Malunga neDry Cutting

1. Yintoni iteknoloji yokusika okomileyo
Ngokwandiswa kolwazi lwendalo esingqongileyo kunye neemfuneko ezingqongqo zemithetho kunye nemimiselo yokhuseleko lwendalo esingqongileyo, iziphumo ezibi zoKugawula ulwelo kwimo engqongileyo ziya zicaca ngakumbi.Ngokwezibalo, kwiminyaka engama-20 kamva, iindleko zokusika ulwelo ziya kuba ngaphantsi kwe-3 I-% yexabiso le-workpiece.Okwangoku, kumashishini okuvelisa imveliso ephezulu, iindleko zokusika ukunikezelwa kwamanzi, ukugcinwa kunye nokuphinda kusetyenziswe kwakhona kunye kuya kuba ne-13% -17% yeendleko zokuvelisa i-workpiece, ngelixa iindleko zezixhobo zokusika kuphela i-2% -5% ,.Malunga ne-22% yexabiso elipheleleyo elinxulumene ne-Cutting fluid yindleko yokusika unyango lwe-fluid.I-Dry cutting luhlobo lwendlela yokwenza i-machining esetyenziselwa ukukhusela indalo kunye nokunciphisa iindleko ngaphandle kokusebenzisa Ukusika ulwelo ngokuqaphela kwaye ngaphandle kokupholisa.
Ukusika okomileyo akukona nje ukuyeka ukusebenzisa i-Cutting fluid, kodwa ukuqinisekisa ukusebenza kakuhle, umgangatho ophezulu wemveliso, ukuqina kwesixhobo esiphezulu kunye nokuthembeka kwenkqubo yokusika ngelixa uyeka ukusebenzisa i-Cutting fluid, efuna ukusetyenziswa kwezixhobo zokusika kunye nokusebenza kakuhle.Izixhobo zomatshini kunye amaziko ancedisayo athatha indawo yendima yokuSika ulwelo ekusikeni kwemveli ukufezekisa ukusika okomileyo okwenyani.2.Iimpawu zeteknoloji yokusika okomileyo
① Iitshiphusi zicocekile, azinangcoliseko, kwaye kulula ukuzisebenzisa kwakhona kwaye zilahlwe.② Izixhobo zokusika ukuhanjiswa kwamanzi, ukubuyiswa, ukuhluzwa kunye neendleko ezihambelanayo zigciniwe, inkqubo yemveliso yenziwe lula kwaye ixabiso lokutsalwa liyancipha.③ isixhobo sokwahlula phakathi kokusika ulwelo kunye neetshiphusi kunye nesixhobo sombane esihambelanayo asifakwanga.Isixhobo somatshini sixinene ngokwesakhiwo kwaye sithatha indawo encinci.④ Ayizukubangela ungcoliseko lwendalo esingqongileyo.⑤ Ayizi kubangela iingozi zokhuseleko kunye neengozi ezisemgangathweni ezinxulumene nokuSika ulwelo.
3. Malunga nezixhobo zokusika
① Isixhobo siya kuba nokumelana nobushushu obuphezulu kwaye sinokusebenza ngaphandle kokuSika ulwelo.Iialloyi ezintsha eziqinileyo, iiseramikhi zepolycrystalline, kunye nemathiriyeli yeCBN zezona zixhobo zikhethwayo zezixhobo zokusika ezomileyo. ngesixhobo esilungileyo sokususa itshiphu ekunciphiseni ukuqokelelwa kobushushu.③ Izixhobo zokusika ezomileyo kufuneka nazo zibe namandla aphezulu kunye nokuqina kwempembelelo kunezixhobo zokusika ezimanzi.
4. Izixhobo zesixhobo
Izinto zokugqumaUkwaleka kusebenza njengomqobo we-thermal kuba inomgangatho ophantsi kakhulu we-thermal conductivity kune-substrate yesixhobo kunye nezinto zokusebenza.Ke ngoko, ezi zixhobo zifunxa ubushushu obuncinci kwaye zinokumelana namaqondo aphezulu okusika.Ingaba kukuguqula okanye ukugaya, izixhobo ezigqunyiweyo zivumela iiparitha zokusika eziphezulu ngaphandle kokunciphisa ubomi besixhobo.Ii-Thinner coatings zinentsebenzo engcono phantsi kokutshintsha kweqondo lokushisa ngexesha lokusikwa kwempembelelo xa kuthelekiswa neengubo ezityebileyo.Oku kungenxa yokuba iingubo ezibhityileyo zinoxinzelelo oluphantsi kwaye azithandeki kakhulu ekuqhekekeni.Ukusika okomileyo kunokwandisa ubomi besixhobo ukuya kuthi ga kwi-40%, yiyo loo nto i-coatings ebonakalayo isetyenziswa ngokuqhelekileyo ukugqoka izixhobo zesetyhula kunye nokufakwa kokugaya.
I-cermetCermets inokumelana nobushushu obuphezulu bokusika kune-alloys eqhelekileyo, kodwa ayinakuxhathisa impembelelo ye-alloys eqinile, ukuqina ngexesha eliphakathi ukuya kumatshini onzima, kunye namandla ngexesha lesantya esisezantsi kunye namazinga aphezulu okutya.Nangona kunjalo, inobushushu obuphezulu kunye nokumelana nokunxiba phantsi kwesantya esiphezulu sokusika okomileyo, ixesha elide, kunye nokugqiba okungcono komphezulu wesixhobo sokusetyenzwa.Xa isetyenziselwa ukusetyenzwa kwemathiriyeli ethambileyo kunye ne-viscous, ikwanako ukumelana nokwakhiwa kwetshiphu kunye nomgangatho olungileyo womphezulu.Iicermets zinobuntununtunu ngakumbi kuxinzelelo olubangelwa kukwaphuka kunye nokutya xa kuthelekiswa neealloyi eziqinileyo ezingagqunywanga ezineengubo ezingcono.Ke ngoko, isetyenziswa ngcono kwizixhobo zokusebenza ezichanekileyo kunye neemeko eziqhubekayo zokusika ezinomgangatho ophezulu womphezulu.
iiseramikhi
Ukuzinza, okukwazi ukucutshungulwa kwisantya esiphezulu sokusika kunye nokuhlala ixesha elide.I-alumina ecocekileyo inokumelana nokushisa okuphezulu kakhulu, kodwa amandla ayo kunye nokuqina kwayo kuphantsi kakhulu.Ukuba iimeko zokusebenza azilungile, kulula ukuqhawula.Ukongeza umxube we-alumina okanye i-titanium nitride kunokunciphisa uvakalelo lwe-ceramics ukuphuka, ukuphucula ukuqina kwabo, kunye nokuphucula ukuxhathisa kwabo.
I-CBN toolsCBN sisixhobo esinzima kakhulu, esifanelekileyo kwizinto zomatshini ezinobunzima obuphezulu kune-HRC48.Inobulukhuni obuphezulu bobushushu obuphezulu-ukuya kuthi ga kwi-2000 ℃, nangona inamandla empembelelo ephezulu kunye nokumelana nokuqhekeka kunemela yeCeramic.

