Why Granite, Not Steel or Marble, Is the Preferred Base for Precision Measurement
A metrology lab in Singapore once sent back a batch of surface plates within a month of installation. The plates looked identical to the ones they’d used for a decade — same size, same grey color, similar price. But readings drifted by several microns whenever the air conditioning cycled on...Read more -
