automatic drilling and tapping machine

SYNOPSIS

          This project deals with Design and Fabrication of Automatic Tapping and Drilling Machine. In the present market the combined drilling cum tapping machine is not available.  For tapping we need either a manual process or a tapping attached in a drilling machine.  The former one consumes lot of time the later is quite costlier.

          For tapping operation we need to rotate the spindle in both clockwise and counter clockwise direction.  In our machine we have made bevel gear arrangement for auto reversal of the spindle. Thus based on the functional and economical aspects we have fabricated a unique machine.
