Ukujika kuyindlela yokusika i-workpiece kwi-lathe usebenzisa ukujikeleza kwendawo yokusebenza ngokumalunga nesixhobo.Ukujika yeyona ndlela isisiseko kunye neqhelekileyo yokusika.Uninzi lwezixhobo zokusebenza ezinomgangatho ojikelezayo zinokucutshungulwa ngeendlela eziguqukayo, ezinje ngomgangatho wangaphakathi nangaphandle we-cylindrical, umphezulu wangaphakathi nangaphandle we-conical, ubuso bokuphela, i-grooves, intambo, kunye neendawo ezijikelezayo.Iileyile eziqhelekileyo zinokwahlulwa zibe ziileyile ezithe tyaba, iileyile zomgangatho, iileyile ezithe nkqo, iileyile ze-turret kunye neeprofiling lathes, uninzi lwazo ziintambo ezithe tye.
Ngenxa yophuhliso lwesayensi kunye nobuchwepheshe bale mihla, izinto ezahlukeneyo zobunjineli ezinokuqina okuphezulu kunye nobunzima obuphezulu zisetyenziswa ngakumbi nangakumbi.Itekhnoloji yokuguqula isiko inzima okanye ayinakwenzeka ukucubungula ezinye izinto ezinobunzima obuphezulu kunye nobunzima obuphezulu.Itekhnoloji yokuguqula kanzima yenza oku kwenzeke kwaye ivelise iinzuzo ezicacileyo kwimveliso.
1. Intshayelelo kwiimpawu zokujika
(1) Ukujika okuphezulu ukusebenza kakuhle
Ukujika kunokusebenza okuphezulu kunokugaya.Ukujika kudla ngokuthatha ubunzulu obukhulu bokusika kunye nesantya esiphezulu sesixhobo sokusebenza, kwaye izinga lokususa isinyithi lihlala liphindaphindwe kaninzi elo lokusila.Ukuguqula, iindawo ezininzi zinomatshini kwi-clamping enye, ngelixa ukugaya kufuna ukufakela okuninzi, okukhokelela kumaxesha amafutshane ancedisayo kunye nokuchaneka okuphezulu kwesikhundla phakathi kweendawo ezinomatshini.
(2) Iindleko zokufaka izixhobo ziphantsi.Xa imveliso ifana, utyalo-mali lwe-lathe ngokucacileyo lungcono kunelo lokugaya, kwaye iindleko zenkqubo yokuncedisa nazo ziphantsi.Ukuvelisa i-batch encinci, ukujika akudingi izixhobo ezikhethekileyo, ngelixa i-batch processing enkulu yeendawo ezichanekileyo zifuna izixhobo zomatshini we-CNC ezinobunzima obuhle, ukuchaneka kokubeka okuphezulu kunye nokuphindaphinda ukuchaneka kokubeka.
(3) Ifanelekile kwiimfuno zemveliso zebhetshi ezincinci eziguquguqukayo.I-lathe ngokwayo yindlela yokucubungula eguquguqukayo kunye noluhlu olubanzi lokucubungula.I-lathe kulula ukuyisebenzisa kwaye ukujika kunye nokubamba ngokukhawuleza.Xa kuthelekiswa nokusila, ukujika okunzima kunokuhlangabezana ngcono neemfuno zemveliso eguquguqukayo.
(4) Ukujika nzima kunokwenza ukuba amalungu afumane ukuchaneka komatshini
Ubuninzi bobushushu obuveliswa ekujikeni okunzima kuthathwa yioli yokusika, kwaye akuyi kubakho ukutshiswa kwendawo kunye nokuqhekeka njengokugaya.ukuchaneka kwesikhundla.
2. Ukuguqula izixhobo zesixhobo kunye nokukhethwa kwazo
(1) Izixhobo zokusika i-carbide edibeneyo
Izixhobo zokusika i-carbide ezifakwe kwi-coated zidityaniswe nenye okanye ngaphezulu kweengqimba zokwaleka kunye nokumelana nokunxiba kakuhle kwizixhobo eziqinileyo zokusika i-carbide.Ukugquma ngokuqhelekileyo kudlala iindima ezimbini ezilandelayo: I-conductivity ye-thermal ephantsi kakhulu ye-matrix kunye ne-workpiece material iyanciphisa umphumo we-thermal we-matrix yesixhobo;ngakolunye uhlangothi, inokuphucula ngokufanelekileyo i-friction kunye nokubambelela kwindlela yokusika kunye nokunciphisa isizukulwana sokusika ukushisa.Xa kuthelekiswa nezixhobo zokusika i-carbide ene-cemented, izixhobo zokusika i-carbide ezifakwe kwi-coated ziye zaphuculwa kakhulu ngokubhekiselele kumandla, ubunzima kunye nokuxhatshazwa kokugqoka.
