Good day , We also have problems with hardened threads if they are tightened up
without lubrication, we use the stainless steel anti seize paste. Just a thin smear is all that is required . The male thread, we have cleaned up with a small hand grinder, pita. Usually the nut has to be replaced. john ________________________________ From: Todd Zuercher <[email protected]> Sent: Saturday, 4 February 2017 9:01 AM To: Enhanced Machine Controller (EMC) Subject: [Emc-users] Tool holder threads? Does anyone here know if it is possible or practical to salvage a tool holder that the threads have gotten messed up on? We have a Techniks HSK63F tool holder that some how got buggered up to the point I couldn't hardly get the nut off. The 1st 3 threads on the nut are galled up pretty bad. The things cost about $350, so I thought it might be worth asking. Unfortunately we are a wood working shop so I don't have any metal working machines, so I'll be stuck with sending this out to get done (if there is anything to be done.) Here is what it looks like. https://s28.postimg.org/e4ip0y57x/0203171628.jpg Next question, Any guesses why it would have gone bad? We always tighten the nuts at a workbench with a torque wrench, to 90ft/lbs, so I don't think it was ever over torqued. -- ======================================== Todd Zuercher mailto:[email protected] ======================================== ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users [https://s28.postimg.org/e4ip0y57x/0203171628.jpg] ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
