CNC 4-axis machining centre designed for working on the profile faces at any angle, as the electrically-driven spindle is provided with rotary movement perpendicular to the CNC longitudinal (X) axis from +90° to -90° with respect to the vertical direction. This CNC movement, besides positioning the electrically-driven spindle at any angular setting in the work range, also allows rapid passing from one face to the other, thus optimising the cycle and machining time. Another advantage of this machining centre is that two or more workpieces of different sizes can be machined at the same time.
