Milling machines have better chip evacuation because of the nature of their configuration because gravity keeps the chips from falling. This helps improve the surface finish and prolongs the life of the tool.
Different types of milling cutters can be used to cut large amounts of material and leave poor surface smoothness (roughing) or to remove smaller amounts of material but leave good surface smoothness (finishing).
Milling is a machining method in which a milling cutter is used as a tool to process the surface of an object. Milling is a highly efficient machining method in which a rotating multi-blade tool is used to cut a workpiece.
A Bridgeport mill is a standard manual knee-type vertical milling machine. The reason that many people refer to a manual mill simply as a “Bridgeport” is that it’s one of the most famous brand names that’s found in most machine shops.
