Machining is
process in which a piece of raw material is cut into a desired shape and size
by a controlled material-removal process. This process have a common goal,
controlled material removal, this controlled material removal is also called a
subtractive manufacturing. Machining is a part of manufacture many products, it
can also used in various material like wood, plastic, ceramic and composites.
This process is done by a person who specializes in machining is called a
machinist. The space where machining is done is called machine shop.
Now the days
machining is done by computer numerical control (CNC), in which computer are
used to control operations of the mills, lathes, and other cutting tools. We
have three types of machining of process that is turning, drilling and milling.
(1) Turning operations- This is the
process that rotates the work piece as the primary method of moving metal against
the cutting tools.
(2) Drilling operations- This operation
is used to create round hole. It is done by a rotating tool that typically has
two or four helical cutting edges. The tool is work in a direction equal to its
edges.
(3) Boring- In this process we have bent
pointed tip is advanced into a roughly made hole in a spinning to enlarge the
hole and improve the accuracy. This process is done in final stage of manufacturing.
In Abrasive
machining we use a tool formed of tiny abrasive parts to remove material from a
work piece. It is a process like milling and turning because each particle cuts
into work piece removing a small piece of a material. We have two categories in
Machining operations.
(1)Roughing
cuts- Roughing cuts are used to remove a huge amount of material from the
starting work piece that is with a Large Material Removal Rate (MRR) to give a
desire shape to material.
(2)Finishing
cuts- This process is use to give finishing to the surface, and remove the unnecessary
roughness of the work piece.
There are
multiple machining companies in India. These top companies are YG1, Totem,
Indian tools, Miranda, HSS etc. They provide high quality machining in India.
You can buy these machining tools directly from the distributors or dealers.
Delhi is the wholesale market and these machining tools can be found in
Kashmere gate and Ajmeri gate. These machining are also available online on www.auzzaar.com. Auzzaar is one of the largest
online machining stores in India.
