MarForm MMQ 400 Formtester

Nov. 14, 2006
Mahr's universal form measuring machine measures roughness, waviness, and contour measurements, among others.

The MarForm MMQ 400 Formtester features optimized mechanical components in CAD with Finite Element Methods 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 MMQ 400 can measure parts up to 132 lb. (60 kg) and eliminates the need for an air supply by the use of a high-precision mechanical bearing for the rotary table. Two versions of the MMQ 400 Formtester are available, one with a 14-in. (350 mm) Z-axis and 7-in. (180 mm) X-axis, and the other with a 20-in. (500 mm) Z-axis and 11-in. (280 mm) X-axis.

 

Fully controlled by Mahr MarWin software, the MMQ 400 can evaluate all standard form parameters, including roundness, sector roundness, run-out, sector run-out, concentricity and coaxiality, total run-out, cylindricity, straightness, section-by-section straightness, parallelism, perpendicularity, angularity, flatness, conicity, and taper. The system has been specially designed to measure a wide variety of workpieces, including injection components, ABS components, valves, pistons and piston rods, crank and camshafts, brake disks, gear shafts, ball bearings, and more.

  • Can be used universally for workpiece assessment per DIN ISO 1101
  • High-precision measuring axes in Z and X make every form measuring task possible
  • Motorized or manual centering and tilting table
  • Vertical axis (Z) with a 35 (900), 20 (500) or 14 in. (350 mm) length
  • Horizontal axis (X) with a 7 (180) or 11 in. (280 mm) length and with digital linear scales in axes X and Z
  • Optional motorized tailstock for shafts from 8 in. (200 mm) long
