Standard measuring tools such as micrometers or calipers are commonly used "tools" for measuring flat and parallel features or inner/outer diameters of workpieces. However, when measuring workpieces with complex shapes, such as curved surfaces or narrow grooves, it may be difficult for standard universal measuring tools to reach the accurate measurement position. It is relatively easier and more economical to choose dedicated non-standard measuring tools.

01
Measurement of pipe wall thickness
picture
The picture suggests using a wall thickness micrometer:
picture
picture
Reason: The cylindrical anvil can penetrate deep into the pipe for wall thickness measurement.
The picture suggests using a pipe wall thickness caliper:
Image] [image
Reason: The measuring claw of the main ruler is cylindrical, which can accurately measure the thickness of the pipe wall.
It is recommended to use the pipe thickness table for the picture:
picture
Reason: The measuring anvil is at a 90° angle and can measure the thickness of pipe wall or bent plate.
02
Measurement of pipe inner diameter
picture
The picture suggests using an inner diameter caliper:
picture
picture
Reason: The measuring claw is a blade type and is used to measure inner positions that are difficult to measure. Measuring claws of the same series also include pointed claw type and inner groove type.
The picture suggests using a caliper-type inner diameter micrometer:
picture
picture
Reason: The caliper-shaped measuring surface enables inner diameter measurements that cannot be achieved with a general-purpose micrometer.
It is recommended to use the inner diameter table for the picture:
picture
Reason: It can measure the diameter of the bottom surface of the inner hole, and the inner diameter of the deep hole can be measured by connecting the extension rod.
03
Measurement of groove diameter
picture
The picture suggests using a thin micrometer:
picture
picture
Reason: The measuring surface is a thin sheet, which can easily and accurately measure the diameter of narrow grooves.
The picture suggests using a thin caliper:
picture
picture
Reason: The front end of the measuring claw is thin-shaped, which can easily reach the measuring position of the narrow groove to complete the measurement.
It is recommended to use the blade thickness table for the picture:
picture
Reason: The front end of the measuring claw is in the shape of a sheet, which can easily reach the measuring position of the narrow groove to complete the measurement.
04
Inside diameter measurement with groove
picture
picture
It is recommended to use a grooved micrometer:
picture
picture
Reason: The micrometer screw and anvil with flange can measure the inner diameter of the groove and the depth and position relationship of the groove in the pipe.
The picture suggests using a hook-type vernier caliper:
picture
picture
Reason: The front end of the measuring claw is hook-shaped, which can measure the size of the stepped groove of the inner diameter of the cylinder.
05
Spline measurement
picture
The picture suggests using a spline micrometer:
picture
picture
Reason: The small diameter anvil makes it easy to measure the diameter of spline shafts and grooves.
06
Outer diameter measurement of odd-numbered flute tap reamers
picture
The picture suggests using a V-type anvil micrometer:
picture
picture
Reason: V-shaped anvil is suitable for measuring the outer diameter of taps, reamers and milling cutters with odd number of grooves, and can use a single needle to measure the pitch diameter.
07
Measurement of plate center thickness
picture
The picture suggests using a plate thickness micrometer:
picture
picture
Reason: The extra large ruler frame can easily measure the thickness of the board.
08
Measurement of common normal length
picture
The picture suggests using a disk micrometer:
picture
picture
Reason: The disc-type anvil can penetrate deeply into the tooth root and is suitable for measuring the tangential length of the tooth root of spur gears and helical gears.
09
Diameter measurement of gear balls
picture
The picture suggests using a gear outer diameter micrometer:
picture
picture
Reason: Different replaceable ball-type anvils and micrometer screw measuring surfaces can be selected to measure gears of different modules (0.5 - 5.25).
10
Measurement of effective thread diameter
picture
picture
It is recommended to use a threaded micrometer:
picture
picture
Reason: The fixed anvil can measure 60° threads. The effective diameter of the thread is read directly without calculation.
The picture suggests using a threaded micrometer with replaceable anvils:
picture
picture
Reason: Optional replaceable measuring anvil/micrometer screw measuring surface, corresponding to the measurement of different threads. The effective diameter of the thread is read directly without calculation.
11
Measurement of hole center distance
picture
The picture suggests using an offset centerline caliper:
picture
picture
Reason: With offset value setting function, the distance measurement value can be read directly.
The picture suggests using a center-center type back-jaw type offset caliper:
picture
picture
Reason: With offset value setting function, the distance measurement value can be read directly.
12
Measurement of single hole spacing
picture
The picture suggests using an edge-center type back-jaw type offset caliper:
picture
picture
Reason: The edge-center type measuring claw is suitable for measuring the distance between single holes, and the measuring claw is provided on the back of the ruler frame to facilitate reading the measurement results from above.
13
Dimensional measurement of irregular narrow areas
picture
picture
It is recommended to use pointed claw calipers:
picture
picture
Reason: The pointed claw measuring claw can penetrate into very small grooves or tracks, easily achieving measurements of outer diameter, inner diameter, depth and step.
14
Thickness measurement of stenosis
picture
The picture suggests using a pointed claw micrometer:
picture
picture
Reason: The anvil tip radius is about 0.3mm, which can be used to measure wall thickness dimensions that are difficult to measure such as drilled holes, small grooves, and key grooves.
15
Dimensional measurement of step difference parts
picture
The picture suggests using an offset caliper:
picture
picture
Reason: The measuring claw design with different heights is suitable for measuring step sections and workpiece dimensions that are difficult to measure.
16
Wall thickness measurement of recesses
picture
The picture suggests using a spherical anvil wall thickness micrometer:
picture
picture
Reason: The two measuring surfaces are spherical and can measure the thickness of the concave wall.
