The processing will enable you to miniaturize the parts which were given up because of minute burrs. Amazing deburring technique!

SEP treatment will enable deburring at inlet/outlet of fine pore, polishing/extension of inner diameter. 　Do you have any trouble like ... 　 *You can't receive the order because it is difficult to remove burr at many fine pores. 　 *You give up because you can't control roughness of inner diameter. 　Please try SEP treatment! 　For example, if apply deburring by electrolytic polishing or fluid polishing to the product below... 　 　・There are many pores remaining burrs. 　　・The edge becomes round. 　　　・Pore size becomes uneven. 　SEP treatment will realize 　 　deburring　＋　improving surface roughness　＋　rinsing　 　　　　　　 　　　　at the same time. Reference Cross Section Picture before SEP after SEP It looks rough on the whole and less reflective. It looks smoother than before SEP treatment, and more reflective. *　microscope by KEYENCE x 1000 Edge is kept sharp *After SEP, Edge part SEP treatment enables to control variation of inner diameter uniformly, and improve surface roughness to less than 0.1. before SEP after SEP roundness : 5μ roundness : 1.3μ Burr has been removed. Both roundness and diameter are within the specification.
