Product News: Surface Roughness Measurement Option for MarForm MMQ 200

Reduces setup time and testing costs

Published: Wednesday, July 21, 2010 - 18:17

(Mahr Federal: Providence, RI) -- Mahr Federal Inc. has introduced a new option package for its well-known MarForm MMQ 200 Formtester, which provides the measurement of surface finish parameters according to accepted standards from the International Organization for Standardization (ISO) and  the American Society of Mechanical Engineers (ASME), plus Japanese Industrial Standards (JIS) from the Japanese Standards Association (JAS). With the combined hardware/software MMQ 200 Surface Finish option, operators will benefit from reduced setup and measurement cycle time, and reduced cost by needing only a single piece of equipment for form and surface measurements.

“The key to providing accurate surface finish data with a form machine is high resolution and low residual noise,” says Pat Nugent, vice president of metrology systems for Mahr Federal. “Unlike many form measurement machines that are designed to measure longer wavelengths and allow five to 10 microns between data points, the controller for the MMQ 200 was designed with roughness measurements in mind. It can sample data with spacing down to 0.5 microns, well within accepted international standards for roughness measurement.”

The roughness option package for the MMQ 200 utilizes 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 motorized T7W probe head. The MMQ 200 automatically swivels the probe to apply the diamond stylus, and changes from horizontal to vertical measurement as needed, utilizing standard surface finish parameter cutoff lengths. A skidless probe measuring option is also available.

Optimized for measuring cylindricity and other deviations of form and position, the MMQ 200 Formtester comes with Mahr’s newest EasyForm v. 3 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 new hardware/software package is available as an option and includes Mahr’s Advanced Form software for creating automated solutions for the most demanding applications.

This ease of operation makes the MMQ 200 ideal for use by machine operators right in production areas where immediate measurements can minimize scrap, save time, and reduce production costs. Optimized for the measure of cylindricity through rotational table axis and vertical axis integration, the the MMQ 200 can also perform a full range of ISO 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).

“For many applications, the ability to take surface and form measurements with a single setup can reduce costs and speed the overall measurement process without sacrificing measurement quality,” Nugent says.
