Slotting tool reccomendations , please

[Charlie Pierson]

I need assistance finding a tool to make a 3/32 full radius slot about 7/8 deep and 2.5" long in C1117.

 

I figure I'll need a 4" OD cutter if the bore ID is 1".

 

I would prefer that the cutter uses inserts but will settle w/ solid carbide as the job is a repeating

and somewhat high volume job.

 

The feature is a relief groove at the bottom of the 'V' in a V-block.

The 'V' and slot used to be cut on the old gang-millers and now that is no longer an option.

 

I am temporarily using a 3/32 ball emill and it is a very slow process.

 

Can anybody point me to any cutting tool manufacturers who might have such an item ?

I have looked at Sandvik, Iscar, Seco, Robb Jack, an PH Horn so far w/ little luck.

I would try AB tool, we have them make full radius woody cutters all the time, although they are brazed carbide. http://www.abtoolsinc.com/

 I was looking for something like that for some titanium parts I have to make, ended up getting carbide tipped tools, but these would have been cheaper...sigh...

Oh well, next time.

so basically you are wanting to cut a full radius corner Woodruff key seat ?

[jlw™]

Keyseat cutters for me are moon or Harvey.

 

Moon will get it to you asap. Harvey makes a better tool but it may be a week or two on special tools.

Mike, basically that is what I want to do w/ the exception that I have to reach over the high part of the 'V' to the center of the 'V'

which will require a cutter diameter of 3" to 4" depending on the diameter of the shank or arbor.

 

Ron, I'll check the link as soon as I get back from the trenches.

 

specv, ditto w/ AB

now to reduce wear on a brazed cutter you could rough it with this: http://www.kennametal.com/en/products/20478624/57493250/556247/46610642/46659698/46660235/100000571.html

 

which is an insert cutter and finish with a full rad AB tool.
