Gauge Blocks Overview
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.
AccuracyGauge 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.
WringingThe 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 blocksHigh-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 BlocksCERA 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. 1. Corrosion ResistantAnti-corrosion treatment is not required when handled normally (i.e. with fingers), resulting in simple maintenance and storage.2. No Burrs Caused by Dents, etc.Since the CERA Block is very hard, it will not scratch and is highly resistant to burrs. If a burr is formed, it can easily be removed with a ceramic deburring stone (Ceraston).3. Abrasion ResistantCERA Blocks have 10 times the abrasion resistance of steel gauge blocks.4. Dimensionally StableCERA Blocks are free from dimensional change over time.5. Sizes Clearly MarkedBlack characters, indicating the nominal length, are inscribed by laser and are clearly visible against the white surface of the block.6. Non-magnetic Nature Prevents Steel Swarf Contamination7. High Wringing ForceSuperior flatness and surface finish8. Superior Material Characteristics of CERA Block

Selecting Gauge Blocks• Gauge blocks are designed to offer the construction
of practically any size, within the range of a set, using the minimum number of blocks. Long block sets are available if a longer length is required than is provided by the standard sets.
• Gauge block sets should be selected in accordance with the minimum length step required. Wear block sets should be used if the application is likely to involve rapid wear of the end blocks in a stack (and the minimum sizes required allow this). This will preserve the life of the set by confining wear to the wear blocks, whose cost of replacement is far less than that of a complete set.
• If a set containing a large number of gauge blocks is selected, the number of gauge blocks required for any particular length may be reduced and the number of combinations is increased. Accuracy will be retained and wear will be reduced.
• Dedicated gauge block sets for micrometer inspection and caliper inspection are available.

Gauge Blocks Overview
Differences in the dimension between some materials and steel that are obtained when
measuring testpieces with a length of 100 mm at each temperature.
Series 516
9. Closest Expansion Coefficient to SteelThe thermal expansion coefficient of a CERA Block is quite similar to that of a steel gauge block.10. Highly Resistant to Dropping and ImpactThe CERA Block material is one of the toughest ceramics. It is extremely difficult to crack a CERA block in normal use.
Grade and ApplicationThe following information can be used to select the gauge block grade according to usage (speci-fied by DIN861, BS4311, JIS B 7506 and EN ISO 3650).Grade 2:These gauge blocks are intended for shop floor use to set and calibrate fixtures as well as precision instruments.Grade 1:This grade is used within an inspection area to verify the accuracy of plug and snap gauges as well as for setting electronic measuring devices.Grade 0:These higher accuracy gauges are intended for use within a controlled environment by skilled in-spection staff. Mainly used as reference standards for setting high precision measuring equipment and for the calibration of lower grade gauge blocks.Grade K:Gauge blocks of this accuracy are intended for use within a temperature controlled inspection room or calibration laboratory. They should be used as masters with certificates against other gauge blocks which are calibrated by comparison.
CertificatesILACThe International Laboratory Accrediation Cooperation is an international cooperation of laborato-ry and inspection accrediation bodies. The member bodies signed the ILAC MMutual Recognition Arrangement (MRA) which guarantees a cross approval of certificates from accredited laboratories from other countries. The Signatories to the ILAC arrangement are almost all European countries.
JCSSMitutoyo Gauge Block Sets can be delivered with a JCSS Certificate of Calibration (Japan Calibra-tion Service System). A JCSS Certificate of Calibration is comparable with e.g. DAkks, COFRAC, RvA or UKAS Certificate of Calibration. Refer to ILAC this calibration result may be accepted interna-tionally.

Removing burrs
1 Wipe any dust and oil films from the gauge block and the Ceraston (or Arkansas stone) using a solvent.2 Place the gauge block on the Ceraston so that the measuring face that has burrs is on the abrasive surface of the stone. While applying light pressure, move the gauge block to and fro about ten times (Fig. 1). Use a block rubber for thin gauge blocks to apply even pressure (Fig. 2).3 Check the measuring face for burrs with an optical flat. If the burrs have not been removed, repeat step 2. If burrs are too large, they may not be removed with an abrasive stone. If so, discard the gauge block.
Note: The abrasive surface of a Ceraston must be made flat by lapping it from time to time. After lapping the ceraston, the lapping powder must be completely removed from the surface of the stone to prevent the gauge block from being scratched.Mitutoyo does not offer Arkansas stones.

■ Definition of the MeterThe 17th General Conference of Weights and Measures in 1983 decided on a new definition of the meter unit as the length of the path traveled by light in a vacuum during a time interval of 1/299 792 458 of a second. The gauge block is the practical realization of this unit and as such is used widely throughout industry.
■ Perfect wringing of gauge blocks• Wringing should always be performed in a clean place on a soft pad - if gauge blocks slip from your hand, they will not be damaged.
• Wipe off the oil film from the gauge blocks using a soft cloth and petroleum ether.
• After this “rough” cleaning the surfaces are cleaned with a cosmetic brush rinsed with petroleum ether and then “blown free” with an air blower.
• Never use alcohol or common benzine for cleaning; common benzine contains too many impurities and alcohol always has aqueous components which may cause corrosion.
• Best-suited for wiping gauge blocks are microfiber cloths.
• Check the cleaned gauge blocks for rust and scratches.
• If there are any burrs on the measuring surface remove them carefully using a special ceraston for gauge blocks. Move the dry gauge block over the ceraston exerting very low pressure.
• In case the measuring surfaces are in good condition, but wringing is still difficult, you may wipe them with medical cotton wool - its oily components will provide a fine film thus improving the grip of the measuring surfaces

a. Wringing thick gauge blocks
b.Wringing a thick gauge block to a thin gauge block
c.Wringing thin gauge blocks
Cross the gauge blocks at 90˚ in the middle of the measuring faces.
Overlap one side of a thin gauge block on one side of a thick gauge block.
To prevent thin gauge blocks from bending, first wring a thin gauge block onto a thick gauge block.
Rotate the gauge blocks while applying slight force to them. You will get a sense of wringing by sliding the blocks.
Slide the thin gauge block while pressing the entire overlapped area to align the measuring faces with each other.
Then, wring the other thin gauge block onto the first thin gauge block.
Apply an optical flat to the surface of one thin gauge block to check the wringing state.
Wipe the exposed measuring face(s) and continue building up the stack, in the same manner as above, until complete.
Finally, remove the thick gauge block from the stack.
