The tax identification number is This is adjusted by the user with a large vertical movement crank. Milling machines were originally developed to speed up hand-filing. The s - s brought the creation of a few popular designs, many of which were geared towards production. From there, production took off as WWI approached.

Milling technology developed rapidly for the next few decades, and the introduction of high-accuracy machines like the Jig Bore set the standard for milling accuracy. Now machinists could quickly and accurately locate holes with great precision, making mills commonplace for prototyping and producing wartime equipment. This rapid development continued into the the post-war period, during which a few key technologies developed, including anti-backlash nuts, which led to even greater accuracy.

In Rudolph Bannow conceived of the Bridgeport milling machine, which is still in production today. It was lighter, cheaper, and easier to use than many of the milling machines on the market at the time, and became an instant success. Its success inspired others to copy the design, which lead to numerous clones. Initially, NC machining was used only in aerospace applications, where recreating complex airfoil and wing profiles proved difficult to do reliably.

It caught on slowly elsewhere, but accelerated into full CNC Computer Numerical Control in the 60s and 70s when data storage and input methods improved. Although three-axis milling machines are most common, certain applications may demand additional axes.

Not all three-axis machines are capable of the same thing, either. It was after this century and a half when the first Correa milling machines were manufactured with a staff of just twelve workers. The first model was Correa BC and after that the F2 range appeared; a kind of machines that incorporate electromagnetic clutches enabling them to increase their roughing capacity, while maintaining the same level of precision. Up to , the Correa A milling machine was a major innovation, since it incorporated a numerical control.

Moreover, thanks to its larger size, it was able to machine larger parts. The first milling machine in history maintained all its features and initial functions during a century and a half. Whitney, best known for his invention of the cotton gin, is regarded by many as the first to design a reliable milling machine. He produced it hoping it would help with the mass-production of gun parts.

It is this goal that gave us interchangeable gun parts. Prior to Whitney, all guns were hand-crafted. In , however, the federal government contracted him to produce a larger order of muskets. By building a semi-automated machine tool factory, he was able to get around this issue.

In turn, we have his innovation to thank for customizable weapons. American engineer Joseph R. Brown was also a major player in the rise of milling machines. At the Paris Exhibition of , he brought along his universal milling machine to showcase. It was incredibly versatile, first being made to build spiral flutes for twist drills and later gaining a formed cutter. Since then, the only industrial machine tool more popular is the lathe.
