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
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.
