PULCOM GE Series

PULCOM GE series detect the contact between the grinding wheel and the work piece and send the signal to NC immediately. Using this signal, NC can increase the feed rate of the air cutting to reduce the cycle time. And also NC can grind the constant amount from the surface of the workpiece.

PULCOM GE series detect the contact between the grinding wheel and the dresser and send the signal to NC immediately. Using this signal, NC can prevent the product failure caused by missed dressing. And also NC can confirm the completion of the dressing cycle 
by monitoring the continuousness of touch signal. NC will dress only the necessary parts prolonging lifetime of the grinding wheel.

PULCOM GE series detect the contact between the grinding wheel and the machine parts and send the signal to NC immediately. Using this signal, NC can stop immediately the machine to avoid collision and minimize the damages of spindle, grinding wheel, and so on.

The latest digital noise reduction technology using DSP (Digital Signal Processer) archive the high performance of the noise reduction. The signal to noise ratio of this digital filter is about six times higher than the analog filter.

PULCOM GE series have the exclusive filter for canceling the spike noise which is a frequent cause of false detection. The delay of this filter is less than the conventional analog filter, so the response is high speed. The response speed to the square pulse 
input is about eight times faster than the analog filter.

A variety of high sensitivity AE sensors are prepared for various applications (Please see the sensor selection guide in detail) . These AE sensors have the pre-amplifier inside (or outside), and can amplify a weak AE signals.

In order to our customer use with confidence, the PULCOM GE-Series have a sensor breakdown diagnosis function installed. When the measuring starts, it will send a diagnosis AE pulse to each of the sensor (s), and will use the reflecting pulse to diagnose any sensor fault and the sensitivity degradation. Therefore, long term reliability can be ensured.

The frequency of the detected AE pulse is analyzed, then the power spectrum will be displayed in real time. The defects which could not be detected only by the AE pulse strength will be detected.

GE-20, 11 can store 16 patterns of detection settings to support the multi work processing and applications.
Because GE-20, 11 can measure with optimum detection setting selected by NC through IO signals, the setting change by the operator is not necessary.
