I. Chii chinonzi High-Feed Milling?
High-Feed Milling (yakapfupikiswa seHFM) inzira yepamberi yekugaya mune yemazuva ano CNC machining. Chinhu chayo chepakati ndeche "kudzika kudiki uye kukwira kwekudya". Zvichienzaniswa nemaitiro echinyakare ekukuya, tekinoroji iyi inoshandisa kudzika kweaxial kudiki kwazvo (kazhinji kubva pa0.1 kusvika 2.0 mm) uye yakanyanya kukwirisa per-zino rekudya (kusvika ka5-10 nguva yekugaya yechinyakare), yakasanganiswa nekumhanya kwespindle, kuti iwane chikafu chinokatyamadza.
Chimiro cheshanduko yeiyi pfungwa yekugadzirisa iri mukushandurwa kwayo kwakazara kwekutungamira kwesimba rekucheka, kushandura iyo inokuvadza radial simba inogadzirwa mukugaya kwechinyakare kuita inobatsira axial simba, nekudaro zvichiita kuti kukurumidza-kumhanya uye kushanda zvakanaka kugoneke. Musoro wekugayira chikafu chakanyanya chigadziriso chakagadzirirwa kuita zano iri uye chave chinhu chakakosha kugadzirisa mukugadzira mold yemazuva ano, aerospace, uye maindasitiri emotokari, pakati pevamwe.
II. The Working Principle of theHigh-Feed Milling Cutter
Chakavanzika kuseri kwechigayo chekudya chepamusoro chiri mune yayo yakasarudzika diki main angle dhizaini. Kusiyana nevechinyakare vanocheka kugaya vane 45 ° kana 90 ° main angle, iyo inokurumidza feed milling cutter musoro inowanzotora hombe hombe ye10 ° kusvika 30 °. Shanduko iyi mu geometry inoshandura kutungamira kwesimba rekucheka.
Mechanical shanduko maitiro: Kana blade ikasangana neworkpiece, iyo diki main rake angle dhizaini inoita kuti simba rekucheka rinyanye kunongedza kune axial gwara (pamwe neaxis yemutumbi wechombo) pane kutenderera radial (perpendicular kune axis) sekugaya kwechinyakare. Shanduko iyi inoguma nemhedzisiro mitatu yakakosha:
1. Vibration suppression effect: The hombe axial force inokweva cutter disc "kuna" kune main shaft, zvichiita kuti cutter tool - main shaft system ive in a tense state. Izvi zvinonyatso kudzvanya vibration uye flutter, zvichigonesa kucheka kwakatsetseka kunyangwe pasi pemamiriro makuru epamusoro.
2. Muchina kudzivirira maitiro: Iyo axial simba inotakurwa nekusundirwa kweiyo shaft huru yemuchina. Kutakura kwayo kwakakwira zvakanyanya kupfuura iyo yeradial bearings, nekudaro ichidzikisa kukuvadzwa kune main shaft uye kuwedzera hupenyu hwechishandiso.
3. Kuwedzeredza kwekudya: Inobvisa zvisingakwanisi kuzunguzika, zvichiita kuti chishandiso chibate mazinga akanyanya ekudya pazino. Iyo yekumhanyisa yekudya inogona kusvika katatu kusvika ku5 nguva yeyakajairika, nekumhanya kwakanyanya kunosvika pamusoro pe20,000 mm/min.
Iyi inyanzvi yekugadzira dhizaini inogonesa kukurumidza kugaya musoro kuchengetedza yakakwira simbi yekubvisa chiyero uku ichideredza zvakanyanya kucheka vibration, kuisa hwaro hwepamusoro-yemhando yepamusoro kugadzirisa.
III. Izvo Zvikuru Zvakanakira uye Hunhu hweiyoHigh-Feed Milling Cutter
1. Kushanda kwepamusoro-soro: Kunyanya kukoshesa kwepamusoro-soro yekucheka kwekucheka kwesimbi ndiyo yakatanhamara yekubvisa simbi (MRR). Kunyangwe iyo axial yekucheka kudzika kwakati kudzika, iyo yakanyanya kukwirisa yekudyisa kumhanya inozadzisa kushomeka uku. Semuyenzaniso, kana muchina wegantry wakajairika ukashandisa chigayo chekukurumidza kugadzira simbi yemidziyo, kukurumidza kwekudya kunogona kusvika 4,500 - 6,000 mm/min, uye chiyero chekubvisa simbi chakapetwa ka2 - 3 kupfuura chevanhu vanocheka.
