At this time I have zero cutting tools for my 17" Mori Seiki lathe.
I'll buy some 3/4" square HSS to have on hand but I sure do like the convenience of carbide.
I have extremely limited experience with carbide insert toolholders. I had a set of the 1/2" triangular import holders from Enco that I used on my 10x24 bench lathe that went with the lathe when I sold it.
I suspect the Mori Seiki has the beef and speed (1800rpm max) to run negative rake tooling for roughing, and it sounds like I'd want to run positive rake for finish work.
I'm not doing production work, and much of what I'll do is smaller parts (motorcycle stuff). Is there any sense to buying some negative rake tools, or can I standardize on all positive rake and have it be a little less effective for roughing? Or just use HSS for roughing and save the carbide for finishing?
My Multifix toolholders will easily accept 3/4" tools. I'd have to look but I think I can go up to 1".
I'm not clear on the relative advantages of the standard 60* triangular vs 80* diamond vs the trigonic shapes. It sounds like chip breakers are a good thing to have.
It would be nice if would only need to stock one shape and size of insert for all the tooling, including boring bars, but I'm not sure if that is possible. I know I'll need different nose radii and grades of carbide for different materials.
I presume that if there was a universal insert that did everything there wouldn't be so many different types of inserts. But I'd like to come as close to a universal insert as I can. Getting an insert that goes on sale regularly at a good price would be appreciated.
I want to buy a name brand for the insert holders. Would it be safe to figure that Iscar, Kennemetal, Sandvik, Valenite etc are all likely to do the job for me and I can go with whichever one has the best price?
I'm trying to change my previous "buy cheap" habits and only get good quality tooling for the lathe and mill. But I still want to maximize my bang/buck ratio.
cheers,
Michael
