AE sensor System


The touch sensor system quickly detects the machining starting point with submicron precision.


This is a high-precision touch detection system. With AE sensor technology, it quickly detects the touch of a workpiece or a dressing tool while in the submicron processing or high-precision processing of a grinding machine or a machining center.
The information will be sent to a machine tool by signal output or to an operator by vibration and lighting.
Does not require technical experience.

What is AE?

AE stands for Acoustic Emission and means the phenomenon of radiation of elastic waves in solids when deformation or collapse occurs.
The large AE would occur when a grinding wheel contacts a workpiece while a grinding machine is in operation.
AE sensor Systems 'MyTENTA-1' and 'MyTENTA-1 PB' detect the machining starting point of high-precision processing by detecting AE wave with high sensitivity, utilizing the noise filter and signal processing.


Easy operation

Easy button operation for sensitivity adjustment or threshold setting
Requires only a minimal amount of operation for the touch detection.
