2 Gauge Blocks SRIS 56 FATURS Precision gauge blocks are the primary standards vital to dimensional quality control in the manufacture 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 Gauge blocks offered by Mitutoyo, an all-round precision measuring machine manufacturer, 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 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. 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. If using only one length repeatedly, it is a good idea to purchase discrete gauge blocks. The 2mm-based gauge blocks, which take the minimum length step as 2mm, are easier to handle than mm-based gauge blocks. Abrasion Resistance and Dimensional Stability of Steel blocks High-carbon high-chrome steel is employed to satisfy a variety of the material characteristics required 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. CRA Blocks CRA 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.. 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 CRA 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 Resistant CRA Blocks have 0 times the abrasion resistance of steel gauge blocks.. Dimensionally Stable CRA Blocks are free from dimensional change over time. 5. Sizes Clearly Marked 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 The following table can be used to select the gauge block grade according to usage (specified by DIN86, BS3, and JIS B 7506). Applications Grade Workshop use Mounting tools and cutters 2 Manufacturing gages or 2 Calibrating instruments use Inspecting mechanical parts, or 2 tools, etc. Checking the accuracy of gages Calibrating instruments 0 or Calibration use Checking the accuracy of gauge K or 0 blocks for workshop Checking the accuracy of gauge blocks for inspection Checking the accuracy of instruments Reference use Checking the accuracy of gauge K blocks for calibration For academic research Grade 2: These gauge 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 0: These higher accuracy gauges 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 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. Constructing a Gauge Block Stack The following points should be noted when constructing a gauge block stack:. Use as few gauge blocks as possible to obtain the required length by selecting thick blocks wherever possible. 2. Select the block for the least significant digit first, then work back through the more significant digits until the required length is attained. 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 gauge blocks. xample: Required length = mm For the mm-based gauge block set (2 pcs.) mm For a 2mm-based gauge block set (2 pcs.) mm 6. Non-magnetic Nature Prevents Steel Swarf Contamination 7. High Wringing Force Superior flatness and surface finish provides maximum wringing force. 8.

Highly Resistant to Dropping and Impact The CRA Block material is one of the toughest ceramics. It is extremely difficult to crack a CRA block in normal use. 7 Difference in dimension (µm) Features of Square Gauge Blocks. Stack can be positively clamped by using the center hole After wringing square gauge blocks, an optional tie rod can be inserted through the center hole to clamp the blocks together 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 easily be made A dedicated inspection jig for periodic inspection of instruments can be made easily and inexpensively.. A wide measuring surface with crosssectional dimensions of 2. x 2.mm is available. A square gauge block retains stable orientation both longitudinally and laterally. A wide range of application are covered, including cutting tool positioning, angle measurement with a sine bar, taper measurement with a roller, and inspection of depth micrometers. Long and Ultra-Thin Gauge Blocks Mitutoyo offers extra-thin gauge blocks from 0.0 mm to 0. mm (increments of 0.0 mm) as well as long gauge blocks up to,000 mm as standard products. 8 3 Silicon nitride 2 Tungsten carbide CRA Block Temperature (C) Differences in the dimension between some materials and steel that are obtained when measuring testpieces with a length of 00mm at each temperature. -3

(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. ). 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. Maintenance Kit for Gauge Blocks SRIS 56 FATURS Includes all necessary maintenance tools for daily care and storage of gauge blocks. Supplied in a fitted wooden case for portable use. CRASTON (Arkansas stone) Rubber CRASTON (Arkansas stone) Note: The abrasive surface of a Ceraston must be made flat by lapping it from time to time.

26 GBI (Interference fringe analyzing processing) Automatic Gauge Block Calibration FATURS GBI is an instrument for calibrating the length of rectangular gauge blocks and square gauge blocks having a length up to 250 mm by using optical interference. GBI is a Twyman-Green Interferometer, and by referring to the value having been measured by the gauge block comparator in advance, GBI calibrates the length more accurately according to the coincidence method using two wavelengths. GBI uses a CCD camera to automatically record the distribution and intensity of the interference fringes formed on the block surface under test. This data is then processed using the phase shifting method and the interference fringe analyzing software to determine not only the length of the block but also its parallelism and flatness. Since the measurement is performed within an enclosed measurement booth, calibration with extremely high stability can be achieved. GBI uses two stabilized He-Ne lasers, which have highly stable light intensity and wavelength and are traceable to the national length standard. The refractive index of air and the thermal expansion of the gauge block to be measured are automatically compensated by the PC, to which temperature sensors, a hygrometer and a barometer are connected.
