    Grinding and Polishing Guide Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen Grinding, sanding, polishing, deburring FerRobotics,Automated grinding, sanding and polishing instead of costly manual work processes the Active Orbital Kit 601 is the perfect tool for surface treatment of large surfaces like railway cars, busses, planes or ship bodies. The integrated complete solution automates the industrial sanding process with individual control of all process parameters.
