What is CNC milling?
CNC milling uses rotational cutting tools to remove material from a workpiece to produce finished parts and products. This manufacturing process works well for many materials, including metals, polymers, wood and glass. CNC milling systems generally have 3 linear degrees of freedom: the X, Y and Z axis. This allows for top-notch precision and detailing. HLH also offers more advanced, 5-degree systems, where the tool head and machining bed (A and B axis) can also rotate. 5-axis CNC machines can produce parts with high geometric complexity without needing multiple machine setups.
