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

This operation is essentially the same as the one just described, with the exception that the casting in the first instance was fastened in a special fixture, while in this case it is clamped directly to the table and the cutter is held on an arbor. The method of clamping needs little explanation, as it is very clearly shown in the illustration.

If it were not for the height of the hub at the right of the cutter, this job could easily be done without the attachment with plain milling cutters.

The cutter is $7 1⁄2$" in diameter and has inserted teeth.
