Pollution control equipments manufactures hydro-honing blast cleaning machines for cleaning and finishing delicate components without effecting tolerances. In the hydro honing process, fine abrasives, like alumina oxide, silicon carbide, glass beads, etc, are mixed ni water and are thrust on the job at high velocity. Dur to impact of abrasive particles, jobs get cleaned. Surface finish depends upon the mesh size of abrasive aprticles, finer the abrasive smoother will be the surface finish. And the machines are most suitable for cleaning heat treated components, machined parts, maintenance cleaning of pistons, valves and engine components, etc.
