MLP is working on producing a “Conveyor Drive Shaft” for the food processing industry.
They begin with a 1-1/2 Square bar material, grade 303 SS, measuring 30” long.
They proceed to turning journals on each end, measuring .9995 -.001, using a 20” x 60” engine lathe with a tail stock for support. The last step will be to add a .25 keyway on the drive end journal.
Watch the chips flying off as it turned from square to round in this short video.
