  • Introduction to CNC machining | Hubs

    Face milling cutters are used to remove materials from large flat surfaces. They have a larger diameter than end mill tools, so they require fewer passes to machine large areas, reducing the total machining time and producing flat surfaces. A face milling step is often employed early in the machining cycle to prepare the dimensions of the block.
