Edge Treatment (Round edge, Debarred edge)

Overview & Features

Edge treatment is a further processing applied to the normal Slit Edge^※1 and can be delivered with "Debarred Edge"^※2 to remove burrs or "Round Edge"^※3 to round the edge.
This process enables applications where the material width and edge are used as is.
Smoothing the edge also prevents fatigue failure from the width direction, leading to improved spring durability.
※1　Slit Edge: Slitting only (standard specs)
※2　Mill Edge: Removing burrs generated by slitting with file
※3　Round Edge: Processing burrs generated by slitting as well as the shear drop side.
　　(You can choose between arc-shaped rounded edges or rounded corners.)
