A slitter machine can make all the difference when close tolerances are necessary for your project. But how do these machines achieve such close tolerances?

First, let’s start with a basic definition: A slitter produces narrow widths from wider sheet by means of rotary knives. This process is used to make edges straight and can also be used on both ferrous and nonferrous materials. Additionally, while slitting is used well for both sheet and coil rolls, it is restricted to only cutting thin materials.

Now, let’s take a step-by-step look and how that process gets done:

Step One 

Coil is moved to the uncoiler, set accordingly to slit the desired width, and then uncoiled by being fed into the machine length wise. As material is being fed through, it is simultaneously cut by the sharp circular upper and lower blades.


Step Two

Quality checks are performed on the slitted material, and thin metal discs called separators are used to guide slitted material to the recoiler.


Step Three

At the recoiler, the slit material is placed between the separator’s upper and lower arms and then recoiled.


Step Four

The cuts are taken, banded, and then stacked on skids, ready to be shrink wrapped, packaged, and shipped.
