St. Mary Spin Roll Fixtures feature a patented design that uses
three intermeshing contact rolls. This ensures precise, repeatable,
automatic linear positioning and concentricity up to 0.0002" during
precision cylindrical grinding or machining operations. A rotary
"V" Block model is available for inspecting the straightness
of circular or round shaft objects. Ascension Industries, Inc.; NY;
