Rh Surfacing Bottom of Screw Machine Bed on a No. 5 B Heavy Plain Milling Machine

This illustration shows the possibilities of the milling machine for doing work that might be termed in many shops as suitable for the planer only.

The extreme weight, large size and powerful leverage due to the large overhang of the piece, are all factors that serve to make this an unusual milling job that requires a rigid machine. The work and fixture together weigh over 1000 pounds, and the piece as it is fastened to the table is 25" high, and extends 35" out from the cutter.

Another unusual point is the size of the inserted tooth face milling cutter, which is 26" in diameter.
