L-33LRoundtestTo 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.It is a cost-effective compact machine that enables full-scale roundness evaluation.•Offers easy operation for anyoneA large, simple key arrangement is used. Conveniently situated adjustment wheels for the vertical direction (Z axis) and the radial direction (X axis) are provided on the slider for excellent operability.•High accuracy provided by a low-cost machineThis model uses an air bearing to guarantee best performance. Rotational accuracy as high as (0.04+6H/10000)μm is offered, assuring a precision that is comparable to that of upper-grade models.•User-friendly operationMeasurement results and recorded proles are easy to view with the large LCD, and can then be printed by the built-in thermal line printer. The machine has a compact body to enable installation in congested inspection areas. Furthermore, optional functions to improve usability can be offered.Roundtest RA-10SERIES 211 — Roundness Measuring InstrumentMount the workpiece on the the holding xture.Position the detector in contact with the workpiece.* If zero-set function or X-axis stop (optional) is used, repetitive measurement of identical workpieces can be performed efciently.Press the "Condition" button as required.*If measuring with the same conditions as were used in the previous session before power was turned off, pressing the condition button is not required.Simple measurement procedurePress the "START/STOP" button.(1)Collet chuck holder and collet chuck(2)Z axis ABS scale(3)X axis stopRefer to the Roundtest RA-10 (Catalog No.E4319) for more details.SPECIFICATIONSModel No.RA-10TurntableRotational accuracy(JIS B 7451-1997)Radial direction(0.04+6H/10000)µm H: Probing height (mm)Axial direction(0.04+6X/10000)µm X: distance from the center of rotation (mm)Rotational speed6rpmEffective diameter of the tableø150mmCentering adjustment range–Leveling adjustment range–Maximum probing diameterø100mmMaximum loading diameterø320mmMaximum loading mass10kgVertical movementVertical travel117mmMaximum probing height152mmMaximum probing depthø30×100mm (depth), ø7×50mm (depth)X axisTravel range 75mm (–25mm to 50mm from the rotation center)Detector*1Measuring range±1000µmMeasuring force100mN (± 30%)Stylus tip formø1.6 Carbide*1: Only the standard length stylus is applicable to this detector.
