Hanyar gargajiya na machining crankshaft ramukan shine yin amfani da kayan aiki mai ban sha'awa mai ban sha'awa akan na'urar sarrafawa ta musamman. Kowane ruwa ya dace da daidaitaccen matsayi na sarrafawa don gama ramin crankshaft. Lokacin sarrafawa, wajibi ne a yi amfani da goyon bayan taimako don kayan aiki mai ban sha'awa. Wannan hanyar sarrafawa gabaɗaya baya amfani. A kan machining center. Layin samar da sassauƙa na shingen silinda yafi amfani da cibiyar mashin ɗin. A cikin ainihin tsari na sarrafawa, saboda ramin crankshaft babban zurfin zurfin ramin rabo ne, tsayin rami ya fi 400mm. Kuma, overhang sau da yawa yana da tsayi, rashin ƙarfi ba shi da kyau, yana da sauƙi don haifar da girgiza, yana da wuya a tabbatar da daidaiton girman da siffar siffar rami mai gundura. Tsarin U-juya mai ban sha'awa zai iya magance matsalolin da ke sama da kyau.

Abin da ake kira juyawa mai ban sha'awa shine hanya mai tsayi mai tsayi wanda kayan aikin ke gundura daga saman biyu na ƙarshen ɓangaren akan cibiyar injin kwance. Juya m tsari na workpiece ne clamped sau ɗaya kuma tebur yana juya 180 °. Ma'anar wannan hanyar ita ce Rage tsawon ciyarwa. U-juya m yana guje wa tallafin taimako da ƙuntatawa akan saurin jujjuyawar shinge mai ban sha'awa, wanda zai iya ƙara saurin yankewa; mashaya mai ban sha'awa yana da ɗan gajeren lokaci da kuma tsauri mai kyau, wanda zai iya inganta daidaito na m kuma ya dace da ma'aikata.

Saboda gatari na biyu m ramukan ba zai iya zama cikakken daidaituwa a lokacin aiki, da index kuskure na tebur juyawa na 180 °, da tebur motsi kuskure da straightness kuskure na ciyar motsi iya kai tsaye kai ga coaxiality kuskure na rami axis. Saboda haka, sarrafa kuskuren coaxial na U-turn m shine mabuɗin don sarrafa daidaiton injin. Don tabbatar da daidaiton aiki, ana buƙatar haɓaka madaidaicin kayan aikin sarrafawa, kuma ana buƙatar daidaita daidaiton matsayi da maimaita daidaiton madaidaicin ma'aunin aiki da sandal ɗin ya zama babba. Bugu da ƙari, za mu iya ɗaukar matakai a cikin tsari don kawar da ko rage waɗannan abubuwa masu banƙyama da suka shafi coaxiality, don inganta daidaiton coaxial na rashin tausayi na U-turn.

Don ramukan crankshaft waɗanda ke buƙatar daidaiton mashin ɗin, ana kuma buƙatar fasahar sarrafa honing, wato, kayan aikin yana juyawa cikin ramin crankshaft, kuma ana maimaita sarrafa honing. Tsarin honing shine kamar haka: ana amfani da honing mai laushi don cire ragowar adadin, kawar da alamomi masu ban sha'awa, inganta daidaiton siffar rami, da kuma rage girman ramin; ana amfani da honing mai kyau don ƙara haɓaka daidaiton girman girman da daidaiton siffar ramin, da kuma rage ƙarancin ƙasa, An samar da nau'in giciye iri ɗaya akan saman kwandon silinda; Ana amfani da honing mai lebur don cire kololuwar alamomin tsagi, samar da shimfidar saman saman, kafa tsarin gidan yanar gizo mai lebur akan saman ramin, da haɓaka ƙimar tallafi na saman ramin. Honing na crankshaft ramukan aiki ne a kwance. Yin la'akari da daidaitattun buƙatun F da B Silinda crankshaft ramukan, babu buƙatar honing ramukan crankshaft, kuma babu kayan aikin honing da ake buƙata.
