Dial indicator test device for quick testing of dial indicators and simple operation of testing of dial indicators or precision dial comparators. A powerful camera takes over the stressful error-prone reading of the displayed values. The associated software controls the test device for you and checks that the data readings match the specified reference values.

The Precimar is the most cost effective test station for manual testing of digital and dial indicators, dial test indicator measuring devices as well as inductive and incremental measuring probes.

Technical innovation and quality-oriented thinking are the core competencies of successful businesses.

Both competencies are not possible without metrology.

Measurement instruments verify research and development results and document product quality. Without continuous advancement of metrology there would be no technical progress.

Mahr offers a wide range of measuring instruments to solve your specific measuring task. Convince yourself!

Prism – Residual stress measurement based on hole-drilling and ESPI Prism is an advanced hole-drilling system that dramatically improves the ability to make quick and accurate residual stress measurements. Just like the conventional strain gage hole-drilling systems, the instrument measures changes in the part surface caused by the hole drilling and determines the previously existing residual stresses. However, the often time-consuming application of strain gages is avoided and a large area around the hole is analyzed, not averages from just a few areas. Prism measures surface distortion using electronic speckle pattern interferometry (ESPI). Only minimal sample preparation is required. The update of the coefficient data set in 2015 has significantly improved the quality of the stress results. This also increases the relative depth from which reasonable results can be expected.

X-RAY DIFFRACTION is the conventional and time proven technique for measuring residual stresses. Using the interatomic spacing as the ultimate gage length, the X-ray technique is ideal for and applicable to all crystalline materials, especially for metals, but also for ceramics. It measures the absolute stress without the need for an unstressed sample for calibration.

Stresstech Group’s Xstress 3000 G2/G2R represents advances in design and construction, which provide enhanced reliability and function in the first truly portable X-ray stress analyzer.

STUDER conventional cylindrical grinding machines are designed for the grinding of workpieces in individual as well as small and large series production operations.

The S20 is designed for grinding medium-sized workpieces in individual and batch production. It is suitable for use in any industry where precise small components are manufactured. Operation is very simple and the machine can be reset very quickly.

The S30 is designed for grinding workpieces in individual and small batch production. It is suitable for use in any industry where precise medium-sized workpieces are manufactured. Operation is very simple and the machine can be reset very quickly.

The Studer S11 production cylindrical grinding machine is the youngest S11 and the smallest machine in the company’s portfolio and is tailor-made for workpieces up to 200 mm in length.

If space-saving is your priority, then the S11 is the right machine for you. In a space of less than 1.8 m² the S11 produces extremely efficiently and reliably with a grinding wheel diameter 500 mm.
