Uthini umahluko phakathi kwezixhobo zeCNC kunye neencakuba?
Izixhobo ze-CNC zisetyenziselwa ukusebenza okuphezulu kunye nokuchaneka okuphezulu kwezixhobo zomatshini we-CNC. Ukuze kuphunyezwe ukusebenza kakuhle okuzinzileyo nokulungileyo, izixhobo ze-CNC zineemfuno eziphezulu kunezixhobo eziqhelekileyo ngokoyilo, ukwenziwa kunye nokusetyenziswa. Umahluko omkhulu phakathi kwezixhobo ze-CNC kunye neeblades kule miba ilandelayo.
(1) Umgangatho wokuvelisa ochanekileyo
Ukuze ulungelelanise ngokuzinzileyo umphezulu weendawo ezichanekileyo, iimfuno ezingqongqo kunezixhobo eziqhelekileyo zibekwe phambili ukwenzela ukuveliswa kwezixhobo (kubandakanywa nezixhobo zesixhobo) ngokuchaneka, ukuchaneka komphezulu, kunye nokunyamezela kwejometri, ngokukodwa izixhobo ze-indexable. Ukuphindaphindwa kobungakanani bencam yokufaka (umphetho wokusika) emva kokufakwa kwesalathisi, ubungakanani kunye nokuchaneka kweendawo eziphambili ezifana ne-cutter body groove kunye neendawo zokubeka, kunye noburhabaxa bomhlaba kufuneka buqinisekiswe ngokungqongqo. Kwaye umlinganiselo we-dimensional, ukuchaneka komatshini wesiseko kufuneka kuqinisekiswe.
(2) Ukuphuculwa kwesakhiwo sesixhobo
Isakhiwo sesixhobo esiphezulu sinokuphucula kakhulu ukusebenza kakuhle kokusika. Ngokomzekelo, izixhobo zokugaya i-CNC ezinesantya esiphezulu ziye zamkela imiphetho enemilo yamaza kunye nezakhiwo ezinkulu ze-helix kwisakhiwo. Isakhiwo esinokutshintshwa kunye nesilungelelanisiweyo, njengesakhiwo sokupholisa sangaphakathi, asikwazi ukusetyenziswa ngamathuluzi aqhelekileyo omatshini.
(3) Ukusetyenziswa ngokubanzi kwemathiriyeli ekumgangatho ophezulu yezixhobo zokusika
Ukwandisa ubomi benkonzo yesixhobo kunye nokuphucula amandla esixhobo, i-alloy yensimbi ephezulu isetyenziselwa isixhobo somzimba wezixhobo ezininzi ze-CNC, kunye nonyango lobushushu (njenge-nitriding kunye nolunye unyango lomhlaba) lwenziwa. , ukwenzela ukuba ikwazi ukufaneleka kwisixa esikhulu sokusika, kwaye ubomi besixhobo bufutshane. inokuphuculwa kakhulu (iimela eziqhelekileyo zisebenzisa intsimbi yekhabhoni ecinyiweyo kunye nephakathi). Ngokuphathelele imathiriyeli yokusika, izixhobo ze-CNC zokusika zisebenzisa amabanga amatsha ahlukeneyo e-carbide enesamente (amasuntswana amahle okanye amasuntswana e-ultrafine) kunye nemathiriyeli enzima kakhulu.
(4) Ukukhethwa kwe-chip breaker efanelekileyo
Izixhobo ezisetyenziswa kwizixhobo zoomatshini be-CNC zineemfuno ezingqongqo kwi-chip breakers. Xa umatshini, isixhobo somatshini asikwazi ukusebenza ngokuqhelekileyo ukuba isixhobo asinqunyulwanga (ezinye izixhobo zomatshini we-CNC kunye nokusika zenziwa kwindawo evaliweyo), ngoko ke kungakhathaliseki ukuba i-CNC ijika, i-milling, i-drilling okanye i-boring machine, ii-blades zilungiselelwe ezahlukeneyo. izinto zokusebenza kunye neenkqubo. Ukusika okunengqiqo. Ijiyometri ye-chip yenza ukuba i-chip iqhekezekile ngexesha lokusika.
(5) Unyango lokwaleka kumphezulu wesixhobo (incakuba)
Ukuvela kunye nokuphuhliswa kwesixhobo (i-blade) iteknoloji yokugubungela umphezulu ikakhulu ngenxa yokuvela kunye nophuhliso lwezixhobo ze-CNC. Ekubeni i-coating inokuphucula kakhulu ubunzima besixhobo, ukunciphisa ukungqubuzana, ukuphucula ukusebenza kakuhle kunye nobomi benkonzo, ngaphezu kwe-80% yazo zonke iintlobo ze-carbide indexable ze-CNC izixhobo ziye zamkela iteknoloji yokugqoka. I-coated Carbide Inserts inokusetyenziselwa ukusika okomileyo, nto leyo edala iimeko ezilungele ukukhuseleka kwendalo kunye nokusikwa kohlaza.
