Using Tipco Engineering Mill Machines to remove material from a workpiece is known as the milling process. Milling machines remove material by rotating their cutting blades as they press down on the body of the workpiece. To guarantee that the workpiece cannot rotate or be rotated in any other way, it is fixed in place. However, when the milling machine operates, pressure will be applied to a cutting tool that rotates and presses up against a stationary workpiece. The cutting tool goes over the workpiece, eventually removing material to leave behind a smaller workpiece.
