I got a new lathe coming .Its a Grizzly G0602 . I will be putting in a 1hp 3phase motor with VFD and CNC'ing it soon . I have a AXA toolpost and will be using 1/2" tooling(I know i will have to mill the shafts down a little). I will be cutting 6061 aluminum and Stainless mainly (303,316) .

Looking for toolholders and inserts but with the vast amount of different ones im totally clueless. Im not looking for the best but not the worst either. Just what works. Positive rake i think i will need but thats about all i know.

What toolholders and inserts should i go with for aluminum and which for stainless? Looking for turning/facing tool holders ,parting toolholder and threading tool holders and inserts.

What ya got?

You shouldn't need to mill down tool shanks.

I use an OXA toolpost on a 7x14 with 12mm tooling (1/2" ) with no problems.

I'm quite happy with DCMT inserts. They are 55° inserts which means can approach a shoulder well.
I bought mine from ctctools.biz

If you Google a insert tooling nomenclature chart it will make it easier, both the holders and inserts follow standard codes.

not sure what your budget looks like, but I've been using an insert like this on 6061 t6 with very good results. I use them on a EZ path lathe and can make some hefty cuts and then finish with the same insert.



hope this helps

I know they will fit in the holder .I have a oxa and axa .The reason i said i have to mill them down is they sit above centerline.

Nice finish. They may be just a little above my budget considering i need multiple tool holders and multiple inserts for different metals. Im not sure i can do 40.00 a insert.

[pippin88]

No problems with getting them centerline on my combo, I would have thought the larger toolpost + larger lathe would have the same.

[chrisnis]

Its a known issue with AXA toolpost and G0602 lathe. G0602 lathe has a bigger taller compound then a 7x. Also in some cases non lathe specific a carbide toolholder is not exactly 1/2" and slightly bigger so it wont with in the QCtool holder but i was mainly talking about the AXA G0602 issue.

Whats a decent tool holder that uses DCMT or CCMT inserts?Are there any tool holders that can turn and face without moving the tool?

How are the Shars toolholders ? Worth getting for at least the lesser used ones? I could also put good inserts on them ,no?


heres some tool holders i have been looking at.Are these any good?

Also i was wondering .Are the same carbide toolholder/inserts used for manual lathes and CNC lathes or does cnc require specific toolholders/inserts/? I am thinking with CNC i would want a toolholder/insert that can do multiple operation with one toolholder/insert,no?

If you have any questions on being on center line you can always skim the under side of the tool. and then use shim stock to bring it back to center line if needed.

That is my plan

Or you could just mill a couple of slots into the compound to let the tool holder sit a little lower. That will leave your tools standard and you won't have to shave each new tool. Eventually, when CNCd, you will remove the compound entirely.

Those are some nice looking toolholders, I'd get both plus the dcmt toolholder.
You can face and turn with the ccmt when cnced but the dcmt will allow putting some shapes in the mix without changing or adjusting the tool.

Awesome .Should i get the inserts from them too or should i pick up inserts from somewhere else ? not sure what brand inserts they are. Everyone seems to like latheinserts.com. Whats the difference between the 21.51 and 31.51? I think i am going to get all three since i cant find anything else but shars easily.

Thats a good idea .

The thing i mostly dont understand with tool holders and inserts is the rake angles and what to look for. I read you can have a negative rake holder with positive rake insert and still becomes positive rake overall .What if you have a positive rake tool and positive rake insert? A lot of the tool holder iv been looking at however dont even list the rake angle,just the inserts do. I think the more i read the more confused i get on what i should get.How does one go about matching inserts to tool holders?

Hoss2006 i seen in your vids you use a insert with top and bottom usable. These are negative rake inserts correct? What tool holder are you using them on ,neg,positive? I was under the impression that negative rake inserts was a no,no on the G0602 and only for huge machines.

Also i really like the threading insert your using. Do you have a drawing by any chance for the toolholder you made for that Aloris threding insert?

maybe you guys can clear up some of my confusion .Iv litterally been reading and looking at tool holders and inserts for the last 10 hours and getting nowhere fast. lol

I think you mean 32.51, not seen any 31.51.
The first digit is how wide the insert is in 1/8ths so 1/4 vs 3/8.
The 2nd digit is how thick by 1/16ths, 1 = 1.5 so .094 an 2 = 2.5 so .156
These are pretty standard but there are some variances of what the code number multiplier is, valenites which I use mostly
a 2 = 1/8 thick.

Yes the inserts I used are double sided zero clearance angle and the toolholder is negative rake, bigger cnmg432's though.
Negative rake is preferred for harder metals, roughing, positive rake for softer materials or fine finishing steel, zero rake for threading and parting.
There's some good info here.

I'll have to look for the threading tool holder print and get back to you.
Toolinghouse has some good insert prices.

Which of these inserts will fit the tool holder below
snmg insert | eBay

1 2 x 4" RH LH MSDNN Indexable Turning Tool Holder SNMG | eBay

[hoss2006]

An snmg 322 would be a good choice.
3 = insert width in 1/8ths or 3/8 inch
2 = insert thickness in 1/16ths (for inserts wider than 1/4) or 1/8 inch
2 = corner radius in 1/64ths or 1/32

the 3 and 2 are needed for this tool holder but the 3rd (2) is your choice of radius
1 = 1/64
2 = 1/32
3 = 3/64
etc.
