He aha te take e uaua ai te keri i te maitai kore waikura mēnā ka pēhia mārire rawa—ā, he aha hoki te whakautu tika ehara i te mea ko te pēhi kaha noa iho.
I te wā e keri ana i ngā konganuku uaua, he mea whakamatautauria kia whakaitihia te pēhanga ki runga i te keri kia kore ai e pakaru te taputapu. Kāore taua whakaaro i te hē rawa: ka taea e te nui o te whāngai te whakakī i te mata keri.
Engari i te wā e keri ana i ngā maitai kore waikura austenitic pērā i te 304 me te 316, ka rerekē te pānga ki te whāngai māmā rawa. Ka huri tonu te keri engari ka uaua ki te uru ki roto i te mea mahi. Ka uaua haere te keri, ā, ka tere ake te pakaru o te taputapu.
Kāore pea te raruraru i te kounga maitai, i te pakeke rānei o te mata wiri anake. Tērā pea kei roto i tētahi āhuatanga rauemi e warewarehia ana: arā, ko te whakapakeketanga o te mahi.
1. He aha te Whakapakari Mahi?
Ka puta te whakapakeketanga mahi ina kaha ake te konganuku, ā, ka ātete ake ki te whakarerekētanga kirihou i muri i tōna whakarerekētanga. Ko ngā maitai kore waikura austenitic, tae atu ki ngā momo noa pēnei i te 304 me te 316, ka tino pāngia e tēnei whanonga.
I te wā e keri ana, ehara i te mea ko te tango i te konganuku anake te mahi a ngā taha tapahi. Ka whakapohehetia hoki e rātou te rauemi i roto me te taha o te rohe tapahi. Ka taea te whakapakeke i ētahi mahi tata ki te mata mīhini ahakoa i raro i ngā āhuatanga tapahi noa.
Ehara i te mea ko te whakakore i ngā tohu katoa o te whakapakeketanga o te mahi te whāinga. Engari kia mau tonu te whai hua o te tapahi, kia kore ai hoki e mirimiri, e pēhi tonu ki tētahi mata kua whakapēhia kētia.
Kaua e whakapoauautia ngā tikanga e rua:
• Ko te whakapakeketanga o te mahi te take matua o te whakarerekētanga kirihou. Kāore i rite ki te whakapakeketanga o te maitai mā te whakamahana.
• Ka taea e te wera nui rawa o te tapahi te whakatere i te pakaru o te taputapu, me te kino hoki o te mata tapahi, engari ehara i te wera anake te tino take o te whakapakeketanga o te totoro.
Ka taea e ēnei pānga te puta ngātahi, ka whakakaha ake i ngā āhuatanga tapahi kino, engari ehara i te tukanga ā-tinana kotahi.
2. He aha i uaua ai te keri i te whāngai iti rawa?
Kia angitu te keri, me tango tonu e ngā taha tapahi ngā rauemi, kia puta ai ngā maramara ka puta mā roto i ngā putorino. Ina iti rawa te whāngai tuturu mō ia hurihanga, ka rerekē pea te mahi tapahi.
Hipanga 1: Ka whakakapia te tapahi ki te mirimiri me te parau
Ki te iti rawa te matotoru o te maramara kāore anō kia tapahia, ka taea e te mata tapahi te tango i te iti o ngā rauemi. He tino raruraru tēnei ina kua tawhito, kua porotaka rānei te mata. Engari i te hanga maramara kia whai hua, ka nui ake te wā e pau ana i te wiri ki te mirimiri, te pēhi, te parau rānei ki te mata o te mea mahi.
E hurihuri tonu ana te wiri, engari ka pōturi te werohanga.
Hipanga 2: Ka rerekē haere te āhua o te mata
Mā te mirimiri me te parau tonu ka taea te whakapōturi i te āhua o te paparanga maitai kore waikura tata ki te mata. I roto i tētahi rauemi e ngāwari ana ki te whakapakeke, ka nui ake te uaua o te tapahi e whai ake nei. Tērā pea ka nui ake te ātete tapahi o te wiri i a ia e ngana ana ki te tango i te paparanga e pāngia ana.
Hipanga 3: Ka tere ake te pakaru o te mata tapahi
Ka tāpirihia te waku me te kawenga wera e te tapahi koretake. Mēnā he ngoikore hoki te whakamatao me te tango maramara, ka tere ake te pakaru o te mata tapahi. Kātahi ka kore e taea e te mata kua pakaru te hanga maramara ma, ka nui ake te tūponotanga o te mirimiri me te parau.
Tērā pea he huringa rahunga: Kāore i te rawaka te whāngai → He nui ake te miri me te parau → He nui ake te rerekētanga tata ki te mata → He uaua ake te tapahi → He tere ake te mau o te taha.
