High-Speed Rotating Round Knife Cutting Tool with Replaceable Blade for Multi-Material CNC Cutting

The Round Knife Cutting Tool, also known as the Replaceable Vibrating Knife, is one of the most versatile and widely used tools for CNC digital cutting machines. Designed for high-speed, continuous cutting, it delivers exceptional accuracy and clean edges on a wide range of flexible and semi-rigid materials.

Whether used in leather goods manufacturing, footwear production, automotive interiors, packaging, composites, or textiles, the round knife provides superior performance where both speed and accuracy are required.

The round knife combines rotary motion + micro-vibration, allowing it to smoothly cut through materials without dragging, tearing, or distorting edges. This ensures clean and consistent lines even on soft, stretchable, or thick layers.

The tool accepts quick-change circular blades, minimizing downtime during production. Operators can replace the blade in seconds—no recalibration needed.

Engineered for industrial accuracy, the round knife cuts materials such as:

• Genuine leather & PU leather
• Microfiber
• Textiles & technical fabrics
• Foam, EVA, sponge
• Carbon fiber & fiber-reinforced composites
• Rubber and soft packaging materials
• Cardboard and corrugated materials

It is ideal for industries requiring fast, stable, smooth cutting performance.

Made of high-hardness, wear-resistant steel, the rotating blade provides long-lasting sharpness. The design reduces friction and heat, extending both blade and tool lifespan.

The round knife tool can be installed on:

• Oscillating knife cutting machines
• Digital flatbed CNC cutters
• Multi-function cutting systems
• Textile & leather cutting plotters

Support for custom sizes and tool holders is also available.

• Smooth Cutting on Soft or Stretchable Materials - Unlike a straight oscillating blade, the round knife rotates as it cuts, reducing drag and preventing material distortion.
• High Efficiency for Mass Production - Suitable for continuous cutting processes, making it ideal for factories producing large quantities of parts.
• Superior Edge Quality - Minimal fraying, cleaner curves, and more precise small-radius shapes.
• Safer and More Stable Operation - The circular shape allows even pressure distribution, reducing the risk of blade breakage.

We provide round knife tools in multiple sizes and configurations:

• Diameter options (e.g., 28mm, 45mm, 60mm, 80mm)
• High-speed vibration motors
• Standard or heavy-duty torque versions
• Compatible holders for various brand digital cutters
• Optional tool depth control

Custom manufacturing available upon request.

Integrating a Round Knife Cutting Tool into your digital cutter dramatically enhances productivity, accuracy, and cutting quality—especially for soft, flexible, or composite materials.
