Optical Systems for Shopfloor Shaft Measurement

Mahr Federal features the MarShaft Scope 250 Plus and the MarShaft Scope 600 Plus 3D. The MarShaft Scope 250 plus flexible optical system is designed to provide fast, accurate, fully automatic measurement of smaller shafts and turned parts directly on the shop floor, featuring a matrix camera with 4 million pixels. The system measures parts ranging to 250 mm in length and 40 mm in diameter and has a maximum permissible error of less than 1.5 microns + L/40 when measuring diameter and 3 microns + L/125 when measuring length.

Combining optical and touch sensors in the same unit, the MarShaft SCOPE 600 Plus provides 3D functionality and complete inspection of the workpiece in a single measurement. Its matrix camera optically measures characteristics such as diameter, length, radius, shape, location characteristics, and so on, in seconds, while a 2D sensor detects features that are not optically measurable, such as cam lift on concave cam profiles and reference (clocking) features such as holes or keyways.