He tikanga rahunga pea tēnei, ehara i te raupapatanga e kore e taea te karo i roto i ngā mahi whāngai-iti katoa. Ka whakawhirinaki anō hoki te putanga ki te āhua o te keri, te āhua o te taputapu, te āhua o te rauemi, te pakari o te mīhini, te whakahinuhinu, me ētahi atu āhuatanga tapahi.
3. Kāore te Pēhanga Whāngai me te Whāngai ia Hurihanga i te ōrite
He mea nui tēnei rerekētanga nā te mea ehara te kupu "pēhi kaha ake" i te tūtohutanga miihini e tino tika ana.
Pēhanga whāngaiko te kaha tuaka e whakamahia ana hei pana i te wiri ki roto i te mea mahi. Ka tino kitea i roto i te wiri ā-ringa, i te wiri ā-ringa rānei.
Whāngai mō ia hurihangako te tawhiti tuaka tuturu ka nekehia e te wiri i te wā o te hurihanga katoa kotahi, e whakaatuhia ana i roto i ngā mirimita mō ia hurihanga (mm/hurihanga).
He hononga ēnei e rua, engari kāore e taea te whakawhiti. Ki te whakamahi i te wiri ringaringa, ka taea e te kaha kotahi te whakaputa i ngā tere weronga rerekē i runga i te koi, te whānui o te taputapu, ngā āhuatanga rauemi, me te whakatakotoranga mīhini. I runga i te mīhini CNC, i tētahi atu pūnaha whāngai whakahaere rānei, ko te whāngai ka whakaritea mā roto i ngā tawhā miihini kaua ki te pēhanga ringaringa.
Ko te pātai pai ake ehara i te "Kia pēhea te kaha o tā tātou pana?" Engari: "I tēnei tere tapahi me te whāngai i ia hurihanga, kei te tangohia tonutia e te wiri ngā rauemi mai i tēnei mea mahi?"
4. Kāore i te pai ake te nui o te whāngai i ngā wā katoa
Mena ka raru pea te iti o te whāngai, me whakamahi noa e ngā kaiwhakahaere te nui o te whāngai e taea ana? Kāo. Ka whakanuia e te nui o te whāngai te kaha tuaka me te kawenga tapahi. Kia hipa ake te kaha o te wiri, te mīhini, te whakatakotoranga rānei, ka puta pea he pakaru o te taha, he piko, he whati rānei.
| Āhua o te whāngai | Ngā hua pea |
| He iti rawa | Kāore i te rawaka te hanganga o ngā maramara, te nui o te mirimiri, me te kaha pea o te whakapakeketanga o ngā rauemi ngoikore. |
| Tika | Te hanganga maramara ōrite ake, te kaha tapahi kua whakahaeretia, me te tango maramara whai hua. |
| Teitei rawa | He nui rawa te kawenga, ka nui ake te mōrearea o te pakaru, te piko, te whati rānei o te wiri. |
Kāore he tautuhinga whāngai whānui mō ia mata keri HSS. Ko te whānuitanga e tika ana ka whakawhirinaki ki te diameter, te rauemi taputapu me te āhua o te taha, te rauemi mahi, te hohonu o te kōhao, te pakari o te mīhini, me ngā āhuatanga whakamatao. Kaua e whakamahia ngā taunakitanga whāngai mō ngā keri HSS me ngā keri carbide hei whakawhitiwhiti.
5. Me pēhea te whakaiti i te mōrearea whakapakeke mahi i roto i te keri maitai kore waikura
Kia mau tonu te whāngai tapahi e tika ana, e haere tonu ana
Mō ngā maitai kore waikura e ngāwari ana ki te whakapakeke i te mahi, kaua e tukua te wiri kia huri ki te mea mahi mō ngā wā roa me te kore e whai kiko te werohanga. Mō te keri ā-ringa, kia whai i te nekehanga pumau, whakahaeretia kaua te mirimiri roa i te hohonutanga kotahi. Mō te keri aunoa, whakatauritea ngā tawhā kua whakaritea ki te whāngai kua tūtohutia e te kaihanga taputapu mō ia hurihanga me ngā āhuatanga mahi tuturu.
Ki te kore e tika te tapahi a te wiri, kaua e akiaki noa kia hohonu ake. Kati me te tirotiro i te take.
Whakamahia he wiri koi me te āhua e tika ana
He pai ake te hanga maramara e te mata tapahi koi. Kāore te kaha e whakahokia mai ai te mahi tapahi o te wiri kua tawhito—ā, ka nui ake pea te tūponotanga o te pakaru.
Mō ētahi whakamahinga kowiri tira, ka taea e te āhua wehewehe 135° kua hoahoatia tika te āwhina i te whakaiti i te hikoi me te whakapai ake i te urunga poka. Heoi, kāore te koki anake e whakatau i te mahi; he mea nui anō hoki te koi o te taha, te āhua tukutuku, te pakari, me te ōritetanga o te hanga.
