SY N OPSI OPS I S

The Machine we designed and fabricated is used for grinding any shape of object like Circular, Rectangular, and Polygon. In our project the work abrasive 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

INTRODUCTION

Our project is 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





































NEED FOR ATTACHMENT Generally some components in engineering field require surface finish and accuracy.

For example a

cylindrical part requires finish outside the body; it requires cylindrical grinding machine. The above machinery cost will be more, and also unless we have lot of similar jobs, we equity keep these costly machines machines idle. To avoid avoid this heavy investment investment and





































LITERATURE SURVEY SLOW GRINDING:

Grinding is widely regarded as a necessary evil, an art rather than a science. The oldest machines in any shop are typically grinding machines because there isn't enough justification to invest in new ones. Until now, any increase in productivity on a grinding machine has been made in





















FAST VS SLOW GRINDING:

Lately the focus has been on high-speed grinding and machining. The theory is that a grinding wheel, which is





















difficult to justify in a production-oriented environment where today's profit margins are slim. Has anyone ever considered that maybe we are going in the wrong direction? Slow speed grinding has been discussed in the past, and some experimentation was done
