3D printed cutter bodies

I could have sworn that Sandvik has been doing that for a while now, or did do it a few yrs ago. But that's the first time I've seen coolant channels like that. Pretty cool!

This is the company that bought out Komet.
Five years later the Komet stuff that has survived is showing up in the Ceratizit catalogues.
It's been a pain for us as we have thousands of files using Komet chamfer mills of various shapes and sizes.
It looks like they build some pretty nice tools, but as with all tooling coming from Europe, they are
very proud of it and charge accordingly.

That last cut in the video is impressive. That is a big cut in Y+ direction in Ti material in a horizontal machine.

seems like a solution searching for a problem.
I guess at some point the economics will work out.

second thought there is no way in hell you can't machine that on a turn-mill faster and better

1. you can never have too much coolant on the cutting edges when machining Ti
2. the coolant channels in that cutter body are not machinable.
3. they are doing finish machining on the printed blanks.

Speaking of the coolant channels, isn't what they have like the absolute worst spot for them? While spinning the coolant wouldn't even come close to the cutting edges since it's being pushed outward with centrifugal force. I always figured it was better to be hitting the front of the cutting edge as well.

That's what I thought at first, but after thinking about it, wouldn't the coolant only be pushed away while not in the cut? Once it goes into a cut, the grooves in the insert would contain the coolant directly on the cutting edges it seems.

also, the RPM's for a shell mill cutting Ti would not be very high

It would be interesting to try one, but we're not cutting much Ti these days

cross drilled holes with npt plugs FTW. EDM in the unlikely event you cant drill those ports. Nobody is gonna pay 10X more for a 0% improvement in function.

Maybe just people that like Siemens controls.
