5 Axis Machining

5-axis CNC machining involves simultaneous movement along five axes—three linear (X, Y, Z) and two rotational. This capability allows for the creation of complex parts in a single setup, significantly enhancing precision and efficiency. By moving the cutting tool and workpiece along these five different axes, the 5-axis CNC can produce highly intricate shapes and detailed features.
