A face mill is a type of milling cutter used in machining to create flat surfaces on a workpiece. It features multiple cutting edges, allowing it to remove material efficiently. Face mills are typically mounted on a milling machine and can be used for various materials, including metals and plastics. The design of a face mill includes a large, flat surface with cutting inserts that can be replaced when worn. This tool is essential in manufacturing processes, especially in industries like automotive and aerospace, where precision and surface finish are critical.
