Experience machining Hiperco 50A??

[ChuckM]

Hello gentlemen!

 

Ok, this is one of those materials I'd never even heard of until we were asked to provide a quote to one of our prospective customers. Stuff's heavy in cobalt (~48%) and I haven't found much info on machining it other than a 25-35 sfm recommendation (double that for carbide).

 

So give me a shout if you have anything to say about Hiperco 50A, I could sure borrow on someone elses experiences here. 95% of this quote will be mill work.

 

Thanks,

Chuck

Alot of your quote is going to depend on your

capabilities.

What kind of machines are at your disposal?

Old machines= old schoolquote.

Hardmill,

 

We use Haas VF2, 3 and 4 machining centers. The 2 and 3 have the 20hp delta spindles (10,000rpm) and the 4's have the optional 2-spd/high-torque gear boxes on them. All are CAT40.

 

I come from a shop that was all Mori, Makino and OKK but so far these Haas haven't dissapointed me too much. Especially when you look at their sale slips.

 

I should also mention that the deepest full-tool cut on any of these parts would be 1/4" max as none of the pockets are any deeper than that. They'd also be very rigidly fixtured. A couple are actually vise/block-stock jobs.

 

Thanks for any help in advance.
