Grooved knife bushes
High-speed, clean cutting of foil, cable, paper, plastic, labels, and packaging – with exceptional durability. Consult our team for the optimal fit for your machines.
Cutting bushes / Grooved knife bushes / Slitter systems
Grooved knife bushes are indispensable components frequently used across diverse industries for precision cutting of aluminum foil, cable, paper, plastic, labels, non-woven fabrics, and advanced packaging materials. When integrated into modern slitter systems, this specialized cutting configuration offers distinct operational advantages, ensuring clean separation and minimal downtime in high-speed converting and processing lines.
High-Performance
materials and metallurgy
We fabricate premium grooved knife bushes using a comprehensive selection of engineered materials tailored to your exact operational demands. Our standard stock materials include high-grade tool steels such as 1.2067 and 1.2379, chosen for their exceptional wear resistance and structural integrity.
However, raw material selection is only part of the equation. Optimal cutting performance relies heavily on precise material properties and meticulous heat treatment processes. By tightly controlling hardening and tempering parameters, our grooved knife sockets achieve the ideal balance of hardness and toughness, making them fully suitable for extreme cutting speeds and continuous multi-shift operations without premature edge degradation.
Uncompromising manufacturing tolerances
Achieving flawless cuts in web handling and slitting requires absolute micro-precision. Our advanced in house manufacturing capabilities allow us to achieve exceptional thickness tolerances down to +/- 0.001 mm. Furthermore, we guarantee parallelism accuracies within the narrowest possible tolerances, ensuring even pressure distribution and consistent engagement across the entire cutting edge.
Depending on your specific slitter system and cutting process, we deliver the finest surface qualities, including polished, lapped, and burnished finishes. These ultra-smooth surface textures minimize friction, prevent material buildup or adhesion, and act as the foundational prerequisite for maximizing both tool service life and final cut quality.
The Herbertz quality commitment
At Herbertz GmbH and Co. KG, we process exclusively superior steel grades for all our grooved knife sockets and slitter components. Every metal batch is deliberately selected based on the specific mechanical stresses, thermal loads, and material characteristics of your targeted application.
Application engineering and custom solutions
Selecting the right combination of bushing geometry, steel grade, and surface finish is critical to optimizing your production efficiency. Our experienced technical team is always glad to support you in analyzing your operational parameters and determining the exact knife and bushing configuration for your specific slitter system.
