3 Gauge Blocks Features and Accuracies Features of Mitutoyo Gauge Blocks Mitutoyo offers rectangular steel and ceramic (CRA Blocks) gauge blocks for use as length standards in variously sized sets and as individual blocks. Accessories include wear blocks in tungsten carbide and ceramic in the standard thicknesses. Mitutoyo gauge blocks are recognized to be of the highest quality and are available in various grades to meet every need in respect of working conditions, environment and application. Accuracy As a world-leading precision measuring equipment manufacturer, Mitutoyo is certified by the Japanese government as an accredited calibration laboratory, which means that the accuracy of its gauge blocks is guaranteed through traceability to the Metrology Management Centre of the National Institute of Advanced Industrial Science and Technology (AIST). Wringing Lapping measuring surfaces is one of Mitutoyo s specialties. Our advanced technique, developed over more than half a century, enables us to achieve the optimum flatness and surface finish needed for gauge blocks and thus maximize the wringing force. 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 temperature cycling, simultaneously achieves excellent abrasion resistance and minimizes any change in length over time. CRA Blocks CRA blocks are made of a ceramic material with a superior surface finish, created by Mitutoyo s ultraprecision machining techniques, that provides a premium quality block with significant advantages: 1. 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 Accidental Mishandling Since the CRA Block is very hard, it will not scratch easily 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 10 times the abrasion resistance of steel gauge blocks. Abrasion loss (µm) Abrasion loss data Dimensionally Stable CRA Blocks are free from dimensional change over time. 5. Clearly Marked Sizes Black 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 Contamination Steel Silicon nitride Tungsten carbide CRA Block Sliding distance (m) 7. High Wringing Force Superior flatness and surface finish provides maximum wringing force. Grade and Application 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 inspection staff. Mainly used as reference standards for setting high precision measuring equipment and for the calibration of lower grade gauge blocks. The following table can be used to select the gauge block grade according to usage (specified by DIN861, BS4311, and JIS B 7506). Usage Applications Grade Mounting tools and cutters 2 Workshop Manufacturing gauges use 1 or 2 Calibrating instruments Inspection use Calibration use Inspecting mechanical parts, tools, etc. Checking the accuracy of gauges Calibrating instruments Checking the accuracy of gauge blocks for workshop Checking the accuracy of gauge blocks for inspection Checking the accuracy of instruments 1 or 2 0 or 1 Constructing a Gauge Block Stack The following points should be noted when constructing a gauge block stack: 1. 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 reduce wear as much as possible, do not always use the same gauge blocks. xample: Required length = mm Using an 88-block metric set mm xample: Required length = " Using an 81-block inch set " 0-03

4 Mitutoyo Gauge Blocks and Inspection Certificates A Certificate of Inspection is furnished with all Mitutoyo gauge blocks with a serial number on the box (in the case of sets) and an identification number on each block. The deviation of each block from nominal length, at the time of inspection, is stated. For this inspection, each gauge block is measured relative to the upper level master using a gauge block comparator. 8. Characteristics of CRA Blocks Compared with other Gauge Block Materials Property CRA Block (ZrO2) Steel (Fe) Material Tungsten Carbide (WC-Co) Silicon nitride (Si3N4) Hardness (HV) Coefficient of thermal expansion (10-6 /K) 9.3± ± ±1.0 2 Flexural strength by 3-point bending (MPa) Fracture toughness K1c (MPa m 1/2 ) Young s modulus x10-4 (MPa) Poisson s ratio Specific gravity Thermal conductivity (W/m k) Note: Ceramics have the advantage of a slow response to temperature changes due to the low thermal conductivity. However, caution is required when using CRA blocks in an environment subject to rapid temperature change. 9.

Gloves (600009): For handling large blocks to prevent expansion due to heat transfer from operator Recommendation for regular calibration Gauge blocks are often used to define a company s standard of length for manufacturing and as such must be reliable. This means that they need regular calibration to verify accuracy. (The problem of damage or corrosion should be addressed during use and blocks seriously affected must be discarded immediately.) The frequency of calibration depends on the tolerance requirements of the work, the amount of use and conditions under which the gauge blocks are used. The most economical cycle for any particular set of gauge blocks is best determined by studying the calibration history. The list below indicates timings for a typical initial calibration cycle for the various grades of block. Application Cycle Grade Reference 1-2 years K Calibration 2 years K or 0 Inspection 2 years 0 or 1 Shop floor year 1 or 2 As an accredited calibration laboratory, Mitutoyo offers a traceable calibration service for customers gauge blocks.

16 Removing burrs Ceraston Accessory for Gauge Block Maintenance Figure 1 CRASTON (Or Arkansas stone) Alumina-ceramic abrasive stone for removing burrs from hard materials such as ceramics that ordinary stones cannot handle. Can be used both for steel gauge blocks and CRA blocks. xcellent in the ease with which burrs can be removed and for durability compared with Arkansas stones. Both sides can be used. Figure 2 Rubber CRASTON (Or Arkansas stone) 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 to prevent the surface of the gauge block from being scratched. Mitutoyo does not offer Arkansas stones Code No. Dimensions (W x D x H) Price x 50 x 20 mm x 25 x 12 mm Application example. -16

32 Technical Data Grade: Conforms to BS Optional Accessory Code No. Description Price CM0700 Granite cleaner (1 l) SRIS 517 Black Granite Surface Plates Natural granite is free from deterioration or dimensional change over time. Granite surface plates have significant advantages over cast iron surface plates: twice as hard as cast iron; non-magnetic; low thermal expansion. 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 workpieces or instruments. Free from wringing, so there is no interruption of work. Use these plates in a stable temperature environment. Since flatness error occurs when there is a temperature difference between the working surface and the underside, avoid working in direct sunlight. Also, do not place a plate in the vicinity of an air conditioner, etc. (Recommended environment: temperature 20±1 C, humidity 58±2%.)
