Gauge Blocks
Series 516
Precision gauge blocks are the primary standards vital to dimensional quality control in the manu-
facture of parts. Mitutoyo offers an extensive selection of gauge blocks available in a choice of
rectangular or square, metric or inch, and steel or ceramic types.
Accuracy CERA Blocks
Gauge blocks offered by Mitutoyo guarantee such a high accuracy that users can use them com-
plete confidence. Needless to say, Mitutoyo has established a traceability system for our measure-
ment products, up to the Metrology Management Center of the National Institute of Advanced
Industrial Science and Technology (AIST) and we have been certified by the Japanese government
as an accredited laboratory.
Wringing
The lapping technique is one of Mitutoyo’s specialties. Our advanced technique, developed over
more than a half century, enables us to achieve the best flatness and surface roughness needed for
gauge blocks and thus maximize the wringing force.
Abrasion Resistance and Dimensional Stability of Steel blocks CERA Blocks - Abrasion Resistant
High-carbon high-chrome steel is employed to satisfy a variety of the material characteristics re-
quired for gauge blocks. Our advanced heat treatment technology for steel blocks, which involves
repeated high and low temperature cycles, simultaneously achieves excellent abrasion resistance
and reduces change in length over time to the minimum.
CERA Blocks CERA Blocks - Non magnetic
CERA blocks are made of a ceramic material with a superior surface finish, created by Mitutoyo’s
ultra-precision machining techniques, that provides a premium quality block. Selecting Gauge Blocks
