Accurate Detection

”True run-out quantity” is calculated by storing the shape of the tool flange in the controller without run-out state and comparing it with the shape of the run-out which is measured just before machining. More highly accurate run-out measurement is achieved in comparison with the simple run-out measurement (repeatability:30μm) by using general eddy-current sensors.

Interpolation of Notched Part

By using proprietary algorithm, reliability of the run-out measurement is improved by interpolating the notched part of the tool holder, which is the decreasing factor of the measurement accuracy.

Oversampling Method

Sampling number is automatically increased by proprietary software operation process and interpolation accuracy of the tool holder notched part is improved.

0.3 second Measuring Time

Although it is very difficult to achieve run-out measurement at 600rpm by using contact type, it is achieved by using noncontact method. An eddy-current sensor allows measurement in a mere 0.3 seconds (at 600 rpm). Since the measuring tool is selectable, measuring time is not affected by the cycle time. A dedicated run-out detection system algorithm (patent pending) calculates true run-out for detection capability that cannot be achieved by commercially available eddy sensors. All of this means that the system delivers precise, reliable detection in an automated line.

Sensor Head Automatic Tuning Function

Replacing only the sensor is possible if damage occurs to the sensor for any reason. After replacing the sensor, combination adjustment of controller and sensor head is completed by removing the tool holder from the spindle and clicking “sensor adjustment” button once.

Most Suitable for Machining Environment

This run-out detection measuring system is coolant-resistant.
