Ritenga rino maka hinahua whakarewa anga pokepokea aime nga ratonga oTe miihini CNC, maimoatanga wera me te maimoatanga mata.
Ko te rino hina, he rino maka hina ranei, he momo rino whakarewa he hanganga moroiti kauwhata. Ka whakaingoatia mo te tae hina o te whati ka puta. Ka whakamahia te rino hina mo nga whare he mea nui ake te pakari o te waahanga i te kaha o tona kaha, penei i nga poraka porotaka miihini whakangao o roto, nga whare papu, nga tinana takirere, nga pouaka hiko, nga pauna taumaha me nga whakarewa whakapaipai. He maha nga wa e whakamahia ana te kaha o te waiariki o te rino maka hina me te kaha o te upoko ki te hanga i nga taputapu tunu rino me nga rotors parai kōpae.
Ko te hanganga matū hei tiki i te hangahanga moroiti kauwhata ko te 2.5 ki te 4.0% waro me te 1 ki te 3% silicon ma te taumaha. Ka noho pea te graphite ki te 6 ki te 10% o te rōrahi o te rino hina. He mea nui a Silicon ki te hanga i te rino hina, he rereke ki te rino ma, na te mea he huānga whakapumau graphite i roto i te rino whakarewa, ko te tikanga ka awhina i te koranu ki te whakaputa kauwhata hei utu mo nga carbide rino; i te 3% silicon tata karekau he waro e mau ana ki te whakakotahitanga matū me te rino.
Ko te kauwhata he ahua o te tawerewere ahu-toru. I roto i nga waahanga e rua, i te mea ka puta mai he mata whakakoi i raro i te karu, ka puta nga tawerewere kauwhata hei raina pai. Ko nga pito o nga tawerewere he kakari o mua; no reira, he pakarukaru. Ko te noho o nga tawerewere kauwhata ka ngawari te miihini i te rino Kerei na te mea ka ngawari te pakaru ki nga tawerewere kauwhata. He pai rawa te kaha o te rino hina, no reira ka whakamahia te nuinga hei turanga mo nga taputapu miihini.

Anga whakarewa whakarewaka kiia hoki ko te tukanga ka whakakikoruatia i mua i te kirikiri o te kirikiri kapia, te anga wera mo te whakarewatanga o te anga, te mahi whakarewa matua ranei. Ko te mea hanga matua ko te kirikiri kapia phenolic i mua i pania, he nui ake te utu i te onepu matomato me te onepu kapia furan. I tua atu, kaore e taea te whakamahi i tenei kirikiri.
Ko te tukanga whakarewa kirikiri whakamaroke-whaiaro a Furan (te tukanga nobake) e whakamahi ana i te kirikiri whakakikoruatia o te kapia furan hei hanga i te pokepokea ai. Whai muri i te whakaranu i te onepu taketake (he kirikiri kua whakahokia mai ranei), he kapia furan wai me te whakakorikori wai kia rite, ka whakakiia ki roto ki te pouaka matua (he pouaka kirikiri ranei), katahi ka whakakaha kia whakapakeketia ki roto i te pokepokea ai ki roto i te pouaka matua (he kirikiri ranei). pouaka) i te pāmahana rūma. Na ka hanga te pokepokea makanga matua makanga ranei, e kiia nei ko te whakamaroke-whaiaro pouaka makariri-matua (matua), tikanga whakapakeke-whaiaro ranei (matua).
No te mea i hanga te pokepokea ai i te pāmahana rūma, me te kore hiahia ki te wera, ka kiia hoki te makanga kirikiri whakapakeke-whaiaro te tukanga makanga kore-tunu. Ka taea te wehea te tikanga whakamaroke-whaiaro ki roto i te kapia furan waikawa-catalyzed me te tikanga whakapakeke i te kirikiri kirikiri phenolic, te tikanga whakapakeke i te kirikiri urethane me te tikanga whakapakeke-whaiaro phenolic monoester.
Hei kirikiri pouaka makariri e whakapakeke ana, ko te onepu kapia furan te kirikiri kirikiri tuatahi me te tino whakamahia i tenei wa i roto i te hangahanga Hainamana. Ko te nui o te kapia e tapirihia ana ki roto i te kirikiri hanga ko te tikanga 0.7% ki te 1.0%, a ko te nui o te kapia taapiri i roto i te kirikiri matua ko te tikanga 0.9% ki te 1.1%. Ko te ihirangi o te aldehyde kore utu i roto i te kapia furan kei raro iho i te 0.3%, a kua heke etahi wheketere ki raro i te 0.1%. I roto i nga hangahanga i Haina, kua eke te onepu whakamaroke-whaiaro o te furan ki te taumata o te ao ahakoa te mahi whakaputa me te kounga o te mata o nga whakarewanga.

Ko nga Painga o te Furan Resin pania kirikiri-whakapakeke-whakapakeke-whakaekea te Maka:
1) Whakapai ake i te tika o te ahu o te whakarewanga me te taratara o te mata.
2) Ko te whakamaroke o te kirikiri (matua) kaore e hiahiatia kia whakamaroke, ka taea te whakaora i te kaha, ka taea hoki te whakamahi i nga pouaka rakau iti, kirihou ranei me nga tauira.
3) Ko te kirikiri whakapakeke-whaiaro he ngawari ki te taapiri me te pakaru, ngawari ki te horoi i nga whakarewa, ka taea te hangarua i te kirikiri tawhito me te whakamahi ano, ka tino whakaitihia te kaha o te mahi o te hanga matua, te whakatauira, te taka o te onepu, te horoi me etahi atu hononga, me he ngawari ki te mohio ki te miihini, ki te miihini ranei.
4) Ko te hautanga papatipu o te kapia i roto i te onepu ko te 0.8%~2.0% anake, a he iti te utu matawhānui o nga rauemi mata.
Na te mea he maha nga painga ahurei kua whakahuahia ake nei e te tikanga whakapakeke-whaiaro, kaore i te whakamahia te tikanga whakapakeke-whaiaro mo te hanga matua, engari ka whakamahia ano hoki mo te whakarewanga whakarewa. He tino pai mo te waahanga kotahi me te hanga puranga iti, a ka taea te whakaputa i te rino, te whakarewa maitai me te whakarewa kore-ferrous. Ko etahi o nga whare hangahanga Hainamana kua whakakapi katoa i te uku kirikiri kirikiri maroke, kirikiri kirikiri sima, me etahi waahanga whakakapinga mo te kirikiri karaihe wai.