I-CBN ine-conductivity ephantsi ye-thermal kunye namandla aphezulu oxinzelelo, kwaye inokumelana nokushisa okusika okuveliswa ngesantya esiphezulu sokusika kunye ne-rake angle engalunganga.Ngenxa yokushisa okuphezulu kwindawo yokusika, i-workpiece material iyancipha, inceda ukwenza ii-chips.
Kwimeko yokuguquka okomileyo, izixhobo zokusebenza ze-CBN ziqhele ukusetyenziselwa ukutshintsha iinkqubo zokusila ngenxa yokukwazi ukufezekisa ukuchaneka okuphezulu kunye nokugqitywa kwendawo.Izixhobo ze-CBN kunye nezixhobo ze-ceramic zifanelekile ukujika ukuqina kunye nokugaya ngesantya esiphezulu.
OPT umgangatho ophezuluCBN ufake
Izixhobo zePCD
Umzekelo,Faka iPCD,PCD milling cutter,PCD reamer.
  

Idayimani yePolycrystalline, njengesona sixhobo sinzima sokusika isixhobo, ayigugi.Ukuwelda izilayi ze-PCD kwiincakuba ze-alloy eziqinileyo kunokonyusa amandla azo kunye nokumelana nefuthe, kwaye ubomi babo besixhobo buphindwe ka-100 kobulukhuni bealloyi.
Nangona kunjalo, ukunxulumana kwe-PCD yentsimbi kwi-Ferrous kwenza olu hlobo lwesixhobo lukwazi ukucubungula izinto ezingezizo i-ferrous.Ukongeza, i-PCD ayinakumelana nokushisa okuphezulu kwindawo yokusika edlula i-600 ℃, ngoko ke, ayikwazi ukusika izinto ezinobunzima obuphezulu kunye ne-ductility.
Izixhobo ze-PCD zifaneleke ngokukodwa ukusetyenzwa kweentsimbi ezingenayo i-ferrous, ingakumbi i-silicon ephezulu ye-aluminium alloys ene-friction enamandla.Ukusebenzisa imiphetho ebukhali yokusika kunye nee-engile ezinkulu zehariki ukusika ngokufanelekileyo ezi zixhobo, ukunciphisa uxinzelelo lokusika kunye ne-chip buildup.
