In-Spindle AE Sensors
Rotary Non-Contact Acoustic Emission (AE) Sensors for dresser spindles
The in-spindle AE sensors are non-contact and come in two formats. These include a telescopic type and spiral-cable type. The telescopic type has a slide tube to facilitate installation and it sits inside a 4mm bore within a grinding machine spindle or rotary diamond dresser unit. This configuration allows the acoustic sensor to spin with the spindle and to be in close proximity to the grinding event, giving a clear uninterrupted signal.
