ABSTRACT
In our project explains about the pipe cutting by using
the mini cut off machine. It is focused only for small diameter
of pipe. At present electricity are used in a large amount for
cutting both small size and large size diameter of pipe. But in
our project we use only less amount of power. Vibrations are
controlled due to the limited weight imposed on the machine.
Since it is easily portable it shall be used by a plumber or an
electrician and it is even used in small cottage industries.

INTRODUCTION
One day our house was undergone with water leakage
maintenance. The plumber cuts the PVC pipes with hacksaw
blade, but while cutting the G.I pipes he measured the pipe and
took it to the lathe and then he cuts the pipe. At that time I
thought to overcome this problem. I decided to design a mini
cutoff machine. That resulted in our project.
This was designed mainly for Non-technicians such as
electrician and plumber.

COMPONENTS
•Electric Motor with Accelerator
•Cross Slider
•Vise
•Abrasive Saw
•Stopper
•Safety Guard

5.
ELECTRIC MOTOR WITH ACCELERATOR
This is the main component in this machine.
This motor rotates at the speed of 6500 per minute.
It requires low power.
The accelerator is used to control the motor
speed.

6.
CROSS SLIDER
The cross slider function is to provide cutting action to
the saw and the action of cutting saw will be perpendicular to
center line of machine.

7.
VISE
A vise is a mechanical apparatus used to secure
an object to allow work to be performed on it.

8.
ABRASIVE SAW
An abrasive saw, also known as a cut-off saw is a
power tool which is typically used to cut hard materials, such
as metals.

9.
STOPPER
It is used
when we need
number of products
with the same
length. It is made up
of an adjustable
screw.

10.
SAFETY GUARD
This is one of the
important measures in a
machine. There are two
safety guards in this
machine. One is for belt
safety and the other is for
spark protection.

11.
WORKING
Cut off machine operation is based on circular-saw
blade movement. Depending on the work piece type, various
kinds of blades with different rpm are selected. There is no feed
motion. The part is fixed firmly to the table to avoid uneven cut
in case of loosening. Preliminary process stages include precise
examination. First, the part is fixed and tested for security. Then
the circular-saw blade is inspected for security, integrity and
sharpness of blade. Next, the blade is switched on. The cutting
process starts only when the required rpm is reached. It is a
crucial point, since when the blade does not speed up enough it
can make an uneven cut or damage work piece edges. Every
type of cut requires a specific kind of blade. Thus, thin-walled
parts and work pieces require a fine-pitch blade. To cut a solid
part, it is reasonable to use a wide-pitch blade.

ADVANTAGES
 Portable
 Less maintenance
 Good efficient
 Easy to operate
 Multi purpose
 Easily available spares
 Long life abrasive saw

APPLICATIONS
Since the machine is portable, Non technicians like a
plumber and an electrician can take this machine to the
required site and cut the G.I and PVC pipes for the
required size.
A PVC bend manufacturer shall use this machine to
cut the PVC pipes for the required bend size, though we
can cut almost 650 pieces in an hour.
A motor key manufacturer uses this machine to
manufacture keys.
A carpenter uses this machine to cut wood reapers.
