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, 912" in diameter. The table is fed from left to right on account of projections at end of casting.