Whakatauritehia te tere tapahi ki te hinu whakahinuhinu me te whakamatao
Ka taea e te tere tapahi nui rawa te whakanui ake i te kawenga wera i runga i ngā taha tapahi. Mā te wai tapahi, te hinu rānei e tika ana ka āwhina i te whakahaere i te waku, te wera, me te tango maramara. Me aromatawai ngātahi te tere, te whāngai, me te whakamatao, kaua e whakarerekē takitahi i te taurangi kotahi.
Kia tūpato ki te tango i ngā maramara, inā koa i ngā kōhao hohonu ake.
I te piki haere o te hōhonutanga o te kōhao, ka uaua ake te tango i ngā maramara. Ka taea e ngā maramara kua mau te whakanui ake i te waku, te taipana, me te wera, ā, ka raru pea te taputapu.
Mēnā e tika ana, ka taea e te huringa keri-pōro, te huringa whakakore maramara rānei i hangaia kia pai ake ai te tukanga. Kāore te tango maramara i te rite ki te tuku i te keri kia noho, kia mirimiri ki te raro o te kōhao.
6. He aha te hiranga o tēnei ki ngā kaihoko me ngā kaituku o ngā mata keri
Whakaarohia tētahi amuamu a te kiritaki: "Ka tere te memeha o tēnei puranga mata wiri HSS ina kerihia he maitai kore waikura 304."
He mea tika kia tirotirohia ngā rauemi mata, te pakeketanga, te maimoatanga wera, me te kounga o te huri. Heoi, kāore te poto o te ora mahi e whakaatu ana i te hanga hē o te mata keri. Me whai mōhiohio anō hoki mō te whakamahinga o te tātaritanga rahunga whai hua.
I mua i te whakatau i ngā whakatau, pātai atu:
- • He aha te kounga me te āhua o te rauemi e keria ana te kowiri tira?
- • He aha te whānui o te keri, te kounga o ngā rauemi, te āhua o ngā pūwāhi, me te āhua o te taputapu?
- • He aha te tere o te porowhita, te tikanga whāngai, me ngā tawhā whāngai tuturu e whakamahia ana?
- • Kei te whakamahia te wai tapahi, ā, kei te rawaka te tango i te maramara?
- • Kei te memeha haere te wiri, kei te pakaru te taha, kei te pakaru ohorere rānei?
Mena he rerekētanga mahi ka taea te whakahoki i raro i ngā tikanga tapahi whakahaere kotahi, me arotahi te rangahau ki te kounga o ngā rauemi, te maimoatanga wera, te āhuahanga matatau, me te ōritetanga o te whakaputanga. I tetahi atu taha, ki te raru ētahi wiri e tika ana i raro i ngā tikanga whakahaere ōrite, me aro nui atu ki te tukanga miihini.
Kāore e taea e te kounga maitai kua whakapaitia te whakatika aunoa i ngā tawhā kāore i te tika. Hei tauira, tera pea ka whakaratohia e te M35 cobalt HSS he painga i roto i ētahi āhuatanga tapahi pāmahana teitei, engari kāore e taea e ia anake te whakakore i te korenga o te whāngai, te korenga o te maramara, te whakatakotoranga kore pumau rānei.
Whakatau: Ko te Tiaki i te Wiri Kāore i te Tika ki te Whakaiti i te Whāngai i ngā Wā Katoa
I roto i te keri kowiri tira, ehara i te mea he kōwhiringa haumaru ake te whāngai tūturu tino māmā. Ina mutu te hanga maramara o te keri, ka taea e te mirimiri me te parau tonu te whakapakeke i te mahi me te tere ake te pakaru o te mata hou.
Ko te otinga ehara i te pana kaha me te kore here. Engari ko te whakatū i ngā āhuatanga e taea ai e te wiri te tapahi mārire, te whakaputa maramara, me te whakakore pai i aua mea.
Ko te mahi pono o te mata keri HSS ka tīmata ki ngā rauemi pakari, te maimoatanga wera, te āhuahanga, me te hanga ōrite. Kei te whakamahinga anō hoki o te taputapu.
Me whai kounga hanga pono, me ngā tikanga tapahi tika hoki te mata wiri pai.
Mō tēnei raupapa
He raupapa hangarau a Why Drill Bits Fail nā tā mātou tīma hanga i tuhi. E arotahi ana ia tuhinga ki tētahi āhuatanga motuhake o te mahi a te mata o te wiri - mai i ngā rauemi mata ki te takai. He māmā noa te whāinga: āwhina i ngā kaihoko ki te mārama ki tā rātou e hoko ana, me ngā pātai hei pātai.
