The machine is suitable for the processing of complex large aluminum alloy parts, and is suitable for themulti-angle processing of large die-cast aluminum alloy parts and structural parts such as battery trays, door frames, instrument panel supports of new energy vehicles. With AIC two-axis milling head to complete five-axis machining, simple structure, no wear, no back backlash, high precision. Therefore, the processing time of thewhole machine is greatly shortened and the efficiency is improved.
