Starrett Crystal Pink surface Place

  • Accurate for use in metrology laboratories and wear resistant for use in
    abrasive shop environmentsThe finest, most durable granite surface
    plate available to industry today
  • The name is derived from the fact that it has the highest crystalline quartz content
    of any granite surface plate

Surface Finish

  • Even distribution of large quartz crystals provides a smooth finish, which
    significantly reduces wear on the surface plate and the instruments used on it
  • Fine micro-finish, combined with the natural voids in the surface, prevents
    wringing and provides a velvety-smooth tool action

Wear Life

  • Non-quartz-bearing granite in average daily use requires resurfacing about
    once a year, while Crystal Pink ® plates used in these same plants have required resurfacing only once every three to five years, on average.

Starrett Crystal Pink:

  • Meets or exceeds U.S. Federal Specification GGG-P-463c for flatness
  • Great surface hardness and wear resistance – the highest percentage of
    quartz crystals of any granite plate
  • Smooth, jewel-like quartz bearing points protect accuracy and finish of both the
    surface and the tools used on it
  • Quality and economy combined Comparable to black granite plates while
    outwearing them as much as 5 to 1
  • Meets or exceeds 50 lb per square foot (24kg per 1,000 sq. cm) load bearing
    specifications. Available in 100 lb (45kg) test series
  • Standard-size plates are mounted on resilient support pads, providing isolation
    from normal vibration and a non- distorting 3-point suspension.
  • Packed one per crate with skids for forklift handling.
