✔ Hammering the surface by pin media -> Make the surface strong
✔ Can polish & clean inside of cylinder design & small space
✔ Minimize material “Loss” by Hand‐Polish with 3D Tumbling Barrel -> improve 9% ~ 11% to less than 5%
✔ Help to clean the investment powder on the casting
✔ Help to remove the oxidized casting surface
✔ No POISON -> can switch from “Electro‐polishing with cyanide”
These electro-magnetic barrel finishing machines are used for finishing small material and non-metallic parts.
Work pieces and magnetic media are put in a machine. The tumbling motion by a strong alternating magnetic field induced electrically makes the work pieces surface shiny in a short time.
The work pieces regardless of their number, receive the same uniform finish. Even work pieces with complicated shapes can be finished uniformly to get the same glossy surface. Very small burrs are removed and beveling is made slightly.
When the magnetic barrel media are repeatedly subjected to the large kinetic tumbling energy in the stronf alternating magnetic field, they smooth the work piece surface effectively by numerous collisions.
These machines are ideal for finishing precious metal lost wax casting. Bulky work pieces can be finished. Ceramics and plastics can also be processed using the appropriate abrasives and barrel media.
Using no abrasives, this stainless steel pins and small balls give the work pieces beautiful surface finish with very little loss of material. This is called shot peening and varnishing effect.
