Hello! I have Oil Matic MPSD-07-N-CE on my Okuma B200. I dont have any books or manuals for the oil matic and i cant find much on the internet. Found in PDF what MPSD stands for:
M is for...model ?
P is for High Precision
S is for Cooling Main spindle
D is for With tank

Ok so in the morning the temperature shows around 23°C (outside temp is around 20°C) and later it shows around 28-29-30°C.
I also found some settings in the PDF. By holding ENT and changing the next value to 10 (from 11) a new menu appeared before my eyes! It was "C" menu which was set to 45°C !? I set it to 25°C and it was holding that for about an hour (then my shift ended) +-0.1°C. I've never seen it holding one temperature before. Did i turned it ON ? Did i do something i wasn't supposed to do ? What did i do ? May someone explain me the benefits of holding constant 25°C and why am i cooling the main spindle for ?
