Tool Holder material
Tool Holder material
(OP)
Hello,
I've designed a tool holder and a tool for a cutting process in a CNC lathe (using tip insert on the tool).
My problem is to select the best material for the tool holder, and for the tool.
Can anyone give an idea of what type of material should I be looking at?
I need to avoid vibration during the machining. What type of parameters should I look in the steel properties ? Enlongation ? Rm ? density ?
Thanks,
Rjl

RE: Tool Holder material
The second property requirement is compressive strength since the insert will impart compressive stress to the holder. Cabide has good compressive strength but if your regidity reqirements allow Steel it can be heat treated to very high compressive strength. Keep in mind that the heat treatment will not alter the MoM.
One needs to know the geometry of the holder and cutting function to give a more difinitive answer for material selection.
For the insert, I recommend you take that question to the Machines & Machining forum under Industrial/Manufacturing Engineers heading. When you post your question there, give them all the details of geometry, material and conditon (heat treat, form, i.e. forged-rolled-cast-etc) and provide specfics of the cutting operation(s), tolerances, and surface finish requiremnts.
There a lot of beautifully designed inserts out there today so you will likely want to also talk to a vendor to help choose a good insert.
RE: Tool Holder material
We do a great deal of this. If you want to contact me directly I would be happy to talk to you no charge.
We do the tool design free so we can either build the tools or sell the materials for you to build the tools.

Tom:
In this case the tool design is complete, just need the material.
I'm located in Portugal, if we buy the material, would you send us the right spec. for surface treatment/ heat treatment?

I was all along waiting for someone to come out suggesting 4140. But when it didn't I began to woder if I was wrong. I go along with BillPSU's suggestion for most common tool holders.

All our long boring bars are made from Maxel 3 1/2 and are very old.

Now I just need to find the equivalent standards for the steel, here in Europe (I'm in Portugal).
