ROUNDTEST RA-H5200 SERIES

Catalog No.E15011(2)Form Measurement

High-precision Roundness / Cylindricity Measuring System

World-class Accuracy with Simple Operation

ROUNDTEST RA-H5200
Continuous OD/ID measurement function

World-Class Accuracy

Continuous internal/external
diameter measurement ispossible without changing thedetector position.

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 airbearing that provides superior rigidity. The resulting rotational accuracy, the heart of
the roundness/cylindricity measuring system, is world-class at (0.02+3.5 H/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 becompletely 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.

Attaining the ultimate level of improvement in the manufacturing
accuracy of the column guide surface, which is critical forachieving perfect straightness, and adopting Mitutoyo's
proprietary system and mechanisms have led to the achievementof the ultra-high column straightness of 0.05 μm/100 mm (innarrow range).

High accuracy even at high positioning speeds
Continual development has resulted in the highest drive speed
within the class.
•Vertical direction (Z-axis column): Max. 60 mm/s
• Radial direction: Max. 50 mm/s

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

Mitutoyo's linear encoders have been incorporated into thepositioning sensors in the X- and Z-axis drive units to directlysense the displacement the drive units, thereby achieving thehighly accurate positioning essential for repeat measurements.

The measurement accuracy of a roundness/cylindricity measuring systemis greatly affected by external disturbances such as vibration. Therefore,
the RA-H5200 is supplied as standard with a high-performance
vibration isolator that possesses excellent vibration attenuation.

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 usefulwhen displacement due to form variation
exceeds the measuring range of thesensor, and X-axis motion is necessary
to maintain contact with the workpiecesurface.

High-performance vibration isolator
as a standard feature

Simple and fast high-speed automatic centering and leveling
The centering/leveling mechanism section is equipped with highprecision glass encoders in each axis of the turntable unit to reduce
positioning errors and achieve high-speed automatic centering/leveling, greatly reducing the time from workpiece setting tomeasurement.
The Automatic Adjustment Table (A.A.T.) with centering/levelingadjustment is supplied as standard, which frees the operator fromthe task of centering and leveling the workpiece.

The spiral-mode measurement function combines tablerotation and rectilinear action allowing cylindricity, coaxiality,
and other data to be loaded as a continuous data set.

Spiral Measurement/Analysis

Surface-roughness measuring function (optional roughness unit)
The system is a multi-sensor type, compatible both with a standard
probe that meets the specifications of the roundness measuringsystem and a surface roughness detector unit.
Incorporating the optional roughness detector unit into the systemenables roughness measurement in the circumferential direction
around the θ-axis, as well as in the direct-drive directions along theX- and Z-axes with the table stopped. Thus, surface roughness andgeometric tolerances, such as roundness and cylindricity, can both bevalidated using only a single system.

RA-H5200 PLUS

A roundness/cylindricity measuring system developed to combine
world-class accuracy with high maneuverability/analytical capability.
This system can perform many other functions as well, such as
tracking measurement and automatic OD/ID measurement.
Available with the standard column specification (Z-axis traverse of
350 mm) or an extended specification (Z-axis traverse of 550 mm)
for handling taller workpieces.

This system combines high accuracy with automatic measurements
to greatly improve productivity and efficiency. Automatic orientation
control for the detector unit enables this system to automatically
execute high-speed, operator-less measurements. Available withthe standard column specification (Z-axis traverse of 350 mm) oran extended column specification (Z-axis traverse of 550 mm) forhandling taller measurement workpieces.

Sliding detector-unit holder
provided as a standard feature
The detector-unit holder
is equipped with a sliding
mechanism, enabling one-touchmeasurement of a workpiecewith a deep hole having a thickwall, which has been difficult
with the conventional standardarm.
Sliding distance: 112 mm

Retrofit kits can be used with models equippedwith motorized detector-unit holders
Retrofit kits are available for the RA-H5200AS and RAH5200AH to add the automatic measurement functionality
found in their PLUS counterparts.
*See page 5 for details.

Safety mechanism provided
as a standard feature

Patent pending in Japan

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-axis
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, thededicated analysis software (ROUNDPAK) senses the error andautomatically stops the system.

Changes the detector-unit holder orientation
for automatic measurement
This function controls the orientation of the holder armof the detector unit (between vertical and horizontal)
and the detector unit rotation mechanism (in 1-degreeincrements to match the tilt angle of the measurement
workpiece), making it possible to measure internaland external diameters as well as top and bottom
surfaces continuously and automatically. Additionally,a fully-featured offline teaching function simplifies thecreation of part programs.

Detector unit II (option)
This highly adjustable detector unit can be installed on
motorized detector-unit holders.
Features of this detector unit include the ability to use
alternative styli for the RA-H5200* and freely change
the angle of the stylus.
*See page 8 for alternative styli.
