The RA-2200 provides high accuracy, high speed and high performance in roundness measurement. The fully-automatic, or DAT (Digital Adjustment Table), function-aided manual workpiece centering and leveling offers what used to be a difficult task into one that is simple enough for even new users to perform.

Features & Benefits
The Roundtest Extreme RA-2200 CNC Roundness/Cylindricity and Surface Roughness Measuring System performs highly accurate roundness and cylindrical measurements at high speeds in an easy-to-use machine. Roundness and surface roughness measurements are both available from a single measuring system which eliminates workpiece resetting for roughness measurement. Roughness measurement is possible in the axial and circumferential directions.
- Programmable detector unit and holder arm greatly contributes to productivity improvement and enhanced measurement efficiency
- Offline teaching function is capable of creating part program without measurement which allows confirmation of collision-free simulations
- Available with the standard column specification or a high column specification for taller workpieces
- Highest rational accuracy in the radial direction together with high linear displacement accuracy in the axial direction offers high accuracy measurements in both roundness/cylindricity and flatness
- Comes complete with powerful data analysis software ROUNDPAK, which requires only simple manipulation using a mouse and icons, achieving enhanced functionality and ease of operation
- With extremely high rotational accuracy, both in the radial and axial directions, the turntable allows high accuracy flatness testing to be performed in addition to roundness and cylindricity measurements
- The incorporation of an automatic centering/leveling turntable (A.A.T.) with the RA-2200AS/AH models relieves the operator of the bothersome task of workpiece centering and leveling
- High repeatable measurements are achieved using Mitutoyo designed linear scales in the X/Z drive unit to guarantee the high precision positioning so vital for repetitive measurement
