Roundtest RA-2200 SERIES 211 — Roundness/Cylindricity Measuring System

• Highly accurate and easy-to-use turntable
The 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 flatness is assured. A turntable with an automatic centering and leveling function is adopted for RA-2200AS/AH as a standard feature, which frees operators from manual centering and leveling operations. Furthermore, for the RA-2200DS/DH models, a guidance system is incorporated as a standard feature help untrained operators perform centering and leveling simply and smoothly.
• Greater productivity achieved by continuous inside/outside diameter measurement
Both the ID and OD of a workpiece can betraced in succession without changing the detector traverse direction.
• Sliding detector holder is equipped as standard
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 difficult 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 diameters can be easily measured with the continuous ID/OD measurement function.
• Positioning sensor equipped to enable high accuracy repetitive 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 repetitive measurement.
• Safety mechanism provided as a standard feature
A collision-sensing function is equipped in the detector unit (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.
