L-35LRoundtestTo 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.•Compact body and a wide measuring range assures precision that compares well with that of higher-grade models.Maximum probing diameter: ø280mmVertical travel: 300mmMaximum table loading: 25kgRotational accuracy in the radial direction: (0.02+6H/10000)µmRotational accuracy in the axial direction: (0.02+6X/10000)µm•D.A.T. (Digital Adjustment Table) function aids manual workpiece centering and leveling.•Safety mechanism provided in the detection section as a standard feature. A collision-sensing function is equipped in the detector (when it is in the vertical orientation) to prevent a damaging collision in the Z direction. Additionally, an overrun prevention function is equipped, which stops the system when the detector displacement exceeds its range.•A sliding mechanism (optional sliding detector holder) can be installed 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.•The measurement results are shown graphically if using the roundness/cylindricity analysis software (ROUNDPAK).Roundtest RA-1600SERIES 211 — Roundness/Cylindricity Measuring SystemResult screenRefer to the Roundtest RA-1600 (Catalog No.E15000) for more details.SPECIFICATIONSModel No.RA-1600TurntableRotational accuracy(JIS B 7451-1997)Radial direction(0.02+6H/10000)µm H: Probing height (mm)Axial direction(0.02+6X/10000)µm X: Distance from the center of rotation (mm)Rotational speed4, 6, 10rpmEffective diameter of the tableø150mmCentering/ leveling adjustmentD.A.T.Centering adjustment range±3mmLeveling adjustment range±1°Maximum loading 25kgMaximum probing diameterø280mmMaximum workpiece diameterø560mmVertical movementStraightness of traverse (λc2.5)Narrow range: 0.20µm/100mm, Wide range: 0.30/300mmParallelism to the rotation axis (with respect to the generating line)1.5µm/300mmMoving speedMaximum: 15mm/s (at measurement: 0.5, 1.0, 2.0, 5.0 mm/s)Vertical travel300mmMaximum probing height300mm*1Maximum probing depth (when using a standard stylus)ø32×91mm (depth), ø7×50mm (depth)X axisStraightness (λc2.5)2.7µm/140mmPerpendicularity to the rotation axis (with respect to the generating line)1.6 µm/140mmTravel range165mm (–25mm to +140mm from the rotation center)Drive speedMaximum: 8mm/s (at measurement: 0.5, 1.0, 2.0, 5.0 mm/s)DetectorMeasuring force10 to 50mN, 1 to 5 stepsStylus tip form, materialø1.6mm CarbideDetection rangeStandard±400µm/±40µm/±4µmTracking±5mmOthersIn/out one-touch switching feature, Z-direction collision detection function, stylus angle graduations (±45°)OthersPower supply100-240VACPower consumption80W (PC and printer excluded)Required air pressure0.39MPaAir consumption22L/min in normal state (80L/min or more as air source)Main unit mass170kg*1: Auxiliary stage for a low-height workpiece is required for the measurement 20mm or less from the table top.D.A.T.
