Mahr’s new option package for its Marform MMQ 200 Formtester enables the measurement of surface-finish parameters according to accepted ISO, ASME and JIS standards.

The combined hardware/software MMQ 200 surface-finish option reduces setup and measurement cycle times while reducing the overall cost of both form and surface measurement, as only a single piece of equipment is required.

Brett Green, managing director at Mahr UK, 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 have been designed to measure longer wavelengths and allow five to 10 microns between data points, the control system of the MMQ 200 has been designed with roughness measurement in mind.

‘It can sample data with spacing down to 0.5 microns, which is well within accepted international standards for roughness measurements,’ he added.

The key to this combined measurement capability is the company’s automated probe system, with the T7W motorised bidirectional probe allowing in-cycle automatic switching between the form and surface styli.

The roughness option package utilises the same skidded diamond-tipped PHT stylus as the one used on Mahr’s PS1 and M300 surface-finish measuring machines and the same Marwin-based surface-finish software as in the company’s Marsurf XR 20 contour measurement system.

The roughness stylus is mounted opposite the ruby-tipped form probe on the T7W probe head, with the MMQ 200 automatically swivelling the probe to apply the diamond stylus.

It 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 as standard with Mahr’s latest Easyform software.

It is compact and fast and can be used in the metrology laboratory or on the shop floor.

The new hardware/software option package for surface roughness measurement includes Mahr’s Advanced Form software for creating automated solutions for demanding applications.

The MMQ 200 is ideal for use by machine operators in production areas where immediate measurements can minimise scrap, save time and reduce production costs.

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

Green continued: ‘For many applications, the ability to take surface and form measurements with a single setup can reduce costs and speed up the overall measurement process without sacrificing measurement quality.

‘The new surface roughness measurement option is now being extended to other instruments in the MMQ Formtester range, including the popular MMQ 400 Formtester shown at the recent Control Show in Stuttgart,’ he said.
