Gauge BlocksFeatures and Accuracies

Features of Mitutoyo Gauge BlocksMitutoyo o�ers rectangular steel and ceramic (CERA 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 certi�ed 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).

WringingLapping measuring surfaces is one of Mitutoyo’s specialties. Our advanced technique, developed over more than half a century, enables us to achieve the optimum �atness and surface �nish 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 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.

CERA BlocksCERA blocks are made of a ceramic material with a superior surface �nish, created by Mitutoyo’s ultra-precision machining techniques, that provides a premium quality block with signi�cant advantages:1. Corrosion ResistantAnti-corrosion treatment is not required when handled normally (i.e. with �ngers), resulting in simple maintenance and storage.2. No Burrs Caused by Accidental MishandlingSince the CERA 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 ResistantCERA Blocks have 10 times the abrasion resistance of steel gauge blocks.

4. Dimensionally StableCERA Blocks are free from dimensional change over time.5. Clearly Marked SizesBlack 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 �atness and surface �nish provides maximum wringing force.

Grade and ApplicationGrade 2:These gauge blocks are intended for shop �oor use to set and calibrate �xtures 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 sta�. 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 (speci�ed by DIN861, BS4311, and JIS B 7506).

Constructing a Gauge Block StackThe 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 signi�cant digit �rst, then work back through the more signi�cant 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.

Example: Required length = 45.6785 mm For a 1 mm-based gauge block set (112 pcs.)

1.0005 1.008 1.17 17.5 + ) 25.0 45.6785 mm

For a 2 mm-based gauge block set (112 pcs.) 2.0005 2.008 2.17 14.5 + ) 25.0 45.6785 mmNote: For details on the recommended method of wringing, refer to page E-17.

Mitutoyo Gauge Blocks and Inspection Certi�catesA Certi�cate of Inspection is furnished with all Mitutoyo gauge blocks with a serial number on the box (in the case of sets) and an identi�cation 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.

9. Closest Expansion Coe�cient to SteelThe thermal expansion coe�cient of a CERA Block is quite similar to that of a steel gauge block.

10. Highly Resistant to Impact DamageThe CERA Block material is one of the toughest ceramics. It is extremely di�cult to crack a CERA block in normal use.

Gauge BlocksSERIES 516 – Maintenance Kit for Gauge Blocks

Maintenance kit for gauge blocks includes all the necessary maintenance tools for removing burrs and contamination before use, and applying anti-corrosion treatment after use, etc.

Recommendation for Regular CalibrationGauge blocks are often used to de�ne 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 a�ected 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.

As an accredited calibration laboratory, Mitutoyo o�ers a traceable calibration service for customers’ gauge blocks. Our regular calibration service features:

Gauge blocks manufactured by any maker can be calibrated.

Cleansing and removal of burrs. Central dimension and dimensional deviations of each block

are measured. Calibration results are provided for immediate use and for

building a calibration history of each block.

Removing BurrsFigure 1

Figure 2

(1) Wipe any dust and oil �lms 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 �at. 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 �at 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 o�er Arkansas stones.

� De�nition of the MetreThe 17th General Conference of Weights and Measures in 1983 decided on a new de�nition of the metre 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.

� Selection, Preparation and Assembly of a Gauge Block Stack

Select gauge blocks to be combined to make up the size required for the stack. (1) Take the following things into account when selecting gauge blocks. a. Use the minimum number of blocks whenever possible. b. Select thick gauge blocks whenever possible. c. Select the size from the one that has the least signi�cant digit

required, and then work back through the more signi�cant digits.(2) Clean the gauge blocks with an appropriate cleaning agent.(3) Check the measuring faces for burrs by using an optical �at as

follows:

a. Wipe each measuring face clean. b. Gently place the optical �at on the gauge block measuring face. c. Lightly slide the optical �at until interference fringes appear. Judgement 1: If no interference fringes appear, it is assumed that

there is a large burr or contaminant on the measuring face.

d. Lightly press the optical �at to check that the interference fringes disappear.

Judgement 2: If the interference fringes disappear, no burr exists on the measuring face.

Judgement 3: If some interference fringes remain locally while the �at is gently moved to and fro, a burr exists on the measuring face. If the fringes move along with the optical �at, there is a burr on the optical �at.

e. Remove burrs, if any, from the measuring face using a �at, �ne- grained abrasive stone.

(4) Apply a very small amount of oil to the measuring face and spread it evenly across the face. (Wipe the face until the oil �lm is almost removed.) Grease, spindle oil, vaseline, etc., are commonly used.

(5) Gently overlay the faces of the gauge blocks to be wrung together. There are three methods to use (a, b and c as shown below)

according to the size of blocks being wrung:

Gauge BlocksQuick Guide to Precision Measuring Instruments

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 90º 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, �rst 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 �rst thin gauge block.

Apply an optical �at 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.

SERIES 517 – Black Granite Surface Plates

Natural granite is free from deterioration or dimensional change over time.

Granite surface plates have signi�cant 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 �ne grain structure and insigni�cant stickiness; this ensures a high degree of �atness 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 �atness error occurs when there is a temperature di�erence 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%)
