Japan Sanfeng roundness tester cylindrical measuring instrument RA-1600
1. The compact size and wide measurement range ensure that its accuracy is comparable to higher-level models. Maximum measured diameter: ø 280mm Vertical movement distance: 300mm Maximum worktable load: 25kg Radial rotation accuracy: (0.02+6H/10000) μ m Axial rotation accuracy: (0.02+6X/10000) μ m
2. The D.A.T. (digital adjustment table) function helps with manual workpiece centering and leveling.
3. The detection section provides safety devices as standard features. The detector is equipped with collision sensing function (in the vertical direction) to prevent destructive collisions on the Z-axis. In addition, it is equipped with an over limit prevention function, which will stop the system when the displacement of the detector exceeds its range.
4. A sliding mechanism can be installed inside the detector bracket (optional sliding detector bracket). It is difficult to achieve standard detectors that can measure deep hole thick walled workpieces with a single click.
5. If roundness/cylindricity analysis software (ROUNDPAK) is used, the measurement results can be displayed graphically.
