Lub milling cutter yog ib qho cuab yeej tig nrog ib lossis ntau cov hniav siv rau milling. Thaum lub sij hawm ua hauj lwm, txhua tus hniav cutter intermittently txiav tawm ntau tshaj ntawm workpiece. Cov mills kawg yog siv rau kev ua cov dav hlau, cov kauj ruam, grooves, tsim cov chaw thiab txiav workpieces ntawm cov tshuab milling.
Raws li hom khoom, End mills tau muab faib ua:
① HSS kawg mills:
kuj hu ua high-speed steel, nrog mos hardness. High-speed steel cutters yog pheej yig thiab muaj zog toughness, tab sis lawv lub zog tsis siab thiab lawv yooj yim tawg. Qhov kub hardness ntawm high-speed steel milling cutters yog 600.
② Carbide kawg mills:
Carbide (tungsten steel) muaj cov khoom zoo heev xws li zoo thermal hardness, hnav tsis kam, zoo zog thiab toughness, tshav kub tsis kam, corrosion kuj, thiab lwm yam., tshwj xeeb tshaj yog, lub siab hardness thiab hnav kuj tseem nyob twj ywm tsis hloov txawm nyob rau ntawm 500 degrees, thiab lub hardness yog tseem siab heev ntawm 1000 degrees.
③ Ceramic kawg mills:
Kuj tseem hu ua oxidation kawg mills, nws muaj qhov nyuaj siab heev, kub tsis kam mus txog 1200 degrees, thiab tsis tshua muaj zog compressive. Txawm li cas los xij, nws yog nkig heev yog li lub zog tsis siab, yog li qhov txiav tsis tuaj yeem loj dhau. Yog li ntawd, nws yog qhov tsim nyog rau kev ua tiav kawg lossis lwm yam khoom siv uas tsis yog-hlau ua cov khoom siv zoo heev.
④ Superhard khoom kawg mills:
Nws yog zoo heev nyob rau hauv cov nqe lus ntawm hardness, hnav tsis kam, thiab kub kuj. Nws muaj toughness txaus thiab tuaj yeem tiv taus kub txog 2000 degrees. Nws yog qhov tsim nyog dua vim tias nws yog nkig heev thiab tsis muaj zog. Kev ua tiav kawg.
