At HST we have several housings that allow us to run-up and test certain Okuma spindles as well as some other brands that come in without a complete housing assembly like this Okuma HF-503 spindle.

Our customers will never see the inside of their Okuma cooling jacket. That's too bad, because when they leave HST they shine.
Why is that important? Heat is a major contributor to spindle failure. Any corrosion, scale, or restrictions can adversely affect the thermal transfer coefficient of the cooling jacket. That can result in an excessive temperature rise and a premature spindle failure.
All ports and passages are cleaned and checked All o-rings are replaced and the whole unit is pressure tested after assembly.
If you get a chance to visit Okuma's technology center in Charlotte NC don't miss it. Besides showcasing their high end CNC machines, they demonstrate a variety of latest technology by different manufacturers interfaced with one of their machines.

At HST we repair the spindles that go in these machines. Okuma America began US operations in 1984 in Long Island, New York and moved to its present facility in Charlotte, North Carolina in 1987.
