Measurement in 0.3second! Accurately detects run-out of 5μm. *1
ATC run-out detection system is used to detect abnormal run-out of the tool caused by entering the tool taper and to prevent machining defects. n Accurate Detection l Accurate Detection
Tool
”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.

l Interpolation of Notched Part
l Oversampling Method
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.
Sampling number is automatically increased by proprietary software operation process and interpolation accuracy of the tool holder notched part is improved. Interpolation accuracy is improved

l High Speed Measurement
l Sensor Head Automatic Tuning Function
Although it is very difficult to achieve run-out measurement at 600rpm by using contact type, it is achieved by using non-contact method. In addition, by using proprietary algorithm, all the measuring processes are completed in merely 0.3 seconds (at 600rot/min).
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.
n Easy Operation
Automatic adjustment at once
l Simple Setup By just adding one line [ M132 ] ··· Tool registration [ M133 ] ··· ZDetect run-out
l Standard attachment of ACCRETECH Sensor Bracket, Controller box, etc.
l Most Suitable for Machining Environment This run-out detection measuring system is coolant-resistant.
