Ma screw Machine Drill Bits ali ndi kutalika kwaufupi kuti azitha kulimba bwino komanso kulondola pobowola. Akulimbikitsidwa pobowola zitsulo, chitsulo chosapanga dzimbiri, magalimoto akuluakulu ndi nyumba zoyenda.
Chobowolera cha Makina Okulungira chomwe chimatchedwa "chobowolera cha stub". Chitsulo cholemera champhamvu kwambiri. Chokonzedwa ndi oxide wakuda, malo ogawanika a madigiri 135. Chitoliro chachifupi ndi kutalika konse kumawonjezera kulimba kwawo, zomwe zimapangitsa kuti mabowo akhale olondola bwino komanso kuti zida zikhale ndi nthawi yayitali.
Chitoliro chachifupi ndi kutalika konsekonse kumawonjezera kulimba, zomwe zimapangitsa kuti dzenje likhale lolondola bwino komanso kuti chipangizocho chikhale ndi nthawi yayitali.
Chitsulo chapamwamba cha cobalt chothamanga kwambiri chomwe chimagwira ntchito yolimba kwambiri komanso yolimba nthawi yayitali.
Kuboola kolondola chifukwa cha malo ogawanika a madigiri 135
Akulimbikitsidwa kuboola zipangizo zolimba kwambiri monga chitsulo chosapanga dzimbiri, titaniyamu, chitsulo cha manganese, mbale ya zida ndi iconel
Ubwino
★Kutalika Kochepa, Kolimba Kwambiri
Ma screw Machine Drills (omwe amadziwikanso kuti stub kapena stubby drills) ali ndi kapangidwe kakafupi komanso kolimba komwe kamagwira ntchito bwino pazinthu zosiyanasiyana m'magulu achitsulo ndi chitsulo.
Kuboola makina okulungira ndi otchuka m'mafakitale a magalimoto ndi zomangamanga. Nthawi zambiri amagwiritsidwa ntchito pokonza makina okulungira ndi okulungira komwe kulibe malo okwanira ogwirira ntchito.
★Ma Drill Osiyanasiyana Komanso Olimba
Ma screw Machine Drills ndi ofanana ndi chitsulo champhamvu kwambiri, koma ali ndi cobalt yambiri kuti agwire bwino ntchito akamadula zitsulo zolimba monga chitsulo chosapanga dzimbiri kapena nickel alloys.
Amapangidwa motsatira Aerospace Standard 907 yokhala ndi mfundo yogawa madigiri 135 imadziyimira yokha ndipo imachepetsa kugwedezeka. Makulidwe ang'onoang'ono kuposa 1/16 ndi akulu kuposa 1/2 ali ndi mfundo yokhazikika ya madigiri 118.
★Gawo Logawanika Lolemera
Makina Opangira Zokulungira a Drill America ali ndi malo olemera opatukana a madigiri 135 kuti azidzipangira okha komanso kuchepetsa mphamvu. Makulidwe ang'onoang'ono kuposa 1/16 ndi akulu kuposa 1/2 ali ndi malo okhazikika a madigiri 118.
