Engineer demonstrating MarShaft

The latest release of the MarShaft Scope 250 plus, available in the UK from Market Harborough-based Optimax IIM Ltd 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), 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. It has a high precision roundness measuring axis and a vertical measuring axis with a measuring range of 250mm, and a measuring diameter of 40mm.

At its heart is the ‘state of the art’, high-resolution CMOS matrix camera providing a live image with an image field of 1,088 x 2,048mm. 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 measuring station is designed for Industry 4.0 — measurements are fully automated, and workpieces can optionally be recognised via the barcode reader.
