Roundness/Cylindricity Measuring System

ROUNDTEST RA-1600

Catalog No.E15000(5)Powerful Analysis Performance in a Compact Form

Can measure awide variety ofworkpieces

Multi-functionalanalysis system

Realizes a wide measuring range in a compact form
• Max. probing diameter: 280 mm• Vertical travel: 300 mm• Max. table loading: 25 kg

Incorporates flexible data analysis software ROUNDPAK• Measurement results displayed in a graphics window• Easy to operate thanks to a simplified measurement mode
• Can simulate a part program

High-level functions promote greater efficiencyEquipped with a highly accurate turntable that enables simple andaccurate centering and leveling of the workpiece
The table provides high rotational accuracy (radial 0.02+6H /10000 μm; axial 0.02+6X/10000 μm), enabling the system tomeasure flatness and other characteristics, in addition toroundness/cylindricity, at a level that suits any application.
The RA-1600 has also inherited the D.A.T. (Digital AdjustmentTable) mechanism used in top-end devices to make workpiececentering and leveling quick and easy. The operator simply hasto manipulate the digital micrometer heads of the turntable tomatch the adjustment values displayed on the monitor. Even
notched workpieces can be measured accurately.
Centering and leveling operations carried out by using theD.A.T.* can also be incorporated into the measurement
procedure (part program). This prevents human errors when
performing centering and leveling, and helps standardize
measurement operations executed by the part program.

D.A.T. (Digimatic Adjustment Table)
A guidance system (D.A.T.) is incorporated into the turntables on the RA-2200DS/
DH models to help the operator perform manual centering and leveling smoothlyand simply.

Even if a workpiece cannot be measured by physically rotating it
by a full turn due to some obstruction (projection), segments ofthe circumference
can be measured.

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 whendisplacement due to form variation exceeds
the measuring range of the detector, andX-axis motion is necessary to maintaincontact with the workpiece surface.

Sliding detector-unit holder (Option)
Safety mechanism provided as astandard feature
A collision-sensing function has been
added to the detector unit (when it is in
the vertical orientation) to prevent
collision in the Z-axis direction.
Additionally, an accidental collision
prevention function, which stops thesystem when the detector displacement
exceeds its range, has been added. Whenan accidental touch is detected, thededicated analysis software (ROUNDPAK)
senses the error and automatically stops the system.

The detector-unit holder is equipped with a sliding mechanism,
enabling one-touch measurement of a workpiece with a deephole having a thick wall, which has been difficult with theconventional standard arm.

Sliding distance: 112 mm

The detector-unit holder can be stopped
at a position sufficiently higher than theworkpiece along the Z-axis, and thenlowered and positioned to makemeasurements.
Furthermore, internal/external
diameters can be easily measured withthe continuous internal/external
diameter measurement function*.
*: See this page for details about the continuous ID and OD measuring function.

The customer can create reports in custom formats by specifying
how the analysis results will be displayed, as well as the sizes andpositions of graphics. The analysis result window can be directly
utilized as a layout window. Since the measurement procedure,
including the layout information, is saved, the entire process, frommeasurement start, calculation, result saving, and finally toprinting, can be automatically executed.
