Versions
MarForm MMQ 400-2 is available as a partially automatic measuring station with manual centering and tilting table or as a fully automatic measuring station which, in conjunction with the motorized centering and tilting table and the T7W probe, is perfectly designed for the task of precision testing your parts with no operator intervention.
The T7W measuring probe has a motorized rotational axis which allows you to move the probe gradually into any desired contacting position. It can be used for measurements on both cylindrical surfaces and end faces. In addition, as a zero position probe, the T7W can also switch between inner and outer measurements or between top and bottom end face measurements automatically, without operator intervention. Fully automatic measuring sequences on complex workpieces can be performed without operator intervention. The T7W probe arms are interchangeable. With its motorized rotational axis you can also create multi-point probe arms, i.e. probe arms with multiple contact elements, allowing you to switch between different stylus ball geometries within a measuring run.
Combine the checking of form and position tolerances with the monitoring of roughness parameters. Document typical roughness parameters such as Ra and Rz while form testing your workpieces with a MarForm MMQ 400-2, without having to reclamp the workpiece at a different measuring station. This is achieved with a motorized, program-controlled switching between the form probe with ruby ball and the roughness probe PHT 6-350. No operator intervention is required, and the relevant probe is moved automatically from vertical contact to a horizontal position. This is done using the motorized rotational axis of the T7W form tester, which positions the probe in 1° increments.
