A vibration knife CNC cutting machine is a precision tool that uses high-frequency vertical vibration of the knife blade (typically 20,000–50,000 vibrations per minute) combined with CNC (Computer Numerical Control) programming to cut materials. Unlike laser cutters (which use heat) or rotating blades (which rely on torque), its vibration enables clean, non-damaging cuts on flexible, thick, or layered materials. How It Works (Core Principles) 1. CNC Programming: The user imports a design file (e
