DESIGN AND FABRICATION OF AUTOMATIC

MARBLE POLISHING MACHINE

Abstract:

Automatic Marble Polishing machine is a machine used for polishing of marbles and granites for

flooring applications in the construction industry, since it is found that a labour is to be deployed

for the polishing operation. In the construction company the marble is most preferred option, as

far as the flooring needs of new establishment are concerned. Marble polishing serves the

combination of various proven techniques to clean and restore the marble flooring efficiency.

For example Grout Washing, this is used as a post installation process for surface finishing of

floor. Grout Haze purifiers are commonly used for maintenance. Although, Marble is a non-

porous and that precisely means it is blemish poof .However with time marble also experiences

some loss in its shine and everyday wear and tear could result in open pores that always remain

filled with muck and dust. To restore marble flooring is used. The process of marble polishing

fundamentally makes use of marble sealer and various proven marble shine techniques. The

sealer is mainly used for sealing any pores, which may have been left open during the

installation, and the shining techniques, such as grout washing, are used to provide a new shine

and gloss to the flooring.

The set up includes Marble polishing disk which is mounted on the floor in turn is vertically

fastened to the motor, which rotates at constant speed, the sensors are mounted over the panel to

sense the obstruction or the existence of walls which senses and conveys the signal to control

unit which is equipped with microcontroller, which is programmed to the moment of the

machine in a grid pattern. A separate gear is used for the movement of the set up, which is

controlled by micro controller for speed and direction.

Working Principle:

Sensors are used to apply four main functions: obstacle avoidance, wall follower, random

wanderer, and blob detection. With these four basic functions, the robots can perform other more

complicated tasks.as it detects the obstacle it will take a curve depending upon the functionality

as we will program microcontroller. The marble polishing motor will clean the marble with the

water that will pour with the small tank which is located in the module, The marble polishing

motor will be of 1440 rpm motor with the traverse speed will be some around 1.5-2mt/mnt, For

the obstacle avoidance the sensor will sense the obstacle and the sensor will sends the signal to

the microcontroller, the microcontroller controls the machine driving motors using the H-bridge

system(L293d) which is used to run the motor in clock and anti-clock direction, the direction of

the motor will be depending upon the signal that will receive the from the sensor to the

microcontroller, the microcontroller what we are using is the AT89s52 which is manufactured by

Atmel company, the microcontroller will be a 40pin Ic It has 4 ports Each port has its own

functioning. The driving motor of the machine will be a 12v DC gear motor which is consisting

the gear inside the motor which will help the motor to drive in the smooth condition with its

2way rotation technique. Both AC and DC can be used as the power source for the polishing

machine, which will require the Power Supply Design for the machine, as it will take a Speed

depends on the load of the machine and the machine will polish the required space available.

Present Scope:

Floor polishing. Floor cleaning.

Future Scope:

Glass cleaning for high rise buildings. Wall painting.
