What are the differences between CNC machining and wire EDM? What is the approximate time difference and price difference between using wire EDM and CNC to machine inner cavities?

A: CNC can machine inner cavities larger than R4 (inclusive) and smaller than 80mm (inclusive). CNC can machine arc corners or sharp corners smaller than R4.

CNC is approximately 50%-70% faster, depending on the brick sample and quantity. CNC is more expensive, and the price is calculated based on the brick sample and quantity.
