What Is a Milling Machine?
The milling machine is a tool that cuts a variety of materials. This type of machine can hold one or more cutters and is very accurate. Its metal removal rate is higher than a lathe, shaper, or planner machine. Its accuracy and surface finish are also superior. Its table is usually made of cast grey iron with a hollow base, which provides the machine with a convenient reservoir for cutting fluid. A milling machine is divided into two basic categories: knee-type and universal milling machines. The former is more compact and lightweight, while the latter has a rigid table and a knee-style mount. They differ in the design of the table mount and the type of milling tool they use. Some milling machines have a high-speed, variable-speed motor while others are fixed-speed mills. The milling machine was originally used by clockmakers as a way to cut wheels. It was later developed by Eli Whitney, who also developed the cotton gin. Then, it was used to mass-produce gun parts. T...
