highfeed Ti

[Surface]

The highfeed milling cutters are impressive when moving a lot of steel, but in the catalogue, I don't see any speeds/feeds listed for cutting 6al-4v. Anyone have any experence they could share?

What type of cutters are you using? I have a customer that is cutting alot of Ti and I have a tooling list of solid carbides which has some speeds and feeds that they have run and tested.

In a 40 taper machine 10K max rpm , I'd like to use this 1.25 Mits AJX for roughing and finish with a .250 flat and .500 ball.

I probably use either SGS-Zcarb or Niagra Stabilizer with TiAlN for finish.

Machining quite a bit of titanium here and none of the tool company ever offered me a high feed cutter to test. I would doubt on the tool life. They must be about to come up with something. So far variable helix or double variable helix end mills works very good for me in roughing (slotting, pocketing, etc...).HTH!

If the AJX cutter would work, this would be an ideal application. I need to remove 12 pounds of material per part. And in Ti, 12 pounds is a lot of material, something like 70 cubic inches.

I have trialled Iscar's feedmill in 6al4v and it worked a treat. Cutter: FF EW D25-050-W25-06-C Insert: FF WOCT 060212T IC928 Cutting speed 40m/min feed per tooth 0.60mm DOC 1mm WOC 19mm

Flood coolant. We probably could have increased those numbers 50% and still had acceptable results.

My ISCAR rep told me 450SFM .05 chip load on a 1.25" feedmill. I don't think it is going to work in this material.

 

I think I will try your numbers.

There is a distributor here in toronto that sells endmills they produce in house. The 1/4 flat will remove 6AI-4V at a 160-190SFM 2450-2900 RPM 8.0 IPM with a 1Xdiazal cut with 100% radial step over. Now if you are willing to go to the 1" endmill the feeds for the same cut are 610-720RPM 9-10.5 IPM The company is calleed True-Broach Machine and tool and if you like I could send you there information. I don;t have a quote for either of those cutters but I use the 1/2 all the time and this cutter is awesome and is only about 20% more in price to the standard all purpose ones KBC sells

Within a thou,

Please do. I am wanting to go with some 1 inch tools for finishing. 10IPM was my target I was hoping to get to. My E-mail is

I will just post it here. These cutters are great I put them against Hanitas Hifeed endmills and they don;t even come close. The companys adress and phone number are

I sent an E-mail to True Broach this morning.

Thanks for the info.

I talked with another Iscar rep Friday morning and he suggested 130SFM max and .05 feed per tooth. Which works out to 397 RPM and 60IPM. I have tried these now and I am still only getting about 5 minutes on the inserts before we have to roll them. They seriously underbid these parts and I need to get the run time down as low as possible.

 

Later,
