At this stage the use of extra force is also likely to damage the casing. The ensuing friction then results in damage which prevents the stud from being easily removed. The threaded surfaces frequently bind against each other as a result of the application of unequal forces and the side-loading effects.
In either case damage to the casing can occur, especially when resorting to the use of hammers and manual wrenches without specialized sockets. Typical techniques involve using a double nut or by welding a nut onto the stud. Hole can be tapped before or after broaching.Conventional means of removing threaded studs can be time-consuming and costly. Caution: nut is for cutter removal only and is not a stop. If cutter sticks in counterbore, turn the nut in a clockwise direction to extract the cutter.
When the external shoulder of the mandrel contacts the internal shoulder of the body*, broaching is complete. Successful broaching of harder or tougher material may be accomplished, but tool cutter wear is to be expected.METHOD: The pilot is inserted into the tap drill hole of PS10035 port, and sufficient force applied to the top of the mandrel to allow the cutter to broach into the counterbore. The tool will broach aluminum, magnesium, and many steels with hardness of 32 HRC or less. APPLICATION: This broach tool, when used in arbor, hydraulic presses or manually, is designed to produce serrations in the counterbore wall of ports prepared per PS10035. 009 between serration major diameter and controlled minor diameter after broaching. Broach Tool - Hand Held, PS10035 Port SerrationsNOTES: Unless Otherwise Specified Replacement cutters may be purchased individually Inspection of noted runout and use of controlled minor diameter per Rosan PS10035 port spicspecification will provide an allowable maximum More.
