Milling Flutes in Taper Reamer
There are times when a shop requires a reamer of special size that cannot be procured readily, and in such cases one can be turned up and the flutes cut in the manner shown above. The spiral head is set at the angle of taper and the foot-stock centre is adjusted to correspond with it. The reamer blank is then mounted on the centres and dogged to the spiral head spindle.
A stock cutter, known as a reamer fluting cutter, is used and the table is fed longitudinally.
The procedure is the same for milling a straight reamer, except that the spiral head and foot-stock are set at zero.
