Njira yachikhalidwe yopangira mabowo a crankshaft ndikugwiritsa ntchito chida chophatikizira chotopetsa pamakina apadera opangira. Tsamba lililonse limafanana ndi malo opangirako kuti amalize dzenje la crankshaft. Mukakonza, ndikofunikira kugwiritsa ntchito chithandizo chothandizira chida chotopetsa. Njira yopangira iyi nthawi zambiri sigwira ntchito. Pa Machining Center. Mzere wosinthika wa cylinder block makamaka umagwiritsa ntchito malo opangira makina. Mu ndondomeko yeniyeni yokonza, chifukwa dzenje la crankshaft ndilozama kwambiri mpaka m'mimba mwake, kutalika kwa dzenje kumaposa 400mm. Ndipo, overhang nthawi zambiri imakhala yayitali, kukhazikika kumakhala koyipa, ndikosavuta kuyambitsa kugwedezeka, ndizovuta kutsimikizira kulondola kwazithunzi ndi mawonekedwe a dzenje lobowoka. Njira yotopetsa ya U-turn imatha kuthetsa mavuto omwe ali pamwambawa bwino.

Otchedwa kutembenuka wotopetsa ndi yaitali dzenje Machining njira imene zida wotopetsa kuchokera mbali ziwiri mapeto a gawo pa yopingasa Machining pakati. Njira yotopetsa ya workpiece imamangidwa kamodzi ndipo tebulo limazungulira 180 °. Cholinga cha njirayi ndikuchepetsa kutalika kwa chakudya. U-turn wotopetsa umapewa chithandizo chothandizira komanso kuletsa kuthamanga kwa shaft yotopetsa, yomwe imatha kukulitsa kuthamanga; bala yotopetsa imakhala ndi nthawi yayitali komanso yokhazikika bwino, yomwe imatha kuwongolera kulondola kotopetsa komanso yabwino kwa ogwira ntchito.

Chifukwa nkhwangwa za mabowo awiri obowola sizingakhale mwangozi panthawi yokonza, kulakwitsa kwa tebulo la 180 °, kulakwitsa kwa kayendetsedwe ka tebulo ndi zolakwika zowongoka za kayendedwe ka chakudya kungayambitse kulakwitsa kwa coaxiality kwa bowo. Chifukwa chake, kuwongolera cholakwika cha coaxiality cha U-turn wotopetsa ndiye chinsinsi chowongolera kulondola kwa makina. Kuti zitsimikizire kulondola kwa kukonza, kulondola kwa zida zopangirako kuyenera kukonzedwa bwino, ndipo kulondola kwa malo ndi kubwereza mobwerezabwereza kulondola kwa tebulo logwirira ntchito ndi spindle ziyenera kukhala zapamwamba. Kuphatikiza apo, titha kuchitapo kanthu kuti tithetse kapena kuchepetsa zinthu zoyipazi zomwe zimakhudza coaxiality, kuti tipititse patsogolo kulondola kwa coaxiality kwa wotopetsa wa U-turn. Kugwiritsa ntchito malo opangira makina olondola kwambiri komanso ochita bwino kwambiri ophatikizidwa ndi njira yotopetsa ya U-turn pokonza mabowo aatali ndi ma coaxial hole system amatha kugwiritsa ntchito bwino njira yotopetsa ya U-turn.

Kwa mabowo a crankshaft omwe amafunikira kulondola kwa makina apamwamba, ukadaulo wopangira honing umafunikanso, ndiye kuti, chidacho chimazungulira mu dzenje la crankshaft, ndikubwereza honing. Njira ya honing ndi motere: honing coarse amagwiritsidwa ntchito kuchotsa ndalama zotsalira, kuchotsa zizindikiro zabwino zosasangalatsa, kukonza mawonekedwe olondola a dzenje, ndi kuchepetsa roughness pamwamba pa dzenje; honing zabwino ntchito zina patsogolo kulondola dimensional ndi mawonekedwe olondola a dzenje, ndi kuchepetsa roughness pamwamba, A yunifolomu mtanda kapangidwe aumbike pamwamba pa yamphamvu anabowola; honing-top honing kumagwiritsidwa ntchito kuchotsa nsonga za nsonga za ukonde, kupanga malo otsetsereka, kukhazikitsa ukonde wathyathyathya pamwamba pa dzenje, ndikuwongolera mlingo wothandizira pamwamba pa dzenje. The honing wa mabowo crankshaft ndi yopingasa processing. Poganizira zolondola za mabowo a F ndi B silinda ya crankshaft, palibe chifukwa cholimbira mabowo a crankshaft, ndipo palibe zida za honing zomwe zimafunikira.
