A milling machine is a machine tool that uses a milling cutter to mill a workpiece. In addition to milling planes, grooves, gear teeth, threads, and spline shafts, the milling machine can also process more complex profiles. Usually, the milling cutter is mainly based on rotary motion, and the movement of the workpiece and the milling cutter is the feed motion. It is widely used in machinery manufacturing and repair departments. Whether you are using it for industrial manufacturing, equipment maintenance, or machine tool training, you can buy a suitable ordinary milling machine or CNC Milling machine at HOSTON.
