Description
Broaching is one of the most precise and productive process in the metal working area.The price per peice of broaching is very low because of its high production and low cycle times. Many times dispensing milling operations and it requires no skilled labour. The quality is often best than other combined cutting process. Many operations can be replaced by broaching, earning lots of time and and requiring less tools. One of the major advantages of using this operation in various industries is its ability to give better surface finish and good accuracy with mass production rate. Commonly machined surfaces include circular and non-circular holes, splines, keyways, and flat surfaces. Typical workpieces include small to medium-sized castings, forgings, screw machine parts, and stampings. Broaching is usually favoured over other processes when used for high-quantity production runs. The shape of the broach bars teeth are similar to a saw, except the height of the teeth increases over the length of the tool. Moreover, the broach contains three distinct sections: one for roughing, another for semi-finishing, and the final one for finishing.
