ABRASIVE CUTTING MACHINE

ABRASIVE CUTTING MACHINE

INTRODUCTION:

Every time on the shop floor, it is required to cut metal piece from bar stock the existing methods to work out the same are:-

-parting on lathe
-sawing (either by band saw or power saw)
-Gas cutting etc.

In case of parting on lathe one can find that the length of job should not be more than distance between tail stalk and chuck, big diameter and odd shape object are difficult to part.

The sawing operations make use of to and fro-motion of H.S.S. band saw blade. The power saw machine is very bulky and it is not an easy task to cut soft and thin jobs as heavy clamping is required to resist high cutting force. The hand sawing is quite time consuming and its accuracy is very poor.

The gas cutting is comparative quicker, but it thermally distorts the material. Also there is always danger of oxidation.
Thus each of above processes has certain merits and demerits and it needs to have a special purpose machine, which will be more efficient, effective and economical.

The wheel rotating at 5000 rpm is progressed in the job. The operation is very fast and good finish and accuracy is obtained.
