132 Cutting Slots in Circular Milling Attachment Table on a No. 4 B Heavy Plain Milling Machine

Three parallel slots are cut in the top of this table by spacing three cutters on the arbor by means of collars.

Considerable power is required for the operation, as the slots are cut from solid stock to the depth of $7⁄8$ of an inch, and $9⁄16$ of an inch wide.

Specially shaped straps are necessary to fasten the work to the table, in order to make use of cutters of small diameter.

The cutters employed are regular stocking cutters 6 inches in diameter, and are rigidly supported on the arbor.
