2 . nika motsi
Lokacin da kayan aikin niƙa da saman zoben rufewa suna motsawa dangane da juna, jimlar hanyoyin zamewar dangi na kowane aya akan saman zoben rufewa zuwa kayan aikin niƙa ya kamata su kasance iri ɗaya. Har ila yau, jagorancin motsi na dangi ya kamata ya kasance kullum yana canzawa. Canjin canjin yanayin motsi na yau da kullun yana hana kowane ƙwayar abrasive daga maimaita yanayin kansa a saman zoben rufewa, don kada ya haifar da alamun lalacewa a bayyane kuma yana haɓaka ƙaƙƙarfan farfajiyar zoben rufewa. Bugu da ƙari, ci gaba da canji na jagorancin motsi ba zai iya sa abrasive ya fi rarraba a ko'ina ba, don haka ana iya yanke ƙarfe a saman zoben rufewa.
Kodayake motsin niƙa yana da rikitarwa kuma yanayin motsi yana canzawa sosai, motsin niƙa koyaushe ana aiwatar da shi tare da haɗin haɗin kayan aikin niƙa da saman zoben rufewa. Ko da manual nika ko inji, da geometric siffar daidaito na sealing zobe surface ne yafi shafa ta geometric siffar daidaito na nika kayan aiki da nika motsi.
3. nika gudun
Da sauri motsin niƙa, mafi inganci da niƙa. The nika gudun ne da sauri, mafi abrasive barbashi wuce ta cikin surface na workpiece kowane lokaci naúrar, kuma mafi karfe da aka yanke.
Gudun niƙa yawanci 10 ~ 240m / min. Domin workpieces bukatar high nika daidaici, da nika gudun kullum ba ya wuce 30m/min. Gudun niƙa na shingen rufewa na bawul yana da alaƙa da kayan da aka rufe. The nika gudun na sealing surface na jan karfe da kuma jefa baƙin ƙarfe ne 10 ~ 45m / min; da sealing surface na taurare karfe da wuya gami ne 25 ~ 80m / min; da sealing surface na austenitic bakin karfe 10 ~ 25m / min.
4. matsa lamba nika
Ayyukan niƙa yana ƙaruwa tare da haɓakar matsa lamba, kuma matsa lamba na niƙa bai kamata ya zama babba ba, gabaɗaya 0.01-0.4MPa.
A lokacin da nika da sealing surface na Cast baƙin ƙarfe, jan karfe da kuma austenitic bakin karfe, da nika matsa lamba ne 0.1 ~ 0.3MPa; da sealing surface na taurare karfe da wuya gami ne 0.15 ~ 0.4MPa. Ɗauki ƙima mafi girma don ƙaƙƙarfan niƙa da ƙaramin ƙima don niƙa mai kyau.
5. Izinin niƙa
Tun da nika shine tsari na ƙarshe, adadin yankan yana da ƙananan. Girman iznin niƙa ya dogara ne akan daidaiton mashin ɗin da ƙarancin yanayin aikin da ya gabata. A karkashin yanayin tabbatar da kawar da alamun sarrafawa na tsarin da aka rigaya da kuma gyara kuskuren geometric na zoben rufewa, ƙananan izinin niƙa, mafi kyau.
Gabaɗaya filin rufewa ya kamata a yi ƙasa sosai kafin a niƙa. Bayan nika mai kyau, za a iya lapping surface na sealing kai tsaye, kuma mafi ƙarancin izinin niƙa shine: izinin diamita shine 0.008 ~ 0.020mm; izinin jirgin sama shine 0.006 ~ 0.015mm. Ɗauki ƙaramin ƙima lokacin da niƙa na hannu ko taurin abu ya yi girma, kuma ɗauki babban ƙima lokacin da injin niƙa ko taurin kayan ya yi ƙasa.
Wurin rufe jikin bawul ɗin ba shi da kyau a ƙasa da sarrafa shi, don haka ana iya amfani da juyi mai kyau. Bayan an gama juyawa, farfajiyar rufewa dole ne ta zama ƙasa mara kyau kafin a gama, kuma izinin jirgin sama shine 0.012 ~ 0.050mm.
