What is CNC Machining?

2 Milling employs rotating multi-point cutting tools to shape the workpiece. Milling tools are either horizontally or vertically oriented and include end mills, helical mills, and chamfer mills. The CNC milling process also utilizes CNC-enabled milling machinery, referred to as mill machines or mills, which can be horizontally or vertically
