Mahr Federal has introduced an option package for its Marform MMQ 200 Formtester that provides the measurement of surface-finish parameters according to accepted ISO, ASME and JIS standards.

With the combined hardware/software MMQ 200 Surface Finish option, operators will benefit from reduced set-up and measurement cycle time and reduced cost by needing only a single piece of equipment for both form and surface measurements.

Pat Nugent, vice-president metrology systems for Mahr Federal, said: ‘The key to providing accurate surface-finish data with a form machine is high resolution and low residual noise.

‘Unlike many form measurement machines that are designed to measure longer wavelengths and allow 5-10microns between data points, the controller for the MMQ 200 was designed with roughness measurements in mind.

‘It can sample data with spacing down to 0.5microns, well within accepted international standards for roughness measurement,’ Nugent added.

The roughness option package for the MMQ 200 utilises the same skidded diamond-tipped PHT stylus as is used on Mahr Federal’s PS1 and M300 surface-finish machines, and the same Marwin-based surface-finish software as the Marsurf XR 20.

The stylus is mounted opposite the ruby-tipped form probe on the MMQ 200’s motorised T7W probe head.

The MMQ 200 automatically swivels the probe to apply the diamond stylus, and changes from horizontal to vertical measurement as needed, utilising standard surface-finish parameter cut-off lengths.

A skid-less probe measuring option is also available.

Optimised for measuring cylindricity and other deviations of form and position, the MMQ 200 Formtester comes standard with Mahr’s Easyform v3 software.

The MMQ 200 is compact, fast, easy to learn and operate, and is equally at home in the metrology lab or on the shop floor.

The hardware/software package for surface roughness measurement is available as an option and also includes Mahr’s Advanced Form software for creating automated solutions for even the most demanding applications.

This ease of operation is said to make the MMQ 200 ideal for use by machine operators in production areas where immediate measurements can minimise scrap, save time and reduce production costs.

Optimised for the measure of cylindricity through rotational table axis and vertical axis integration, the MMQ 200 can also perform a full range of ISO and/or ASME form checks, including: roundness, straightness, flatness (from a polar trace), parallelism, concentricity, coaxiality, run-out, total run-out, taper, perpendicularity, angularity, and angle sector (roundness, flatness, run-out).
