Need Help!- Stellite machining

[Andrewchin]

Dear all:
I am cutting stellite 6, but so many difficultys@_@. e.g. wearing, tipping and breaking of tools, parts deformed etc.
I'm sure here are friends who have experience in cutting this stuff and i beg your suggestion of the hour. any info about tools or machining parameters is greatly appreciated。
Thanks a lot.

Yeah, REALLY REALLY SLOW. I've machined Stellite, Hastaloy, Mastaloy and other nickle alloys, no fun unless your working for someone else.

Cermet inserts and carbide drills... Hope your turning it, and not in interupted cut, I would hate to mill that stuff.

I really appreciated your assistance, i have tried to use ceramic tools， but they were all damaged easily all the time。 would you explain in details about the model of tools.
thanks very much.

What are your symptoms? What SF are you running...speed feed.... Most materials like this require a low speed high feed. 50-70sfm .005 chip load IIRC

I took a high speed milling class at Macomb community college here in Michigan. A high level iscaar rep taught the class. Often they will come out to your shop let you try out tooling and they always solve your problems.

I know this is an old post, but I machine stellite 6 on a haas vertical mill. The tools that seem to last the longest are uncoated solid carbide, with a very low feed-rate.
