Izindlela zokukhiqiza ze-carbide indexable CNC inserts

1. I-powder metallurgy

Iningi le-carbide okufakiwe kwe-CNC okunenkomba akhiqizwa yi-powder metallurgy. Izinyathelo eziyinhloko zale nqubo zihlanganisa ukukhethwa kwezinto zokusetshenziswa, ukulungiswa kwezimpushana, ukuxuba, ukucindezela, nokucwilisa. Izinto zokusetshenziswa ngokuvamile zakhiwa ingxube ye-tungsten carbide, i-cobalt, i-tantalum, i-niobium nezinye izimpushana. Lawa ma-powder axutshwa ngesilinganiso esithile futhi acindezelwe ukuze enze okungenalutho kokufakiwe. I-blank ibe i-sintered ekushiseni okuphezulu ukuze kwakheke amakristalu e-block ngaphansi kwezinga lokushisa elithile kanye nokucindezela, futhi ekugcineni abe i-carbide inserts.

2. Ukucindezela kwe-isostatic okushisayo

Ngaphezu kwenqubo ye-powder metallurgy, enye indlela yokukhiqiza evame ukusetshenziswa ukucindezela kwe-isostatic okushisayo. Le ndlela iyinqubo lapho ingxube yempushana yezinto ezingavuthiwe ingaphansi kwengcindezi ethile ekushiseni okuphezulu ukuze yakhe ukuma kokuqala kwethuluzi. Uma kuqhathaniswa ne-powder metallurgy, ukucindezela kwe-isostatic okushisayo kungathola okusanhlamvu okuningi okufanayo kanye nokucolile, ngakho le ndlela isetshenziswa kabanzi ekukhiqizeni okufakwayo kwe-carbide okufunwa kakhulu.

3. Ukucubungula okulandelayo

Ngemuva kokukhiqizwa kwe-carbide blade, uchungechunge lokucubungula okulandelayo luyadingeka ukuze kuqinisekiswe ukunemba nokusebenza kwe-blade. Ngokuvamile kuhlanganisa ukugaya, ukupholishwa, ukucutshungulwa konqenqema, ukudlula, ukunamathela, njll. Izinyathelo ezithile zenqubo yokukhiqiza zizohluka ngokuya ngezinto ezingavuthiwe namathuluzi. 

Ukufakwa kwe-carbide kasimende okukhiqiziwe kunezakhiwo ezinhle kakhulu njengokuqina okuphezulu, ukumelana nokugqoka okuphezulu, nokumelana nokugqwala. Zisetshenziswa kabanzi ku-aerospace, ukukhiqiza izimoto, ezokwelashwa, nezinye izinkambu zokucubungula insimbi.
