MarShaft Scope 25: For the reliable testing of small turned parts  

Smaller measuring systems suffice for the quality assurance of small shafts. Applications specialist Mahr now offers the new low-cost shaft measuring instrument "MarShaft Scope 25" for this application: This optical measuring station allows you to automatically and contactlessly check the diameter, length and radial run-out of small turned parts directly in production. Advantages for the user: Saves time in measurements and the investment quickly pays for itself.

Mahr's "MarShaft Scope 25" is an optical shaft measuring instrument for small, rotationally symmetrical workpieces – for example turned parts, plug connections and precision parts. Production plants can check all the relevant features of workpieces of up to 200 mm (7.87 in) in length and 25 mm (0.98 in) in diameter at the measuring station. Measurements can be performed quickly in just a few steps: The user clamps the workpiece between the two centering pins and quickly finds the relevant measuring positions in a shadow image. He then starts the automatic measurement by the line scanning camera via the measuring computer. The main advantage of this automated quality assurance is that the user cannot influence or accidentally distort the measuring results.

The "MarShaft Scope 25" offers high precision thanks to the intelligent combination of various measuring sensors such as a profile projector and measuring microscope. For example, the measuring accuracy for diameter measurements is 1.5 µm + L/100 and 6 µm + L/100 for length measurements. Workpieces are measured two-dimensionally by two sensors at 7.5 ° angles (diode cells). The measuring programs for the individual workpieces can be created and saved on the measuring computer in just a few minutes.

The attractive, state-of-the-art low-cost instrument is designed for harsh manufacturing environments. It compensates for temperature differences and vibrations, thus providing reliable measuring certainty. A setting master is integrated for fast and reliable calibration. The "MarShaft Scope 25" comes with a measuring computer and evaluation software.
