Central greasing systems are sometimes seen on lorry chassis.

A further problem if incompatible greases are used, they can harden and clog

It is an old machine. There is a bowl filled with grease connected to a row of 
pneumatic valves so I guess the grease is supposed to enter this block. There 
is also plenty of tubes connected to blocks on the sliding surfaces and I could 
see there are grease on the sliding surfaces. It all seems to be driven by 
pneumatic and I have connected compressed air. One of the valves are marked 
lubrication and I have tried to switch this but nothing seems to happen.


Bijur central lube systems use way oil, not grease.  Grease takes a lot 
of pressure to send through thin tubes.  Bijur and similar central lube 
systems have metering orifices that get clogged when the system sits for 
a long time.  I have not had any luck cleaning them.  Direct from Bijur, 
they are surprisingly inexpensive.  If this is truly designed for 
grease, then I really don't know anything about it.

That's an interesting tool.I have a similar tool that is meant to be 
filled with oil or kerosene and you place it on the zerk fitting and you 
tap it with a hammer.  The force from the hammer
drives the oil into the zerk and blows out whatever is plugging it up.   
It works well and is good for old car and truck suspension fittings that 
have been clogged with rust and dirt.

A lot of those "zerk" fittins are actually for oil.

When buying a second-hand machine tool it is often necessary to
dismantle it to clean the grease out of the oil nipples. (and hope
that not too much damage has happened since it was done)

Re: [Emc-users] Lubrication

I should have mentioned the beam axle was installed in 1849, not sure
if the bearing bronzes have ever been replaced on the beam axle. In my
time (about 15 years) I have only machined one half bearing on a pump
rod that had dirt blocking the oilway, we cleaned the journal surface
with wet and dry about 800 grit and reassembled, no problem since.

it is the regular oiling and keeping dirt out that keeps old stuff running.

Don't over look grease also. Pressurized oil is probably the best, 
however a lot of machines simply have zerk fittings to grease slides.
I think a lot of that depends on the speed that the bearing operates at.

  Do you happen to know how if wear are a common problem for slideways and 
proper lubrication is important to avoid wear?


oil should be oozing out from slideways, if not old oil can be clogged 
in the oil lines.

Yes then I know the name it become easier. Do you happen to know how if wear 
are a common problem for slideways and proper lubrication is important to avoid 
wear?

I have table top engraver with nipples and real machine with some kind of 
centralized system. It is good to know what happen is lubrication is not good 
enough. Increased friction will increase current in servo motors so if this is 
common a meter for used current in servo motors would be good. I however 
increased wear is a problem lubrication must be checked manually at regular 
intervals.

Re: [Emc-users] Lubrication

[Bruce Layne]

I waited a little while to see if any experts provided a definitive 
reference.  This list amazes me at times with the cumulative knowledge, 
and I'm still hoping something is posted that is concise and 
informative.  I know that Misumi provides good technical info for their 
products and I seem to recall them discussing the maintenance and 
lubrication of linear motion systems.  Found it!

http://blog.misumiusa.com/ball-screw-lubrication-tips-application-grease-vs-oil

My simplistic approach:

1) If the manufacturer of the machine or the linear motion components 
recommends a specific lubricant, that's what I use.  Even the expensive 
grease is cheap considering that a little goes a long way and replacing 
motion control components is very expensive and time consuming.

2) Each machine has its own grease gun, etc., stored at the machine.  I 
consider this part of the machine.  I don't want to wonder what grease 
each machine needs, and I don't want to go looking for the right 
grease.  If it's right there, I'll do the proper maintenance.

3) Barring a manufacturer's lubricant specification, I choose a good 
synthetic grease.  It's usually a Mobil product.  I prefer greases that 
are reddish or cream colored, rather than black or dark brown greases.  
I want to see a thin film of grease, but when I wipe off the old grease 
I don't want to see black gunk on the light blue lint free shop towel.  
If I see black, I assume it's some grimy contaminate.

There is a very cursory introduction to grease on McMaster-Carr's site.

http://www.mcmaster.com/#standard-grease/=124w94o

Click the About Grease link.

