When selecting or designing a disk knife, several dimensions are critical to ensure compatibility with the slitting machine:
Outer Diameter (OD): Determines the depth of cut and the speed of the blade edge.
Bore/Arbor Hole: The center hole size must match the machine's drive shaft perfectly to avoid "run-out" (vibration).
Thickness: Thinner blades create less waste, but thicker blades are more stable under high lateral pressure.
Bevel Angle: Single Bevel: Sharpest edge, used for soft materials.
Double Bevel: Stronger edge, used for tougher materials to prevent chipping.
