I'm looking for a single tool that I can use to profile the entire face of this part (6061). Kennametal has a boring bar that uses a 35 degree diamond (Kennametal part number A10SSVMBR2E), and has a -50 angle on the front. Seems like I should be able to rough out the 'outer' portion by plunging and facing on the +X side, leaving a cone of material around the hub that I can't reach while the spindle is rotating CCW, then reverse the spindle and use the same tool to remove the cone and cleanup around the hub while working on the -X side. I know the interrupted finish cut will leave a tell-tale line, but I can live with that.
I saw that Mitsubishi has a new tool that uses a 25 degree diamond that may work even better than a 35 degree, still waiting on the sales guy for details. Anyone know of other boring bars that will get in there to work the face from both sides of X?
This a gang tool lathe, and the part is on the large size for the machine, so I need to do this with one tool in order to have enough room to mount the other two tools necessary to finish the part (drilling type boring bar for the hub ID, grooving tool for the OD)
FWIW, I could not find a face grooving tool that would do this job. Please ignore the tight radii on the drawing, I'll be opening them up as far as necessary.
If you've got a better idea on how to do this, I'm all ears.
