Calibrating & Tolerance Grinding

With the correct abrasive mineral, travelling at the correct speed, with the correct pressure, and there is enough power to do the job, on a robust enough machine with a sophisticated control system to monitor and maintain the process, high stock removal rates of hard material, to extraordinarily tight tolerances (0.05mm over slabs of 2000x11000mm) can be achieved and maintained. Sanding paper has come a long way, and few people realise just how far.
