Sensor
PULCOM GE-20
Process monitoring system (AE Sensor)
Reduce the cycle time and increase the production efficiency
■ The multi function controller which has 16 (2 items x 8 settings) measurement items
■ The color LCD with touch panel and icons
■ Easy operation
Gap detection
- ▪ Shorten the cycle time
- ▪ Zero position detection
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 increace 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.
Crash detection
- ▪ Protect the spindle from unexpected collision
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 for safety to minimize the damages of spindle, grinding wheel, and so on.
Doressing control
- ▪ Prevent the missed dressing
- ▪ Confirm the completion of the dressing cycle
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 can dress only a necessary parts to prolong the life of the grinding wheel.
Process monitoring
- ▪ Failure analysys of the processing
Monitoring the waveform of AE signal which is generated by the processing creates a visualization of the processing. This is useful for detecting the failure of the processing.
16 type settings
Controller can have maximum 16 settings ( 2 measuring items x 8 settings ) of each process.
Thus, it will be able to shorten the parameter resetting time after setup.
Color LCD display with touch panel
Intuitive operation is possible by color LCD view and touch panel function.

Easy setting
Parameter setting is easy more than conventional products through setting support function (auto noize cancel, auto gain control, etc.) .
When AGC button is touched, Sensor gain is set the suitable level.
PC Application for the exclusive use of GE-11 / 20.
This application is used a parameter setting , analyzing, confirm of test process, etc.
