Re: [CAD_CAM_EDM_DRO] Advance controls Spindle

I am still playing phone tag with the co. sales rep. to get information. He
said they could not identify the spindles by their serial #. well for the
cost of those things, and for warranty purposes they must. I do have a pix i
will send you. i have to assume its oil mist,the one is labeled HO and the
other port OILM. all the others are not labeled. i just made that
assumption. advanced web site says air bearing lubed with water. I have a
bunch of new 1/8 westwind collets #14839 maybe they would fit your spindle.
