Measurement Machine Quickly Images Turned Parts

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

The machine also delivers fast speeds using a high-resolution CMOS-matrix camera with a live image field of view of 40 × 24 mm, enabling it to capture an entire part diameter in a single view. With Z-axis positioning speeds ranging to 200 mm/sec. and an image acquisition rate of over 120 images per second, measurements can be performed faster than the blink of an eye, according to the company. Zoom functions enable measurement of small details such as chamfers and radii, which can be difficult to test with conventional measuring methods.

The MarShaft Scope 250 Plus can be operated entirely on the integrated touchscreen or using a keyboard and mouse. MarWin-based EasyShaft software enables the precision measurement of diameters, lengths, contour features, and form and position tolerances in accordance with standards, and offers other evaluation and documentation options. The touchscreen provides direct access to positioning, programming, measurement and documentation, including the use of swipe functions.
