Features

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.

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 supply to control
Measurement is done by electricity, so management of the measuring air is not required.
Notice)
1. Air blow to remove the chips before measuring the workpiece is necessary.
2. Depending on the workpiece material, the contact may leave some marks.

Applications

BG-04 ・BG-10A

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

BG-10A-502

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

 

BG-03

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).

 

BG-10A-503

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).

 

BG-10A-501

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