      Evening, I have a milling machine that requires oil of 12-15 degrees Engler at 50C.

      Does anyone know how to convert this into a more common viscosity.

      Thanks,

      Chris

          Chris, 12-15 Engler equates to approx 91-114 Vk at 50C. Convention is to quote Vk at 40C thus nearest practical equivalent is a Vk of 150 centistokes. Look for ISO 150. And presumably it's a gear oil? Adrian

            Hi Chris,

            a quick google search found this pdf document (p.5), seems it doesn't go quite as high as you want, but may give you an idea. Here's antoher site that you may find useful.

             

            Regards

              Many thanks for the information.

              I actually found a member on here who has a more modern version of the manual for the Aciera F3 mill it is for and this says ISO 150, so as you both said.

              My next question is I have to buy 20 liters of Castrol Hyspin 100 for my lathe, this is ISO 100 , would this be ok to use in the mill instead of ISO 150?

              Thanks.

                Best to check with Castrol Technical, I've always found them very helpful. Should be OK from the lubrication angle but if there is a pump fed distribution system with orifices to control how much oil goes where the thinner oil will upset the mutual calibrations and may also lead to too much oil being distributed. Can't see the difference being so great as to starve anything but orifice or other restriction controlled oil feeds are something of a black art.

                  If you havn't yet had a definitive response it may help us to learn exactly what this oil is expected to do – I'm sorry but I know nothing of the specific machine & I would not be prepared to concur with your proposal without more information. Is it a gear oil or a system oil? Are any specific products recommended/approved? In principle we should be covering both viscosity (done, although you ask about a lighter oil) and application (which could be specific or multiple, light or heavy duty, etc). Adrian

                    Hi, it is the gearbox oil.

                    I have attached the pictures from both versions of the manual.
