Just rotate the shaft 180 deg. should be good for the next 20 years or so.

I find over time the lip seals make a groove in the ball screw sealing surface and even with new seals I have dow frost getting to the thrust bearings.
It is a good system that adds accuracy to the...

You might need to reach between the covers with a hook tool to pull the chips out of the corners.
When the lower cover can slide full forward it can be tilted up and out.

Newer machines have a wiper style cover for the Y axis.
I have one old style machine like yours, it is easier to clean as you just pop off the springs and lift off, no bolts to deal with!

You...

Your 1993 machine has a grease pack spindle, pneumatically operated lube for the ways and screws.

Your 1985 was originally air oil spindle, the mist unit should have spindle oil. It may be...

I would look at the survey for that axis, you can comp for errors starting from the X- limit. We had a similar condition no backlash but over .010 accumulated error at full travel.
The screw is worn...

They are using the high torque Fadal hi-low belt drive and spindle, I think that was a good choice as most new 40 taper mills are direct drive now and can't run large face mills and drills at high...

Should be a ~.050 side hole in the push out rod that bleeds air down the drawbar for air blast at tool change .
It is not a high power blast like some machines with on board air surge tanks.

Could you share what problems you are having?

It would be nice to have that control as a option by some of the machine tool builders. My guess it would have to be a builder that already offers control options like Feeler, Sharp or SMTCL.

If you need to test the door interlock switch pull the J13 connector from the lower corner of the mother board. This will disable the door interlock system for testing.

Don't forget to re-install...

I have had a few do that after 20 years of tool changes, replacement is inexpensive.
Keep your tool out pressure under 120 psi will help, never seen a broken piston damage anything else.

The...

I have several machines with those but never had one apart. I know Fadal did not manufacture their side arm tool changer, it is imported from GIFU Taiwan Gifu Enterprise Co., Ltd. I have seen...

It sounds like a turcite problem not spindle tram to me.
If you jog a indicator around the table and one corner is low, the turcite has been damaged and worn away allowing the table to sink.

The...

It would be interesting to see if they build new machines in Chatsworth.
Fives also owns the huge Giddings and Lewis plant in Fond du Lac Wi. along with their foundry in Wi.

Hopefully they can...

I called the Chatsworth office and was told they are planning on building machines again. Looking at 4th qtr. 2014 or early 2015 to have product available.

That is good news for me I could use a...

The high RPM opens up the taper a little witch takes extra force to break loose, this is normal for a Fadal.
Some graphite spray on the taper shank will help.

I talked to Fives at Westech 2013 and was told they were not doing anything with Fadal other than supporting parts and service.
Do you have any other information?

Some EMC, TRM and linear way mills had grease fittings standard with the PDI lube system as a option.
If yours has PDI to the screws it has been updated or was factory optioned with the lube system.

The other controls are Fanuc Oi on the 3016 and Fanuc 18i on the 4020. I talked to Fives at Westech 2013 and was told they were not doing anything with Fadal other than supporting parts and service....

A week amp chassis would be my first guess. The big caps go bad with age.

I reccomend you use Gibbs to send to your machines. You are already there making your programs.

In Gibbs go to settings, communciation and create a profile that matches your machine. Baud rate...

Check the thrust bearing first. This is a common failure point and will usually
make more noise in one direction.

Use as strong a magnet as you can find (rare earth type) to pull the balls
out of the spindle groove into the floater, grease and damage may prevent
the balls from retracting

The floater can get...

One item to check is if the idler wheels spin free. Remove air pressure from the machine, if a high torque machine you can release the hydraulic pressure by pushing in the pistons that the high...

Bwana Don Nice perspective, Well said!

I had this same problem 4 or 5 years ago. On close inspection the plastic
coil had a small crack in it. CRT coils are verry high voltage and will short to ground if they can. I mixed up some 5 min...

I have a old tool holder with a .050 washer under the retension knob
that I use to check the condition of the drawbar springs.
If this holder is not tight in the spindle I know to change the...

INV-077 (Yaskawa) is what the newer machines 2003-up in my shop have.
No failures so far with the Yaskawa, I have had AMC inverters last from 2yrs to 15 years and still going.
