For every beryllium machining operation, the shop programs and sets up a sample workpiece, machines it in aluminum, then sends it for inspection. When the sample part passes inspection, one test part is machined from beryllium. If that part meets specifications, the shop machines the rest of the lot in beryllium.
What is a milling operation? Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done in varying directions on one or several axes, cutter head speed, and pressure. The original class of machine tools for milling was the milling machine (often called a mill).

Unlike aluminum, it resists corrosion by salt water, etc. Its rate of expansion with heat is the same as that of cast iron. It alloys easily with aluminum. An alloy of beryllium 70% and aluminum 30%, is one-fifth lighter than aluminum, and resists corrosion much better. In tensile strength it greatly exceeds duralumin.
