Hi guys,

We are very new on CNC lathe. We just got one simple 2 axis cnc lathe . Can you, lathe-gurus ,to give some advise what type (kit) of cutters –holders we have to buy for general use - just to start .

I am so sorry if my question looks stupid to some one .

Thank you in advance

For general purpose turning, you would want to get an 80 degree diamond style tool. I prefer the trigon style toolholders where you get 6 corners per insert. You would also want to get a 55 degree tool and possibly a 35 degree. A part-off tool is generally a common tool. OD grooving tool where you can use grooving inserts as well as threading inserts. Boring bars are dependant on the type of work you do.

 

For turning tools, my preference is Kennametal, Sandvik, and Seco, but there are tons of great choices out there.

The 80 degree CNMG tool will most likely be your bread and butter tool (depending on your work).

Cobalt coolant thru spade drills are nice and cheap (we use the Acme brand)

Sandvik has really good tooling for Stainless Steel,and really good carbide indexable drills.

Give them a call and have a rep come out and give you a quote to tool up your lathe.

A combination cut-off and bar-pull tool is useful.

Here is a video of one in operation:

Make sure your tool holders and tools match. If you are using metric tool holder you need metric shank tool holders.

 

If you do not do this you have to shim or machine the tools to get them to center.

+1, CNMG 431/432 holders are throughout our shop, CNC and engine lathes. 4 good sides, tons of different MFGR's make the inserts and the holders. I get the kennametal in KC850 for just under 5 bucks each thru Hemley Tool and at that price we do just about everything with them from aluminum to 300M.

 

I have boring bars from 3/4 dia to 2" dia that take the same insert.
