Milling Pair of Grinding Machine Tables on a No. 5 B Heavy Plain Grinding Machine

Where the size of machine and character of work permit, it is very advantageous to mill more than one piece at a time. This operation illustrates how two plain grinding machine tables are milled simultaneously.

The two tables are held in a fixture, the essential features of which are plainly apparent in the cut. There are two sets of cutters made up of plain milling cutters and interlocking mills. Another feature of this operation is the placing of the arbor yoke between the two sets of cutters.
