Do You Need to Measure CNC, Milled and Ground Shafts

Estimated reading time 2 minutes

The latest release of the MarShaft Scope 250 plus is designed for the optical quality assurance of small rotationally symmetrical workpieces and builds on the success of previous models.

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, and in the workshop, is essential with rapid feedback to the manufacturing process to avoid waste. Mahr’s flexible MarShaft SCOPE 250 plus shaft measuring machine 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 and a vertical measuring axis with a measuring range of 250 mm, a measuring diameter of 40mm. At its heart is the state-of-the-art, high-resolution CMOS matrix camera (live image) with an image field of 1088 x 2048 mm. 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.

The performance figures are also impressive with a length/diameter resolution of 0.01…0.0001mm, an angle resolution of (°) 0.01…0.0001with a length error limit (Z) of (µm) ≤ (3.0+l/125) L in mm and a Diameter error limit (X) (µm of ≤ (1.5+l/40) L in mm

The measuring station is designed for the smart factory of Industry 4.0: Measurements are fully automated, and workpieces can optionally be recognized via the barcode reader.
