List of Measuring Methods

Diameter/Roundness

Inner Diameter

Air Micrometer Diameter/Roundness Inner Diameter image

Inner diameter can be measured by inserting a plug type measuring head with air blow nozzles on both sides. Taper can be measured by moving the head in the axial direction.

Roundness (cylindricity) can be measured by rotating the measuring head one revolution.

Contact type indirect air blow head (leaf type) is used when the measuring surface is confined or rough.

Outer Diameter

It can measure outer diameter when head put on the work, and can measure taper by moving to axial direction.

Average Diameter/Triangle

Inner Diameter

The average inner diameter can be measured by placing three or more jets at equiangular locations. Roundness can be measured by rotating the workpiece with three nozzles.

Outer Diameter

The average outer diameter can be measured by placing three or more nozzles at equiangular locations.Roundness deformation can be mea-sured by rotating the workpiece.

Roundness can be measured by mounting a nozzle on a stand and rotating the workpiece on a V stand or a measuring stand.

Depth

Air Micrometer Depth

Use an exclusive measuring instrument with a precision head.
Depth can be measured inserting the workpiece.

Flatness

Air Micrometer Flatness

Move a workpiece to the right and left on a nozzle built-in measuring stand, or use a dedicated measuring unit with several built-in nozzles to measure flatness.

Straightness

Inner Diameter

Outer Diameter

Air Micrometer Straightness

Rotate a measuring head with four nozzles like the one shown above180° in order to measure Straightness.

Concentricity

Air Micrometer Concentricity

Concentricity can be measured by measuring the wall thickness.

Squareness can be measured by rotating a dedicated measuring head with a stepped nozzle as shown above 180°.
Squareness is measured by providing a nozzle on one side of the workpiece.

Parallelism

Air Micrometer Parallelism

Parallelism can be measured by using a similar procedure like the one used to measure squareness.

Taper

Inner Diameter

Taper can be measured from the dif-ference in float position by simply inserting the workpiece.

Height

Air Micrometer Height

Measurement can be performed from a nozzle mounted on a stand.

Thickness

Air Micrometer Thickness

Using a measuring head with air blow in both sides eliminates error due to dust or warp.

Distance Between Centers

Air Micrometer Distance Between Centers

The distance between centers can be measured from the difference in the movement of the floats by simply placing the workpiece inside.

Multi-Point Simultaneous Measurement

Air Micrometer Multi-Point Simultaneous Measurement

The dimensions at multiple points can be simultaneously measured by using an exclusive measuring instrument. This permits one-time judgment of the workpiece to know if it is under the tolerance by simply placing it in the device.
