Njengoko sonke siyazi, ukunxitywa kwezixhobo ze-carbide ze-cemented kunzulu, okuya kubangela ubunzima bokugaya obunzima kunye nokuchaphazela umgangatho womatshini weendawo ezichanekileyo.Ngenxa yezixhobo ezahlukeneyo zokusebenza kunye nezinto zokusika, ukunxiba okuqhelekileyo kunye nokukrazula kwezixhobo ze-tungsten carbide zinezi meko zintathu zilandelayo:
1.Ukunxiba kweFlank
Ukunxitywa kweemela ngasemva kwenzeka kuphela kwiflanki yobuso.Emva kokugqoka, yenza i-facet eyenza i-αo ≤0o, kunye nokuphakama kwayo kwe-VB kubonisa ubuninzi bokugqoka, okwenzeka ngokubanzi xa kunqunyulwa isinyithi esine-brittle okanye isinyithi seplastiki kwisantya esisezantsi sokusika kunye nobukhulu obuncinci bokusika (αc <0.1mm).Ngeli xesha, ukungqubuzana komatshini kwi-rake face kuncinci, kwaye iqondo lokushisa liphantsi, ngoko ukunxiba kwi-rake face kukhulu.
2.Cukunxiba kwamaxabiso
Ukunxitywa kobuso beRake kubhekisa kwindawo yokunxiba eyenzeka ikakhulu kubuso beharika.Ngokubanzi, kwisantya esiphezulu sokusika kunye nobukhulu obukhulu bokusika (αc> 0.5mm) xa usikwa iintsimbi zeplastiki, iitshiphusi ziphuma ebusweni beharika, kwaye ngenxa yokukhuhlana, ubushushu obuphezulu kunye noxinzelelo oluphezulu, icrater igatywa kubuso beraki kufutshane. umgca wokusika.Ubungakanani bokunxitywa kobuso behariki bubonakaliswe ngokobunzulu becrater KT.Ngexesha lokucocwa kweendawo ezichanekileyo, icrater yecrescent iyancipha kancinci kancinci kwaye iyanda, kwaye iyanda kwicala lecala lokusika, ide ikhokelele ekutshiphukeni.
3.Irakhi kunye nobuso beflanki bunxitywa ngaxeshanye
Irakhi kunye nobuso beflank bunxitywa ngaxeshanye ibhekisa ekunxityweni ngaxeshanye kweharika kunye nobuso beflank kwizixhobo ze-carbide emva kokusikwa.Olu luhlobo lokugqoka oluqhelekileyo xa usika isinyithi seplastiki kwisantya esiphakathi kunye nokutya.
Ixesha elipheleleyo lokusika isixhobo se-tungsten carbide ukusuka ekuqaleni kokugaya ukuya ekusetyenzweni kweendawo ezichanekileyo de isixa sokunxiba sifikelele kumda wokunxiba sibizwa ngokuba bubomi besixhobo se-carbide, oko kukuthi, isixa sexesha lokusika elicocekileyo phakathi kokuphinda kabini ukugaya. isixhobo se-carbide, esiboniswa ngu "T".Ukuba imida yokunxiba iyafana, ixesha elide ubomi besixhobo se-carbide, ukucotha ukunxiba kwesixhobo se-carbide.
