what is a ball end mill
May 14, 2024
A ball end mill is a type of milling cutter commonly used in machining operations. Here's what it is and how it differs from other types of end mills:
Shape: A ball end mill has a rounded tip, resembling a ball. The cutting edge is not flat but instead has a curved profile, which allows it to create contoured surfaces or rounded features in the workpiece.
Design: The cutting edge of a ball end mill is generally perpendicular to the axis of the tool, which means it can cut horizontally as well as vertically.
Applications: Ball end mills are commonly used in machining operations where smooth surface finishes or rounded features are desired. They are particularly useful for 3D contouring, sculpting, and finishing operations.
Materials: Ball end mills are typically made of high-speed steel (HSS), cobalt steel, or carbide, which allows them to cut through a wide range of materials, including metals, plastics, and composites.
Flutes: Ball end mills can have varying numbers of flutes, typically ranging from 2 to 4 or more. The number of flutes affects the chip evacuation and surface finish of the machined part.
In summary, a ball end mill is a versatile tool used in machining operations to create contoured surfaces, rounded features, and smooth finishes in a variety of materials.
