Broaching external gears on lathe - planetary gear

Broaching is one of the metal machining operations done by a multipoint cutting tool called broaching tool or broach. 

• The tool is made reciprocating linearly relative to the workpiece in the direction of tool axis 

• The relative movement, necessary fixtures for workpiece and the broach are provided by a machine tool called broaching machine 

• The broaching is a high productivity method as so many cutting edges work to machine the workpiece at a time •
