Pneumatic Shaft Deflection Sensor System

Non-contact, high-accuracy shaft deflection sensor system. Compressed air is used for measurement, requiring no wiring in the spindle

We have developed a new spindle shaft deflection measurement system for machine tool spindles that combines air micrometer and oil-air technologies. The non-contact, high-accuracy system eliminates the need to worry about wiring and installation, which can become obstacles when introducing sensors.

Features

1

Air micrometer technology achieves non-contact, high-accuracy measurements.

2

Using oil-air lubrication, the system is compact and easy-to-implement close to spindle bearings.

3

No wiring is required in the spindle, making the system unaffected by electrical noise from the motor.
