Hello again everyone,
I picked up this K. O. Lee CO. Surface Grinder, the badge is missing, but looking at images online, I think it's a S718 6" x 18" ? It is hydraulically and manually controlled. It's VERY dirty, but pretty much rust free.
I'll start with my question first: Is there any oiling provision for the spindle on this type of machine? I sure don't see any.
So far, everything has been very stuck, it has clearly been sitting for a while. We hooked up a 3 phase 220v VFD to the hydraulic pump motor, and eventually got it to spin. The oil is in dire need of replacement. At first, the X and Y axis would only move in one direction. We eventually pulled off the cover, and removed the valve assembly for the Y axis. The two valves were not rusty at all, but stuck in the bore. A bit of percussive maintenance freed them up, and after reassembly, the Y axis now moves as it should. I'm sure something similar is the case in the Y axis, but I haven't opened that part up yet. The Y axis rack has been destroyed, as well as the X axis half nut, but those are things I can make or purchase. Back to my question, the spindle turns free, and I'm ready to test the motor, but I'm afraid to run it before knowing if the bearings need oil. I'll post more pictures I took from under the cover later on.
Thanks!
