Design
Workmanship
Our gage blocks are manufactured under carefully controlled conditions and inspected by the ASME B89.1.9-2002 standard, allowing for an accuracy of +/- 6 millionth for size under 1" block when used at room temperatures of 68 degrees Fahrenheit (or 20 degrees Celsius). The gage blocks are made of fully seasoned alloy tool steel with hardened to 65 RC to provide resistance to wear, abrasion, and rust. The measuring surface of the gage block are ground and micro-lapped to a mirror finished so the gage block can be wringable. The inspection are conducted in an ISO-9001 certified laboratory with a master block set that is traceable to NIST and each block's deviation are recorded on the NIST traceable calibration form.
Spotlight
-
Mirror Finish
The measuring faces (2 sides) are ground and micro lapped to surface roughness of Ra 0.016 while the non measuring face (4 sides) are maintain at Ra 0.63. The mirror finished surface allow the gage block to be easily wringable. -
Laser Marking
Each gage block is laser marked with nominal length and serial number with reference to the calibration certificate. -
ASME B89.1.9-2002 standard
Inspection are taken place in a ISO-9001 certified laboratory and each block's measurement is recorded on the NIST traceable certificate, not a ISO17025 long form certificate. -
Wooden Insert
Each block is wrapped in a greasproof paper and placed inside the wooden insert holder to prevent corrosion and abrasion.
