I. Kodi Kugaya Kwambiri Ndi Chiyani?
High-Feed Milling (yofupikitsidwa ngati HFM) ndi njira yotsogola yamphero mu makina amakono a CNC. Cholinga chake chachikulu ndi "kuzama kwakung'ono komanso kuchuluka kwa chakudya". Poyerekeza ndi njira zachikhalidwe zophera, ukadaulo uwu umagwiritsa ntchito kuya kwakung'ono kwa axial (nthawi zambiri kuyambira 0.1 mpaka 2.0 mm) komanso kuchuluka kwakudya kwa dzino (mpaka 5-10 nthawi ya mphero yachikhalidwe), kuphatikiza ndi liwiro la spindle, kuti akwaniritse chakudya chodabwitsa.
Chisinthiko cha lingaliro ili la processing lagona mu kusintha kwake kokwanira kwa njira yodulira mphamvu, kutembenuza mphamvu yowononga yowononga yopangidwa mu mphero yachikhalidwe kukhala mphamvu ya axial yopindulitsa, potero kumapangitsa kuti ntchito yothamanga kwambiri komanso yogwira ntchito ikhale yotheka. Mutu wogaya chakudya mwachangu ndi chida chapadera chomwe chidapangidwa kuti chikwaniritse njirayi ndipo chakhala chida chofunikira kwambiri pakupangira nkhungu zamakono, zamlengalenga, ndi mafakitale amagalimoto, pakati pa ena.
II. Mfundo Yogwira Ntchito yaWodula Wakudyetsa Kwambiri
Chinsinsi cha chodulira mphero chapamwamba kwambiri chagona mu kapangidwe kake kakang'ono kakang'ono kakang'ono. Mosiyana ndi ocheka mphero omwe amakhala ndi ngodya yayikulu ya 45 ° kapena 90 °, mutu wodula mphero nthawi zambiri umatenga ngodya yaying'ono ya 10 ° mpaka 30 °. Kusintha kumeneku kwa geometry kumasintha komwe mphamvu yodulira imayendera.
Njira yosinthira makina: Tsamba likakumana ndi chogwirira ntchito, mawonekedwe ang'onoang'ono opangira ngodya amachititsa kuti mphamvu yodulirayo iloze ku mbali ya axial (motsatira mbali ya chida cha chida) m'malo molunjika (perpendicular to axis) monga mphero yachikhalidwe. Kusintha uku kumabweretsa zotsatira zazikulu zitatu:
1. Kugwedezeka kwamphamvu kwamphamvu: Mphamvu yayikulu ya axial imakoka chodulira "ku" shaft yayikulu, kupangitsa chida chodulira - shaft system kukhala yokhazikika. Izi zimalepheretsa kugwedezeka ndi kugwedezeka, zomwe zimathandiza kudula bwino ngakhale pansi pazifukwa zazikulu.
2. Mphamvu yoteteza makina: Mphamvu ya axial imatengedwa ndi kukankhira kwa shaft yayikulu yamakina. Mphamvu yake yonyamula ndi yokwera kwambiri kuposa ya ma radial bearings, motero kuchepetsa kuwonongeka kwa shaft yayikulu ndikukulitsa moyo wa zida.
3. Mphamvu yowonjezera chakudya: Imathetsa malire a kugwedezeka, kupangitsa chidacho kuti chizitha kudya zakudya zambiri pa dzino. Kuthamanga kwa chakudya kumatha kufika 3 mpaka 5 nthawi ya mphero wamba, ndi liwiro lalikulu lomwe limafikira 20,000 mm / min.
Mapangidwe anzeru amakinawa amathandizira mutu wogaya chakudya mwachangu kuti ukhalebe ndi kuchuluka kwachitsulo chochotsa zitsulo pomwe amachepetsa kwambiri kugwedezeka, ndikuyika maziko opangira zinthu zapamwamba kwambiri.
