Hi all,

Glacern is having a pretty significant sale (http://www.glacern.com/deals) on their feed mills.

I have a WMD30LV mill/drill. The manufacturer claims it's a 1.1kW motor, which is a little like Sears claiming my vacuum runs a 1 HP motor. So I'm guessing a feedmill really isn't for me...

The inserts are $50 each and the screws are $5 each. With the holder that is $150. Is that really a good deal or did I miss something?

$50 for a pack of 10 inserts. Not terrible. But they are on sale. I dont see anyone else selling them either.

Check the website for a picture of a "feedmill". Apparently, they only come in 1" diameter. It's hard to tell exactly what their purpose is.....boring, drilling???

But, they are definitely discounted, $200 reduced to $40!!!!

There really is a thing called a feed mill on their web page. It looks like an indexable end mill, but not really sure what it is supposed to do. Except maybe it doesn't guarantee a 90 degree shoulder. Also, why does it have both an insert screw and a clamp? For $40 that's a pretty good deal.

Yup, feedmill as in elevator.

List price is $200 for the mill and $200 for 10 inserts, on sale for $40 for the mill and $50 for the inserts.

I think a (metalworking) feedmill is for rapid removal of largish amounts of stock.

If nobody knows for sure, I'll call Glacern and ask.

Thanks Tait.
I always say it's not a good day if you don't learn something new. I hadn't heard the term before but I know what it means now!
Sounds like a helluva deal to me as I've always been impressed with Glacern's quality.

They look like they might be used for 3d contouring. The inserts look like they would only allow a depth of cut of about 1/8" or so. Not really what I would call "hogging".

The trend in CNC hogging is in the Z axis or vertical. It is like drilling except you only do a partial step over rather than full diameter. It looks like these would be suitable for that method, then contouring to finish up.

Excellent price on their vises too.
I'd buy that feedmill but I just can't imagine what it would do that i can't already do with an indexible endmill.

Feedmills are for Cnc, mostly pocketing. The idea is to use shallow DOC and high feed rates to move materials fast. Most cam packages now have special feed mill tool paths for optimal material removal.

High feed mills can also be very effective in plain ol' face milling to acheive very high material removal rates with lower forces and lower HP per cubic inch of material removed. This is a video I took at a friend's commerical shop. They use a Walter high feed mill to mill about .200"-.225" off the face of some A36 hot rolled steel plates that are about 18" wide x 13.5" high. It's ony a .075" depth per pass with a 6" diameter 10-insert cutter at 3.65" stepover. Notice the plate is held on a pair of magnetic chucks, though there's one 3/4" dowel pin in each to kep the part from rotating. Feed mills should put 80% or more of the cutting force straight back to the spindle axis, little side force.

The old standard of "about 1HP per cubic inch per minute" is blown out of the water. At 440 inch per minute feed, this is taking off 112.3 cubic inches per minute on 50HP rated machine. It's just two of three passes, so a short 48 second video. Sorry for the really poor cell phone video, it's all I had.

So these will work on a Round column mill drill then?:D

If you can crank the handles fast enough!

That video is pretty neat. At first I thought you were holding the camera sideways, then I realized, Oh, HMC.

Yup, it's a horizontal machining center in a 3-machine cell, common pallet rack and 180 tool magazines on each machine.

That's the thing about high feed mills....I can't feed them fast enough even with the power table feed on the Bridgeport in RAPID.

If you have a CNC machine with programmable feed rates of 70 inches per minute and higher and at least 3HP spindle, there's a chance you could use HF milling cutters. They are also commonly used for helical milling of holes, and they are excellent as a plunge mill. You don't need high feeds for the last one.