Grease is basically oil and a thickening agent.  I select a synthetic 
oil base because it doesn't form gummy or varnish residues as readily as 
petroleum based oils.  Similarly, I look for a thickening agent that 
doesn't readily oxidize to form thick gummy residues.  The thickener 
oxidation resistance is one of the columns on the McMaster-Carr About 
Grease information page.

I would prefer a thicker grease because the thinner greases will often 
separate in the grease gun and leak oil all over the place and make a 
mess, but I don't let that determine my choice of NLGI ratings.  
Instead, I choose the thickness based on the application and 
temperature, and I keep the grease gun (usually the small 3 ounce size) 
in a heavy duty plastic zip top bag.

Probably more important than the grease in my opinion is the lubrication 
schedule and overall cleanliness.  I'm a bit of a stickler about this.  
Cover the motion control components if they're exposed to contaminates, 
but don't cover them and forget about them.  Precision motion control 
components require maintenance.  I prefer to wipe the old grease off 
linear rods or linear rail at the end of the day.  Wipe away from the 
bearings using a clean lint free shop towel.  Inspect the wipers for 
damage and replace if needed. Use a grease gun to inject new grease into 
the bearings to push out the old grease.  Run G code that moves the 
machine to the limits to distribute new grease to the linear rods or 
rails.  It's a good idea to run this program at the start of the next 
day to exercise the machine before the start of the next day's machining.

Finally, when we build machines, we have the opportunity to improve the 
motion control longevity by keeping these parts clean, and this concept 
applies even on the simplest machine.  I'm currently wrapping up a 24" X 
24" CNC router build, to be used almost exclusively to cut plastic 
sheets.  The Y axis linear rods are exposed on the side.  Rather than a 
simple spoil board on top, I'm using a 1/2" thick ABS plastic top plate 
that overhangs the sides as much as possible to protect the linear rails 
from swarf dropping onto them.  The top plate has side shields that 
extend upward to almost completely eliminate swarf dropping onto the Y 
axis linear rods.  An air blow off will constantly push the chips toward 
the back as they're produced.  The top plate extends far enough to the 
rear to protect the Y axis stepper motor and the Y axis ball screw. The 
top plate has a vertical back wall to stop the chips from falling off 
the back of the machine.  The chips pile up on the shelf behind the 
active machining area, where they can be easily vacuumed away.  Even 
though the Y axis linear rods are well protected from chips and debris, 
they are easy to access for quick daily maintenance.

We have the similar sort of problem with the axles on a beam engine,
they are plain bronze and only rock with 30 tons of rocking weight. we
actually use a steam cylinder oil for our bearings. It is a type of
oil like the slideway oil that really sticks to the surface and takes
little movement to lift the two surfaces apart on a film of lubricant.

For that application you want "slideway lubricant"

Yes these kind of bearing or whatever it is called used to move spindle or 
table in CNC machines. High friction I will discover although then high wear is 
discovered it is a little bit late.

I expect these flat iron surfaces will be very expensive to regrind and want to 
avoid it.

Hello
The actual service life of wind turbine gearboxes is often well below the 
desired 20 years. One of the prevalent failure modes in gearbox bearing 
raceways is white structure flaking (WSF) by the formation of butterflies and 
white etching cracks with associated microstructural change called white 
etching areas.

Sorry, the return is a bigger hose. The 5/16 cooper tube is the output of
the pump

Re: [Emc-users] Lubrication

[Leonardo Marsaglia]

Here we've got an old Italian lathe that is dedicated to gundrilling and
for the spindle bearings (wich are two roller radial bearings and a thrust
roller bearing), it has a simple oil pump driven by the same spindle motor,
so it turns whenever the spindle turns.

The oil is dripped directly on the bearings but it's an open circuit,
nothing complicated. The oil returns to the pump via a 5/16 cooper tube. I
really don't know wich kind of pump this is, but I suspect it has an
eccentric with a diaphragm.

[Emc-users] Lubrication

[Roland Jollivet]

I just so happened to spend the whole weekend reading about bearings and
lubrication. Here are some articles with discussion on lubrication.
I don't know if the links will work for you. They might get chopped up. I
can send the titles for you to google if this does not work.

Regards
Roland

Do anyone have experience on lubrication of slide bearings, ball bearings and 
such things?

Experience of bad lubrication with destroyed bearings is of particular 
interest. References to documentation is also good and in particular scientific 
articles.
