Easy measurement of cylindricity

Equipped with the latest generation EasyForm software, Mahr's new Marform MMQ 200 Formtester takes ease-of-use to a new level when measuring cylindricity and other elements of form and position.

In either the production or metrology environment the MMQ 200, which is optimised for the measurement of cylindricity through rotational table (C) axis and vertical (Z) axis integration, can perform a full range of form checks, including roundness, straightness, flatness, parallelism, conicity, concentricity, run-out, taper, perpendicularity, angularity and angle sector (ie roundness, flatness, run-out). Having a measuring envelope of 380 mm (height) by 210 mm (diameter), roundness deviation is 0.015 mm + 0.0003 mm per mm measuring height, and 0.02 mm + 0.0003 mm per mm measuring radius. And there's computer and graphic-assisted test piece alignment of the manual tilting and centering table that holds the 100 mm diameter rim chuck. The two high-precision measurement axes (C/Z) and the horizontal positioning axis (X) are motorised, as is the T7W probe offered as an alternative to the universal T20W manual probe. The T7W offers complete automation regarding probe positioning, and the system allows flexibility over 360º, eliminates operator error and speeds up the measurement routine. Up to 32 measuring routines can be saved for automatic operation via programmable function keys, enabling a roundness measurement, for example, to be completed in two simple steps. Measurements are displayed immediately on the LCD screen display, with options including 3D representation with colour or grid lines providing an interactive graphical preview. Results can be printed, saved in file formats such as PDF or exported for analysis in other software packages. It can be operated either by the optional touch screen or via the keypad built into the machine base, and there is no requirement to learn a programming language. The intuitive user interface of the EasyForm Version 3 software, guides the user through the measurement set-up and process, with the teach-in mode remembering every step taken.
