The Marform MMQ 400-2 from Mahr Federal adds surface finish capability and is faster, provides higher resolution on all axes, and features improved electronic interface compared to the previous version. A new controller increases machine speed and resolution and allows the machine to measure surface finish characteristics according to ISO, ASME, and JIS standards. The system can sample data with spacing as tight as 0.005 μm. The tester can evaluate 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. It can measure workpieces such as injection components, ABS components, valves, pistons and piston rods, brake disks, gear shafts, and ball bearings. The skidded probe roughness package uses a diamond-tipped PHT stylus, which is mounted opposite the ruby-tipped form probe on the motorized probe head. The probe automatically swivels to apply the diamond stylus and changes from horizontal to vertical measurement as needed. Versions include manual or motorized center and tilt tables; vertical Z-axis length of 350, 500, or 900 mm for long shafts; and horizontal X-axis of 180 or 280 mm.
