Measuring items
Line and point elements of components surface, distance between point and point, line and line, position degree including distance, parallelism, perpendicularity, angle, groove depth and width, radius, able to analyze straightness, convexity and contour.  

Brief description for the scheme
With the issues of large volume, heavy weight that difficult to move to the measurement table, the scheme is aiming to place the measuring system on the generatrix of the components, by applying Cartesian coordinates measuring method to measure the components’surface profile precisely.

Major application industry
The contour measurement of photovoltaic guide wheel, large machinery such as large plastic machine, machine tools, keys parts of transmission shaft, large precise lead screw.
