Default Can't Win Some Days

I'm learning a lot... like you hardly need any torque on the thrust
bearing retaining nut on this KMB1. I learned how to make new tab lock
washers too since nobody stocks them, but several say they can get
them... eventually. I even learned what the X axis is supposed to sound
like with good thrust bearings. It never really had any problems, but
its sure sounds a lot smoother now. Obviously the bearings were bad.

With new thrust bearings on the Y-Axis its pretty smooth now too, but
only for about 7/10 of a turn. Then it pulses. Its actually a lot
worse than it was before. Before I could see a little flutter about
every 1000 steps or so on the scope, but the machine appeared to move
smoothly. I guess the Y-axis thrust bearings were so wore out that it
allowed it to move smoother. With new fresh bearings it pulses badly.
And no its not a matter of tuning. As near as I can tell the ballscrew
is bent and its binding as it turns. That would sure explain the
chatter I saw before. Now its unusable.

The bad part is I don't know how to remove the new bearings and save
them. The obvious way to pull the bearings pulls the rear bearing apart
when you take the housing and bearings off the shaft. So... even if I
find a good replacement ballscrew I'll wind up having to chase down
another set of bearings too.

Of course I have one piece to make to finish a job that is just a little
too big for the little mills.

DANG-IT!

I've got some much smaller cheap Chinese double nut ball screws on the
shelf. I'm right at that point where I am tempted to make an adapter
plate to mount the ball nut for one of those, and make my own bearing
and motor mounting plate for the front of the machine. It probably
wouldn't last long, but it should be reversible. I'd have to direct
drive the screw which would leave the motor sticking out in the way in
the front of the machine. Its not a pleasant solution. Atleast I could
make all the parts on the little high speed machines, and then I might
be able to finish my current job.

If you're going to junk the old ballscrew anyway, just machine away enough to let you get the good bearings off.

Dont dispair quite yet...ballscrews can..can be found cheaply enough
both on Ebay and other locations.

That's not a bad idea. Although I also considered turning the bearing
surface to a smaller more concentric OD and using a bushing. Probably
would re-turn the whole end and make appropriate adjustments including a
different size encoder disc though... or a whole bunch of bushings. LOL.

Rexroth Bosch are some of the best ballscrews out there. They are

I have a few used ones collecting dust..most will have about .0007"

need..plus length?

I'll post some info when I have time to pull that part of the machine

Good news. I was able to get the ball screw out of the new bearings
without pulling the bearings apart. I unbolted everything from the
machine and took it out as an assembly. Without everything in a bind it
came apart modestly easily.

If something wonderful doesn't present itself I'll have a go at turning
the end of the shaft down and using a bushing or bushings to bring it
back up to spec. Obviously I'd have to change threads and nuts, but
that's not a huge problem I suspect.

Nothing Huh? Ok, well I need the machine working. I can get a decent
price on a metric screw with oversized balls new from Automation
Overstock. (about 7 tenths backlash) I'll just go that way and make an
adapter, because I need to get the machine going pretty quickly. its
been down for three weeks, and while it doesn't do the bulk of my work
its made me realize how much I do use it. There are somethings that are
easier to do with horsepower than with high speed and feed.

Well in the years we have interacted on-line this is the fifth time you
haven't followed through on something you said you would do for me. The
first time I think was before your stroke so call it 4 times. One in
theory you might still be following thru on so still 3 times. As to the
tolerance... well... if you had something better I could afford and
followed through I'd have bought it. But go ahead and blink feigning
astonishment and superiority. It doesn't matter to me how superior you
think you are in everything you are or do or have. Does me no good
without follow through. I just need to get my job done. With or
without you.

I have seen others post about how you did something or sent them
something so I just figured you didn't like me, and didn't mind wasting
my time.

You do know the original claim of tolerance for this machine in the
manual is only .003, although its always produced better than .001 for
me. Its got a decent screw, but its still only a single nut ball nut.

So, why in the heck do you think I posted dimensions and images at your
request if I had it all fixed. --- Note the lack of a question
mark. That's on purpose.

Have a good life. I have work to do.

Yep.* Lots of options.* I'll look at some of the sources on the PM
thread with more care in a bit.


Rexroth Bosch are some of the best ballscrews out there. They are
commonly found in high end machine tools.* OmniTurn uses them as well

I have a few used ones collecting dust..most will have about .0007"
endplay..* Id be happy to send you one or two..what size do you
need..plus length?

Oh..dont forget proper thrust bearings as well.* This is the sort I
most commonly use:

I'll post some info when I have time to pull that part of the machine
apart again.* Right now I have to get some jobs on the little machines
and keep them going.* Might not be until tonight or tomorrow when I
some have time to disassemble.

Good news.* I was able to get the ball screw out of the new bearings
without pulling the bearings apart.* I unbolted everything from the
machine and took it out as an assembly.* Without everything in a bind it
came apart modestly easily.

If something wonderful doesn't present itself I'll have a go at turning
the end of the shaft down and using a bushing or bushings to bring it
back up to spec.* Obviously I'd have to change threads and nuts, but
that's not a huge problem I suspect.




Nothing Huh? Ok, well I need the machine working. I can get a decent
price on a metric screw with oversized balls new from Automation
Overstock. (about 7 tenths backlash) I'll just go that way and make an
adapter, because I need to get the machine going pretty quickly. its
been down for three weeks, and while it doesn't do the bulk of my work
its made me realize how much I do use it. There are somethings that are
easier to do with horsepower than with high speed and feed.


I thought you "fixed it" so I didnt go any farther.

btw.. .0007 backlash is the point I replace em because they are worn
out. If thats what you are getting from NEW or rebuilt
ballscrews....blink blink..


Well in the years we have interacted on-line this is the fifth time you
haven't followed through on something you said you would do for me. The
first time I think was before your stroke so call it 4 times. One in
theory you might still be following thru on so still 3 times. As to the
tolerance... well... if you had something better I could afford and
followed through I'd have bought it. But go ahead and blink feigning
astonishment and superiority. It doesn't matter to me how superior you
think you are in everything you are or do or have. Does me no good
without follow through. I just need to get my job done. With or
without you.


Superiority? About what?

I have seen others post about how you did something or sent them
something so I just figured you didn't like me, and didn't mind wasting
my time.


Blink blink...huh?

You do know the original claim of tolerance for this machine in the
manual is only .003, although its always produced better than .001 for
me. Its got a decent screw, but its still only a single nut ball nut.

So, why in the heck do you think I posted dimensions and images at your
request if I had it all fixed. --- Note the lack of a question
mark. That's on purpose.

Have a good life. I have work to do.



Dimensions? Images? Where.

You lost me somewhere....I thought you fixed it.

ME: FYI: I fixed that axis a long time ago

John Dookie: Bull****!

Me: Ok. What you think isn't important to anybody anyway.

No apparently you can't. You are the one who went trolling for an old
thread to try to annoy me and then cross posted your tripe to a SPAM
group.

I'd tell you your mom is calling, but if she was it would be for help
because she was be afraid you were coming back.

That is so weird. I never figured you would admit to that. You just
don't have that much self awareness.
