Kwinkqubo yomatshini, kudla ngokuba nzima ukusebenzisa izixhobo ezisemgangathweni, ngoko ke ukuveliswa kwezixhobo ezingekho mgangathweni kubaluleke kakhulu kumatshini.
Ukusetyenziswa kwezixhobo ezingezizo eziqhelekileyo kwi-metal cutting kudla ngokubonakala kwi-milling, ngoko ke eli phepha lizisa ngokukodwa ukuveliswa kwezixhobo ezingaqhelekanga kwi-milling.
Ngenxa yokuba ukuveliswa kwezixhobo eziqhelekileyo kujoliswe ekusikeni iindawo eziqhelekileyo zetsimbi okanye iindawo ezingezizo zetsimbi ezinoluhlu olubanzi lwemigangatho, xa ukuqina kwe-workpiece kwanda ngenxa yonyango olugqithisiweyo, okanye i-workpiece yintsimbi engenasici, inzima kakhulu. kulula ukunamathela kwisixhobo, kwaye kukho ezinye iimeko apho ijometri yomphezulu we-workpiece inzima kakhulu, okanye umgangatho owenziwe ngomatshini uneemfuno eziphezulu zobunzima, izixhobo eziqhelekileyo azikwazi ukuhlangabezana neemfuno zokucubungula.Ke ngoko, kwinkqubo yokwenziwa komatshini, kuyimfuneko ukwenza uyilo olujoliswe kuyo kwizinto zesixhobo, imilo yejometri yomphetho, i-engile yejometri, njl., enokuthi yahlulwe ibe ngamacandelo amabini: ukwenza ngokwezifiso okukhethekileyo kunye nokungalungi. ngokwezifiso ezizodwa.
I. Izixhobo ezingezizo ezenzelwe ukusombulula ezi ngxaki zilandelayo: ubukhulu, uburhabaxa bomphezulu, ukusebenza kakuhle kunye neendleko
(1).Ingxaki yobungakanani.
Unokukhetha isixhobo esiqhelekileyo esinobungakanani obufana nobukhulu obufunekayo, obunokusonjululwa ngokutshintsha ukucola, kodwa kufuneka kuqatshelwe amanqaku amabini:
1. Umahluko wesayizi akufanele ube mkhulu kakhulu, ngokuqhelekileyo ungabi ngaphezu kwe-2mm, kuba ukuba umehluko wesayizi mkhulu kakhulu, kuya kubangela ukuba i-groove shape yesixhobo itshintshe, kwaye ichaphazele ngokuthe ngqo indawo ye-chip kunye ne-angle yejometri;
2. Ukuba isiphelo sokugaya i-cutter kunye nomngxuma we-edge sinokusila kwisixhobo esiqhelekileyo somatshini, iindleko ziphantsi.Ukuba i-keyway milling cutter ngaphandle komngxuma edge ayinakugaywa kwisixhobo somatshini esiqhelekileyo, kufuneka igalelwe kwisixhobo esikhethekileyo somatshini wokudibanisa i-axis emihlanu, kwaye iindleko ziya kuba phezulu.
(2).Uburhabaxa bomphezulu.
Oku kunokufezekiswa ngokuguqula i-angle yejometri yomda.Ngokomzekelo, ukwandisa iqondo leengile zangaphambili kunye nasemva kuya kuphucula kakhulu uburhabaxa bomphezulu we-workpiece.Nangona kunjalo, ukuba isixhobo somatshini somsebenzisi asiqinanga ngokwaneleyo, kunokwenzeka ukuba umphetho onqabileyo unokuphucula uburhabaxa bomphezulu endaweni yoko.Lo mba unzima kakhulu, kwaye isiphelo sinokuthathwa kuphela emva kokuhlalutya kwendawo yokucubungula.
(3).Ukusebenza kakuhle kunye nemiba yeendleko
Ngokubanzi, izixhobo ezingezizo ezisemgangathweni zinokudibanisa iinkqubo ezininzi zibe sisixhobo esinye, esinokugcina ixesha lokutshintsha isixhobo kunye nexesha lokuqhuba, kwaye siphucule kakhulu ukusebenza kakuhle kwemveliso!Ngokukodwa kumacandelo kunye neemveliso ezicutshungulwe kwiibhetshi, iindleko ezigciniweyo zikhulu kakhulu kuneendleko zesixhobo ngokwaso;
II Izixhobo ezifuna ukulungiswa ngokukodwa zixazulule iingxaki ezintathu: imilo ekhethekileyo, amandla akhethekileyo kunye nobunzima, kunye ne-chip ekhethekileyo kunye neemfuno zokususa i-chip.
(1).Umsebenzi oza kucutshungulwa uneemfuno zemilo ekhethekileyo.
Umzekelo, yandisa isixhobo esifunekayo ukuze machining, yongeza isiphelo izinyo reverse R, okanye iimfuno ze-angle taper ekhethekileyo, ukubamba iimfuno isakhiwo, edge ubude ubude bomda wolawulo, njl. kuselula ukusombulula.Eyona nto imele iqatshelwe kukuba ukulungiswa kwezixhobo ezingekho mgangathweni kunzima.Ke ngoko, umsebenzisi akufuneki alandele ngokugqithisileyo ukuchaneka okuphezulu ukuba unokuhlangabezana neemfuno zokusetyenzwa.Ngenxa yokuba ukuchaneka okuphezulu ngokwako kuthetha iindleko eziphezulu kunye nomngcipheko ophezulu, oya kubangela inkunkuma engafunekiyo kumthamo wemveliso kunye neendleko zeumvelisi.
