In this case the following procedure shall apply: 1) Prior to broaching, the cutter teeth will rest on the surface of the boss and the body of the tool will be free to move up and down. Note that the nut should be backed away from the body of the tool.

46、 2) The tool may be hand-held or used under a press. 3) Locate broaching tool pilot into the port. 4) Slowly apply a force to the mandrel while holding the body to allow the teeth to broach into the parent material counterbore. 5) Broaching is complete when the external shoulder of the mandrel conta

47、cts the internal shoulder in the body. 6) The installation force is then relieved and the tool is ready for removal. 7) To remove the tool from the boss, turn the nut in clockwise direction against the body and the man-drel will move the cutter up, away from the port counterbore.
