- This model uses a master ball calibration to correct the arc distortion (X-direction error) characteristic of a contour detector and has the ability to combine a flexible arm and a probe.
- Various contour measuring styli for a wide variety of workpieces from small holes to deep grooves.
In the case of a long workpiece like a ball screw, measuring with a conventional arm and probe position relationship resulted in interference with the detector, making it impossible to achieve a large measuring range in the X-direction. Master ball calibration creates a combination in which the arm and probe are downwardly offset, as shown in the photograph below, which allows unimpeded measuring, even in the case of long workpieces.
