Rh Face Milling, Using Heavy Vertical Spindle Attachment on a No. 4 B Heavy Plain Milling Machine

It will be seen from the above cut that in shops where the volume of work does not warrant installing a vertical spindle milling machine, the operation that would generally be done on that machine can be done on a horizontal spindle machine equipped with a vertical spindle attachment. The illustration shows a very heavy style of attachment.

The operation is that of face milling a surface on a cast iron piece which is held in a special jig upon the table.

The cutter is of the inserted tooth style, $9 1⁄2$" in diameter. The table is fed from left to right on account of projections at end of casting.
