Generally, forgings and castings tend to have a rough surface finish and a dull appearance. Manual finishing is time consuming and does not deliver consistent results.
ActOn engineers recommend using vibratory finishing or high energy finishing machines to achieve a smooth surface and a polished finish. Over the years, we have developed and optimised processes on various forgings and castings with different finishing specifications, such as the removal of surface defects and flash lines or achieving a surface finish of Ra 0.03 μm.
The finish has been achieved by carrying out a two-stage process in ActOn's high energy finishing machine. To remove the machining lines the part was processed in Aluminium Oxide and compound. This media was used as it has the properties which allow to deburr parts made from hard metals and sintered carbide. The final stage was carried out using
pre-treated agro media which is great for producing a bright finish.
