CNC Milling is a subtractive manufacturing process that removes material from a part. Stock material usually in the form of a billet is secured to a vise or fixture mounted to the machine. A high rpm spindle with cutting tools cuts away material until the finished parts dimensions are met.
CNC Manufacturing offers lower initial investment vs. molds used in forging or casting.
Providing lower lead times vs casting.
CNC mills can also be used to finish features on castings or forged parts.
CNC Milling is a good choice for low QTY. prototype manufacturing.
