JB-5C粗糙度轮廓仪广泛应用于机械加工、汽车、轴承、机床、摸具、精密五金、光学加工等行业。仪器驱动箱提供了一个行程为100毫米长的高精度直线基准导轨，传感器沿导轨作直线运动，位移量通过精密光栅位移传感器进行数据采集。驱动箱可通过水平调节钮作±10度的水平调整，并可分别通过控制箱的操作键或软件界面进行水平和垂直方向的移动。仪器带有电脑及专用测量软件，在WINDOWS XP操作系统下的测量软件操作直观方便，功能丰富。

可测量各种精密机械零件的粗糙度和轮廓形状参数。用拟合法可评定半径、两圆中心距角度、距离等。从而可测量直线度、凸度、沟心距、倾斜度、垂直距离、水平距离、台阶等形状参数。

It is widely used in metrological departments of industries of autos, tools, bearings, Patterns, and optics for measuring profile and roughness of precision parts. The drive box is equipped with a straight-line guide of high accuracy traveling up to 100 mm. The displacement of the transducer moving along the guide collected with a precision grating system. The transducer is operated with either keys on the control box or the buttons on the window interface. The JB-5C software runs on Windows XP.

It is used to measure the form and roughness of profiles of precision parts. In addition to roughness, by fitting least-square line of nominal form, a variety of form parameters can be measured, such as radius, angle, straightness, convexity, vertical and horizontal distance, and distances between points, circles, and slots.
