Iimpawu ze-milling cutter

Abasiki bokugayaziza kwiimilo ezininzi kunye neesayizi ezininzi.Kukho nokukhethwa kweengubo, kunye ne-rake angle kunye nenani leendawo zokusika.

• Ubume:Iimilo ezininzi ezisemgangathweni zeumsiki wokugayazisetyenziswa kushishino namhlanje, ezichazwe ngokubanzi ngezantsi.
• Iifluti / amazinyo:Iifleyiti zentsimbi yokusila yimijelo enzulu ye-helical ebaleka inyuka isisiki, ngelixa iblade ebukhali ecaleni komphetho wembande yaziwa ngokuba lizinyo.Izinyo lisika izinto, kwaye iichips zale nto zitsalwa phezulu ngefluti ngokujikeleza komsiki.Phantse kusoloko kukho izinyo elinye kwifleyiti nganye, kodwa abanye abasiki banamazinyo amabini kwifleyiti nganye.Amaxesha amaninzi, amazwiimbandekwayeizinyozisetyenziswa ngokutshintshanayo.Abasiki bokucola banokuba nezinyo ukusuka kwelinye ukuya kwabaninzi, kunye nesibini, esithathu kunye nesine sesona sixhaphakileyo.Ngokuqhelekileyo, okukhona umsiki unamazinyo amaninzi, kokukhona inokususa izinto ngokukhawuleza.Ngoko, a4-izinyo cutterinokususa izinto ngesantya esiphindwe kabini se-aumsiki wamazinyo amabini.
• I-engile ye-Helix:Iifleyiti zesisiki sokusila ziphantse zihlale zi-helical.Ukuba iifluti zithe tye, izinyo lonke liza kuchaphazela imathiriyeli ngaxeshanye, libangele ukungcangcazela kunye nokunciphisa ukuchaneka kunye nomgangatho womphezulu.Ukubeka iifluti kwi-engile kuvumela izinyo ukuba zingene kwizinto eziphathekayo ngokuthe ngcembe, ukunciphisa ukungcangcazela.Ngokuqhelekileyo, abasiki abagqibayo bane-angle ephezulu yerake (i-helix eqinile) ukunika ukugqitywa okungcono.
• Ukusika embindini:Abanye abasiki bokungqusha banokugrumba ngokuthe ngqo ezantsi (bagxume) kwimathiriyeli, ngelixa abanye bengakwazi.Oku kungenxa yokuba amazinyo abanye abasiki abahambi yonke indlela ukuya embindini wobuso besiphelo.Nangona kunjalo, aba basiki banokusika ukuya ezantsi nge-engile yama-45 degrees okanye njalo.
• Ukugqwesa okanye ukugqiba:Iindidi ezahlukeneyo ze-cutter ziyafumaneka ukusika izinto ezininzi, ukushiya umphezulu ombi (urhabaxa), okanye ukususa inani elincinci lezinto, kodwa ushiye umgangatho olungileyo (ukugqiba).Umsiki orhabaxainokuba namazinyo arhabaxa okophula iitshiphu zemathiriyeli zibe ngamaqhekeza amancinci.La mazinyo ashiya indawo erhabaxa ngasemva.Umsiki wokugqiba unokuba nenani elikhulu (amane nangaphezulu) amazinyo okususa izinto ngononophelo.Nangona kunjalo, inani elikhulu leefluti lishiya indawo encinci yokususa i-swarf ngokufanelekileyo, ngoko ke ayifanelekanga kakhulu ukususa izinto ezininzi.
• Iingubo:Izixhobo ezifanelekileyo zokugqoka izixhobo zinokuba nempembelelo enkulu kwinkqubo yokusika ngokunyusa isantya sokusika kunye nobomi besixhobo, kunye nokuphucula ukugqitywa komphezulu.Idayimani yePolycrystalline (PCD) yiyaleko eqinileyo esetyenziswa kuyoabasikiekufuneka imelane nokunxitywa kwe-abrasive ephezulu.Isixhobo esigqunywe ngePCD sinokuhlala ukuya kutsho kumaxesha angama-100 ubude kunesixhobo esingagqunywanga.Nangona kunjalo, i-coating ayikwazi ukusetyenziswa kumaqondo okushisa angaphezu kwama-600 degrees C, okanye kwiintsimbi ze-ferrous.Izixhobo zokulungisa i-aluminium ngamanye amaxesha zinikwa i-coating ye-TiAlN.Ialuminiyam yintsimbi encangathi encangathi, kwaye iyakwazi ukuzidibanisa emazinyweni ezixhobo, iwenze abonakale buthuntu.Nangona kunjalo, ithambekele ekubambeleleni kwi-TiAlN, ivumela isixhobo ukuba sisetyenziswe ixesha elide kwi-aluminium.
• I-Shank:I-shank yicylindrical (non-fluted) inxalenye yesixhobo esetyenziselwa ukubamba kunye nokuyibeka kwindawo yesibambi sesixhobo.I-shank inokuthi ijikeleze ngokugqibeleleyo, kwaye ibanjwe yi-friction, okanye inokuba ne-Weldon Flat, apho i-screw iseti, eyaziwa ngokuba yi-grub screw, yenza uqhagamshelwano lokunyusa i-torque ngaphandle kokutyibilika kwesixhobo.Idayamitha inokwahluka kububanzi bendawo yokusika isixhobo, ukuze ikwazi ukubanjwa sisibambi sesixhobo esisemgangathweni.§ Ubude beshanki bunokufumaneka ngobukhulu obahlukeneyo, kunye namanqina amafutshane (malunga ne-1.5x idayamitha) ebizwa ngokuba “yi-stub”, inde (i-5x idayamitha), ubude obongezelelweyo (i-8x idayamitha) kunye nobude obongezelelweyo (i-12x ububanzi).
