Broaching (metalworking)
The concept of broaching can be traced back to the early 1850s, with the first applications used for cutting keyways in pulleys and gears.
write a detail note to the broaching machines Broaching machines are relatively simple as they only have to move the broach in a linear motion at a predetermined speed and provide a means for handling the broach automatically. what is this machine used for? To remove material. what are its various types? "linear" and "rotary". how does it work? In linear broaching, the broach is run linearly against a surface of the workpiece to effect the cut. In rotary broaching, the broach is rotated and pressed into the workpiece to cut an axisymmetric shape. by whom was this machine developed? UNANSWERABLE when was it first used? early 1850

Broaching (metalworking) [SEP] History
The concept of broaching can be traced back to the early 1850s, with the first applications used for cutting keyways in pulleys and gears. After World War I, broaching was used to rifle gun barrels. In the 1920s and 30s the tolerances were tightened and the cost reduced thanks to advances in form grinding and broaching machines.
