Abrasive Belt Grinder

 The Machine we designed and fabricated is used for grinding any shape of the object like Circular, Rectangular, and Polygon.  In our project the work, abrasive belt is used to grinding the material. The abrasive belt is rotated by the single phase induction motor. Hence our project, namely abrasive belt grinder is a Special type of Machine.  According to the type of material to be grind, the grinding tool can be changed.
This project gives details of grinding various shapes and sizes of components.  This machine can be widely applied in almost all types of industries. By varying the pulley sizes I can get a high end speed of over 10,000 RPM if needed. The only change I would make is to have a totally enclosed motor to keep out the grit.

Our project is the design and fabrication of Multi Use abrasive belt Grinder.  It is used to grind the machining surfaces to super Finish and accuracy.     It can be used as an external Grinder by fixing the belt grinder attachment on the conveyor roller. The principle parts of this attachment are main body, motor with pulley, bearings, rope pulley and conveyor abrasive belt etc.

The abrasive belt is used to grind the material. This abrasive belt is rotated by the single phase induction motor. In our project consist of the end bearings with bearing cap, roller wheel, shaft, single phase induction motor and abrasive belt. This whole arrangement is fixed on the frame structure where the component rests.
The roller wheel is mounted on the two end bearings with bearing cap by suitable arrangement. There are two roller wheel is used in our project to rotate the abrasive belt. One side of the roller wheel shaft, one v-pulley is coupled by the suitable arrangement. The single phase induction motor with V-pulley arrangement is used to rotate the abrasive belt through the belt drive mechanism.

The machine is compact and rigid in size.
Maintenance is less.
It can be used in any place of small grinding application
By varying the pulley diameter the speed of the abrasive belt to be changed.

The abrasive belt should be changeable one for different material. This process takes more time.

Grinding outside the job in any size of the body can be done.
As the feed is given automatic, 0.8 micron finish may be achieved.
By changing the grades of abrasive belt grinding it can be used to grind the carbon steel, Alloy steel and stainless steel etc.
