Kamar yadda muka sani, sawa kayan aikin carbide da aka yi da siminti yana da mahimmanci, wanda zai haifar da wahala a cikin niƙa mai nauyi kuma yana shafar ingancin mashin ɗin daidaitattun sassa.Saboda daban-daban workpiece kayan da yankan kayan, al'ada lalacewa da tsagewar tungsten carbide kayan aikin yana da wadannan yanayi uku:
1.Flank
Rigar wuka na baya yana faruwa ne kawai akan fuskar gemu.Bayan sawa, sai ya samar da fuskar da ta zama αo ≤0o, kuma tsayinsa VB yana nuna yawan lalacewa, wanda gabaɗaya yana faruwa ne lokacin da ake yanke karafa ko karafa na robobi a ƙananan saurin yankewa da ƙananan kauri (αc <0.1mm).A wannan lokacin, juzu'i na inji akan fuskar rake kaɗan ne, kuma zafin jiki ya yi ƙasa kaɗan, don haka lalacewa a fuskar rake yana da girma.
2.Crating lalacewa
Rake face wear yana nufin wurin lalacewa da ke faruwa musamman akan fuskar rake.Gabaɗaya, a mafi girman saurin yanke da kauri mai girma (αc> 0.5mm) lokacin yankan karafa na robobi, guntu suna fitowa daga fuskar rake, kuma saboda tashe-tashen hankula, zafin jiki da matsanancin matsin lamba, wani ramin jinjirin wata yana ƙasa akan fuskar rake kusa. yankan bakin.Adadin sawa akan fuskar rake an bayyana shi cikin yanayin zurfin rami KT.A lokacin da ake yin daidaitattun sassa, raƙuman jinjirin wata yana ƙara zurfafawa da faɗaɗawa a hankali, kuma yana faɗaɗawa zuwa ga yanke, har ma yana kaiwa ga guntuwa.
3.Ana sawa rake da fuska a lokaci guda
Rake da fuska ana sawa a lokaci guda yana nufin lalacewa a lokaci guda na rake da fuska akan kayan aikin carbide bayan yanke.Wannan wani nau'i ne na lalacewa wanda ya fi dacewa lokacin yankan karafa na filastik a matsakaicin yankan sauri da ciyarwa.
Jimlar lokacin yankan kayan aikin carbide tungsten tun daga farkon niƙa zuwa sarrafa madaidaicin sassa har sai adadin lalacewa ya kai iyakar lalacewa ana kiransa rayuwar kayan aikin carbide, wato, jimlar lokacin yankan tsafta tsakanin biyun regriding na kayan aikin carbide, wanda aka nuna ta "T".Idan iyakokin lalacewa iri ɗaya ne, tsawon rayuwar kayan aikin carbide, raguwar lalacewa na kayan aikin carbide.
