WTB: 45 taper 7/8 face mill holder

leeko · Oct 24, 2019

Hi
does anyone have a 45 taper (Cat45, bt45, nmtb45) face mill holder with a 7/8" pilot they'd like to part with? Not finding many sources for that size. Hardinge lists them, but out of stock and I dont want to think about what they charge...

Thanks,

Lee

I can't help, but I can sympathize. 45 taper? Very rare, at least in my 30/40/50 world. Shell/face mill arbor with 7/8" pilot? Very rare. Both at the same time? Ouch.

If you score a 45 taper arbor with a 1" pilot, you could probably rework it, grinding the pilot and driving dogs down to the 7/8" size.

It'd be a good first project on the tool and cutter grinder

It's not time critical at all - I just have a nice 2.5" Ingersoll facemill currently on a 50 taper holder, I'm trying to switch all my most used cutters over to the Weldon quick change system. Any 45 taper can be adapted fairly easily now that I made a quick fixture for it, so I figured I'd put out feelers for the one I'm missing

Thanks

FWIW I made an extended reach arbor out of a long endmill holder. I milled the end to create the drivers. Then made a plug with endmill flats, .001 oversize for the hole. Pressed the plug in, installed the setscrews, then finished the plug to size and tapped it for the bolt. Works fine.

And yeah, 7/8 in 45 taper will be tough.

You sure that hole in the face mill isn't 3/4"? My 2-1/2 face mill has a 3/4 hole. The next one bigger is 1". Ken

Hi Ken,
I'll measure again when I get back home - after seeing how scarce the 7/8” size is, I'm now wondering the same..

Thanks

I have a pile of CAT45 tooling, will look to see if I have anything you can use. CAT45 was used in the 1980-90s for Cincinnati CNC mills. Perhaps exclusively.

leeko · Oct 27, 2019

Thanks! I may also be on the lookout for some bigger face mill holders. Off the top of my head, I think a 2" pilot is on the "would be nice" list as well

I won't be back at the shop till Thursday to check though

I need some 3/4" shell mill arbors if you have some to spare. Cat 45 was also used by Monarch and Acra.

CAT45 and BT45 is not all that uncommon. I have a couple that size in BT45, but I'm not selling any.

I've seen alot of 80's machines running BT45. I know of 3 shops around me that use machines with it. My MV45 Mori has both BT45 and CAT45 tool grabbers so I could switch over to CAT if I wanted, but I have a truckload of BT tooling.

Not super uncommon, no. I picked up a few lots of holders a while back, but ilmy.collection is light on face/shell mill holders. I have quite a few surplus extended reach endmills holders and tg100 collet chucks , as well as a few other oddball holders, if anyone's looking to swap for shell mill holders

Turns out I have two face mill holders, but they are 1.250 and 1.500 dia. pilots. If anyone needs one or both, or any CAT45 tooling, let me know. Lots of collet holders and long reach holders. Cheaper by the dozen. Some have Cincinnati closing pins. I even have an unused 2 inch end mill holder.

leeko · Oct 28, 2019

I'd be up for grabbing the 1.25 face mill holder, 2" end mill holder, if the collet holders are anything other than tg100 I might be interested (tg75? ER series?), A boring head holder of you have one, and maybe other oddballs depending what you have. I think I'm good on extended reach endmill holders and tg100 collet holders

Thanks!

I think all the collet holders are TG100, I will check. Will take some photos and post.

I found some ACURAFLEX collet holders, two sizes, even. Here also are the others we spoke about. The two inch end mill holder has a V-groove style tool change collar.

leeko · Oct 30, 2019

Thanks for digging out the pictures. I'm not looking to start working with acuraflex - I have enough collet systems in the shop. I also dug through.my stash, and found a 2" holder I already have, so I think I'll pass on these. They're up for grabs to anyone else that wants them

Thanks again

Are you still interested in the 1.25 face mill holder?

leeko · Oct 31, 2019

Ah sorry, forgot about that one. I'll pass on that, thanks again

Hi Ken,

It's definitely a 7/8" pilot. Bugger....

Boy! That's an odd ball one. Should be easy to modify a 1" one to fit if you can remove the keys to turn the OD.
