For creating workpieces comprising many
processes, the secondary machining method
is economical. To get the optimum results,
several operations are performed in a
predetermined order during the
machiningb process. Primary
manufacturing techniques like CNC or
injection moulding are followed by
secondary machining operations.

3.
● Drilling
This is a secondary machining procedure
known as computer numerical control (CNC),
which makes holes in a workpiece using a
round cutter. Although milling machines can
also be utilised, specially built drill pressing
machines are employed in this operation.

4.
● Milling
During milling, a multi-point rotary cutter
curves gear teeth, deep threads, or slots onto
the workpiece. Milling is a secondary
machining process that provides a fining coat
to the workpiece during the injection molding.

5.
● Turning
By turning the workpiece while a cutting tool
moves in a linear motion to produce the final
tube-shaped piece, the turning process can be
carried out either manually or automatically.
Higher productivity, consistency, and
efficiency are all made possible by using CNC.

6.
● Grinding
Injection moulding requires a tolerance surface
finish, which is where surface grinding
machining operations come into play. The
workpiece has a fine-tolerance finish thanks to
the powered abrasive paste, wheel, or belt used
in this process.

7.
● CNC Machining
Surface grinding machining operations are
necessary because an injection moulding
process requires a tolerance surface finish. It
gives the workpiece a fine-tolerance finish by
using a powered abrasive paste, wheel, or belt.

8.
● Tapping
Have you ever wondered how grooves are
created in bottles so that caps can fit properly?
Well, tapping is how this is done. It is the
procedure that aids in forming grooves on the
inside surface of the drilled hole by using a
conical thread or cylindrical cutting tool. A
CNC lathe may be readily programmed to do
tapping, which results in a very effective and
simple threading operation. This gives the
piece of art a final, definitive appearance that
will assist identify its purpose.
