Kwi-machining ye-CNC, kukho abasiki abahlukeneyo bokugaya, njengeEnd Mill, Roughing End Mill, Ukugqiba Ukuphela Kwe Mill, Ball End Mill, njalo njalo.Ulwalathiso olujikelezayo lwe-milling cutter luhlala rhoqo, kodwa ulwalathiso lwesondlo luyaguquguquka.Kukho izinto ezimbini eziqhelekileyo zokusila: ukungqusha phambili kunye nokusila ngasemva.
Umgca wokusika we-milling cutter uxhomekeke kwimithwalo yempembelelo rhoqo xa unqumla. Ukuze ufezekise impumelelo yokugaya, kuyimfuneko ukuqwalasela ukudibanisa okuchanekileyo phakathi komgca wokusika kunye nezinto eziphathekayo ngexesha lokusika kunye nexesha lokusika.Kwinkqubo yokugaya, i-workpiece yondliwa ngendlela efanayo okanye echaseneyo ukuya kwicala lokujikeleza kwe-milling cutter, echaphazela ukusika ngaphakathi nangaphandle kwenkqubo yokugaya, kunye nokuba kusetyenziswe iindlela zokugaya phambili okanye ngasemva.
1. Umthetho weGolide wokugaya-ukusuka kwi-Thick to Thin
Xa ukugaya, kubalulekile ukuqwalasela ukubunjwa kwee-chips.Umba ogqibayo wokwenziwa kwetshiphu yindawo yomsiki wokusila, kwaye kubalulekile ukuzabalazela ukwenza iitshiphusi ezishinyeneyo xa iblade isika kwaye iitshiphusi ezibhityileyo xa iblade isika ukuze kuqinisekiswe inkqubo yokusila ezinzileyo.
Khumbula umgaqo wegolide wokugaya, "ukusuka kwingqimba ukuya kwincinci," ukuqinisekisa ukuba ubukhulu beetshiphu xa umgca wokusika unqunyulwa uncinci kangangoko kunokwenzeka.
2. Ukugaya phambili
Kwi-milling yangaphambili, isixhobo sokusika sondliwa kwicala lokujikeleza.Logama nje isixhobo somatshini, isixhobo, kunye nesixhobo sokusebenza sivumela, ukugaya phambili kuhlala kuyindlela ekhethwayo.
Kwi-edge milling, ubukhulu be-chip buya kuncipha ngokuthe ngcembe ukusuka ekuqaleni kokusika ukuya kwi-zero ekupheleni kokusika.Oku kunokuthintela umgca wokusika ukukrazula kunye nokuxubha umphezulu wenxalenye ngaphambi kokuthatha inxaxheba ekusikeni.
Ubukhulu be-chip enkulu bunenzuzo, njengoko amandla okusika adla ngokutsala i-workpiece kwi-milling cutter, egcina i-cutting edge cutter.Nangona kunjalo, ngenxa yokukhululeka kwe-cutter yokugaya itsalwa kwi-workpiece, isixhobo somatshini kufuneka siphathe i-gap feed ye-workbench ngokususa umva.Ukuba umsiki wokusila utsalwa kwindawo yokusebenza, ukutya kuya kwanda ngokungalindelekanga, okunokukhokelela kubukhulu obugqithisileyo betshiphu kunye nokuqhekeka komphetho.Kwezi meko, cinga ukusebenzisa i-reverse milling.
3. Ukuguqula umva
Kwi-reverse milling, isalathiso sokutya kwesixhobo sokusika sichasene nolwalathiso lwaso lokujikeleza.
Ubukhulu be-chip bukhula ngokuthe ngcembe ukusuka kwi-zero kude kube sekupheleni kokusika.Umgca wokusika kufuneka uphoqeleke ukuba unqumle, ukwenzela ukuba uvelise ukukrwela okanye ukupholisa umphumo ngenxa yokuxhatshazwa, ukushisa okuphezulu kunye nokudibanisa rhoqo kunye nomsebenzi onzima obangelwa ngumda wokusika wangaphambili.Konke oku kuya kunciphisa ubomi besixhobo.
Iichips ezityebileyo kunye nobushushu obuphezulu obuveliswe ngexesha lokusikwa komphetho wokusika kuya kukhokelela kuxinzelelo oluphezulu, oluya kunciphisa ubomi besixhobo kwaye ngokuqhelekileyo kubangele umonakalo okhawulezayo kumda wokusika.Isenokubangela ukuba iitshiphusi zinamathele okanye zidibanise kumda wokusika, oya kuthi emva koko uzithwale kwindawo yokuqala yokusikwa okulandelayo, okanye ubangele ukuba umphetho wokusika uqhekeke kwangoko.
Amandla okusika athande ukutyhala umsiki wokusila kude nomsebenzi, ngelixa amandla eradial ethanda ukuphakamisa i-workpiece kwi-workbench.
Xa kukho utshintsho olubalulekileyo kwisibonelelo somatshini, ukubuyisela umva kusenokuba luncedo ngakumbi.Xa usebenzisa ukufakwa kwe-ceramic ukucubungula i-superalloys, kuyacetyiswa ukuba kusetyenziswe i-reverse milling, kuba ii-ceramics zivakalelwa kwimpembelelo eyenziwa xa usika kwi-workpiece.
4. Isixhobo sokusebenza
Isalathiso somxhesho wesixhobo sokusika sineemfuno ezahlukeneyo kwisixhobo sokusebenza.Ngexesha lenkqubo yokugaya umva, kufuneka ikwazi ukuxhathisa amandla okuphakamisa.Ngexesha lenkqubo yokugaya, kufuneka ikwazi ukumelana noxinzelelo oluphantsi.
Izixhobo zokusika ze-OPT ngumthengisi okumgangatho ophezulu weCarbide milling cutters.
Siyakuxhasa ekufumaneni iimfuno zakho zonyaka ngamaxabiso akhuphisanayo, sinikezela ngomgangatho ophezulu kunye noluhlu olubanzi lweenkonzo.
