Mphepete mwa mphero yomaliza ndi pamwamba pa cylindrical, ndipo mphepete mwa mphero yomwe ili kumapeto kwake ndi mphepete mwa mphero yachiwiri. Mphero yomaliza yopanda mphepete mwa mphero singathe kuchita kayendedwe ka chakudya motsatira njira yozungulira ya chodulira mphero. Malinga ndi muyezo wa dziko lonse, m'mimba mwake mwa mphero yomaliza ndi 2-50 mm, zomwe zingagawidwe m'mitundu iwiri: mano olimba ndi mano opyapyala. M'mimba mwake wa 2-20 ndi m'lifupi mwa shank yowongoka, ndipo m'lifupi mwa 14-50 ndi m'lifupi mwa shank yopapatiza.
Mafakitale odulira okhazikika amapezeka ndi mano okhuthala komanso osalala. Chiwerengero cha mano a fakitale yodulira okhwima ndi 3 mpaka 4, ndipo ngodya ya helix β ndi yayikulu; chiwerengero cha mano a fakitale yodulira okhwima ndi 5 mpaka 8, ndipo ngodya ya helix β ndi yocheperako. Zipangizo za gawo lodulira ndi chitsulo champhamvu kwambiri, ndipo shank ndi chitsulo 45.
Pali mitundu yambiri ya zida zodulira mphero, zomwe zimagwiritsidwa ntchito pa makina wamba odulira mphero ndi makina odulira a CNC pokonza mipata ndi mizere yolunjika, komanso pokonza mabowo, mitima, ndi mawonekedwe/mizere pamwamba pa malo odulira mphero ndi makina oboola.
Zipangizo zodulira mphero nthawi zambiri zimagawidwa m'magulu awa:
1. Chodulira mphero chathyathyathya, pogaya bwino kapena kugaya mopanda mphamvu, kugaya mipata, kuchotsa malo ambiri opanda kanthu, kugaya bwino malo ang'onoang'ono opingasa kapena mizere;
2. Chodulira mphuno ya mpirapokonza malo opindika pang'ono ndi kumaliza; odulira ang'onoang'ono amatha kumaliza kugaya ma chamfer ang'onoang'ono pamalo otsetsereka/makoma owongoka.
3. Chodulira mphero chosalala chili ndikugwedeza, yomwe ingagwiritsidwe ntchito pogaya mopanda mphamvu kuti ichotse malo ambiri opanda kanthu, komanso ingagwiritsidwenso ntchito kugaya bwino ma chamfer ang'onoang'ono pamalo osalala bwino (monga momwe zilili pamalo otsetsereka).
4. Kupanga zodulira mphero, kuphatikizapo zodulira za chamfering, zodulira zogayira zooneka ngati T kapena zodulira ng'oma, zodulira mano, ndi zodulira zamkati za R.
5. Chodulira cha chamfering, mawonekedwe a chodulira chamfering ndi ofanana ndi a chamfering, ndipo amagawidwa m'magawo odulira mphero ozungulira ndi odulira chamfering.
6. Chodulira chooneka ngati T, chidebe chogayira chooneka ngati T;
7. Chodulira mano, chodula mitundu yosiyanasiyana ya mano, monga magiya.
8. Chodulira khungu cholimba, chodulira mphero chopangidwa kuti chidulire aluminiyamu ndi zitsulo zamkuwa, zomwe zimatha kukonzedwa mwachangu.
Pali zinthu ziwiri zomwe zimagwiritsidwa ntchito podulira mphero: chitsulo chothamanga kwambiri ndi carbide yolimba. Poyerekeza ndi yoyamba, yachiwiriyo ili ndi kuuma kwakukulu komanso mphamvu yodulira yamphamvu, zomwe zimatha kuwonjezera liwiro ndi kuchuluka kwa chakudya, kupititsa patsogolo zokolola, kupangitsa kuti choduliracho chisawonekere, komanso kukonza zinthu zovuta kugwiritsa ntchito monga chitsulo chosapanga dzimbiri/titanium alloy, koma mtengo wake ndi wokwera, ndipo mphamvu yodulira imasintha mwachangu. Ngati choduliracho chili chosavuta kuswa.
