产品简介 brief
仪器用以评定轴承内外圈滚道表面粗糙度。仪器也可测量平面、斜面、球面、外圆柱面、内孔表面、深槽表面，圆弧面及微小零件的粗糙度，所以在机械、模具等行业中广泛使用。
仪器通过精密的机械定位装置，不同规格的轴承可以在几分钟内便能调到准确的位置进行测量。仪器采用不带导头的电感型传感器，保证能精确地在轴承滚道内自动测量，测量软件能动态显示轴承滚道形状，可选择不同位置测定粗糙度参数，并可显示轮廓、tp曲线等；仪器还可以通过打印机打印出所有的参数和曲线。

jb-2c roughometer, is specially used to evaluate surface roughness of internal and external roll paths of bearings .it can also be used to measure the roughness of parts in forms of plane, sphere and of small size.
a skidless inductive transducer is adopted, that automatically and precisely performs scan and measurement on the roll path of bearing .
it is equipped with a computer and a special-purpose software. the roll-path profile of bearing is dynamically displayed on the screen, and different position of measurement of the bearing can be se-lected. all the measured roughness data, and the bearing"s profile and tp curve are displayed, and, if required, can be printed out.