(2).Umsebenzi owenziweyo unamandla akhethekileyo kunye nobunzima.
Ukuba i-workpiece ishushu, amandla kunye nobunzima buphezulu, kwaye izixhobo eziqhelekileyo azikwazi ukunqunyulwa, okanye ukunamathela kwesixhobo kunzima, okudinga iimfuno ezikhethekileyo zesixhobo.Isisombululo esiqhelekileyo kukukhetha izixhobo zesixhobo eziphezulu, ezifana ne-cobalt-equkethe izixhobo zetsimbi ezikhawulezayo ezinobunzima obuphezulu bokusika izinto ezicinyiweyo kunye ne- tempered workpiece, kunye nezixhobo eziphezulu ze-carbide ze-cemented zingasetyenziselwa ukucubungula izinto ezinobunzima obuphezulu, kwanokusila kusenokusetyenziswa endaweni yokusila.Kakade ke, kukwakho nezinye iimeko ezikhethekileyo.Ngokomzekelo, xa kusenziwa iinxalenye ze-aluminium, kukho uhlobo lwesixhobo esibizwa ngokuba yi-superhard tool kwimarike, engafanelekanga.Nangona iinxalenye ze-aluminiyam zithambile kwaye kunokuthiwa kulula ukusetyenzwa, izinto ezisetyenziselwa isixhobo esinamandla ngokwenene yintsimbi ye-aluminiyam enesantya esiphezulu.Le nto inzima ngokwenene kunentsimbi eqhelekileyo enesantya esiphezulu, kodwa iya kubangela ubudlelwane phakathi kwezinto ze-aluminium xa kusetyenzwa iinxalenye ze-aluminium, Yenza isixhobo sinxibe ngakumbi.Ngeli xesha, ukuba ufuna ukufumana ukusebenza kakuhle okuphezulu, ungakhetha intsimbi ye-cobalt enesantya esiphezulu endaweni yoko.
3. Umsebenzi oza kucutshungulwa uneemfuno ezikhethekileyo zokubamba itshiphu kunye nokususwa kwetshiphu.
Ngeli xesha, inani elincinci lamazinyo kunye ne-chip ejulile yokubamba i-groove kufuneka ikhethwe, kodwa olu yilo lunokusetyenziswa kuphela kwizinto ezilula ukuzisebenzisa, ezifana ne-aluminium alloy.Kukho iingxaki ezininzi ekufuneka ziqwalaselwe kwinkqubo
uyilo kunye nokucutshungulwa kwezixhobo ezingekho mgangathweni: ubume bejometri yesixhobo sinzima, kwaye isixhobo sixhomekeke ekugobeni, ukuguqulwa, okanye ukuxinzelela uxinzelelo lwendawo ngexesha lonyango lobushushu.Ke ngoko, ingqwalasela kufuneka ihlawulwe ukunqanda iindawo ezithanda ukugxininiswa kuxinzelelo ngexesha loyilo, kwaye kumalungu anotshintsho olukhulu lobubanzi, inguqu ye-bevel okanye uyilo lwenyathelo kufuneka longezwe.Ukuba isiqwenga esincinci esinobude obukhulu kunye nobubanzi, kufuneka sihlolwe kwaye silungiswe rhoqo xa sicinywa kwaye sigxininiswe kwinkqubo yonyango lokufudumala ukulawula ukuguqulwa kwayo kunye nokuphuma kwayo.Izinto eziphathekayo zesixhobo zi-brittle, ngokukodwa i-alloy eqinile, eyenza isixhobo siphuke xa sidibana nokunyakaza okukhulu okanye ukuqhutyelwa kwetorque kwinkqubo.Oku ngokuqhelekileyo akubangeli umonakalo omkhulu kwinkqubo yokusebenzisa izixhobo eziqhelekileyo, kuba isixhobo sinokutshintshwa xa siphukile, kodwa kwinkqubo yokusebenzisa izixhobo ezingezizo eziqhelekileyo, ukutshintshwa kwezinto ezinokwenzeka kuncinci, ngoko ke xa isixhobo siqhekeza, Uluhlu lweengxaki, ezifana nokulibaziseka kokunikezelwa, kuya kubangela ilahleko enkulu kumsebenzisi.
Zonke ezi ngasentla zijolise kwisixhobo ngokwaso.Enyanisweni, ukuveliswa kwezixhobo ezingekho semgangathweni akukho lula.Le yiprojekthi ecwangcisiweyo.Amava esebe loyilo lomvelisi kunye nokuqonda iimeko zokucutshungulwa komsebenzisi kuya kuchaphazela ukuyila kunye nokuveliswa kwezixhobo ezingezizo eziqhelekileyo.Ukucubungula kunye neendlela zokufumanisa isebe lokuvelisa umvelisi liya kuchaphazela ukuchaneka kunye ne-geometric angle yezixhobo ezingaqhelekanga.Ukutyelela ngokuphindaphindiweyo, ukuqokelelwa kwedatha kunye nolwazi lwesebe lokuthengisa lomvelisi kuya kuchaphazela kwakhona ukuphuculwa kwezixhobo ezingezizo eziqhelekileyo, eziza kudlala indima ebalulekileyo kwimpumelelo yomsebenzisi ekusebenziseni izixhobo ezingezizo eziqhelekileyo.Isixhobo esingaqhelekanga sisixhobo esikhethekileyo esiveliswe ngokweemfuno ezizodwa.Ukukhetha umenzi onamava atyebileyo kuya konga ixesha elininzi kunye namandla kumsebenzisi.
