Main Features
Optimized for Core Cutting: The HSS rotary knife for core slitting is specifically treated to cleanly shear thick paper cores without deformation or fraying of the paper.
Large ID Customization: Expert in achieving high precision on the large inner diameter bore, critical for concentricity and safe, high-speed rotation.
Superior Edge Retention: Use of HSS and specialized heat treatment ensures these are long lasting paper tube cutting knives.
Precision Grinding: The entire annular surface and the cutting bevel are precision ground annular shear finished to achieve a mirror-like smoothness, reducing friction and dust.
Reduced Jamming: The ring shape and precise bevel angle are designed for effective material clearance, preventing jamming in continuous production.
Advantages
Clean, Accurate Cuts: Delivers a smooth, burr-free edge on paper cores, essential for the quality of the wound material (film, foil, paper).
High-Speed Performance: Material and balance are optimized for the high rotational speeds found in high speed film core cutter machinery.
Cost-Effective Durability: The durability of our blades means lower consumption and reduced operational costs over time.
Custom Fitment Guarantee: We guarantee that our custom large hole rotary blades will fit perfectly and interchange with your existing OEM equipment.
