Overview: What is CNC Milling?
Milling is a fundamental CNC machining process where cutting tools remove material from a solid blank to create a finished or semi-finished part, precisely matching your CAD design. In CNC milling, the workpiece is securely clamped in a vise or fixture on the worktable. Depending on the machine, the table can rotate and tilt, enabling 3D movement via X-axis and Y-axis linear motions. The rotating spindle holds the cutting tool, which removes material to form complex geometries and features. Multi-axis milling excels as both the spindle and worktable move independently along multiple axes, allowing intricate part machining with exceptional precision and repeatability.