(2) Isixhobo se-Ceramic
Izixhobo zokusika i-Ceramic zineempawu zobunzima obuphezulu, amandla aphezulu, ukunganyangeki kakuhle, ukuzinza kweekhemikhali okulungileyo, ukusebenza kakuhle kwe-anti-bonding, i-coefficient ephantsi ye-friction kunye nexabiso eliphantsi.Ekusetyenzisweni okuqhelekileyo, ukuqina kuphezulu kakhulu, kwaye isantya sinokuphindaphinda kaninzi kunokwe-carbide enesamente.Ilungele ngokukodwa ukulungiswa kwezinto ezinobunzima obuphezulu, ukugqiba kunye nokulungiswa kwesantya esiphezulu.
(3) Isixhobo seCubic boron nitride
Ukuqina kunye nokumelana nokunxiba kwe-cubic boron nitride yesibini kuphela kwidayimane, kwaye inobulukhuni obuphezulu beqondo lobushushu.Xa kuthelekiswa nezixhobo ze-ceramic, ukuxhathisa ubushushu kunye nokuzinza kweekhemikhali kubi kakhulu, kodwa amandla empembelelo kunye nokumelana nokutyumza kungcono.Ukuba awufuni ukusebenza ezantsi, ufuna ukulahla imeko, kwaye ufuna ukufunda inkqubo ye-UG, unokongeza iqela le-QQ 192963572 ukuze ufunde iteknoloji yeprogram ye-CNC.Isetyenziswe ngokubanzi ekusikeni kwentsimbi eqinile, i-pearlitic grey cast iron, i-chilled cast iron kunye ne-superalloy, njl.
3. Ukukhethwa kweoli yokusika
(1) Ukumelana nokushisa kwezixhobo zensimbi zensimbi kubi, kwaye ukuqina kulahleka kumaqondo aphezulu, ngoko ke ukusika ioli kunye nokusebenza kakuhle kokupholisa, i-viscosity ephantsi kunye ne-fluidity efanelekileyo iyafuneka.
(2) Xa isixhobo sensimbi esinesantya esiphezulu sisetyenziselwa ukusika isantya esiphezulu, isixa sokusika sikhulu kwaye kuveliswa ubushushu obukhulu.Ukusika ioli kunye nokupholisa okulungileyo kufuneka kusetyenziswe.Ukuba izixhobo zetsimbi ezikhawulezayo zisetyenziselwa ukugqiba okuphakathi kunye nesantya esisezantsi, ioli yokusika i-viscosity ephantsi ngokuqhelekileyo isetyenziselwa ukunciphisa i-frictional adhesion phakathi kwesixhobo kunye ne-workpiece, inqanda ukubunjwa kweengqungquthela zokusika, kunye nokuphucula ukuchaneka kwe-machining.
(3) Izixhobo ze-carbide ezine-cemented zinendawo ephezulu yokunyibilika kunye nobunzima, iikhemikhali ezingcono kunye nokuzinza kwe-thermal, kunye nokusika okungcono kakhulu kunye nokumelana nokugqoka kunezixhobo zetsimbi ezikhawulezayo.Ioli yokusika isulfure esebenzayo ingasetyenziswa ngokubanzi.Ukuba ukusika okunzima, ubushushu bokusika buphezulu kakhulu, kwaye isixhobo silula ukugqoka ngokukhawuleza.Ngeli xesha, ioli yokusika i-vulcanized engasebenziyo kufuneka isetyenziswe kwaye izinga lokuhamba kweoli yokusika kufuneka linyuswe ukuze kuqinisekiswe ukupholisa okwaneleyo kunye ne-lubrication.
(4) Izixhobo ze-Ceramic, izixhobo zedayimane kunye nezixhobo ze-cubic boron nitride zonke zinobunzima obuphezulu kunye nokumelana nokunxiba, kwaye ngokubanzi zisebenzisa i-oyile yokusika i-vulcanized ephantsi ye-viscosity ngexesha lokusika ukuze kuqinisekiswe ukugqitywa kwendawo yokusebenza.
Ezi zingentla ziyimpawu kunye nezilumkiso zenkqubo yokuguqula.Ukukhethwa okufanelekileyo kwezixhobo kunye nokusika imveliso yeoli kunokuphucula kakhulu umgangatho womsebenzi.
