6 Adjust the digital micrometer heads on the rotary table by the amount indicated to correct the initial offset and inclination Preliminary measurement Displays amount of offset/inclination Simple adjustment Center of rotation Centering/leveling complete Rotary table Offset range adjustment: ±3 mm Inclination range adjustment: ±1 ° Workpiece Two preliminary measurements are made at cross-sections [A] and [B] Initial offset from center of rotation Initial inclination from table axis Center of rotation Rotary table Workpiece This instrument uses the D.A.T. (Digital Adjustment Table) function available on more sophisticated models, and this provides powerful support for centering and leveling operations. To perform such operations, the user need only adjust the digital micrometer heads attached to the rotary table by the amounts indicated by the display. This function also supports measurement of notched workpieces. RA-120 RA-120P Mode selection This function comes in very handy when outside diameter and inside diameter surfaces need to be measured repeatedly, for example, with respect to concentricity, deviation in wall thickness, etc. The inner surface can be measured and evaluated with the detector, maintaining the same measuring position for the outside diameter without changing its orientation, as illustrated on the right. Inside diameters down to 50 mm can be measured. Preliminary setup Centering Leveling D.A.T. function *except for centering/leveling device equipped with analog micrometer heads Continuous ID and OD measuring function Z-axis scale Functions that implement greater efficiency of measurement and range of analysis types Continuous inside and outside diameter function (outside dia. surface) This scale is useful when the measuring height position needs to be entered, such as when measuring concentricity, etc. The machine uses an ABS Digimatic scale unit to provide an effective means for repetitive measurement and position setting. Continuous inside and outside diameter function (inside dia. surface)
7 The range of this detector has been extended from that of a conventional lever head by as much as four times, and is now wider than ever before. The detector can provide sufficient margin for centering and leveling jobs, or when measuring large differences. Moreover, the measuring direction can be switched between inside and outside diameters with a single touch of a button.
