Gage BlockSelecting Gage BlocksSERIES 516FEATURESPrecision gage blocks are the primarystandards vital to dimensional quality controlin the manufacture of parts. Mitutoyo offersa complete selection of gage blocks availablein a choice of rectangular or square, metricor inch and steel or CERA (ceramic) types.AccuracyGage blocks offered by an all-round precision measuring machine manufacturer, Mitutoyo,guarantee such a high accuracy that users can use them without anxiety. Needless to say,Mitutoyo has established a traceability system for our measurement products, up to theMetrology Management Center of the National Institute of Advanced Industrial Science andTechnology (AIST) and we have been certified by the Japanese government as an accreditedlaboratory. Select gage blocks in accordance with the combinationrange required. If a large length is required, add a longblock set. Select gage blocks in accordance with the minimum lengthstep required. Add wear block sets if necessary. If a set containing a large number of gage blocks isselected, the number of combination gage blocks requiredfor a length is reduced and the number of combinations isincreased. The accuracy will be retained and damage willbe reduced. The specific gage block set for micrometer inspection andcaliper inspection is available. If using only one length repeatedly, it is a good idea topurchase discrete gage blocks. The 2mm-based gage blocks, which take the base of theminimum length step as 2mm, are easy to handle and willnot warp, as compared to the 1mm-based gage blocks.WringingThe lapping technique is one of Mitutoyo’s specialties. Our advanced lapping technique,developed for more than a half century, enables us to achieve the best flatness and surfaceroughness needed for gage blocks and realize a great wringing force.Abrasion Resistance and Dimensional StabilityHigh-carbon high-chrome steel is employed to sufficiently satisfy a variety of materialcharacteristics required for gage blocks. A high degree of hardness, obtained by our heattreatment technology and that reassures users, as well as methodically repeated heattreatment, have successfully reduced deterioration change over time to the minimum.CERA BlocksRectangular BlockGage SizeUp to 2”Over .2” up to 40”Up to 10mmOver 10mm up to1000mmFace Width (A)1.181”1.378”30mm35mmFace Depth (B).355”.355”9mm9mmGage SizeFace Width (C)Inch (up to 40”).95”Metric (up to 1000mm) 24.1mmFace Depth (D).95”24.1mmCERA blocks, made of ceramic materials withsuperior surface quality, that were developed byMitutoyo’s ultra precision machining techniquessolve all problems that the steel gage block had.Square BlockAbrasion loss1. Corrosion-ResistantAnti-corrosion treatment is not required whenhandled normally (i.e. with fingers), resultingin simple maintenance and storage.2. No Burrs Caused by Dents, etc.Since the CERA Block is very hard, it will notscratch and is highly resistant to burrs. If aburr is formed, it can easily be removed with aceramic deburring stone (Ceraston).(m)Resistance to wear3.

Grade and ApplicationRefer to the following table to select the gage block gradeaccording to usage.ApplicationsWorkshop use Mounting tools and cutters Manufacturing gages Calibrating instrumentsInspection use Inspecting mechanical parts,tools, etc. Checking the accuracy of gages Calibrating instrumentsCalibration use Checking the accuracy of gageblocks for workshop Checking the accuracy of gageblocks for inspection Checking the accuracy ofinstrumentsReference use Checking the accuracy of gageblocks for calibration For academic researchGradeAS-1 orAS-20 or AS-10 or AS-100 or 0K or 00KGrade AS-1:These gage blocks are intended for shop floor useto set and calibrate fixtures as well as precisioninstruments.Grade 0:This grade is used within an inspection area to verifythe accuracy of plug and snap gages as well as forsetting electronic measuring devices.Grade 00:These higher accuracy gages are intended for usewithin a controlled environment by skilled inspectionstaff. Mainly used as reference standards for settinghigh precision measuring equipment and for thecalibration of lower grade gage blocks.Grade K:Gage blocks of this accuracy are intended for usewithin a temperature controlled inspection room orcalibration laboratory. They should be used as masterswith certificates against other gage blocks which arecalibrated by comparison.Combination of a Required LengthMultiple combinations of gage blocks can be used to make arequired length. Care should be exercised in the followingpoints.1. Use as few gage blocks as possible to obtain the requiredlength. ( Select thick gage blocks whenever possible.)2. Select gage blocks starting with the one that has leastsignificant digit required, and then work up to ones withmore significant digits.3. There are multiple combinations for the integer part ofa length. To prevent wear as much as possible, do notalways use the same gage blocks.Example combinationRequired length 45.6785mmFor the 1mm-based gage block set (112 pcs.)1.00051.0081.1717.5 2545.6785mmFor the 2mm-based gage block set (112 pcs.)2.00052.0082.1714.5 2545.6785mm6.
