What Are The Different Ways of Cutting

Metal for Fabrication?

Cutting is one of the most important processes for Metal

Fabrication. In most of the cases, it’s the foremost step as well.

For the metal to be altered into different shapes and sizes, it

needs to be cut with required precision and expertise. Different

metals differ in quality and properties and therefore different

cutting methods are required to cut them. In this article we will

discuss about the different ways of cutting metal for fabrication.

Manual Cutting​​ – ​​For small scale jobs, manual cutting may be

preferred to get the desired shape out of a metal sheet. Mostly,

only thin and flexible metals like thinner gauge aluminum,

copper, brass, etc. are preferred for this kind of cutting. Hand

tools are employed to do the work manually. This method is not

ideal for cutting smaller pieces as it might just break the metal

instead of cutting them into precise sizes.

Grinding​​ – ​​Grinding is preferred for doing high quality jobs

when the surface of the metal requires to be smooth and

polished. In this method, a grinding machine is used, which

consists of an abrasive wheel. Friction is used to wear down the

surface of the metal to get the desired finishing of the product.

Laser cutting​​ – ​​It’s the latest technology involved in metal

cutting and is increasingly being used for the process. High

powered and concentrated beams facilitate the cutting of the

metal with the help of a focus lens and other ​laser parts​. It is an

automated process where the design is programmed into the

computer which controls the laser. Laser cutting is a very

consistent and steady process which is used to cut metals of

precise measurements. It offers unmatched flexibility by

accurately extracting the most complex of designs out of metal

sheets.

Welding or Burning​​ – As the name suggests, heat is the

medium to cut the metal. Intense hot flames are used to cut the

metal by burning and melting it. Plasma cutters are the latest

technology to support this method of metal cutting as it provides

high degree of accuracy because of much higher temperature. In

a plasma torch, oxygen or other inert gases are pumped through

its nozzle at a tremendous speed along with an electrical arc. It’s

the most accurate method after laser cutting.

Water Jet​​ – ​​This method is mostly favored for metals that

don’t go well with heat. Under this method, a highly concentrated

jet of water cuts through the metal to get the desired shape. The

water is often mixed with abrasive compounds to ease the

process of cutting metals.

Punch​​ – ​​Another much employed method of cutting metals,

punch involves the use of extreme pressure to force sharp blades

into the metal and cut them. Though it might sound similar to

manual cutting of metals, machines are capable of putting much

more force than humans and therefore, are able to cut heavier

metals at a rapid speed. It’s one of the most productive methods

of cutting metals.
