Ease of operation makes Mahr Federal's 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 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).

Key features of the MMQ 200 include: three motorized axes, with both measuring axes (C and Z) optimized for high precision; computer and graphic-assisted test piece alignment on the manual tilting and centering table; universal T20W test probe with a 2 mm working range, stroke limitation, and mechanical probe zenith setting for high-precision measurements; EasyForm measuring, control and evaluation software; a Pentium-class PC using Windows XP Professional; and a 15" touch-screen monitor.

Like the other members of the MMQ family, the MMQ 200 requires no outside air supply. The high-precision mechanical bearings used in the rotary table are more accurate than most air bearings and up to 70 times stiffer, making the system less susceptible to external forces such as vibration which is critical for operation in real world production environments.
