Selecting A Parting Tool

[EdK]

Ken,

My lathe is a 14x40 with a 2HP motor. Do you think the parting tool I have is a good match for the lathe? .094 seems kind of wide.

You should be just fine with that, Ed. Give my speeds and feed a try on the 1144 you got and let us know if you end up with a parted workpiece or a two-piece insert.

I'll video the experience. I think I'll start out easy using the cross feed and part some aluminum then some 12L14 and then try the 1144. Maybe I better check and make sure I have a clean pair of underwear just in case the installed ones don't survive the ordeal.

Aluminum may not work the same. It's so soft that it may not break a chip at all.

Just use the 12L14 first.

[EdK]

OK, I went ahead and tried parting off using the power cross feed. It ended up working out very nicely. The narration on the second part of the video kind of sucks, I was stumbling over my words, but I think you'll get the gist of it. I have to thank Ken for motivating me to try it out.

Well done Ed

If I only get to say one thing a bout Ken - he certainly knows his stuff.

Thanks Darren, and you're right, Ken sure does have an enormous amount of knowledge when it comes to insert tooling.

That's just beautiful Ed! I'm not sure where you were at for feed rate, though I believe you could use up to twice that feed without any issues. You could also use more speed if desired, and that would put more heat into the chips. Anytime you can get the chips running straw to blue color, you're carrying most of the heat out of the cut with the chips and saving the workpiece and stock from getting hot.

I really don't know all that much, just know how to put on a good show. I'm in sales, remember?

Nice demo Ed and I'm glad you didn't need that spare pair of underwear.

Ed,

Should you see a need to get deeper cutoff capacity, I'd encourage you to keep your eyes open for a deal on this exact same type of tool holder. I have 3 of them, and they get a lot of use. There are two most common sizes of the indexable insert blades for these. I have two that take the smaller 1" (26mm) blades and can also use down to 7/8" HSS blades, and one that takes the larger 1-1/4" (32mm) blades. The blades don't have



There may be a blade from Kennametal that takes those GS inserts, though I've never seen one. Their standard offering is the "A2" system for spring clamp single ended inserts. I use the Valenite "VSG" (single ended) and now obsolete "VTG" (double-ended) systems, though they are compatible with the Sandvik Coromant's 151.2 (single-ended) and 123 (double-ended) systems and I'll be able to get inserts for long time.

I don't recall which size QCTP you have on your lathe, but it appears from the video that it may be the "BXA/200/25" size that accepts up to 5/8" tools. If so, here's the Dorian holder that you'd be on the lookout for:
