Pull Studs on CAT-40 - Basic Stuff

[JWB_Machining]

Hey,

My boss got me some new tool holders. I went to put the pull studs on but remebered on my current tool holders my boss applied what I think is Never-Seize (Anti Sieze and Lubrication Compound). I was just wondering if this is the right thing to do and if not is there anything I should apply to the pull stud before screwing it in. Should I really wrench down on the pull stud or just make it snug? Also if I am supposed to apply this Never-Seize is this the kind of thing where there no such thing as too much or is it a less is more application? Any info on Pull Stud methodology and practices would be appreciated, I'm continuing to try n learn something new every day. Thanks

I have no idea whether Never Seize is a good idea or not; I do not use it, just screw the pull stud in dry. I do them tight, and for want of a more sophisticated method just bash on the end of a 3/4" wrench with a plastic hammer.

I use anti sieze on the retension knobs at work. It doesn't hurt anything to use it. If your cat 40 and retension knob rust you will have a problem getting them apart. I also use a torque wrench to tighten the retension knobs to the holders. I torque them to 50 foot pounds. The max torque recommended by US Shop tools for Haas and Fadal retension knobs is 85 foot pounds. They state that under tightening is not recommended but I have never had a problem with the 50 foot pounds. Here's a link to the retension knob section of US Shop Tools if you scroll down 8 pages there is a box labelled: Best Practices For Retension Knob Usage

Geof thats old school, the best way is to hold the cat 40 holder in your hand with a 3.4 inch wrench and smack it on the concrete floor with a twisting action on the cat 40 holder. been doing it that way for years.



I ordered one of the sockets from us shoptools once I get a chance to use it I will let you know how it works.

I can see I am going to be shamed into getting one. To be honest I had already decided to tell my purchasing guy to order one.
