Hi!
I use LC20 OSP5000G-L, 1984 build. The bed lube tank becomes empty every 5 shifts. About 2 liters spends every 2 days.
Can anybody help me to fine lube timeout parameter?
Looks like the pump works too often and long time of period.
The bed is full of oil
there are 2 parameters.
one is time on in seconds
another is time off in minutes.
I don't have the OSP5000 parameter numbers but if you time the on/off period you could probably find the numbers among the parameter pages. otherwise wait and maybe someone will have the parameter numbers.
I wouldn't start changing parameters. You need to determine ....
1st, what kind of waylube system is on that. Is it the plunger style pump, or the high pressure gear type pump.
2nd, is it a 4 axis LC20. Double the surface to lube on that.
3rd, is there a broken line somewhere.
4th. What waylube are you using.
Optional parameter Word #16 is the off timer (min.)
Optional parameter Word #20 is the ON timer (sec.)
It's better to have too much lube than too little...where are your numbers at now?
Best regards,
The first lathe which waste my oil:Originally Posted by OkumaWiz
#16 = 2
#20 = 0
The second lathe which looks like good
#16 = 5
#20 =0
The question.
If the #20 = 0, it means the impulse width = 0?
How the lube works in this case?
If the #16 = 2, it means every 2 min the impulse rised and inject the oil to bed.
Is it right?
The lube motor is M12 in maintenance manual for Okuma Lc20 (I found the scheme).
The Okuma has 2 turrets.
I can answer only on 2nd question now. We have 4 axis.
On monday I will inspect the pump type (plunger or high pressure).
What is mean what waylube are you using? I don't understand the quastion.
he probably means what type of oil are you using.
lube oil is usually a thick sticky type of oil. one example is Tonna T68
Are you sure of the control & that you are looking at the right parameters? Your numbers do not look Like what should be in those registers...
Otherwise we must know which pump type. I'm thinking you have non-plunger type.
There are different weights of way oil, I've also seen people try to use motor oil.... You need vac2 or tonna 68. The high pressure way oil systems use metering manifolds. Those fail after time and no longer close the piston inside them. It starts by excessive Waylube consumption, then low pressure alarms. People see the total cost to replace the manifolds, so instead try to adjust parameters, then wonder why they need ballscrews or worse. 4 axis machines use exactly twice the Waylube of two axis. 2 liters per 5 shifts sounds pretty normal to me.
1st - Hight pressure gear type pump. (2,5-3,5 MP)
2st - 4 axis.
3th - no line broken and no any leak the oil. All oil is in coliant system
4th - Like in manual, Tonna Oil T68.
Well, a broken line will leak in to the coolant system. Normally you wouldn't see it on the floor, especially X,Z B turret.
Check your parameters as mentioned, but my guess on a machine that old your loosing the "dester" units which have plungers that meter the oil. It only takes one to stick open and go through oil like mad. Again, im not so sure 2 liters every 5 shifts is considered a "lot". I've seen LU45's go through 2 tanks a DAY. thats when you have a problem.
hey guys, did anybody ever get these numbers? I am having the same problem and we cant figure how to actually change the numbers, any help ?
