60° Crush Cutting Knives are precision-manufactured slitting knives designed for rewinders, flexographic printing machines, inspection equipment, and slitting machines. The 60-degree cutting edge provides controlled crush-cutting performance for a wide range of paper, film, composite, and nonwoven web materials.
Manufactured from K100 and 100Cr6 high-quality steels, these knives are suitable for cutting lightweight paperboard, adhesive tapes, labels, metal films, flexible laminates, composite materials, and nonwoven fabrics (NWF).
Standard knife diameters range from 35 mm to 180 mm, with custom dimensions available according to customer drawings, machine specifications, and application requirements.

Although 60° is the primary cutting angle of this knife series, 30° and 45° cutting angles can also be manufactured for applications requiring different cutting geometries.

These 60° Crush Cutting Knives are designed for use with pneumatic knife holders used in slitting, printing, inspection, and converting systems.
WINGCHONG KNIFE can also manufacture custom counter sleeves, bottom knife shaft components, and related slitting accessories according to customer drawings to ensure accurate installation and system compatibility.

60° Crush Cutting Knives are commonly used in:
● Slitter rewinders
● Flexographic printing machines
● Inspection machines
● Slitting machines
● Label converting
● Flexible packaging
● Adhesive tape converting
● Film and foil processing
● Nonwoven converting
Custom Manufacturer: Manufactured according to drawings, samples, or machine specifications.
High-Quality Knife Materials: K100 and 100Cr6 steels are available for different cutting requirements.
Precision Edge Geometry: 60° cutting edges provide controlled crush-cutting performance.
Flexible Edge Profiles: Rounded and serrated edge configurations are available.
Complete Component Support: Counter sleeves and bottom shaft components can be manufactured to match your slitting system.
B2B Manufacturing Capability: Suitable for OEM replacement, machine builders, distributors, and industrial users.
Abrasive Cutting Knives are industrial cutting tools specifically designed for cutting abrasive rolls such as sandpaper and abrasive cloth.
Dished knives are circular cutting tools used for shear-type slitting. Unlike completely flat “flat knives,” their blades feature a concave geometric shape (resembling a plate or dish), a design that enables them to generate specific lateral cutting forces during rotational shearing.
Adhesive materials: Self-adhesive labels, adhesive tape, various composite films (die-cutting can create a temporary seal along the cut edges).
Elastic/soft materials: Rubber, non-woven fabric (NWF), textiles, tissue paper.
Abrasive/hard materials: Materials such as sandpaper that can quickly wear down standard sharp blades.
