2 Gage Block SERIES 56 Precision gage blocks are the primary standards vital to dimensional quality control in the manufacture of parts. Mitutoyo offers a complete selection of gage blocks available in a choice of rectangular or square, metric or inch and steel or CERA (ceramic) types. Accuracy Mitutoyo gage blocks guarantee such a high accuracy that users can use them without anxiety. Mitutoyo has established a traceability system for our measurement 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. Selecting Gage Blocks Select gage blocks in accordance with the combination range required. If a large length is required, add a long block set. Select gage blocks in accordance with the minimum length step required. Add wear block sets if necessary. If a set containing a large number of gage blocks is selected, the number of combination gage blocks required for a length is reduced and the number of combinations is increased. The accuracy will be retained and damage will be reduced. The specific gage block set for micrometer inspection and caliper inspection is available. If using only one length repeatedly, it is a good idea to purchase discrete gage blocks. The 2mm-based gage blocks, which take the base of the minimum length step as 2mm, are easy to handle and will not warp, as compared to the mm-based gage blocks. Wringing The lapping technique is one of Mitutoyo s specialties. Our advanced lapping technique, developed for more than a half century, allows us to achieve the best flatness and surface roughness needed for gage blocks. Abrasion Resistance and Dimensional Stability High-carbon, high-chrome steel is employed to sufficiently satisfy a variety of material characteristics required for gage blocks. A high degree of hardness, obtained by our heat treatment technology, as well as methodically repeated heat treatment, have successfully reduced deterioration change over time. CERA Blocks CERA blocks, made of ceramic materials with superior surface quality, were developed by Mitutoyo s ultra-precision machining techniques and solve problems commonly associated with steel gage blocks. Rectangular Block Gage Size Face Width (A) Face Depth (B) Up to Over.2 up to Up to mm 3mm mm Over mm up to mm 35mm mm. Corrosion-Resistant Anti-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 (m) ceramic deburring stone (Ceraston). 3. Abrasion Resistant.4 CERA Blocks have times the abrasion resistance of steel gage blocks Dimensional Stability CERA Blocks are free from dimensional change over time. 5. Marking The black characters, indicating the nominal length, are inscribed by laser and are clearly visible against the white surface of the block.

3 Grade and Application Refer to the following table to select the gage block grade according to usage. Applications Grade Workshop use Mounting tools and cutters AS- or AS-2 Manufacturing gages or AS- Calibrating instruments Inspection use Inspecting mechanical parts, or AS- tools, etc. Checking the accuracy of gages or Calibrating instruments Calibration use Checking the accuracy of gage K or blocks for workshop Checking the accuracy of gage blocks for inspection Checking the accuracy of instruments Reference use Checking the accuracy of gage blocks for calibration For academic research K Grade AS-: These gage blocks are intended for shop-floor use to set and calibrate fixtures, as well as precision instruments. Grade : This grade is used within an inspection area to verify the accuracy of plug and snap gages, as well as for setting electronic measuring devices. Grade : These higher accuracy gages are intended for use within a controlled environment by skilled inspection staff. Mainly used as reference standards for setting high-precision measuring equipment and for the calibration of lower grade gage blocks. Grade K: Gage 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 gage blocks which are calibrated by comparison. Combination of a Required Length Multiple combinations of gage blocks can be used to make a required length. Care should be exercised in the following points.. Use as few gage blocks as possible to obtain the required length. (Select thick gage blocks whenever possible.) 2. Select gage blocks starting with the one that has the least significant digit required, and then work up to ones with more significant digits. 3. There are multiple combinations for the integer part of a length. To prevent wear as much as possible, do not always use the same gage blocks. Example combination Required length = mm For the mm-based gage block set (2 pcs.) mm For the 2mm-based gage block set (2 pcs.) mm 6. Anti-magnetic Nature Keeps Away Steel Powders 7. High Wringing Force An even, dense tissue can maintain a strong wringing force. 8. Material of CERA block Material CERA Block Steel Carbide Silicon nitride Property (ZrO 2) (Fe) (WC-Co) (Si 3N 4) Hardness (HV) Coefficient of thermal expansion ( -6 /K).3±.5.8±.5 5.5±. 2 Flexural strength by 3-point bending (MPa) Fracture toughness Kc (MPa m /2 ) Young s Modulus x4 (MPa) Poisson s Ratio Specific gravity Thermal conductivity (W/m k) Closest Expansion Coefficient to Steel The thermal expansion coefficient of a CERA Block is similar to that of a steel gage block.. Highly Resistant Against Drops and Other Shocks The CERA block material is one of the toughest ceramics materials. It is extremely difficult to crack under normal use. Features of Square Gage Blocks. Perfect wringing is possible using the center hole. After wringing the square gage blocks, an optional tie rod can be inserted through the center hole to fix the blocks using a screw. 2. A height reference standard can easily be made. A precision height reference standard can be made easily and inexpensively using accessories such as the plain jaw and block base. 3. A dedicated inspection jig can be easily made. A dedicated inspection jig for periodic inspection of instruments can be made easily and inexpensively. 4. A wide measuring surface with cross section dimensions of [24. x 24.mm /.5 x.5 ] is available. A square gage block can retain stable orientation both longitudinally and laterally. A wide range of application measurements can be made, including cutting tool positioning, angle measurement with a sine bar, taper measurement with a roller, and inspection of depth micrometers. Long and Ultra-Thin Gage Blocks Mitutoyo offers extra thin gage blocks from. mm to. mm (increments of. mm), as well as long gage blocks up to, mm as standard products. 7 Difference in dimension (m) 3 Silicon nitride 8 2 Tungsten carbide CERA Block Temperature (C) Differences in the dimension between some materials and steel that are obtained when measuring testpieces with a length of mm at each temperature.

41 Radius Gages-Sets SERIES 86 Radius Gages are recommended for checking or laying out concave or convex radii. An individual gage for each dimension makes it possible to verify radius or fillet dimensions easier, faster and more accurately in machining, layout, inspection and patternmaking work. The measuring surfaces are precisely finished with smooth, accurate edges. Radius gages are available separately or in six sets. Each radius gage has five measuring locations, and it is identified with its particular radius dimensions. The gages have a satin or dull-chrome finish. The holding cases, provided to protect the sets of radius gages, have indexed pockets to facilitate the selection of the proper size gage. A 4 long holder is furnished with Set No. 86- to make it possible to check radii in confined or hard-to-reach locations. Accuracy: ±.6" /.4mm concave and convex radii per leaf.

45 Black Granite Surface Plate SERIES 57 Cast iron surface plate Granite surface plate Natural granite seasoned for thousands of years is free from deterioration or dimensional change over time. Granite surface plate has many advantages over cast iron surface plates: Twice as hard as cast iron. Minimal changes in dimension due to temperature changes. Free from wringing, so there is no interruption of work. Free from burrs or protrusions because of the fine grain structure and insignificant stickiness; this ensures a high degree of flatness over a long service life and causes no damage to other parts or instruments. Trouble-free operation for use with magnetic materials. Long life and rust-free, resulting in low maintenance costs. Mitutoyo granite surface plates meet or exceed federal specification GGG-P- 463c. Each surface plate is shipped with a Certificate of Accuracy which guarantees its accuracy and verifies its traceability to NIST. All plates from 48 x8 and larger are machine base gray granite. Smaller plates are black granite. Surface plates, to size of specifications other than standard, available by special order. Surface plates, with the bolt screws, available by special order.
