The wet grinding process occurs when a product is transformed from solid to liquid, regardless of its viscosity: paints, inks, enamels, nail varnish, among others. In this process, agglomerates that were not separated in the dispersion phase (due to the electro-physical bonding of some components) are broken by applying extra energy.. This wet …

Thread: holding small flat brass parts for surface grinding. Nitro works better than acetone to dissolve CA, but it's still pretty slow. Heat is probably the fastest if your parts can stand it. CA generally melts at a little over 300° F. To grind non-magnetic parts directly on the magnet I like to use a hot glue gun.
