How to choose the blade for Oscillating knife cutting machine
How to choose the blade for an Oscillating knife-cutting machine? What is the difference between a circular knife and a vibration knife? What materials are they suitable for?

When selecting knife blades for a CNC oscillating knife-cutting machine, it’s essential to understand the different types of blades, their working principles, characteristics, and suitable materials. Here’s a comparison between circular blades and oscillating blades to help you make an informed decision.
Circular Blades
Working Principle: Circular blades are cut by rotating the blade, similar to a circular saw used in woodworking. The robotic arm moves the blade across the work surface, adjusting angles to achieve any shape.
Characteristics:
- Produces a smooth, even cut with no burrs, frayed edges, or patterns.
- Does not create the charred edges associated with laser cutting.
- The round shape may lead to varying cutting depths due to curvature, especially noticeable when cutting thicker materials, resulting in overcutting.

Suitable Materials:
- Single-layer materials, such as paper, film, or mesh fabrics.
Oscillating Blades
Working Principle: Oscillating blades cut by utilizing vertical vibrations of the blade. The robotic arm moves and adjusts the blade’s angle on the work surface to achieve various shapes.
Characteristics:
- Fast cutting speed with excellent cutting quality.
- Particularly effective for cutting multilayer materials, and handling thicker materials with ease.

Suitable Materials:
- Multilayer materials, foam, rubber, EVA, textiles, and more.
Summary and Selection Advice
When choosing a blade, consider the type and thickness of the materials you will be cutting:
- For single-layer or thin materials: Opt for circular blades to ensure smooth cutting edges.
- For multilayer or thicker materials: Choose oscillating blades to enhance cutting efficiency and quality.
While both types of blades have similar configurations and specifications and can be customized, they differ significantly in cutting performance and material suitability. Selecting the right blade based on your specific needs will help improve cutting efficiency and product quality.
