Vacuum mafuta kudzima ndiko kupisa workpiece muvacuum kudziyisa mukamuri uye kuifambisa kune quenching mafuta tangi.Iyo yekudzima svikiro imafuta.Mafuta ekudzima mutangi yemafuta anokurudzirwa nechisimba kuti atonhodze workpiece nokukurumidza.
Iyi modhi ine zvakanakira iyo inopenya workpiece inogona kuwanikwa kuburikidza nekudzima mafuta ekutsvaira, ine yakanaka microstructure uye kuita, hapana oxidation uye decarburization pamusoro.Kutonhora kwekudzima kwemafuta kunokurumidza kupfuura kudzima gasi.
Vacuum oiri inonyanya kushandiswa kudzima muvacuum oiri yepakati yealloy structural simbi, inotakura simbi, chitubu simbi, die simbi, yakakwirira-kumhanya simbi nezvimwe zvinhu.
