L-37LRoundtestTo realize efcient centering and leveling combined with high-precision measurement Mitutoyo 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 RA-H5200SERIES 211 — Roundness/Cylindricity Measuring SystemA high-performance automatic model equipped with a high-speed automatic centering/leveling function achieves the world's highest-level of accuracy.•A turntable with a highly rigid air bearing is incorporated to attain the industry leading rotational accuracy of (0.02+3.5H/10000)µm•High-speed automatic centering/leveling function contributes to a signicant reduction in the man-hours required for setups.•The analysis program (ROUNDPAK) employs Windows OS to provide user-friendly screen and easy operation through the use of the mouse and icon selection.•It is a full-automatic model which performs processing automatically from part program calling, centering/leveling, measurement, calculation, all the way through to printing.•Capable of continuous inside/outside diameter measurement without changing the detector position. (up to ID ø50mm)•The automatic positioning function of the turntable enables automatic measurement in combination with table rotation and slider/column movement.•The measurement range is extended by the X-axis tracking measuring function. This function is useful when the roundness/cylindricity displacement or the taper obtained from the slider/column movement is too large and the detector's measuring range is exceeded. (Tracking measurement range: 5mm)•The spiral-mode measurement function combining table rotation and rectilinear action is enhanced.It performs multiple-prole measurement in one cycle of measurement, and loads cylindricity or atness data as a continuous data set.•Advanced graphical analysis such as a power spectrum chart is available.•A sliding mechanism is incorporated in the detector holder. It enables one-touch measurement of a workpiece with a deep hole having a thick wall, which has been difcult with the standard detector. To perform measurement, the contact point can be positioned higher than the workpiece, and then the detector holder is simply lowered. Furthermore, internal/outside diameterscan be easily measured with the continuous ID/OD measurement function.Centering and leveling iscomplete withing 1 minTilting: 520µm150mmEccentricity: 200µmRA-H5200AHwith side tableSPECIFICATIONSModel No.RA-H5200ASRA-H5200AHTurntableRotational 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, 10rpm (On auto-centering: 20rpm)Effective diameter of the tableø300mmCentering adjustment range±5mmLeveling adjustment range ±1°Maximum loading mass80kg (On auto-centering: 65kg)Maximum probing diameter ø400mmMaximum loading diameterø680mmVertical movementStraightness of traverse (λc2.5)Narrow range0.05µm/100mmWide range0.14µm/350mm0.2µm/550mmParallelism to the rotation axis (with respect to the generating line)0.2µm/350mm0.32µm/550mmTravel range (from the table top)350mm550mmMoving speedMaximum: 60mm/s (at measurement: 0.5, 1, 2, 5mm/s)Maximum probing height350mm550mmMaximum probing depth (when using a standard stylus)ø32×85mm (depth)ø7×50mm (depth)X axisStraightness (λc2.5)0.4µm/200mmPerpendicularity to the rotation axis (with respect to the generating line)0.5µm/200mmTravel range225mm (–25mm to +200mm from the rotation center)Moving speedMaximum: 50mm/s (at measurement: 0.5, 1, 2, 5mm/s)DetectorMeasuring forceApprox. 10 to 50mN, 1 to 5 stepsStylus tip form, materialø1.6mm CarbideDetection rangeStandard±400µm/±40µm/±4µmTracking±5mmOthersIn/out switching feature, Measuring force switching feature (5-step), Stylus angle graduations (±45°), Z-direction collision detection func-tion, sliding detector holder (3 positioning)OthersRequired air pressure0.39MPaAir consumption (in normal state)45L/min (120L/min or more as air source)MassMeasuring main unit650kg670kgVibration isolator170kgAn inspection certicate is supplied as standard.
