High Feed Mill Recomendations

[FTI2007]

Good morning all,

I was looking for recomendations on a good high feed mill to be used to cut p-20 and 4140 using 50 taper hass and a takumi. I wanted to know what you guys are using and why one might be better than another. We currently use mostly ingersoll and seco for our other insertables. It will mainly be used for roughing 3d surfaces. Our company doesnt like to spend money on tooling so we only get one chance at this. Any help would be great.

Thanks in advance.

Mitsubishi has a feed mill that has extra clamps on it that provide a little more rigidity than some of the other feed mills. But we've moved away from Mitsubishi because their tool rep isn't very good.

 

We also use Seco feed mills. They have a more positive rake that is more free cutting.

 

I haven't done recent research into it so there might be something newer that will help you out.

I get excellent results with the Mitsubishi line.

They have hi feed inserted endmills from

Ø5/8- to 1.25 and face mills to 6.3"

The application guides in the Mitsubishi catalog

are the best in the business.

Mitsubishi all the way.

I am using Seco brand of highfeed cutters right now on Ramax and Corrax,

1.0 Dia

1.5 Dia

2.0 Dia

Also on a Takumi V22 and a Awea BM1600

I found some excelent tooling from Kennametal that seems to to do a great job. I have some face mills that hold a variety of different insert in the same holder and a set of roughing end mill from 1/2" to 1-1/2" that all use the same style insert. I just order different grades of carbide for different apps. Best advise is to find a GOOD tool rep. and do alot of shopping to find what best fits YOUR shops application.

Iscar do a new 6 sided insert feedmill. I used it on hardened cast stainless and it kicked arse.

We use the iscars in Aluminum, stainless and Ti. Different geoms and grades of course, but I agree with Bruce, the kick arse.

We've got Iscars here too. I find the Iscars to be tougher and the Mitsubishis freer cutting.

I use a Mitsubishi 2.5" shell mill on a 10" extended arbor to mill a 4.5" x 10.5" deep hole in steel. We use through tool coolant to blow the chips out of the hole. I tried the same toolpath with an Iscar but the spindle load was too high.

We have only used Iscar. While the metal removal rates are awesome, I am concerned about what the tool does to the machine. When running these, it sounds like a little man is inside the machine beating the s***t out of it with a sledge hammer.

[chopsley]

If the part allows it, Z axis plunge cutters just rain blue chips with all the cutting force going up into the spindle. Easy on the machine and super material removal. Of course, many times this style of cutter is not an option. Just say'in.

Which ever one you get, be prepared, they are incredibly noisy. Like Dave said, you feel like your destroying the machine. And everyone in the shop will pretty much hate you. But man do they tear out metal. I use Iscar, But I've heard Mitsubishi is an excellent tool also.

[Ron Branch @ Verisurf]

Currently running Seco on some 45 Rc 4130 at 450sfm and .035 per tooth on a 2" cutter at .05 D.O.C. The pop corn coming of the machine is pretty neat. I took what was a 2 hour run time and8 operation down to 2 operations and 18 minutes worth of run time.

Hmmm- we used a Sandvik 2.5" high-feed mill to ruf down 1200lb blanks of 304ss- 350 sfm, .05" per tooth, .065" DOC. The cutter was nearly silent except near a shoulder or off the edge. Finished part weighed 22 lb, so a LOT of roughing, but not much noise.

What are you guys doing when you get a lot of noise?

[FTI2007]

Has anyone used Tungaloy TXP. They appear to be almost exactly like a mitsubishi. We are having trouble finding a mitsubishi distributor.

[gcode]

They can't bore holes as well as

the Mitsubishi's, but for regular

roughing work, there are pretty good

Do mitsubishi come in inch sizes also or just metric? Where is a good place to find them since no one sells them locally.

[FTI2007]

Between tungaloy and mitsubishi, which one do you think takes less horsepower cutting at the same surface feeds and depths of cut?

 

Has any one used the kennemental high feed mills?

 

thanks again for your guys input!

[MIL-TFP-41]

This guy sells a mitsubishi knock-off that takes the mitsubishi insert. I have not tried the konck-off tool holder, but it might be worth checking out.

Also, Mitsubishi makes a few different chip breakers so some inserts might take less HP than others.

 

I am partial to Mitsubishi stuff....if you can't find a distributor e-mail me.

Iscar & Ingersoll. We use Iscars FF FWX and FF EW style cutters for bigger parts, and their Multi Master line for smaller parts. Work pretty good. We've also had minimum success with Kennametals style.

Just switched to Seco 217/220 high feed mills from mits AJX line, no comparison!!! They cut WAY freer at at least 150% of the AJX SFM too! Less heat in the part and have better insert life, can run at high overhang with a very stable cut. BTW We cut mostly preheat treat in the 30-32RC range and soft A2/D2. I am going to try my 2.00" with a 15.o" overhang next week sometime in aluminum. Also I think that a 0 dergree rake works better on these materials over the positive rake I seen mentioned up there somewhere, positive works good for gummy stuff like alum or stainless though
