatability of 5 micrometres. This makes it feasible to remove the minimum amount of material to make the cut, aiding precision and accuracy.

In laser cutting, the optic is fed compressed air via a jet system with a variety of nozzle widths available. This affects the cutting process by constantly expelling the evaporated material and residues making for a better cutting quality and keeping the focus optic free of dust. In conventional processes, the heat generated while cutting can cause damage to the material such as warping. Another advantage of high power laser cutting is that the area subjected to heat is very small, which reduces the risk of damage to the material. It also helps avoid costly repair and maintenance schedules for moving parts that contact the work surface.

A laser cutting machine gives highly accurate cuts that leave a clean and smooth finish. Traditional cutting services can only offer cutting lines as thin as the smallest diameter cutter, whereas the laser beam can be programmed to hundredths of a millimetre.

CNC laser cutting tolerances
CO2 lasers use a gas mixture and have an exceptionally high voltage, giving a powerful solution to sheet metal fabrication. Laser cutters offer minimal thermal input, with fine control over work area temperature. This is important since small parts heat up quickly and might otherwise overheat and deform.

Alpha Manufacturing uses the latest in laser technology, including fibre laser cutters. Fibre laser light is created by banks of diodes. The light is channelled and amplified through fibre optic cable similar to that used for data transfer. These can cut mild steel up to 25mm, stainless steel up to 20mm and aluminium up to 12mm.
