Mtundu wa End Mill

Pali magulu angapo a zida zophera kumaso ndi kumaso, monga kudula pakati ndi kusadula pakati (kaya mphero imatha kudulidwa);ndi kugawa m'magulu mwa kuchuluka kwa zitoliro;ndi ngodya ya helix;mwa zinthu;ndi zokutira zinthu.Gulu lirilonse likhoza kugawidwanso ndi ntchito yapadera ndi geometry yapadera.

Mbali yotchuka kwambiri ya helix, makamaka kudula kwazitsulo zonse, ndi 30 °.Kwa kumalizamphero zomaliza, ndizofala kuwona zozungulira kwambiri, zokhala ndi ngodya za helix 45 ° kapena 60 °.Mphero zowongoka za chitoliro(helix angle 0 °) amagwiritsidwa ntchito mwapadera, monga mapulasitiki amphero kapena ma composites a epoxy ndi galasi.Makina omaliza a chitoliro chowongoka adagwiritsidwanso ntchito kale podula zitsulo asanatulutsidwe mphero yomaliza ya helical ndi Carl A. Bergstrom wa Weldon Tool Company mu 1918.

Pali mphero zokhala ndi ma helix a chitoliro chosinthika kapena ngodya ya pseudo-random helix, ndi ma geometries a chitoliro osapitilira, kuti athandizire kuswa zinthu kukhala tizidutswa tating'onoting'ono podula (kupititsa patsogolo kutulutsa kwa chip ndikuchepetsa chiwopsezo cha kudumphadumpha) ndikuchepetsa kukhudzidwa kwa zida pamabala akulu.Zopanga zina zamakono zimaphatikizaponso zinthu zazing'ono monga chamfer yamakona ndi chipbreaker.Ngakhale okwera mtengo, chifukwa cha zovuta kupanga ndi kupanga, mongamphero zomalizaimatha kukhala nthawi yayitali chifukwa cha kuchepa kwachangu komanso kukulitsa zokololamakina othamanga kwambiri(HSM) ntchito.

Zikuchulukirachulukirachulukira kuti mphero zolimba zachikhalidwe zisinthidwe ndikuyika zotsika mtengozida zodulira(omwe, ngakhale okwera mtengo poyambirira, amachepetsa nthawi yosinthira zida ndikulola kuti m'mphepete mwake muzitha kutha kapena kusweka m'mphepete mwake osati chida chonse).

Makina omaliza amagulitsidwa mumerial ndi metric shank ndi ma diameter.Ku USA, ma metric amapezeka mosavuta, koma amangogwiritsidwa ntchito m'masitolo ena a makina osati ena;ku Canada, chifukwa cha kuyandikira kwa dzikolo ku US, ndizofanana.Ku Asia ndi ku Europe, ma metric diameters ndi ofanana.
