Non-contact scanning of turned parts is rapid, accurate

Turned parts can easily be measured with the MarScope non-contact universal measurement system from the Mahr Group.

The MarScope is ideal for any cylindrically symmetrical part and can measure general features, such as diameter, lengths and widths. With its precision rotary stage, it can also measure a variety of geometric tolerances, such as roundness and run-out. Additionally, due to the high resolution CMOS matrix camera, measurement of small features, such as radii and chamfers, can be carried out automatically and to a higher to degree of accuracy than previously possible. Once the program routine is initiated, the camera will scan the part, collecting millions of data points every second. Within moments of scanning the part, all characteristics are displayed and compared to their nominal values or tolerance limits. MarScope systems are available in a range of sizes and configurations. Parts up to 1 m in length can be measured, while the rotary stage can handle components up to 120 mm in diameter and weighing up to 30 kg. The Mahr Group has 150 years of metrology experience, with combined knowledge of both non-contact and tactile measurement principles, allowing it to produce what is now the market leader in non-contact shaft measurement. To complement the standard MarScope systems, Mahr also offers options - including tactile probing, thread measurement software and application programming - to help solve yet more challenging applications. The Mahr Group is the third largest metrology company in the world and employs over 2,000 people. Other product lines include surface finish measurement systems, form testing, gear metrology and a wide variety of precision gauges.
