100sfm??? Carbide inserts, annealed 4340????

Blue chips, thats what you need, that's what you want.

Right now you are at about 355sfm and .002 per tooth, you need more.

Ran out some...

My take on the AC DC thing. I worked where we had an AC machine and now own 2 DC machines myself.

The DC driver boards seem to hold up much much better than the AC boards. It seemed like any...

Yeah, I bought one for $300 thinking it wouldn't be that hard to hook up. Its been sitting out back here for almost 2 years now. Maybe one of these days.

Hydro sweep????

Saw this one earlier and figured somebody else would pick it up, but since you are looking in the morning..... Took me a while to remember my password.

At the "enter next command line"

The only time I've ever seen rust on 17-4 is on a raw investment casting.

Passivation should do it. Look for QQP-35. Basic spec for passivation. DO NOT pay for it. Its been superceded,...

My 2 cents, take it for what its worth.

Looks like a deflection issue, where you are getting the gouging is where the cutter goes from having more material to cut to less material to cut. Also...

Wiperblade sound, I'd say waycover, there are probably piles of chips jammed up in there, really easy to clean out, and they can make a racket when they are moving fast.

If you can go back and...

FadalCNC.com $55 for 2.5 gallons, even cheaper.

Don't waste your money on a new one, they still haven't even gotten around to putting R-8 tapers in there. Pages and pages on B&S tapers, but nothing new in the past 30 or 50 years.

Nail clippers...

You could have had better tool retention sitting up on top of the spindle pulling the drawbar up with your fingers. You'll like it, it will be like a new machine.

One stupid observation that I've...

The floater is what the ball bearings in the end of the drawbar ride on. As the drawbar pulls up, the floater forces the ball bearings inward to clamp the retention knob. The floater also uses two...

Single point threadmilling can be seriously time consuming.

Shotout hit the f/s, thats right where I would be.

Tap it?

or

Spring for a pitch specific thread mill, once around and...

Hey if it works....

Here is a thread from when I was trying to figure this out.
...

Yes the tach can be causing the problem. Are you using the standard glentek motors?

Had a tach go out a while ago. Huge shuttering problem. If you took the MPG and shook it back and forth a...

I second the thrust bearings. Common Fadal problem, especially with the liquid cooled screws. I just unplumb the damn screws. Its a big a$$ screw and its not like its screaming around at 3000ipm. ...

You are going to have to get yourself a gear puller/steering wheel puller with 3 legs. There are 3 bolt holes up on top there, they may have cork in them. 5/16-18 I do believe.

Stack your...

Doh! Oh well for future reference, link to a thread elsewhere, dims of the one you buy, and dims for the one I made that doesn't need a gear puller.
...

try Kmac, or eagle machine in Tx.

I could wiggle the tool in the taper. I've never seen the drawbar loose like you had. I can guarantee that those springs didn't shatter overnight. Did you perchance turn on the spindle with no...

Nice, I've seen worse, had 26 out of 44 shattered in one machine I bought.

# of bellevilles depends. probably 44, the set comes with enough.

47 bellevilles for a 7.5 or 15k spindle, with a...

You have one seriously messed up set of bellevilles. Those half moon retainers should be a PIA to get out, and you should have had to use a spring compressor, you will need one to put them back.
...

Good thing, sounded like you paid a tech to play with lego's.

Crack into that drawbar, its super simple. It really is easy, I was at a point where I could do the bellevilles and the floater in...

Fadal error, I'll get to your problem in a sec, but you actually paid a FADAL tech to come in and he pulled apart the piston, didn't see a crack and quit? and YOU had to check the pressure...

The counterweight is easy to secure and every machine I've ever seen has the bars to retain it in some cabinet or other. They are just a piece of 1.25 or so steel, one longer than the other with a...

I don't know why they call it annealed, its not, its solution treated, ready to be precipitation hardened, and yes it is that hard in the annealed/solution treated condition.

My suggestion, get...

Have a '94 sitting out here in the shop and just wandered out there in boxers and slippers, that parameter is not there.

Fadal Error, I'm assuming you are getting the error on an automatic tool...

The main difference, besides actually going where you want it to, is the rigid tapping cycle. You need to prep it with a G84.1 and then call G84.2, there is a pretty good example in the manual. I'm...

Tmills, that right there, to me, is the main reason that Format 1 sucks.

Swap over to Format 2, life gets a lot easier, some of the canned cycles are a bit different, but the rest is the same...

Had a '97 that was AC on XYZ and DC on the 4th, came from the factory that way, so it can be done.
