What are the differences between CNC machining and wire EDM? What is the approximate time difference and price difference between CNC machining of internal cavities using wire EDM and CNC?

A: CNC can machine internal cavities with a radius of R4 (inclusive) and above, and a diameter of 80mm (inclusive) and below. CNC can also machine rounded corners or sharp corners with a radius of R4 or below.

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.
