Ukuthelekiswa kweNtsimbi ye-Speed-Speed ​​kunye ne-Cemented Carbide Materials

Isinyithi esinesantya esiphezulu (HSS) kunye ne-cemented carbide zizinto ezimbini ezisetyenziswa ngokuqhelekileyo kumashishini ahlukeneyo, ngokukodwa kwizixhobo zokusika kunye nezicelo zomatshini. Zombini izixhobo zibonisa iimpawu ezizodwa ezenza ukuba zilungele iinjongo ezithile. Kule nqaku, siya kuthelekisa kwaye sithelekise iimpawu zentsimbi ephezulu kunye ne-cemented carbide, egxininise ekubunjweni kwabo, ubunzima, ubunzima, ukuxhatshazwa kokugqoka kunye nokusebenza ngokubanzi.

Ukuqulunqwa:

I-Speed-Speed ​​Steel: Isinyithi esinesantya esiphezulu yi-alloy eyakhiwe ngokuyinhloko ngentsimbi, i-carbon, i-cobalt, i-tungsten, i-molybdenum, kunye ne-vanadium. Ezi zinto ze-alloying zongeza ubulukhuni bemathiriyeli, ukuxhathisa ukunxiba, kunye namandla aphezulu obushushu.

I-Cemented Carbide: I-carbide ene-cemented, eyaziwa ngokuba yi-tungsten carbide, iqukethe isigaba se-carbide enzima (ngokuqhelekileyo i-tungsten carbide) efakwe kwi-binder metal efana ne-cobalt okanye i-nickel. Olu luhlu lubonelela ngezinto ezinobunzima obukhethekileyo kunye nokumelana nokugqoka.

Ukuqina:

I-Speed-Speed ​​Steel: I-HSS idla ngokuba nobunzima obususela kwi-55 ukuya kwi-70 HRC (isikali se-Rockwell C). Eli nqanaba lobunzima livumela izixhobo ze-HSS ukuba zinqumle ngokufanelekileyo uluhlu olubanzi lwezinto, kuquka intsimbi, intsimbi, kunye nentsimbi.

I-Cemented Carbide: I-carbide ene-cemented idume ngobulukhuni bayo obugqithisileyo, ihlala ifikelela kwi-80 ukuya kwi-95 HRA (i-Rockwell A isikali). Ukuqina okuphezulu kwenza izixhobo ze-carbide zesamente zilungele ukwenza izinto eziqinileyo ezifana ne-titanium alloys, iintsimbi eziqiniweyo, kunye ne-composites.

Ukuqina:

I-Speed-Speed ​​Steel: I-HSS ibonisa ukuqina okulungileyo kwaye inokumelana nempembelelo ephezulu kunye nemithwalo yothuso, iyenze ilungele ukusika okuphazamisekileyo kunye nokusebenza komatshini onzima. Ukuqina kwayo kukwaququzelela ukugaywa ngokutsha kunye nokubunjwa ngokutsha kwezixhobo.

I-Cemented Carbide: Nangona i-carbide ene-cemented inzima kakhulu, i-brittle xa ithelekiswa ne-HSS. Inokuthi itshiphu okanye iqhekeke phantsi kweempembelelo ezinzima okanye imithwalo eyothusayo. Nangona kunjalo, amabakala e-carbide anamhlanje abandakanya ukuqina okuphuculweyo kwaye anokumelana neempembelelo eziphakathi ukuya kokukhanya.

Nxiba ukuxhathisa:

I-Speed-Speed ​​Steel: I-HSS inokumelana nokunxiba kakuhle, ngakumbi xa isetyenziswa kwizantya zokusika ezisezantsi. Nangona kunjalo, ngesantya esiphezulu sokusika okanye xa umatshini wokwenza izinto ezinobunzima obuphezulu, ukuxhathisa kwe-HSS kunokungonelanga.

I-Cemented Carbide: I-carbide ene-cemented idume ngokuxhathisa okungaqhelekanga kokunxiba nakwimeko ezinzima zomatshini. Isigaba esinzima se-carbide sinikezela ukuchasana okuphezulu kwi-abrasive wear, ukuvumela izixhobo ze-carbide ukugcina umda wazo wokusika ixesha elide.

Ukusebenza:

I-Speed-Speed ​​Steel: Izixhobo ze-HSS zigqwesa kuluhlu olubanzi lwezicelo zokusika ngenxa yokuguquguquka kwazo, ukuqina, kunye nokulula kokulula. Ziyafaneleka kwimisebenzi ye-machining yenjongo jikelele kwaye ineendleko ezisebenzayo xa kuthelekiswa ne-carbide enesamente.

I-Cemented Carbide: Izixhobo ze-carbide ze-cemented zisetyenziselwa ukuchaneka okuphezulu kunye nokusebenza kakuhle komatshini. Baqhuba kakuhle kakhulu ekufuneni izicelo ezinesantya esiphezulu sokusika, ubomi besixhobo esongezelelweyo, kunye nokwanda kwemveliso. Nangona kunjalo, zibiza kakhulu kunezixhobo zeHSS.

Isiphelo:

I-Speed-speed steel and cemented carbide zimbini izinto ezixabisekileyo kwishishini lesixhobo sokusika, ngalinye linamandla kunye nemida yalo. Isinyithi esinesantya esiphezulu sibonelela ngokuqina okuhle, ukuguquguquka, kunye nokusebenza kakuhle kweendleko, okwenza kube lula kuluhlu olubanzi lwezicelo zomatshini. Ngakolunye uhlangothi, i-carbide ene-cemented igqwesa kubunzima, ukumelana nokunxiba, kunye nokuzinza kweqondo lokushisa eliphezulu, okwenza kube yinto ekhethiweyo yokukhetha iintsimbi ezilukhuni kunye nezinye izinto ezinzima.

Ukuqonda iimfuno ezithile zomsebenzi womatshini kunye nezinto zokusebenza kubalulekile ekukhetheni izinto ezifanelekileyo. Izinto ezifana nesantya sokusika, ubulukhuni bezinto eziphathekayo, nobomi besixhobo obufunwayo zimele ziqwalaselwe ngenyameko. Ekugqibeleni, ukhetho phakathi kwentsimbi ephezulu kunye ne-cemented carbide iya kuxhomekeka kwisicelo esithile kunye neziphumo ezifunwayo.
