Masiku ano, pali mitundu yambiri yobowola matabwa moti makasitomala ambiri sadziwa kuti ndi mtundu wanji womwe amafunikira.Ndime iyi ikupatsani malingaliro.
Zopotoka Zopotoka: Zobowola zokhota zimakhala ndi zibowo zachitsulo zozungulira komanso nsonga za mfundo.
Kukula kwa masamba ambiri obowola ndi akulu ngati zingwe zake. Zitoliro ziwiri za helical (zomwe nthawi zina zimatchedwa chip channels) zimathamanga ndi magawo awiri mwa atatu a utali wake, zopindika mozungulira shank ngati mikwingwirima pamtengo wa ometa.
Mtengo wa ma twist drill ndi wotsika mtengo kuposa ma bits ena, koma dzenje la ma bits opangidwa siwolondola. Amagwiritsidwa ntchito nthawi zambiri ndi kubowola pansi kuti atsimikizire kulondola. simungagwiritse ntchito ndi liwiro lozungulira.Kuchita bwino kwa makina anu kudzakhalanso kochepa.
Ma twist drills ndi abwino kwa anthu odzilemba okha kapena ogwiritsa ntchito omwe zida zawo sizili zobwerera m'mbuyo.
Bits za Spade.Mabatani awa amawoneka ngati dzina lawo limatanthawuza: Chibowo chilichonse chachitsulo chimathera ndi tsamba la shovel.Fosholoyo ndi yathyathyathya ndi yosongoka pakati.Mfundoyi imagwira ntchito ngati chitsogozo cholowera pakati pa dzenje ndikuwongolera njira, koma kubowola kwakukulu kumachitidwa ndi honing kudula pamapewa a fosholo.
Chifukwa cha kapangidwe kake ka ma spade bits, ilibe luso losamutsa chip.Panthawi imodzimodziyo, chifukwa cha mapangidwe a ndege a m'mphepete mwa nyanja, nkhonya yabwino ya spade bit ndi yoipa kwambiri.
Chifukwa chake, pakulondola, zopangira zokumbira ndi zabwino kuposa zokhotakhota.Koma makina ake ochita bwino ayenera kukhala oipitsitsa kuposa onse.
Ma twist drills ndi abwino kwa anthu odzilemba okha omwe amagwiritsa ntchito zida zamagetsi.
Brad Point Drills: Pofuna kukwaniritsa zosowa zamakina othamanga kwambiri, brad point drill bit idapangidwa.Brad point drill bit imaphatikiza ubwino wa spade bit ndi twist drill.Pali pobowola pakati ngati kalozera, ndipo pali mbali ziwiri zodula mbali zonse kuti zitsimikizire kukula kwa dzenjelo.Ndipo ma brad point drill bits alinso ndi ma grooves ozungulira kuti awonjezere kuthekera koboola.Mapangidwe a shank ndikuwonetsetsa kuti atha kugwiritsidwa ntchito bwino pamakina a CNC.
Ndipo tapanganso ndikukhazikitsa mitundu yosiyanasiyana ya ma brad point drill bits kuti makasitomala azigwiritsa ntchito nthawi zosiyanasiyana.ZY kubowola pang'ono ndi oyenera otsika-liwiro (1000-3000S/min) Machining.KJ-2 kubowola pang'ono ndi oyenera sing'anga-liwiro (2000-4000S/mphindi) Machining.Zobowola za KJ-1 ndizoyenera makina othamanga kwambiri (3000-6000S/min).
Kubowola kwa Brad point ndiye chisankho chabwino kwambiri kwa makasitomala omwe ali ndi makina a CNC.
Countersink Drills.Ma biti opangidwa mwapadera amagulitsidwa omwe amabowola zomangira zamatabwa.Kubowola kwa Countersink kumakhala ndi mbiri yofananira ndi mawonekedwe a zomangira: Mabowo omwe amabowola amatha pang'onopang'ono kutalika kwa screw, kenako amakulitsa, kulola kuti mitu ya zomangira ikhazikike (countersunk) mumitengo. Ndi yoyenera matabwa a CNC. makina.
Zithunzi za ForstnerTinthu tanzeru timeneti timabowola mabowo okhala ndi pansi.M'malo mokhala ndi nsonga yotsetsereka yomwe imatsatiridwa ndi m'mphepete mwake, Forstner bit imatsogozedwa ndi mkombero.Ngalande mu kubowola amachotsa dzenje la tchipisi ndi fumbi.Bowo lomwe limakhalapo limakhala ndi pansi pafupifupi lathyathyathya, longowonongeka ndi dzenje la 1/32-inch pakati pomwe choyambira chobowola chili.
Ma bits a Forstner ndi okwera mtengo, ndipo siwofunikira pa ntchito zambiri.Komabe, ndizofunikira kwa ena, monga mahinji okwera omwe amayenera kutsekeredwa pabowo lozungulira lomwe limangodutsa pang'onopang'ono pazitseko.(Ngati mutagwiritsa ntchito zokumbira pazifukwa zomwezo, mfundo yake ikanatulukira mbali ina, ndikuwononga pamwamba.) Ndi yoyenera makina opangira matabwa a CNC.
