ball milling features and working

CNC Milling: What is it, How It Works, Operations, Overview

Milling is usually used as a finishing or secondary process for a workpiece that has already been machined where it is used to add special features like holes, slots, or threads. The general use of milling is the basic concept of the CNC process where material is gradually removed from the workpiece to create the desired shape or form.
