Ø60mm Tungsten Carbide Circular Slitting Blade 0.5mm Ultra-Thin with 17° V-Edge for Precision Film and Foil Cutting

In precision slitting and micro-cutting applications, tool thickness and blade geometry determine the quality of the cut and the yield of the final product. This Ø60mm tungsten carbide circular slitting blade is engineered to meet the most demanding precision cutting requirements. With an ultra-thin 0.5mm thickness and a highly specialized 17° V-shaped cutting edge (with a 1.66mm cutting depth), it delivers exceptionally clean cuts with minimal kerf loss and burr formation.

• Ultra-Thin 0.5mm Profile: Minimizes kerf loss and material waste, making it ideal for high-value materials such as battery electrodes and thin films.
• 17° V-Edge Geometry: The precisely ground V-shaped cutting edge (DET - A) concentrates cutting force for clean shearing and separation with minimal deformation of the workpiece.
• Tight Tolerances: The outer diameter (Ø60), inner bore (Ø19 +0.02/0), and thickness (0.5 +0.05/0) are machined to exacting tolerances to ensure precise fit on slitting machine arbors.
• Mirror Surface Finish: Ra 0.2–0.4μm surface finish on the blade faces and cutting edge reduces friction, prevents material adhesion, and ensures smooth chip evacuation.
• Precision Lapped Flatness: 0.01mm flatness and parallelism prevent blade wobble, ensuring consistent cutting quality and extended blade life.

This ultra-thin circular slitting blade is manufactured through a rigorous, multi-stage process to ensure the highest precision:

• Step 1: Powder Preparation — High-purity tungsten carbide powder is precisely blended with 6% cobalt binder.
• Step 2: Isostatic Pressing — The blended powder is pressed using isostatic pressing technology, ensuring uniform density throughout the thin disc blank.
• Step 3: Vacuum Sintering — Blanks are vacuum-sintered at precisely controlled temperatures to achieve full density and optimal mechanical properties.
• Step 4: Precision Lapping & Grinding — The blade faces are precision lapped to achieve 0.01mm flatness and parallelism, and the OD/ID are precision-ground to the specified tolerances.
• Step 5: V-Edge Grinding — The 17° V-shaped cutting edge (with a 1.66mm edge distance) is precision-ground using specialized profile grinding equipment to achieve a razor-sharp, burr-free cutting edge.
• Step 6: Mirror Polishing — The blade faces and cutting edge are polished to Ra 0.2–0.4μm, reducing friction and preventing material adhesion.
• Step 7: Quality Inspection — 100% dimensional inspection including CMM verification of OD, ID, thickness, flatness, parallelism, and edge geometry. Edge quality inspected under high-magnification optical equipment.
