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.
