My X and Y BL numbers are in the .0005" to .0012" range. Z has a new screw in it. It has 700ipm rapids.
I appreciate your input. I'd say your guesstimate is pretty reasonable from what I've...

I am considering selling my '94 4020 with 28" Z. I would like to get an idea of what to ask for it. I've searched the sold listings on ebay and found 4020s around the same vintage, but not with the...

I have a 4020 with the steel telescoping ballscrew cover on the Y axis. I am having problems with the the cover and aluminum washer getting hung up on the screw about half way back. The cover is...

I have a Kurt HDLM6 that I occasionally use on my VF-O. It will barely fit in the Y axis. I always use it lengthwise in the X.

Thomas,
This is what I used. It is a fly cutter that I welded to a toolholder.

Mill first, then scrape. I milled my table. Only because it was crowned.

Theses aren't mine...

I think you could use "grid shift" to correct for the .027" I think that would alter your too changer height, though...

I crashed Z once and it backed the locking nut off the support bearing(servo side) It made my Z off. You could hear the ball screw slap back and forth when you would rapid Z from + to -.

Can anyone tell me the difference between the PC Turn 50 and the PC Turn 55?

Thanks,

Couldn't you also just disconnet the backup battery, then reconnect it, reload parameters, settings. Wouldn't that reset the clocks?

Brian,
Did you get my email?

Any update on this? I intermittently get the 233 alarm. It only happens when the mill is sitting idle.

Fixed!!! I trammed the head. It was off a total of .001" in the X. I shimmed the head to .0003" total in the X and .0002" total in the Y. Now location on the pocket is within .00025" in the X and...

Geof,
Thanks for the info on grid offset. I tried changing it before you posted and found pretty much what you explained.

Yes, I changed the backlash parameter. My backlash is on...

Dan,
Yes, I checked and set backlash. There was barely any...

When I interpolate a circular pocket, the center of the pocket is consistently off -.0008" in the X. It will be well within .0002" in the Y. The pockets are round within .0002" If I cut a series of...

I took my screw and bearing block out to replace mine, because I did the support bearings at the same time. I think you coud do it with the screw still attached to the saddle. You would have to...

The reason someone probably told you that is because the manufactured leg could have more harmonic distortion than the legs from the grid. It doesn't seem to be an issue, though. I have a Haas and a...

One very important thing is to make sure your legs are balanced. Think they should be within 5% of one another.

I think there are knobs on the monitor rack inside the pendant. Not positive, though... I replace the tube in mine a couple of years, ago and sort of remember being able to adjust it somehow. I'd...

Doesn't matter

Backlash should also be checked. After you do the AMP Tune, you should also do the Angle Test. This is done to sync your X and Y closer than can be achieved during the AMP Tune.
I agree...

I would just call your local dealer. That is easy enough to do. I had to replace the processor board in my Haas. Shortly after that, I had the 144 alarm. I emailed Haas, they told me to call my local...

I actually cut the table on my Fadal 4020. I used a 9" fly cutter, that I welded and gusseted to a holder. It was crowned about .005" in the the X direction. About the last 8 to 10 inches of the...

Thanks!

Yeah, you guys are right. I have actually used this in the past. I have it in the cheese whiz style can. I get mine from McMaster. I was hoping for something in white...

I have some small leaks in my machines' enclosures. I've tried silicone sealant, but it doesn't seem to last very long. I would like to know what everyone has found to work best.

Thanks,

Machineit,

It happend when I was touching the tools off. I use, and have always used "ATC FWD" or "ATC REV" to select tools(takes less key strokes). Type in the tool number, then hit either key. ...

Thanks, I'll take a look. What is the proximity sensor for that sticks down into the turret? I can see it when the turret slides in and the door opens. There is one pin there that it reads. I...

I have a 1997 VF-O. The tool changer seems to intermittently loose position. It has happen to me twice already while I have been manually rotating the turret in MDI. It hasn't happen during a program...
