L-38LMitutoyo operates a policy of continuous improvement that aims to provide the customer with the benet of the latest technological advances.Therefore the company reserves the right to change any or all aspects of any product specication without notice.Roundtest Extreme RA-2200 CNCSERIES 211 — CNC Roundness/Cylindricity Measuring SystemRA-2200CNCSystem vibration isolator (with side table)•Highly accurate and easy-to-use turntableThe rotational accuracy in the radial direction is better than 0.02+3.5H/10000µm, and in the axial direction 0.02+3.5X/10000µm is achieved. High accuracy measurement of not only roundness or cylindricity but also atness is assured. Also, the turntable with automatic centering and leveling function is equipped as standard, which frees operators from manual centering and leveling operations.•A function to change the detector posture enables CNC automatic measurement.Automatic control of holder arm posture (vertical/horizontal) and the rotation feature of the detector (rotates in 1° increments in the range of 0 to 270°) enables continuous measurement of various feature combinations, such as OD/ID and/or top/bottom plane measurements. Also, an off-line teaching function allows easy part program creation.•A positioning sensor to achieve CNC high-accuracy automatic measurement.A Mitutoyo linear scale is used in the X-axis drive unit to directly detect the position of the drive unit. It guarantees the highly precise positioning vital for automatic measurement.•A roughness detector is supportedAn optional surface roughness detector enables measurements in the circumferential. radial and axial directions with the workpiece held stationary as required.Refer to the Roundtest RA-2200 series (Catalog No.E4385) for more details.SPECIFICATIONSModel No.RA-2200 CNCZ-axis column unitStandard column specication(Vertical travel: 300mm)High column specication(Vertical travel: 500mm)TurntableRotational accuracy(JIS B 7451-1997)Radial direction(0.02+3.5H/10000)µm H: Probing height (mm)Axial direction(0.02+3.5X/10000)µm X: distance from the center of rotation (mm)Rotational speed2, 4, 6, 10 rpmEffective diameter of the tableø 235mmCentering/leveling mechanismA.A.TCentering adjustment range±3mmLeveling adjustment range ±1°Maximum loading mass30kgMaximum probing diameter ø 256mmMaximum loading diameterø 580mmVertical movement(Z-axis column unit)Straightness of traverse (λc2.5)Narrow range0.10µm/100mm0.10µm/100mmWide range0.15µm/300mm0.25µm/500mmParallelism to the rotation axis (with respect to the generating line)0.7µm/300mm1.2µm/500mmTravel range300mm500mmMoving speedMaximum: 50mm/s (at measurement: 0.5,1.0, 2.0, 5.0 mm/s)Maximum probing height300mm500mmMaximum probing depth (when using a standard stylus)ø12.7×26mm (depth), ø 32×104mm (depth)X axisStraightness (λc2.5)0.7µm/150mmPerpendicularity to the rotation axis (with respect to the generating line)1.0µm/150mmTravel range175mm (–25mm to +150mm from the rotation center)Moving speedMaximum: 30mm/s (at measurement: 0.5, 1.0, 2.0, 5.0 mm/s)DetectorMeasuring forceApprox. 40mNStylus tip form, materialø1.6mm CarbideDetection rangeStandard±400µm/±40µm/±4µmTracking±5mmOthersRotation mechanism (rotates in 1° increments in the range of 0 to 270°)OthersPower supply100-240VACRequired air pressure0.39MPaAir consumption30L/min in normal state (80L/min or more as air source)Main unit weight180kg200kgAn inspection certicate is supplied as standard.
