Our slitting blades are crafted with wear-resistant materials and undergo forging, heat treatment, and grinding processes. They offer superior accuracy, wear-resistance, oil-resistance, heat-resistance, and acid/alkali resistance. Ideal for thin and soft-surfaced materials, they maintain precision over extended use without deformation.
We provide OEM and custom services based on technical drawings or samples. Our slitting blades boast exceptional processing accuracy:
- Surface roughness: ≤ 0.002mm
- Flatness and parallelism: ≤ 0.001mm
- Diameter size: 300-1000mm
- Thickness: 0.5-300mm
- Blades heat treatment hardness: tailored to blade material and cutting material thickness
- Heat treatment method: vacuum deoxidation and salt bath furnace treatment
Materials available for circular blades and knives include SKH-9, SKD-11, LD, W6Mo5Cr4V2AL, H13K, M42, K30, ASP60 power alloy steel, and custom options.
