This is a compact roundness tester with D.A.T. (Digital Adjustment Table) function.
Available on backorder
By using a mouse and buttons, identified by corresponding icons, to control the machine, the Roundtest RA-120P’s interface provides excellent usability. Functions such as recalculation and graph reading are handled swiftly with easy-to-understand operations.
Complete with a wide range of functions including partial enlargement, auxiliary line setup, color change, displacement/angular difference of data between two points. Also equipped with notch processing and graph reading functions, which make the machine useful in research departments. Recalculation can also be performed when the filter and evaluation method is changed.

The turntable displays centering and leveling adjustments digitally, making this challenging task easy enough for even an untrained operator to perform, through these four simple steps:
1. Preliminary measurement of two cross sections on the workpiece.
2. The centering and leveling adjustment values are displayed.
3. The digital micrometer heads on the rotary table are adjusted to match the values displayed.
4. Centering and leveling is complete. [Centering range : ±3 mm – Leveling range : ±1°]
