End Mill
An end mill is a versatile cutting tool commonly used in CNC milling machines for machining metals, plastics, and other materials. Unlike traditional turning tools, the cutting edges of an end mill are located at the tip of the tool, allowing it to cut both horizontally and vertically. There are various types of end mills, including flat, ball nose, radius, and wave designs, each suited for specific applications. For example, flat end mills are ideal for general-purpose milling, while ball nose end mills are used for 3D contouring and precision surface machining. Materials commonly used for end mills include high-speed steel (HSS) and carbide, with carbide offering superior hardness and wear resistance for high-speed machining. The number of flutes on an end mill (2, 3, 4, or 6) also affects performance, with more flutes providing better stability and higher feed rates. Choosing the right end mill depends on factors such as the material being cut, cutting conditions, and the desired level of precision. Regular maintenance, including checking for wear and cleaning, is essential for maintaining tool performance and extending tool life.
