This interesting part was machined complete on the Tos Hulin “Live Tool” Vertical Lathe.
This is a dial plate for an indexing application mounted to a Camco gear box.
The part is 1″ thick aluminum, 57″ in diameter with 150 , .515″ wide radial slots and 600, .375″ diameter holes.
The flexibility of the “Live Tool” VTL is emphasized by the ease with which this part was machined. Turned and faced and then milled and drilled, all one machine, all one setup, all in one program.
