Production. Milling machines and machine castings. A large tracer-controlled multiple spindle vertical hydraulic milling machine being tried out on the runoff line of a large machine tool plant, for its eventual job of helping to make master connecting rods for radial aircraft engines. Four of the partially completed rods are mounted on the fixtures in the foreground. When in operation, the machine will have fixtures for eight such rods, so that while the completely automatic tracing finger guides the four cutters (extreme background) around one set of four rods, the operator can be unloading and reloading the other four fixtures with new parts to be milled. This machine will probably be the fourth or fifth of a series of perhaps a dozen different sizes and types of machine tools which will each have to perform their operations before these parts become finished connecting rods

Production. Milling machines and machine castings. A view of the manufacturing area of a large machine tool plant. The finished parts and sub-assemblies stacked in the foreground give some idea of the complexity of machine tools. One average milling machine has about 2000 separate metal parts, most of which require much more skill and care than those of the automobile
