Mtundu wa Mphero Yomaliza

Pali magulu angapo akuluakulu a zida zogayira kumapeto ndi nkhope, monga kudula pakati poyerekeza ndi osadula pakati (kaya mpheroyo ingadulidwe mozama); ndi kugawa m'magulu malinga ndi chiwerengero cha zitoliro; ndi ngodya ya helix; ndi zinthu; komanso ndi zinthu zokutira. Gulu lililonse likhoza kugawidwanso malinga ndi momwe limagwiritsidwira ntchito komanso mawonekedwe apadera.

Ngodya yodziwika kwambiri ya helix, makamaka podula zitsulo, ndi 30°. Pomalizamphero zomaliza, nthawi zambiri zimakhala zozungulira zolimba kwambiri, zokhala ndi ma helix angles 45° kapena 60°.Mphero zolunjika za flute end(helix angle 0°) imagwiritsidwa ntchito pazinthu zapadera, monga kugaya mapulasitiki kapena zinthu zopangidwa ndi epoxy ndi galasi. Ma flute end mill olunjika ankagwiritsidwanso ntchito kale podula zitsulo Carl A. Bergstrom wa Weldon Tool Company asanapange helical flute end mill mu 1918.

Pali ma end mills okhala ndi variable flute helix kapena pseudo-random helix angle, ndi discontinuous flute geometries, kuti athandize kuswa zinthu m'zidutswa zazing'ono podula (kukonza tchipisi chotulukamo ndikuchepetsa chiopsezo cha kugwedezeka) ndikuchepetsa kugwiritsa ntchito zida pazidutswa zazikulu. Mapangidwe ena amakono amakhalanso ndi zinthu zazing'ono monga corner chamfer ndi chipbreaker. Ngakhale kuti ndi okwera mtengo kwambiri, chifukwa cha kapangidwe kovuta komanso njira zopangira, mongamphero zomalizazimatha kukhala nthawi yayitali chifukwa cha kuchepa kwa kuwonongeka ndikuwongolera zokolola mumakina othamanga kwambiri(HSM) ntchito.

Zikuchulukirachulukira kuti mphero zokhazikika zachikhalidwe zilowe m'malo mwa zoyikamo zotsika mtengo kwambiri.zida zodulira(zomwe, ngakhale poyamba zimakhala zodula kwambiri, zimachepetsa nthawi yosinthira zida ndipo zimathandiza kuti m'malo mwa chida chonsecho musinthe mosavuta m'malo mwa chida chonsecho chomwe chawonongeka kapena chosweka).

Ma end mill amagulitsidwa mu imperial ndi metric shank komanso cutting diameter. Ku USA, metric imapezeka mosavuta, koma imagwiritsidwa ntchito m'masitolo ena okha osati m'masitolo ena; ku Canada, chifukwa chakuti dzikolo lili pafupi ndi US, ndi chimodzimodzi. Ku Asia ndi Europe, metric diameter ndi yofanana.
