Shaft milling is a high-speed metalworking process that uses a rotating blade to cut or shape raw materials. It can be used for various applications and requires little finishing. The machine can run at any angle and is commonly used in the automotive and aeronautical industries. The process is suitable for most materials with a hardness of C25 on the Rockwell scale, including brass, aluminum, cast iron, and steel.
Shaft milling is a high-speed machining and metalworking process that uses a rotating multi-tooth cutting blade to cut or shape the surface of a raw material. As a shaft mill blade turns, it cuts small pieces of raw material and ejects debris from the cut, leaving a smooth edge that requires very little finishing. The process differs from drilling in that the shaft milling cutter blades rotate on an axis of rotation parallel to the cutting surface.
This cutting process is used for a variety of applications in the metalworking and manufacturing industries. It has the ability to quickly remove debris leaving a clean cut that requires little, if any, finishing, so the shaft milling machine has become standard equipment in the industry. With the different types of arbor milling blades including carbide, tool steel, diamond and ceramic, the types of materials that can be milled and the resulting surface finishes are very varied. As a highly versatile tool that can be easily adapted to a number of uses, the shaft milling machine finds use in the automotive, aeronautical and other manufacturing sectors.
The cutting blade of the shaft milling machine is positioned at the end of a rotary axis and the raw material is pushed into the rotation of the blade. If the raw material is pushed in the same direction as the rotation of the blade, it will be dragged by the blade, and this is called up milling. If the raw material is pushed into the blade against rotation, this is called conventional milling.
The shaft milling machine can be set up to run at any angle, but the most common configuration in industrial use is the horizontal milling machine. With the various configuration options and available arbor milling blades, the arbor milling process can be used for a variety of cutting purposes, including flat cuts, shaping and forming contours on the surface of the raw material. The shaft mill is designed to shape the surface of stock materials, so the process is often used to create joints and channels in metalworking projects.
The shaft milling process is appropriate for most materials with a hardness of C25 on the Rockwell hardness scale. Common industrial metals used with the shaft milling process are brass, aluminum, cast iron, and steel. With the use of specialized shaft milling equipment, such as carbide or diamond tipped blades, even harder materials can be milled using this process.
