Kwinkqubo yokuvelisa kunye nemveliso yanamhlanje, kudla ngokuba nzima ukucubungula kunye nokuvelisa ngezixhobo eziqhelekileyo eziqhelekileyo, ezifuna izixhobo ezingezona eziqhelekileyo ezenziwe ngokwezifiso ukugqiba umsebenzi wokusika.Izixhobo zensimbi ze-Tungsten ezingezona eziqhelekileyo, oko kukuthi, izixhobo ze-carbide ze-cemented ezingekho-standard-shaped special-shaped-shaped, zidla ngokusetyenziswa ngokweemfuno zemizobo kunye nokusika ukusebenza ngokweemfuno ezithile zabathengi bomatshini.
Ukuveliswa kwezixhobo ezisemgangathweni ngokuyintloko kukusika ubuninzi bezinto eziqhelekileyo zetsimbi okanye iindawo ezingezizo.Xa i-workpiece iphathwe ubushushu kunye nokwanda kobunzima okanye ezinye iimfuno ezikhethekileyo ze-workpiece azikwazi ukunamathela kwisixhobo, isixhobo esisemgangathweni asinakukwazi ukuhlangabezana nale nto Ngokubhekiselele kwiimfuno zokusika, kuyimfuneko ukwenza imveliso ekujoliswe kuyo kwizinto ezithile. ukukhethwa kwezinto eziphathekayo, i-angle edge edge kunye nesixhobo sokwakheka kwezixhobo zensimbi ze-tungsten ngokweemfuno ezikhethekileyo zamacandelo acutshungulwayo.
Iintsimbi ze-tungsten ezenziwe ngokwezifiso zentsimbi ezingaqhelekanga zihlulwe zibe ziindidi ezimbini: ezo ezingadingi ukwenza ngokwezifiso ezizodwa kunye nezo zifuna ukulungiswa okukhethekileyo.Akukho mfuneko yezixhobo ezikhethekileyo ze-tungsten zentsimbi ezingaqhelekanga zokusombulula iingxaki ezimbini: iingxaki zobungakanani kunye neengxaki zoburhabaxa bomphezulu.
Kwingxaki yobungakanani, kufuneka kuqatshelwe ukuba ubungakanani bobungakanani akufanele bube bukhulu kakhulu, kwaye ingxaki yobunzima bomhlaba inokufezekiswa ngokuguqula i-angle yejometri yecala lokusika.
Izixhobo ezikhethekileyo ze-tungsten zentsimbi ezingeyomgangatho zisombulula ezi ngxaki zilandelayo:
1. I-workpiece ineemfuno ezizodwa zemilo.Kwizixhobo ezinjalo ezingezizo eziqhelekileyo, ukuba iimfuno azikho nzima kakhulu, kulula kakhulu ukuhlangabezana neemfuno.Nangona kunjalo, kufuneka kuqatshelwe ukuba ukuveliswa kwezixhobo ezingezizo ezisemgangathweni kunzima ukuvelisa kunye nokusebenza.Ngoko ke, umsebenzisi ungcono ukuba angahlangabezani neemeko zokuvelisa kunye nokucubungula.Ifuna iimfuno ezichanekileyo eziphezulu kakhulu, iimfuno ezichanekileyo zibonakalisa iindleko kunye nomngcipheko omkhulu.
2. Umsebenzi unamandla akhethekileyo kunye nobunzima.Ukuba i-workpiece iye yafumana unyango olushushu, ubunzima kunye namandla ezixhobo eziqhelekileyo azikwazi ukuhlangabezana nenkqubo yokusika, okanye ukunamathela kweso sixhobo kunzulu, okudinga iimfuno ezongezelelweyo kwizinto ezithile zesixhobo esingaqhelekanga.Izixhobo eziphezulu ze-carbide, ezizezi zixhobo eziphezulu ze-tungsten zensimbi, zikhetho lokuqala.
3. Amalungu omatshini aneemfuno ezikhethekileyo zokususwa kwetshiphu kunye neemfuneko zokubamba i-chip.Olu hlobo lwesixhobo luyimpahla ekulula ukuyiqhuba
Kuyilo kunye nokuveliswa kwezixhobo zentsimbi ze-tungsten ezingaqhelekanga, kukho iingxaki ezininzi ezifuna ukuhoywa:
1. I-geometry yesixhobo inzima kakhulu, kwaye isixhobo sixhomekeke kwi-deformation ngexesha lenkqubo yokunyanga ukushisa, okanye uxinzelelo lwengingqi lugxininisekile, olufuna ingqalelo kwiimfuno zokutshintsha kwengcinezelo yendawo apho uxinzelelo lugxininiswe khona.
2. Izitshetshe zensimbi ze-Tungsten zizinto ezinqabileyo, ngoko kufuneka uhlawule ingqalelo enkulu ekukhuselweni kwe-blade shape ngexesha lokucubungula okuthe ngqo.Emva kokuba iimeko ezingaqhelekanga zenzeka, ziya kubangela umonakalo ongeyomfuneko kwiimela.
