Automatic detection of aluminium ingot shape dimension cooperates with position control turnover aluminum ingots can be automatically reverse it. The whole line can be configured longitudinal, side milling cutter, milling 6, 8, suction + compaction system innovation can be separate milling clastic according to transport required size suction and compression processing, can achieve 99% high absorption rate, realize the aluminum surface roughness Ra 1 microns or less, output 6 pieces/h.
