Njengoko sonke sazi, ukunxitywa kwezixhobo ze-carbide ze-carbide kubaluleke kakhulu, nto leyo eya kubangela ubunzima kwisisele esinzima kwaye sichaphazele umgangatho womatshini wenxalenye yokuchaneka. Ngenxa yezixhobo ezahlukeneyo zomsebenzi kunye nezixhobo zokusika, izixhobo zokunxiba kunye nokukrazula izixhobo ze-tungsten ezinezi meko zintathu zilandelayo:
1.Flank inxibile
Ukunxiba ngasemva kwenzeke kuphela kubuso obuneflethi. Emva kokunxiba, yenza i-tyto ≤0o ≤0o, kwaye ukuphakama kwayo i-VB ibonisa inani lokunxiba, okona kusenzeka ngokukhawuleza xa kunqunyulwa isantya esincinci se-Brict kunye ne-αc encinci (αc <0.1). Ngeli xesha, ukungqinelana koomatshini kubuso obutshiweyo, kwaye iqondo lobushushu liphantsi, ke ukunxiba ebusweni obutshintsho kuphakamile.
2.CUkunxiba rater
I-rake ubuso ibhekisa kwiNdawo eNtethweni eyenzekayo ikakhulu kubuso obuhlungu. Ngokubanzi, kwisantya esiphezulu sokusika kunye nobubanzi obukhulu bokusika (i-αc> 0.5mm) xa usike izinyithi zeplasitiki, kwaye ngenxa yokuxinana, ubushushu obuphezulu kunye noxinzelelo oluphezulu, i-crescent ye-crescent bubuso obujikelezileyo. Isixa sokunxibisela ubuso be-rake sivezwe ngokwemigangatho ye-crater kt. Ngexesha lomatshini wenxalenye yokuchaneka, iCrescent Crater ngokuthe ngcembe iyakhula kwaye iyanda, kwaye yandise kwicala lomphetho osikelweyo, nokuba likhokelele ekuchitheni.
3.I-rake kunye ne-flank yobuso banxibe ngexesha elinye
I-rake kunye ne-flank yobuso inxibile ngexesha elinye Ibhekisa kwi-rake ngaxeshanye ye-rake kunye neflathi yobuso kwi-carbide yezixhobo emva kokusika. Olu luhlobo lokunxiba oluxhaphakileyo xa usike izinyithi zeplasitiki kwizintya kunye nezondla.
Ixesha lokusika lilonke lesixhobo se-tungsside ukusuka ekuqaleni kokucima iinxalenye zezixhobo zokunxiba zibizwa ngokuba sisixhobo sokunxiba esine-carbide, oko kukuthi, kuboniswa ". Ukuba imida yokunxiba iyafana, ixesha elide ubomi besixhobo se-carbide, ukunciphisa isixhobo sesixhobo se-carbide.