III. Ubwino waukulu ndi Makhalidwe aWodula Wakudyetsa Kwambiri
1. Kukonza bwino kwambiri: Ubwino wodziwika kwambiri wa chodulira chodula kwambiri ndikuchotsa zitsulo (MRR). Ngakhale kuya kwa axial kudula kumakhala kozama, kuthamanga kwambiri kwa chakudya kumakwaniritsa kuperewera kumeneku. Mwachitsanzo, pamene makina wamba gantry mphero ntchito mofulumira chakudya mphero mutu pokonza chida zitsulo, liwiro chakudya akhoza kufika 4,500 - 6,000 mm/mphindi, ndi mlingo kuchotsa zitsulo ndi 2 - 3 nthawi apamwamba kuposa odula miyambo mphero.
2. Ubwino wapamwamba kwambiri: Chifukwa cha kudula kosalala kwambiri, mphero yofulumira imatha kukwaniritsa kutha kwapamwamba, komwe kumafika ku Ra0.8μm kapena kupitilira apo. Nthawi zambiri, pamwamba kukonzedwa pogwiritsa ntchito mofulumira chakudya mphero mitu akhoza mwachindunji ntchito, kuthetsa theka-amamaliza ndondomeko ndi kwambiri kufupikitsa ndondomeko kupanga.
3. Zodabwitsa zopulumutsa mphamvu: Kafukufuku akuwonetsa kuti kugwiritsa ntchito mphamvu pogaya chakudya mwachangu ndi 30% mpaka 40% poyerekeza ndi mphero zakale. Mphamvu yodulira imagwiritsidwa ntchito bwino pakuchotsa zinthu m'malo mogwiritsidwa ntchito pakugwedezeka kwa chida ndi makina, kukwaniritsa kukonza kobiriwira.
4. Ikhoza kuwonjezera kwambiri moyo wautumiki wa dongosolo lachida: Njira yodulira yosalala imachepetsa kukhudzidwa ndi kuvala pa chida, ndipo moyo wa chida ukhoza kuwonjezeka ndi oposa 50%. Mawonekedwe amphamvu otsika amachepetsanso kulemedwa kwa spindle ya chida cha makina, ndikupangitsa kuti ikhale yoyenera kwambiri pamakina akale osakhazikika kapena pamiyeso yayikulu.
5. Ubwino wokonza mbali zokhala ndi mipanda yopyapyala: Mphamvu yamagetsi yaying'ono kwambiri imatheketsa chodula mphero kuti chikhale chosankha bwino pokonza zigawo zopyapyala komanso zopunduka mosavuta (monga zida zomangira mumlengalenga, nkhungu zamagalimoto). The mapindikidwe workpiece yafupika ndi 60% -70% poyerekeza ndi mphero chikhalidwe.
Kufotokozera kwazomwe zimagwiritsidwa ntchito pazakudya zodula kwambiri:
Mukamagwiritsa ntchito chodulira chophatikizira chachikulu chokhala ndi mainchesi 50mm ndikukhala ndi masamba 5 ku makina a P20 chida chitsulo (HRC30):
Kuthamanga kwa spindle: 1,200 rpm
Mlingo wa chakudya: 4,200 mm / min
Kuzama kwa Axial: 1.2mm
Kuzama kwa radial: 25mm (chakudya chakumbali)
Kuchotsa kwachitsulo: Kufikira 126 cm³ / min
IV. Chidule
Chodulira mphero yayikulu si chida chabe; imayimira lingaliro lapamwamba lokonzekera. Kupyolera mu luso lopanga makina, limasintha kuipa kwa kudula mphamvu kukhala ubwino, kukwaniritsa kusakanikirana kwachangu, kuthamanga kwambiri, ndi kukonza bwino kwambiri. Kwa mabizinesi opangira makina omwe akukumana ndi kukakamizidwa kuti achulukitse bwino komanso kukwaniritsa zofunikira pakukonza kwapamwamba, kugwiritsa ntchito mwanzeru ukadaulo wapamutu wa feed feed mosakayika ndi njira yabwino yopititsira patsogolo mpikisano.
Ndi chitukuko chosalekeza cha ukadaulo wa CNC, zida za zida ndi pulogalamu ya CAM, ukadaulo wogaya chakudya mwachangu udzapitilirabe kusinthika, ndikupereka chithandizo champhamvu chaukadaulo pakusintha kwanzeru ndikukweza makampani opanga zinthu. Nthawi yomweyo phatikizani mutu wodula mphero mwachangu munjira yanu yopangira ndikuwona kusintha kwa kukonza bwino!
