Description
The Bridgeport Series 1 Mill is a vertical mill used to mill various materials into desired shapes and sizes. It can also be used to perform special functions such as drilling, chamfering, reaming, fly cutting, and many more. Some examples of items made from mills are piston bore holes, valve plates, gears, and even your own tools. This is done by using a rotary cutter to remove material by advancing a cutter into a work piece in varying direction along three axes. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes for machining custom parts to precise tolerances. The video below shows a part being machined by a CNC mill which is a computer driven mill, but still demonstrates the milling process.

Terminology
- Spindle - The rotating shaft, driven by the motor, that holds the cutting tools.
- Quill - The part of the vertical milling machine that raises and lowers cutting tools held in the spindle.
- Endmill - A common machining tool having cutting teeth on the end of a cylindrical shank and usually spiral blades on the lateral surface. Because of this geometry it can cut in any direction.
- Facing - The process of cutting a flat surface perpendicular to the axes of the milling cutter on the initial piece of raw stock.
