SCORE!

Those kind of machines are a good part of reason why commodity cutting tools are so cheap when you subtract raw materials cost

We had a couple of 9axis huffmann at the lazy B back in the day; mostly, we used them for semi-production regrinds of carbide endmills so they were grossly under-utilized IMO

Anyways, if you get a chance, take a look at some of his other videos--a exceptionally creative individual whom I'd hire in an instant if he came knocking.

Personally I would suggest a 5c setup or at least a 3-jaw with freshly = re-ground masters but in reality, the larger the cutter diameter, the = less important it becomes to be perfectly centered; where you are mostly = hogging aluminum for instance with say, a 1in dia cutter at .030 IPT, = then 5 thou of runout is basically inconsequential.

Also, you might be surprised at how accurately most new, medium quality, =

3 jaws will repeat out-of box up until they finally get whacked a good = one.

volley=20

increasing=20

Okay, just wanted to make sure you were clear on that..

BTW, cobalt end mills are a bit more difficult to grind, the word = "tougher" being an apt description...spark color, pattern and intensity = is also bit different.

Anyways--likely it won't take you very long to notice that, when = sharpening, they actually do "feel" a bit different as compared to = M2--after which point if you ever happen to unexpectadly encounter one, = you'll probably realize it fairly quickly.

Here, basically you have to challenge each and every new assessment or = else it just keeps piling up....

IOW pretty sure no provisions exist allowing for adjustment of a levy = that's more than a year old.

--definitely something to check into, since history tends to repeat = itself.....

Thank you. Again, good advice. I use 'em. I've never sharpened them.

Lloyd

Ok. Thanks. BTW, the grinder I'm talking about will be in the Amada Machine Tools booth at IMTS. It's called the DV-7M. Tell them I sent you.

I own that exact chuck. TIR ain't all that good.

Lloyd

Usually, I make the boss on the backing plate a tad undersize....allows = a few thou of radial clearance between it and the chuck body--then, when = I mount the chuck, I use an indicator and tap it around so as to = carefully position it dead true to the spindle bearings before finally = tightening the mounting bolts....finally, I'll use a ring and then a = spider, grinding the master jaws with a tool post grinder, in two = stages.

This does two things...

First, it balances the chuck which, if it happens to on a lathe, keeps = it from shaking up your beer and walking across the floor when run at = high speeds...

Second, this leaves you with a bit of a a kludge factor, allowing you to = bump it around a little in case it's only accurate within a certain size = ranges ( damaged scroll ) or where it's taken a substantial hit, but you = don't currently have time to go back and re-grind your jaws at the = moment.

Gotta think about that one. What happens on interrupted cuts?

Lloyd

Nothing..

Unless you're running so hard that you're basically ASKING for something = to go amiss...

I wonder what this is appraised at:
