Broaching is a method of removing metal by pushing or pulling a cutting tool called a broach which cuts in a fixed path.. In broaching machine, the tool of the machine is pulled or pushed through the surfaces to be finished.With the help of broaching, finishing is done on flat or contoured and either internal or external surfaces. Broaching is limited to the removal of about 6mm of stock or less.
