CNC machine
CNC
machine can be defined as the machine which is control by computer and the
operation is performed by feeding the program on it. CNC
machine operates on only two subjects which are CAD and CAM.
CAD stands for Computer-aided design. This subject helps you to learn about the
design of a machine and machines tools. CAM
stands for Computer-aided manufacturing. This subject is also similar to CAD
but it deals with manufacturing whereas CAD deals design.
Parts of CNC Machine:
A CNC
machine is consists of the following parts:
·
Bed
·
Headstock
·
Tailstock
·
Tailstock quill
·
Footswitch or pedal
·
Chuck
·
Control panel
·
Tool turret
Let’s go
into details.
Bed:
The bed
is kind of hardened parts of a machine because The tool turret travels over the
CNC lathe bed, kind of machining can’t affect them.
Headstock:
The
headstock is the main part of the machine, here the workpiece is fixed to
perform an operation and also Headstock of a CNC lathe machine has the main
motor which drives the main spindle.
Tailstock:
The
tailstock is for providing extra grip to the workpiece. When the operation like
knurling, threading has performed these parts used to hold the workpiece.
Tailstock quill:
This is
kind of setting the workpiece between the centers.
Footswitch or pedal:
Through
these pedals, CNC machinist’s open and close the chuck to grip the component,
the same way tailstock quill is taken to forward position or reversed.
Chuck:
Chuck is
mounted on the main spindle. Here we fixed the workpiece.
Control panel:
The
control panel is another main part of the CNC machine in which we use to set or
feed the program for the operation we perform on the workpiece. This is also
called the brain of a CNC machine.
Tool turret:
The tool
is mounted on the tool turret which is used for component machining. Tool
turrets vary in shapes and the number of tools that can be mounted on them.
These are the Parts of CNC machine, now I will talk about the CNC system.
