3D Milling 17-4 ph SS

[Smit]

Hi all,

I am going to be programming a part 5" long, with an elliptical cone shape. I'm going to use a small diameter ball mill to do this job. Maybe 3/16" dia. I am probably going to use a TICN coated mill. Does anybody have experience with a mill that might last longer and give better results? I'd appreciate any responses.

Thanks in advance

Now your talkin thats what i like to hear,I cut alot of 3d stainless,as well as heat treated tool steels with as small as .02 dia balls robbjacks out last all the others ive tried,Thats the reason they do cost some doe.Also OSG makes some phenominal endmills.

Thanks for the input guys. I've called the Robb Jack people and got their recommendations on the tools, speeds and feeds for my applications, and they'll be overnighted for delivery tomorrow. I did have my tool crib person do some price comparisons and the Robb Jack tools are a little higher than what we're paying now, but not a lot. A couple bucks per mill. If they last a little longer they'll pay the difference with no problem.

Robb-Jack has worked for me also. If you have any heavy roughing to do, I recommend International Mini-Cuts (they also work great on titanium).
