Isisiki sokusila sisetyenziselwa ntoni? Ukunxiba i-milling cutter ngexesha lokusetyenziswa

Ngexesha lenkqubo yokugaya, i-milling cutter ngokwayo iya kunxitywa kwaye ibe buthuntu ngelixa isika iitshiphusi. Emva kokuba i-milling cutter ibuthuntu ukuya kwinqanaba elithile, ukuba iyaqhubeka isetyenziswa, iya kukhokelela ekwandeni okukhulu kwamandla okusila kunye nobushushu bokusika, kwaye inani lokunxiba le-milling cutter liya kwanda ngokukhawuleza, ngaloo ndlela lichaphazela umatshini. ukuchaneka kunye nomgangatho womphezulu kunye nesantya sokusetyenziswa komsiki wokusila.

Indawo yokugqoka isixhobo iyenzeka ikakhulu ngaphambili nangasemva komgca wokusika kunye nommandla wayo. Ukunxiba kwe-milling cutter ikakhulu kukunxiba ngasemva kunye nomda we-blade.

1. Izinto ezibangela ukunxiba komsiki wokuguba

Ezona zizathu ziphambili zokunxiba i-milling cutter kunxitywa ngoomatshini kunye nokunxiba kwe-thermal.

1. Isinxibo sikamatshini: Isinxibo sikamatshini sikwabizwa ngokuba yi-abrasive wear. Ngenxa yamanqaku amancinci anzima kumphezulu wokukhuhlana kweetshiphusi okanye i-workpieces, ezifana ne-carbides, i-oxides, i-nitrides kunye namaqhekeza akhiweyo, iimpawu ze-groove zobunzulu obuhlukeneyo ziqingqwe kwisixhobo, okukhokelela ekunxiweni komatshini. Ubunzima bezinto zokusebenza, amandla amakhulu amaqhekeza anzima ukukrazula umphezulu wesixhobo. Olu hlobo lokunxiba lunempembelelo ecacileyo kwizixhobo zensimbi zesixhobo esinesantya esiphezulu. Ukuphucula umgangatho wokusila we-milling cutter kunye nokunciphisa ixabiso le-roughness ye-surface yangaphambili, ngasemva kunye ne-cut edges, enokuthi icuthe isantya sokugqoka i-mechanical cutter.

2. Ukunxiba kwe-Thermal: Ngexesha lokugaya, iqondo lokushisa liyanyuka ngenxa yesizukulwana sokusika ukushisa. Ubunzima besixhobo buyancitshiswa ngenxa yenguqu yesigaba esibangelwa ukunyuka kweqondo lokushisa, kunye nesixhobo sesixhobo sinamathele kwi-chip kunye ne-workpiece kwaye ithathwe ngokubambelela, okubangelwa ukugqoka i-bonding; phantsi kwesenzo sokushisa okuphezulu, izinto ze-alloy zezixhobo zesixhobo kunye nezixhobo zokusebenza zisasazeka kwaye zitshintshe enye kwenye. , iimpawu zomatshini zesixhobo ziyancitshiswa, kwaye ukuchithwa kwe-diffusion kwenzeka phantsi kwesenzo sokungqubuzana. Oku kunxitywa kwezinto zokusika ezibangelwa kukusika ubushushu kunye nokunyuka kwamaqondo obushushu ngokudibeneyo kubizwa ngokuba kukunxitywa kwe-thermal.

Okwesibini, inkqubo yokunxiba ye-milling cutter

Njengezinye izixhobo zokusika, ukuguga kwabasiki be-milling kukhula ngokuthe ngcembe ngokunyuka kwexesha lokusika. Inkqubo yokunxiba inokwahlulwa ibe ngamanqanaba amathathu:

1. Inqanaba lokuqala lokunxiba: Eli nqanaba linxiba ngokukhawuleza, ngakumbi ngenxa yokuba iincopho zeconvex eziveliswa ngamanqaku okusila kumphezulu wevili lokusila kunye neebhulu ezikwi-blade zicolwa ngokukhawuleza ngexesha elifutshane emva kokuba i-milling cutter iloliwe. Ukuba i-burr inzulu, ixabiso lokunxiba liya kuba likhulu. Ukuphucula umgangatho obukhali we-milling cutter, kwaye usebenzise i-grinding okanye i-whetstone ukupholisa i-edge yokusika kunye nangaphambili nangemuva, enokunciphisa ngokufanelekileyo inani lokunxiba kwinqanaba lokuqala lokunxiba.

2. Inqanaba lokunxiba eliqhelekileyo: Kule nqanaba, ukunxiba kuncinci, kwaye inani leengubo landa ngokulinganayo kwaye lizinzile ngokunyuka kwexesha lokusika.

3. Inqanaba lokunxiba elikhawulezayo: Emva kokuba i-milling cutter isetyenziswe ixesha elide, i-blade iba buthuntu, amandla okusila ayanda, iqondo lobushushu lokusika liyenyuka, iimeko zokusila ziba mandundu, izinga lokunxiba le-milling cutter linyuka kakhulu, izinga lokunxiba liyanda. kabukhali, kunye nesixhobo ilahleko Rapid yokusika isakhono. Xa usebenzisa i-cutter yokugaya, kufuneka kugwenywe ukuba i-milling cutter inxiba kweli nqanaba.

3. Umgangatho wobuthuntu bokusika umsiki

Kumsebenzi wangempela, ukuba i-cutter yokugaya inenye yezi meko zilandelayo, oko kuthetha ukuba i-cutter yokugaya i-blunt: ixabiso le-roughness yomgangatho womhlaba owenziwe ngomatshini mkhulu kakhulu kunokuqala, kwaye amabala aqaqambileyo kunye nezikali zivela phezulu; iqondo lokushisa lokusika liye landa kakhulu, kwaye iitshiphusi Umbala utshintsha; amandla okusika ayanda, kwaye kwanokungcangcazela kwenzeka; umva okufutshane nomgca wokusika ngokucacileyo unxibile, kwaye nesandi esingaqhelekanga senzeka. Ngeli xesha, i-milling cutter kufuneka isuswe ukuze ilole, kwaye ukugaya akukwazi ukuqhubeka, ukwenzela ukuba ugweme ukuguga kakhulu okanye umonakalo kwi-milling cutter.
