Inner-Diameter Measuring Head for Post-Process.

High Precision

These heads provide the high precision required for inner diameter post-process measurements.

Diverse Measurements

Measuring heads are available for a diverse range of measurements, including one diameter, two diameters, ellipse, average diameter, hole with steps and taper.

Superior Cost Performance

Standardization of the main unit, guide, fingers and contacts has eliminated the necessity of new designs for most parts. This has allowed us to produce them more quickly and inexpensively.

Complete Easy Mount Options

The components that support the measuring head such as the floating relieving unit and relieving unit are also standardized. This eliminates damage to the measuring unit do to machining errors and improper positioning.

No Air to Control

Since the unit is driven by electricity, management of the measuring air is not required.

Inner Diameter Measurement of Transmission Cases

Insertion measurement for inner diameter at two locations on one side and one location on the opposite side can be performed.

Inner Diameter Measurement of Piston Pin Holes

Two pin holes are sequentially measured, and two-direction measurement can be performed (Model BG-03 / BG-04).

Two-Step Inner Diameter Measurement (different diameters)

The inner diameter of two locations with different diameters can be simultaneously measured (judged). This is ideal for automatic measurement immediately after machining.

Inner Diameter Measurement of Small/Large End Holes in Connecting Rods

Two holes can be simultaneously measured and two-direction measurement can be performed (Model BG-03 / BG-04).

Cylindrical Inner Diameter/Taper Measurement

Precise measurement of diameter at one location is performed. The measuring point can be moved to measure the taper at two locations (A, B).
