Indlela yemveli yokwenza imingxuma ye-crankshaft kukusebenzisa isixhobo esidityanisiweyo sokudinwa kumatshini okhethekileyo wokulungisa. I-blade nganye ihambelana nendawo yokucubungula ehambelanayo ukugqiba umngxuma we-crankshaft. Xa kusetyenzwa, kuyimfuneko ukusebenzisa inkxaso encedisayo kwisixhobo esikruqulayo. Le ndlela yokucubungula ayisebenzi ngokubanzi. Kwiziko lomatshini. Umgca wokuvelisa oguquguqukayo webhloko yesilinda ikakhulu usebenzisa iziko lomatshini. Kweyona nkqubo yokusetyenzwa, kuba umngxuma we crankshaft ubunzulu obukhulu ukuya kumngxuma womlinganiselo wedayamitha, ubude bomngxuma bungaphezulu kwe 400mm. Kwaye, i-overhang ihlala inde, ukuqina akubi, kulula ukubangela ukungcangcazela, kunzima ukuqinisekisa ukuchaneka komgangatho kunye nokuchaneka kobume bomngxuma obhorekileyo. Inkqubo ekruqulayo ye-U inokusombulula ezi ngxaki zingentla kakuhle.

Okubizwa ngokuba yi-turning ekruqulayo yindlela yomatshini ende yomngxuma apho izixhobo zikruqukile ukusuka kwiindawo ezimbini zokugqibela zenxalenye kwiziko lomatshini elithe tye. Inkqubo yokujika ekruqulayo ye-workpiece igxininiswe kube kanye kwaye itafile ijikelezwe nge-180 °. Undoqo wale ndlela Nciphisa ubude bokutya. I-U-turn boring igwema inkxaso encedisayo kunye nokuthintelwa kwisantya sokujikeleza kwe-shaft enesithukuthezi, enokunyusa isantya sokusika; ibha enesithukuthezi ine-overhang emfutshane kunye nokuqina okulungileyo, okunokuphucula ukuchaneka kokudika kwaye kukulungele abasebenzi.

Ngenxa yokuba i-axes yemingxuma emibini edikayo ayinakuhambelana ngokupheleleyo ngexesha lokucubungula, impazamo yesalathiso sokujikeleza kwetafile ye-180 °, impazamo yentshukumo yetafile kunye nempazamo yokuqina kwentshukumo yokutya inokukhokelela ngokuthe ngqo kwimpazamo ye-coaxiality ye-axis yomngxuma. Ke ngoko, ukulawula impazamo ye-coaxiality ye-U-turn boring sisitshixo sokulawula ukuchaneka komatshini. Ukuze kuqinisekiswe ukuchaneka kokulungiswa, ukuchaneka kwezixhobo zokucubungula kufuneka kuphuculwe, kwaye ukuchaneka kokumisa kunye nokuphindaphinda ukuchaneka kwendawo yokusebenza kunye ne-spindle kufuneka ibe phezulu. Ukongezelela, sinokuthatha amanyathelo kwinkqubo yokuphelisa okanye ukunciphisa ezi zinto ezimbi ezichaphazela i-coaxiality, ukwenzela ukuba kuphuculwe ukuchaneka kwe-coaxiality ye-boring ye-U-turn. Ukusebenzisa i-high-precision ephezulu kunye ne-high-effective machining center edibeneyo kunye ne-U-turn edikayo inkqubo yokucubungula iindidi zemingxuma emide kunye neenkqubo ze-coaxial hole zingathatha ngcono inkqubo ye-U-turn ekruqulayo.

Kwimingxuma ye-crankshaft efuna ukuchaneka okuphezulu komatshini, itekhnoloji yokucubungula i-honing nayo iyafuneka, oko kukuthi, isixhobo sijikeleza kumngxunya we-crankshaft, kwaye ukucutshungulwa kwe-honing kuyaphindwa. Inkqubo ye-honing yile ilandelayo: i-honing e-coarse isetyenziselwa ukususa inani eliseleyo, ukuphelisa amanqaku amnandi, ukuphucula ukuchaneka kwemilo yomngxuma, kunye nokunciphisa uburhabaxa bomngxuma; ihoning ecolekileyo isetyenziselwa ukuphucula ngakumbi ukuchaneka kwe-dimensional kunye nokuchaneka kwemilo yomngxuma, kunye nokunciphisa uburhabaxa bomphezulu, I-uniform cross-texture yenziwa kumphezulu we-cylinder bore; i-flat-top honing isetyenziselwa ukususa iincopho zeempawu ze-groove yomnatha, ukwenza umphezulu we-flat-top, ukuseka isakhiwo se-flat-top net phezu komngxuma, kunye nokuphucula izinga lokuxhasa umphezulu womngxuma. Ukuhonjiswa kwemingxuma ye-crankshaft kukulungiswa okuthe tye. Ukuqwalasela iimfuno zokuchaneka kwe-F kunye ne-B yemingxuma ye-cylinder crankshaft, akukho mfuneko yokuhombisa imingxuma ye-crankshaft, kwaye akukho zixhobo zokuhombisa ezifunekayo.