2. Hunhu hwakanaka hwepamusoro: Pamusana pekucheka kwakanyanyisa, kukurumidza kudya kwekudya kunogona kubudirira kupedzisa kwepamusoro, kazhinji kusvika kuRa0.8μm kana kunyange yakakwirira. Muzviitiko zvakawanda, nzvimbo dzakagadziriswa nekushandisa nekukurumidza milling misoro inogona kushandiswa zvakananga, kubvisa iyo semi-yekupedzisira maitiro uye kupfupisa zvakanyanya maitiro ekugadzira.
3. Zvinoshamisa kuchengetedza simba: Tsvagiridzo inoratidza kuti kushandiswa kwesimba kwekukurumidza kugayo kuri 30% kusvika 40% kuderera pane kuya kwechinyakare. Simba rekucheka rinoshandiswa nemazvo pakubvisa zvinhu pane kupedzwa mukuzunguzika kwechishandiso nemuchina, kuwana chokwadi chegirinhi kugadzirisa.
4. Inogona kuwedzera zvakanyanya hupenyu hwebasa regadziriro yezvishandiso: Iyo yakatsetseka yekucheka inoderedza kukanganiswa uye kupfeka pachishandiso, uye hupenyu hwekushandisa hunogona kuwedzerwa neinopfuura 50%. Iyo yakaderera radial simba hunhu inodzikisirawo mutoro pamuchina wekushandisa spindle, ichiita kuti inyanyokodzera michina yechinyakare isina kukwana kuoma kana kune yakakura-span yekugadzirisa mamiriro.
5. Zvakanakira kugadzira mativi akatetepa-ane madziro: Iyo yakanyanya kudiki-diki simba reradial inogonesa iyo yepamusoro yekugaya yekucheka kuti ive sarudzo yakanaka yekugadzira dzakatetepa-madziro uye kuremara zviri nyore (senge aerospace structural components, automotive body mold parts). Iyo deformation ye workpiece yakaderedzwa ne 60% -70% kana ichienzaniswa neyechinyakare milling.
Reference yeyakajairwa kugadzirisa ma paramita eiyo yakakwira feed milling cutter:
Paunenge uchishandisa chigayo chepamusoro chekucheka chine dhayamita ye50mm uye chine mashizha mashanu kumuchina P20 chishandiso simbi (HRC30):
Spindle kumhanya: 1,200 rpm
Chiyero chekudya: 4,200 mm / min
Axial yekucheka kudzika: 1.2mm
Radial yekucheka kudzika: 25mm (padivi chikafu)

IV. Summary
Chigayo chepamusoro chekucheka hachingori chishandiso; inomiririra pfungwa yepamusoro yekugadzirisa. Kuburikidza nehungwaru hwemakina dhizaini, inoshandura zvipingamupinyi zvekucheka simba kuita zvakanakira, kuwana musanganiswa wakakwana wekumhanya kukuru, kunyatsoita basa, uye yakakwirira chaiyo kugadzirisa. Kune ma mechanika ekugadzirisa mabhizinesi akatarisana nekumanikidzwa kuti awedzere kushanda zvakanaka uye kusangana nepamusoro-mhando yekugadzirisa zvinodiwa, iko kunzwisisika kushandiswa kweiyo kukurumidza feed milling musoro tekinoroji pasina mubvunzo isarudzo yehungwaru yekusimudzira kukwikwidza.
Nekuenderera mberi kwekuvandudza tekinoroji yeCNC, zvishandiso zvematurusi uye CAM software, tekinoroji yekukurumidza yekugaya icharamba ichishanduka, ichipa rutsigiro rwakasimba rwehunyanzvi hwekushandurwa kwehungwaru uye kusimudzira indasitiri yekugadzira. Pakarepo sanganisa iyo inokurumidza kugaya yekucheka musoro mune yako yekugadzira maitiro uye unzwe inoshandura mhedzisiro yekunyatso gadzirisa!
