Surface Roughness Measurement Option for MarForm MMQ 200

A single piece of equipment for both form and surface measurements reduces set-up and measurement-cycle time

Published: Monday, February 7, 2011 - 15:12

(Mahr Federal: Providence, RI) -- Mahr Federal will be featuring the new option package for their well-known MarForm MMQ 200 Formtester at Design & Manufacturing South, March 16–17, at the Orange County Convention Center in Orlando, Florida. Mahr Federal will occupy booth No. 1021.

The new option package for the MarForm MMQ 200 Formtester provides the measurement of surface finish parameters according to accepted standards from the International Organization for Standardization (ISO), the American Society for Mechanical Engineers (ASME), and the Japanese Industrial Standards Committee (JIS). With the combined hardware/software MMQ 200 Surface Finish option, operators will benefit from reduced set-up and measurement-cycle time, and reduced cost, needing only a single piece of equipment for both form and surface measurements.

The MMQ 200 was designed with roughness measurements in mind and can sample data with spacing down to 0.5 microns, well within accepted international standards for roughness measurement. The roughness option package 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 cut-off lengths. A skidless probe measuring option is also available.

Also on display at Mahr Federal’s booth No. 1021:

• The new MarCheck measuring and evaluation unit for Mahr’s high precision Linear 100 universal length measuring instrument. MarCheck allows both measurements and calibrations to be performed quickly and reliably at the touch of a button.
• A new generation of its popular line of MarCal digital calipers. Included are a number of innovations, such as lapped guide ways, a new reference system which retains the zero position setting, and an increased number of product options and accessories.
• The new Digimar 816 CL Height Gage, which provides highly accurate measurements without complicated procedures. Its robust design and user-friendly operation combine with advanced features and functionality to improve dimensional measurement on the shop floor or in the lab.


A full range of other Mahr Federal handheld gauges and other dimensional metrology products will also be on display.
