Production. Milling machines and machine castings. Many holes have to be bored in the innards of a machine tool's main casting to accomodate gears, shafts, tubings and mountings which eventually comprise its interior. This workman uses every one of the drills and reamers shown here on each milling machine bed casting that he receives

Production. Milling machines and machine castings. A close-up of a milling operation on a large bed. Note the multiple-touch cutter, larger than an elephant's foot, turning at the left. Facing it on the other side of the casting is another cutter of the same size, milling the other side. Special fixtures and cutters are used for different shaped castings machined on this special milling machine, produced in a large Midwest machine tool plant

Production. Milling machines and machine castings. It's all a matter of relative angles and turning speeds. Properly set, this gear-cutting machine tool will produce any kind of beveled, spur, hypoid or other kind of gear. The small hypoid bevel gear shown partially cut in the center of the picture will soon become part of another machine tool after it has been heat-treated, ground, lapped and thoroughly tested and checked

Production. Milling machines and machine castings. Welders, too, are busy men in machine tool plants. Most of the oil and coolant tanks, guards and hundreds of other parts are made in the sheet metal and welding shop where men work with steel as cabinetmakers work with wood. Some machine tools, longer than a freight car, have beds so large that they can't be cast, and are therefore welded up from steel plates as much as two to three inches thick

Production. Milling machines and machine castings. Another scene in the runoff line where three-inch shells are being run through a centerless grinding machine which grinds them to exactly correct roundness, size, straightness and smoothness. Designed to be blown to bits as soon as possible, each shell must nevertheless be made and finished as carefully as if it were to last as long as the piston of an automobile engine

Production. Milling machines and machine castings. After losing their cores and being sand-blasted, castings go to the cleaning floor. This workman was using a pneumatic chipping hammer which with rapid-fire, chisel-like strokes trims rough edges and cuts off the uneven, jagged strips where the two halves of the mold join. Location: a large Midwest machine tool plant

Production. Milling machines and machine castings. The electrician is indispensable in the manufacture of modern machine tools. This one is crouched in the base of a powerful giant milling machine which may be used to help make aircraft engine or propeller parts day in and day out. Machines of this type are fitted with motors and controls, ready to run when they arrive at the customer's plant
