Castings produced by metal casting machinery undergo several common finishing processes to ensure they meet desired specifications and are suitable for their intended applications. One of these processes is machining, which utilizes cutting tools to remove excess material and achieve the desired shape and dimensions of the casting. Depending on the complexity of the casting, machining can be carried out manually or using computer numerical control (CNC) machines.
Grinding is another widely used finishing process that eliminates any surface irregularities or imperfections left after the casting process. Abrasive wheels or belts are employed in grinding to achieve a smooth and uniform surface finish.
To enhance appearance and protect against corrosion, surface treatment processes are commonly employed. Sandblasting, involving high-speed particles to clean and roughen the surface, and shot blasting, using high-velocity steel shots to remove burrs and improve surface quality, are examples of surface treatment methods.
Additionally, castings may undergo processes such as polishing, buffing, or lapping to acquire a high-quality surface finish. These procedures employ abrasive compounds or polishing wheels to eliminate any remaining imperfections and create a smooth and shiny surface.
In some cases, heat treatment processes are necessary to enhance the mechanical properties of the castings. Heat treatment methods like annealing, tempering, or quenching are utilized to modify the hardness, strength, and ductility of the castings.
In conclusion, the common finishing processes for castings produced by metal casting machinery include machining, grinding, surface treatment, polishing, heat treatment, and others. These processes are vital for achieving the desired shape, dimensions, surface finish, and mechanical properties of the castings.
