GE system detects the generated AE wave by grinding, etc.

PULCOM GE-20

Applications

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.

Gap control

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.

Crash detection

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.

Doressing control

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.

Feature

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.
