Bore Gages• This equipment is used to calibrate gauge blocks with a nominal
size from 0.5 mm to 100 mm, by performing incremental
measurement against a reference gauge block.
Set the gauge block to calibrate with the reference gauge
block set to the holder and start calibration. Measurement is
automatically performed in the center and at 5 measurement
points on the edges.
• The compensation result is not affected by any warping of
thinner gauge blocks due to the use of upper and lower gage
heads (dual-head system).
• Gauge Block Inspection Software GBPAK-AJ can be used tooperate inspection equipment, determine grades, and prepare
inspection results. It can also output text data in TSV format, for
editing using Excel or other spreadsheet software.

Standard Configuration5• This equipment is used to calibrate gauge blocks with a nominal
size from 0.1 mm to 250 mm, by performing incremental
measurement against a reference gauge block.
• Calculation uses two vertically arranged detectors (dual head)to ensure that results are not affected by any thin gauge block
warping.
• An ultra-wide-range and high-accuracy sensor (linear gauge:
measurement range 6 mm, effective display amount 0.01 μm) isused to dramatically reduce the amount of troublesome minuteheight adjustment work for detectors. It can also calibrate gauge
blocks of different nominal dimensions against a single reference
gauge block. (Accuracy will vary when measuring combinationsof different nominal dimensions. Refer to the specifications
section for accuracy.)• A PC and Gauge Block Inspection Software GBPAK-ME canbe optionally used to load data, determine grades, and prepare
inspection results. It also outputs text data in TSV format, for
editing using Excel or other spreadsheet software.

Hs 32 to 40• Excellent corrosion resistanceExcellent corrosion resistance compared with cast iron, with norusting and little reduction in weight caused even by acid.
• Resistant to ringing
Ringing can occur in cast iron surface plates, which caninterrupt work. Black Granite Surface Plate is normally resistant
to ringing, making work smoother.
• No burring even if scratched• If the upper surface of a cast iron surface plate is scratched, burringor bulging may occur as the material of the plate is viscous, which
will reduce flatness. This will reduce measurement accuracy and could
even cause damage to the object being measured or the measuring
instrument.
• Black Granite Surface Plate has a fine-grained hard structure that isless viscous than cast iron, and does not suffer from burring or bulging.
This ensures that flatness remains constant and that instruments are
not damaged.

Cast iron surface plate

Granite surface plate• Non-magnetic
Black Granite Surface Plate is non-magnetic, and can easily be
used even with magnetic instruments.
• Inexpensive maintenanceBlack Granite Surface Plate does not rust and has a long service
life, resulting in much lower maintenance costs compared witha cast iron surface plate.

• Hardly any age-based deterioration
Black Granite Surface Plate makes use of gabbro, a natural rockwith a highly uniform structure that has undergone natural
seasoning for several thousands of years, resulting in hardly
any age-based deterioration. In comparison, a cast iron surface
plate will always be susceptible to age-based deteriorationeven though heat treatment technologies have undergone
remarkable improvements.
• Excellent abrasion resistanceWith more than twice the hardness of cast iron, the greatest
benefit of a Black Granite Surface Plate is its excellent abrasion
resistance. (Reference: Shore hardness)

• Placing or moving an object on a stone surface plate with dust
or dirt adhered may cause the surface to be scratched or worn,
which may affect the accuracy. Be sure to wipe any dust or dirt
off well before use.

Rigidity of the surface plate
JIS B 7513· 1992 stipulates the rigidity of the precision surface plate as follows.
"The rigidity must be such that when a load is applied to the center of the usedsurface, the deflection of where the load is applied must not exceed 1 μm per 200 N."
The deflection is calculated by the following formula, which demonstrates that theBlack Granite Surface Plate fully satisfies this standard value. (Ex. For plates measured
1500 × 1000 × 200 mm, the deflection is 0.09 μm)
y=

Critical strength
As with the main dimensional drawing, the maximum allowable load (Wmax ) that canbe applied to the center of the surface plate when supported by three support points
a, b and c and two auxiliary points d and e can be calculated by the following formula.
(Ex. For 1500 × 1000 × 200 mm, the critical strength is 32000 N)

The flatness measurement error that occurs when there is a difference in temperature
between the used surface and back surface can easily be determined using thefollowing equation. Note that this is only a reference value as it may differ from theactual result. (Ex.: The flatness measurement error would be 2.2 μm for 1500 × 1000

Black Granite Surface Plate has a precise reference plane. Notethat the original accuracy may not be maintained if it is improperly
installed. It is necessary to pay attention to the following points.

Installation location• A location with little temperature changes
If large temperature changes occur in the installed environment,
there will be a temperature difference between the used surface
and back surface, resulting in a flatness measurement error.
Avoid installing the Black Granite Surface Plate in a place where
temperature changes may occur, such as where there is direct
exposure to sunlight or near an air conditioner. Be sure to use it ina stable environment where the temperature difference does notoccur as much as possible.

Support point and installation stand• For the Black Granite Surface Plate, support legs are attached tothree points with the least deflection. For the large Black Granite
Surface Plate, it may be necessary to provide multi-point support.
• Stands made of steel, cast iron and other materials are available,
such as an integrated type for small to medium Black Granite
Surface Plates and a block stand (tripod type) for large Black
Granite Surface Plates.

Surface Plate
Main support(3 required)

Auxiliary support(2 or 3 required)*Recommended environment: Temperature 20±1°C, humidity 58±2%,temperature difference between the front and back surfaces within 0.2°C• Location without vibration
On the surface plate, measurement is often made using a
detector such as a test indicator (lever type dial gauge) or
Mu-checker (electric micrometer), so it is necessary to choose alocation where there is no vibration so as to prevent the pointerfrom deviating and becoming difficult to read.
• Location with small particles and dust
Black Granite Surface Plates are widely used not only in precision
measurement rooms but also in work sites. Be sure to avoid
locations that are affected by small particles, abrasive powder or
locations with a large amount of dust.

Installation height of the used surface
The height of the used surface affects the working efficiency, so itneeds to be determined in advance according to the work. Generally,
the height of the used surface should be around 750 mm.

Offering high-level services globally based on
measurement capabilities of the same level as
national standards
Traceability system

Mitutoyo ensures and maintains traceability of various types of precision measuring machines by holding length standards (the optical frequency
comb*1), etc., directly traceable to the national standards for use in calibrating the working standards used for the calibration of measuring instrument
products supplied to industry. Regarding the calibration service using the optical frequency comb as the standard, this provides performanceequivalent to that of Japan’s National Length Standard and for which we have obtained accreditation by the Japan Calibration Service System (JCSS)*2.
Mitutoyo calibration centers have gained JCSS accreditation from IAJapan*3, the accreditation organization internationally recognized by the
MRA*4 of ILAC*5, and the measuring technology capabilities of these centers are therefore recognized as equivalent to those of overseas calibration
organizations. In addition, our calibration centers is also be available as an external laboratory specified by various quality management systems (IATF
16949 standard, etc.) when customers are outsourcing their calibration service.
Since Mitutoyo has achieved the highest level of traceability for our measurement instruments both in Japan and overseas, customers can use our
products with absolute confidence.
