GRINDING WITH ABRASIVE
The workpieces to be deburred are placed in circular vibrating tanks or in the barrels of the sieves as for the previous operation, but with the addition of ceramic abrasives and liquids. Is used to remove the coarser burrs and in cases where it is required a rounding, more or less marked, of the edges.
Is performed in the tanks vibrating with the addition of corn sawdust and polishing pastes. In the presence of heavily dirty surfaces it may be required to perform firstly a fast debarring cycle with abrasives with the aim to clean the surfaces with greater energy. It is not possible to polish pieces that tangle up each other
