Indlela yokukhetha isiXhobo seDayimane, isixhobo sePCD kunye nesixhobo seCBN seeMveliso zoMachining
PCD izixhobo eziluncedo:
Isixhobo se-PCD sineenzuzo zobomi besixhobo eside kunye nesantya esiphezulu sokususa isinyithi, kodwa sinobugwenxa bexabiso eliphezulu kunye neendleko eziphezulu zokulungisa. Namhlanje, ukusebenza kwezixhobo ze-aluminium akufani nangaphambili. Xa kusetyenzwa izinto ezahlukeneyo ezisanda kuphuhliswa aluminiyam ialloy, ukuze kuphunyezwe ukulungelelaniswa kwemveliso kunye nomgangatho wokusetyenzwa, uphawu lwesixhobo sePCD kunye neeparamitha zejometri kufuneka zikhethwe ngononophelo ukuze zihambelane neemfuno ezahlukeneyo zokusetyenzwa. Olunye utshintsho lwezixhobo ze-PCD kukunciphisa okuqhubekayo kweendleko zokucwangcisa. Ngaphantsi kwempembelelo edibeneyo yoxinzelelo lokhuphiswano lweemarike kunye nokuphuculwa kwenkqubo yokuvelisa izixhobo, ixabiso lezixhobo ze-PCD liye lahla ngaphezu kwe-50%. Ezi ndlela zikhokelela ekunyuseni ukusetyenziswa kwezixhobo ze-PCD kwi-aluminium processing material, kwaye ukusetyenziswa kwezixhobo ze-PCD kuthintelwe ngezinto ezahlukeneyo.
Iinzuzo zesixhobo se-CBN:
Inokunciphisa kakhulu inani leenguqu zesixhobo kunye nokugqoka izixhobo, ukuhlawulela ixesha elichithwe ekulungiseni umatshini, wenze ukusebenza kakuhle kwesixhobo somatshini we-CNC udlale ngokupheleleyo, ukwenzela ukuba ufezekise ukujika emva kokucima isixhobo somatshini we-CNC (ukutshintsha indawo ukugaya ngokujika), kwaye ingasetyenziselwa ukugaya ngokuphindaphindiweyo.
