Hello,
Need some help on this one as it has become very confusing...
A little background on the machine...So, the machine is practically new as it is situated in a university R&D lab, it has about 300 hours on it, but its 2.5 years old. Its used as a research machine however, we do warm-up cycles on it every other day so it stays in good shape. When we bought the machine, in 2017, the manual of that time (before the celos 4.0 manuals) said the hydraulic and cooling oil needed to be changed every 2000 hours of machine use. The techs did not tell us that "machine use" means as long as the machine back panel switch is ON. Anyway, we didnt change the oil for a long time and some problems started appearing.
The first problem was that the turret was giving an indexing fault. We called the techs, they came in and told us that the weight distribution on the turret wasnt even so it was giving an error. They removed some tools, looked at the selenoids, did some thugging on the turret and it started working. So, they left and the next day the second spindle chuck open/close system locked up and both of the spindle brakes locked-up. I tried to find some answers and realized that in the Celos 4.0 manuals, the maintenance booklet was changed and now it stated that both the oils need to be changed every 2000 hours regardless of the machine being ON or OFF. So, I figured might as well change the oils and the filters, so I did. Thats all fine, however, the spindle brakes are still clamped and the second spindle does not open/close. I checked the selonoid switches, they work but, the selenoid valves themselves do not seem to move even though they are energized.
Now, is this problem caused because of a late oil change, or am I looking at the wrong place and its caused by something completely different? Any help would be appreciated. Thanks.
