MMQ 400-2 Formtester Redesigned with Surface Finish Capability

Dramatically increased speed and resolution, measures surface finish to ISO, ASME, JIS standards

Published: Tuesday, August 2, 2011 - 15:29

(Mahr Federal: Providence, RI) -- Mahr Federal Inc., designer, manufacturer, and marketer of dimensional measuring technology, will be featuring the new version of its successful MMQ 400 Formtester series, the MarForm MMQ 400-2, at Quality Expo 2011, Sept. 20–22, 2011, at McCormick Place North, in Chicago. Mahr Federal will occupy booth No. 600.

The MarForm MMQ 400-2 integrates a new controller that allows the measurement of surface finish parameters according to standards from the International Organization for Standardization (ISO), the American Society of Mechanical Engineers (ASME), and Japanese Industrial Standards (JIS). With dramatically increased speed and resolution, the MMQ400-2 samples data with spacing as tight as 0.005 microns. Benefits include reduced setup and cycle times, and cost savings from using a single system for both form and surface measurements.

The MarForm MMQ 400-2 Formtester was a ground-up redesign and delivers a machine that is more robust, less sensitive to environmental influences, faster, more flexible, and more accurate than comparable systems. The MMQ 400-2 offers an impressive array of features, including extremely solid construction with a generously dimensioned, reinforced steel base. High-precision mechanical bearings for the rotary table eliminate the need for an air supply, and all motors and electronic components have been thermally isolated to enhance stability. Wherever possible, homogeneous materials have been used in construction to minimize the effects of thermal expansion.

The skidded probe roughness package for the MMQ 400-2 utilizes the same 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 400-2’s motorized T7W probe head. The MMQ 400-2 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 utilizing diamond-tipped styli that are directly mounted to the T7W probe head.

Several versions of the MMQ 400-2 Formtester are available. Options include manual or motorized center and tilt tables; vertical Z-axis length of 350 mm, 500 mm, or 900 mm for long shafts; and horizontal X-axis of 180 mm or 280 mm. All measuring axes are fully motorized. A selection of available probes—including the T7W 360° motorized bidirectional probe, and the manual T20W probe—further enhances measuring flexibility.

Also on display at Mahr Federal’s booth at Quality Expo will be the new MarCheck measuring and evaluation unit for Mahr’s high-precision Linear 100 universal length measuring instrument, the new generation of MarCal digital calipers, and the new Digimar 816 CL Height Gage, along with a full range of other Mahr Federal handheld gauges and other dimensional metrology products.
