high feed cutters...

[MIL-TFP-41]

just curious...I have used these with success in steel & other stuff ( Mitsubishi AJX to be exact)...has anyone tried this cutter in Aluminium?

 

I figure I can be running upwards or 750~1000 IPM, "IF" it works

[Tim Simmermon]

I ran them in aluminum. Dry machining in steel, but MUST use water with Aluminum. I still kept the feed at about 200 IPM. It's gonna take me a while to build up the guts to push them any faster than that.

 

I use Iscar's feed mill and they have an insert with a more positive geometry. I used that for aluminum.

 

If you get to 750 or 1000 IPM I'd like to see a video of that! And bring extra underwear.

[Tom Szelag]

Intuitively, given how much softer/gummier aluminum is and can be, and the wildly different thermal properties, I just feel you'd run into problems doing high feed at 750ipm in Al.

 

But I'd be very curious to hear the real results.

 

Edit - and yea, if you do, show us some video!!

James,

 

Do a search on high feed cutter. There was a thread about a year or so back that talked about them. I've never seen them run but they sure sound impressive!

James,

 

If you have any aluminum to cut at all, why not go to something that is designed for aluminum. I use Iscar's HeliAlu and cut 750ipm all the time with a 2 in. cutter, but watch out, the chips come come out like bullets. I love this cutter for aluminum.

we use the feedmills, for steels

have machine alum. using std iscar mills

 

if you're mach. mostly alum. buy the cutter like the helialu,

 

IMHO

[Storkman]

I wouldn't think the chips would clear fast enough. I would agree on using a tool designed for Ally Numium.

Ditto, ditto and ditto for all others along this line. HF cutters are for steel and such. I as well just use Iscar Heli, Sandvik (R790), Ingersol (Routermill), carbide endmills, AB Tools, etc, etc. Hitting feeds of 700, 800... 1000+ ipm. Basically, these are the "High Feed" cutters when dealing with "Ally Numium"......

We too are using the iscar helialu in 1.5 dia. Runs fantastic. I have only ran it at 7000 (our max) at 200 ipm at .375 depth of cut. What are you guys using for rpm and depth of cut at 750?

[Psychomill]

Brian, what machine, age and controller are on? You can't just arbitrairily (sp?) go 750ipm. Also need to consider rigidity of setup, tool holding, taper size, HP, etc.

 

[Psychomill]

Hey Thad..... here's some video for Mitsubishi AJX high feed cutters... click on the AJX button.

 

[Thad]

Psycho,

 

Thanks for the link.

 

I was expecting to see a cutter take a .137 chip load! Are high feed cutters the same as feed mills?

 

Here's the old thread I was talking about.

I was just curious bout this. Usually for this application I use a Mitsubishi BDX cutter, 1" dia 2 flute, 15500 RPM @ 450IPM. For this application I need to take light depth of cut anyways & was wondering if anyone had success with a feed mill

[kinglouie V]

weather using the helimill or not I'd recommend polished flutes above all. Inserts or not (E.M.)

[Psychomill]

Thad,

 

high feed ,... feed mills, ... principles are the same. I've ran Mitsubishi's upwards of .09 per tooth. Iscar's feed mills have higher chip loads for start points. I get better life out of the AJX though and if you blow one up, Mitsubishi replaces the body for free. I have tried to bring feeds up and down to try and run "balanced", toe to toe testing between the two. But for me, the Mitsubishi ends up ahead. I do have friends that have better luck with the Iscar though. I think its definately stuff you gotta play with to see what works the best for you. I'll see if I can dig up an Iscar demo for you...

 

[Chris Rizzo]

Hey Psycho, is mitsu still doing the replacement in your area? "Supposedly" they are'nt doing that anymore out here....

 

that or I've used up my alotment

Hi,

 

Look it will work but i do not see the point. A feed mill can only take 1-2mm depth of cut, Sure it can feed at 2mm per edge but this is not the best way to machihne AL in my opinion.

[Psychomill]

Maybe,... maybe not.... Say you could feed at 2mm per edge in AL, but not restricted to the low surface speed of steel and it worked at normal or above normal speeds. Now calculate the MRR at that spindle speed and chip load. You're moving some serious material. But, as I mentioned before, why bother? You don't need a "specialized" tool to machine like that.

 

CMR, I just got 2 replacements last week (maybe the week before). Maybe it's a buddy system. We use the snot out of indexable tooling from many brands....
