A new technology that can cleanly remove fine burrs and edges.
S.E.P processing is a new technology that allows for the clean removal of fine burrs and edges, which can change surface roughness and eliminate burrs, by immersing products in a special liquid. (Features) ● It can uniformly polish complex shapes (grooves, holes) that are difficult to finish with barrel finishing. ● There is almost no occurrence of deformation, distortion, or dents in thin workpieces. ● It removes fine cracks and irregularities on the surface of parts, smoothing them out, which reduces the coefficient of friction and improves the lifespan and durability of the parts. ● Due to improved surface roughness of metals, parts become less prone to rust. ● Dimensional changes before and after processing can be managed in micrometers. ● It does not affect the metal structure of the parts, so there is no concern about the occurrence of brittleness. (Materials that can be processed) Low carbon steel: SS, SPC, SPH, equivalent to S15C High carbon steel: SK, SKS, equivalent to S45C, SCM, SCR, SUJ SUS steel: SUS304, SUS316, SUS420, SUS630, etc. Tool steel: SKD, SKH Others: Copper and copper alloys, aluminum and aluminum alloys, nickel, cobalt, titanium, etc., general metals.

basic information
S.E.P processing is a new technology that allows for the clean removal of fine burrs and edges, which can change surface roughness and remove burrs that are difficult to eliminate through traditional methods, by immersing products in a special liquid. (Features) ● It can uniformly polish complex shapes (grooves, holes) that are difficult to finish with barrel processing. ● There is almost no occurrence of deformation, distortion, or dents in thin workpieces. ● It removes fine cracks and unevenness on the surface of parts, resulting in a reduced friction coefficient, which improves the lifespan and durability of the components. ● Due to improved surface roughness of metals, parts become less prone to rust. ● Dimensional changes before and after processing can be managed in micrometers. ● It does not affect the metal structure of the parts, and there is no concern about the occurrence of brittleness.
