Mu gulu lalikulu la zida zomwe zasintha chitukuko cha anthu, kuyambira pa chiwongola dzanja chodzichepetsa mpaka pa microchip yovuta, chida chimodzi chimaonekera chifukwa cha kupezeka kwake ponseponse, kusavuta, komanso mphamvu zake zazikulu:chobowola chopotoka cha shank yolunjikaChitsulo chozungulira ichi chopanda chinyengo, chokhala ndi mipata yake yozungulira yopangidwa bwino, ndicho chida chachikulu chopangira ndi kusonkhanitsa, chomwe chimapezeka m'malo onse ogwirira ntchito, mafakitale, ndi nyumba padziko lonse lapansi. Ndicho kiyi chomwe chimatsegula kuthekera kwa zinthu zolimba, zomwe zimatilola kulumikizana, kulumikiza, ndi kupanga molondola kwambiri.
Ngakhale kuti kuboola ndi kwakale kwambiri, kuyambira nthawi zakale pogwiritsa ntchito miyala yakuthwa ndi mauta, chobowola chamakono chopindika ndi chinthu chomwe chinapangidwa ndi Industrial Revolution. Chinthu chatsopano chinali kupanga chitoliro chake chozungulira, kapena spiral groove. Ntchito yayikulu ya groove iyi ndi iwiri: kugawa bwino ma chips (zinyalala) kutali ndi malo odulira ndikutuluka m'bowo lomwe likubooledwa, ndikulola madzi odulira kufika pamalo okhuzana. Izi zimaletsa kutentha kwambiri, zimachepetsa kukangana, ndikutsimikizira dzenje loyera komanso lolondola. Ngakhale spiral grooves imatha kukhala ndi 2, 3 kapena kuposerapo, kapangidwe ka 2-flute kakadali kofala kwambiri, kamapereka mulingo woyenera wa liwiro lodulira, kuchotsa ma chips, ndi mphamvu ya bit.
Kusinthasintha kwa chitsulo chobowola cholunjika cha shank twist kumaphatikizidwa m'dzina lake. "Chobowola cholunjika" chimatanthauza mapeto a cylindrical a chitsulo chomwe chimamangiriridwa mu chuck ya chida. Kapangidwe kake konsekonse ndi mphamvu yake yayikulu, zomwe zimathandiza kuti chigwirizane ndi makina osiyanasiyana. Chikhoza kumangiriridwa bwino mu chobowola chosavuta chamanja, chida champhamvu chobowola chamagetsi chogwiritsidwa ntchito m'manja, kapena makina akuluakulu obowola osasuntha. Kuphatikiza apo, ntchito yake imapitirira kupitirira zida zobowola zapadera; ndi gawo lokhazikika la zida mu makina opera, ma lathe, komanso malo opangidwa ndi makompyuta apamwamba kwambiri. Kuphatikizika kumeneku kumapangitsa kuti chikhale chilankhulo chachikulu padziko lonse lapansi chopangira makina.
Kapangidwe ka zinthu zachobowoleraYapangidwa kuti igwirizane ndi ntchito yake. Chipangizo chodziwika kwambiri ndi High-Speed Steel (HSS), chida chapadera chomwe chimasunga kuuma kwake komanso luso lake ngakhale kutentha kwambiri komwe kumapangidwa chifukwa cha kukangana. Zidutswa za HSS ndi zolimba kwambiri komanso zotsika mtengo, zoyenera kuboola matabwa, pulasitiki, ndi zitsulo zambiri. Pa ntchito zovuta kwambiri, monga kuboola zinthu zokwawa monga miyala, konkire, kapena zitsulo zolimba kwambiri, zidutswa zoboola za carbide zokhala ndi timizere ta carbide kapena zolimba zimagwiritsidwa ntchito. Carbide, chinthu chophatikizika chokhala ndi tinthu ta tungsten carbide tolumikizidwa ndi cobalt, ndi cholimba kwambiri kuposa HSS ndipo chimapereka kukana kwakukulu kwa kuwonongeka, ngakhale kuti chimaphwanyikanso kwambiri.
Kuyambira pakusonkhanitsa zinthu za mumlengalenga mpaka kupanga mipando yabwino, chobowolera cholunjika cha shank twist ndi chofunikira kwambiri. Ndi umboni wa lingaliro lakuti zinthu zatsopano zomwe zimakhudza kwambiri nthawi zambiri zimakhala zomwe zimagwira ntchito imodzi yofunika kwambiri komanso yogwira ntchito bwino. Si chida chokha; ndi maziko omwe kupanga zinthu zamakono ndi luso la DIY zimamangidwira, dzenje limodzi lolondola nthawi imodzi.
