MarShaft SCOPE 250 plus

The role of dimensional metrology is expanding at a dramatic rate, in parallel with innovations in manufacturing processes. Given the ever more stringent accuracy requirements and falling cycle times in production (turning, milling, grinding, etc.), rapid measurement directly at the manufacturing machine is absolutely essential. Measurement at the point of origin of the product, with rapid feedback to the manufacturing process to avoid waste. Mahr’s flexible MarShaft SCOPE 250 plus shaft measuring device offers the right measuring solution for the fast, precise and fully automatic measurement of rotationally symmetrical workpieces in production.

The MarShaft SCOPE 250 plus has a high precision roundness measuring axis (C) and a vertical measuring axis (Z) with a measuring range of 250 mm. At its heart is the state-of-the-art, high-resolution CMOS matrix camera with an image field of 1088 x 2048 mm (live image). The extremely high image acquisition rate of over 120 images per second keeps measuring times to a minimum. Zoom functions allow the smallest details to be measured, which with conventional measuring methods are difficult if not impossible to test.

Optical shaft measuring station MarShaft SCOPE 250 plus can be utilized in large industrial enterprises just as effectively as in small workshops. Production companies use it to test the production quality of smaller rotationally symmetrical workpieces. The measuring system is designed for testpieces with a diameter of up to 40 mm and a maximum length of 250 mm, such as precision turned parts, bone screws, or medical glass bottles.
