The Different Between Slit Edge And Mill Edge
Leave a message
The terms "slit edge" and "mill edge" are often used in the context of metal sheet and coil processing. These terms refer to the edges of metal sheets or coils after they have undergone specific manufacturing processes. Here's a brief explanation of the differences between slit edge and mill edge:
Mill Edge:
Definition: Mill edge refers to the original edge of the metal as it comes from the rolling mill.
Appearance: The mill edge is often rough and may have burrs or irregularities due to the rolling process.
Processing: The metal sheet or coil is produced by passing it through a rolling mill, and the edges are not further processed after this initial manufacturing step.
Applications: Mill edge sheets or coils are often used in applications where a finished edge is not critical, such as when the material will be further processed, or the appearance of the edge is not a primary concern.
Slit Edge:
Definition: Slit edge refers to the processed edge of metal sheets or coils after they have been slit into narrower widths.
Appearance: The slit edge is generally smoother and more uniform than the mill edge. Slitting removes the irregularities and burrs present in the mill edge.
Processing: Slitting is a cutting process that involves cutting a wide coil into narrower strips. The edges of the strips are then typically deburred to produce a clean, smooth slit edge.
Applications: Slit edge sheets or coils are preferred in applications where a clean, finished edge is important. This is common in industries where the material will be used directly without further processing, and a neat appearance is desirable.
