it worked for me rick ,i couldnt see pics though. now i know why he is posting this product over here 14 pages , compared to 2 . not saying the site isnt good rick just not as many horse power junkie's

I still hang out at several sites myself, here included. Sometimes there's info on one that you just can't see somewhere else.
I have forged 6AL 4V bar stock and someone to heat treat them.....just no one to machine them.....wanna try
General grade, good stuff though.
Cutting of the material is not hard i.e. low shear loads. Most of the problems with machining come from it low thermal conductivity, reactivity with cutting tool (smears, galling, destruction of the tool are all signs of this) and it moves away from the cutting tool (its scared I guess) unless you take heavy cuts. Its no more difficult to machine than SS
You need a rigid machine as well, no HAAS junk.
I'm sure someone will disagree with this post though.
yes I agree its a common alloy and there are better ones, but it has better properties than the chrome aloys that rods are made from. heat treat is also key. when I have something heat treated I get a history graph proving time and temp of the treatment. ie . ramp rate, soak, ramp down. doumentation is key with what I do for a living....its proves things were done correctly

I agree.
I cut it often. Big cuts and high feed are fine with the right cutters. The only thing you can not do is run your cutters fast. I think it machines alot like aluminuim but the speeds you run are 10% of what you would run in aluminuim. In a case where your removing a lot of mass from a billet like making a rod. Especially apart like a rod that get heat cycled. I would reccommend rough maching and than semi finishing the rod leaving ..025 clean up stock on every surface. Than vaccum anneal them for 4 hours at 900*F. Than finish machine.
But what do I know.
As Fingers would say.
I do know any time that it is melted it must be kept in a pure att. till it drops below 800F. I usually weld it in a sandblasting cabnet purged with argon. If its a large part I use 2 people holding home build gass difusers and check with a temp stick. If its not cooling as fast as I'm welding then I stop and let it catch up. "But what do I know":hug:

IIRC his family owns a large CNC shop that does work for NASA......correct?

I think Haas is the best machine for the dollar. A good starter machine for the masses.
I liked my 3 Mazaks for cutting and fcontrol features but the dependability was poor.
Over all I've had the best success with Mori. And they have become even better since they hired the lead engineer and his team away from Makino about 6-7 years ago.

Haas is the Corvette of machine tools. Nobody in the industry can touch Haas's size, and features when affordability is taken in concern.
We have a large frame Webb knee mill with a 40 taper, 2 Milltronics bed mills with 40 tapers, and use to have a mid 80's Mazak mill with a 40 taper. None of these machines come close to the accuracy, reliability, power, and the rigidity of our Haas vf-3.
Is there better machines out there then Haas??? Sure, but your going to pay for them. Is Haas Junk??? Not even close.
What would classify me as a machinist?
Somebody with knowledge and understanding on how to machine a part, NOT A BUTTON PUSHER!!
Value to me is more than just $$$$. If it takes two or even three of Haas lathes to keep with a single Mori NL than they are no bargin just cheap. I have a great deal of time running Haas machines. The older ones are far better than the news. The company I work now got rid of all the Haas mills they had because of tolerance issues. All where less then 3 years old. A shop floor full of Mori Seikis now.
I do agree they make a decent starter machine (ie. throw away). The tool room and mini mills are slick. I would not mind having a tool room mill in my garage. But in the market where Wolffy and I compete (Aerospace, and military) I can easily justify the higher startup cost of the Mori because of the far superior dependabilty and capabilty of the machines.
You guys can have all the Haas machines you want.
I am far past button pusher. A true Journeyman Tool & Die Maker. Card and all. But in the end I am just another Pollock pushing buttons to make chips.
