It is extremely important to know the conditions of wheel working face for managing grinding processes. Among the conditions, wear flats and their arrangements are critical because they directly have an influence on the integrity of the surface ground. However, conventional methods or apparatuses are not necessarily sufficient for measuring them as their measuring speeds or resolutions are lower than those required in practical grinding. This paper describes a system for managing grinding processes using high-speed visualization of a wheel working face at a 30m/s practical wheel peripheral speed. Images obtained by this system are almost the same quality as ones obtained by a microscope. The spatial resolution of this system is 6μm. The background, or part lower than the active cutting edges, can also be erased with a precision of about 50μm using a masking technique based on the height data of them.
