Surfacing Face of a Grinding Machine Apron on a No. 3 Vertical Spindle Milling Machine
A vertical spindle milling machine is peculiarly adapted to work having a long projecting hub, or where it is necessary to surface off some part inside, such as in gear cases. The operation above is typical of such work, and shows a casting that must be milled all around the outside edge.
The casting is clamped in a special fixture, and a shell end mill is employed. The outline of the edge is followed by using the horizontal and transverse table feeds alternately for the different sides.
