World-Class Accuracy

High-accuracy, automatic centering/leveling turntable

A highly accurate, highly rigid turntable has been achieved through exceptional manufacturing accuracy of the critical components, in addition to a high-accuracy air-bearing that provides superior rigidity. The resulting rotational accuracy, the heart of the roundness/cylindricity measuring system, is world-class at (0.02+3.5H/10000)μm.

High-rigidity base

For a measurement system to be able to achieve high accuracy, the base, which forms the foundation of the system, must be completely rigid. Therefore, we utilized FEM structural analysis simulation to thoroughly analyze the base and its application. The result is the development of a high-rigidity base.

High-accuracy Z-axis column

Attaining the ultimate level of improvement in the manufacturing accuracy of the column guide surface, which is critical for achieving perfect straightness, and adopting Mitutoyo’s proprietary system and mechanisms have led to the achievement of the ultra-high column straightness of 0.05μm/100mm (in narrow range)

High-accuracy positioning sensors

High-speed automatic centering/leveling

The system is supplied as standard with the Automatic Adjustment Table (A.A.T.) positioning and leveling function, freeing the operator from the task of centering and leveling the workpiece. High- precision glass encoders are used to reduce positioning errors and achieve high-speed automatic centering/leveling, which contributes greatly to reducing the total measurement time from workpiece setting to workpiece measurement.

Measurement through X-axis tracking

Measurement while tracing is possible through a built-in linear scale in the X-axis. This type of measurement is useful when displacement due to form variation exceeds the measuring range of the sensor, and X-axis motion is necessary to maintain contact with the workpiece surface.

Safety mechanism provided as a standard feature

A safety mechanism is incorporated into the detector unit area. A collision- sensing function has been added to the detector unit (when it is in the vertical orientation) to prevent collision in the Z-xis direction. Additionally, an accidental collision prevention function, which stops the system when the detector unit displacement exceeds its range, has been added. When an accidental touch is detected, the dedicated analysis software (ROUNDPAK) senses the error and automatically stops the system.
