Slitting Machine
Performance Is Defined by Tooling Accuracy
How slitter knives, spacers, and rolls control cut quality and repeatability.
The Core of Coil Processing
A slitting machine operates as a high-precision production line, transforming master coils into narrower strips. The integrity of the final product relies on the rigidity of the arbor and the setup of key tooling components.
- Rotary Knives
- Precision Spacers
- Stripper Rings & Rolls
*Proper setup minimizes edge wave and burr formation in recoiled strips.
Longitudinal Cutting
Shearing metal lengthwise with rotary knives under controlled tension.
Recoil Tension
Maintaining tight, uniform coils for downstream stamping or roll forming.
Arbor Rigidity
Minimizing deflection for burr-free edges. The foundation of accuracy lies in shaft stability.

Precision in Every Cut
In high-speed slitting, tolerance stacking is the enemy of quality. Any deviation across a set of spacers can result in cumulative error, leading to significant burr generation and knife chipping. Our tooling is ground to rigorous industrial standards to ensure your setup time is reduced and your edge quality is consistent from the first cut to the last.
Defect Analysis & Tooling Causes
| Defect Type | Visual Symptom | Likely Tooling Cause |
|---|---|---|
| Excessive Burr | Rough edge pointing up/down | Incorrect horizontal clearance setting or dull knife edges. |
| Camber (Snake) | Strip curving left or right | Uneven stripper ring pressure or misaligned arbor shafts. |
| Knife Marks | Scoring on strip surface | Stripper rings are wrong diameter (too small) or damaged. |
| Edge Wave | Rippled edges on strip | Excessive overlap setting causing metal deformation. |
