Raupapa: He aha i hinga ai ngā mata wiri | Tuhinga 11
Ngā Kupumatua: te hoahoa o te putorino o te mata keri, te tango maramara, te koki porowhita o te mata keri, te putorino parabolic te mata keri, te matotoru o te tukutuku, te tākai maramara, te keri poka hōhonu HSS, te putorino paerewa me te putorino parabolic
I tirohia e te tuhinga whakamutunga o tēnei raupapa te āhua o te whakataurite i te koki pūwāhi ki ngā rauemi rerekē — te wā e kutikutihia ai te rauemi e te mata tapahi mai i te rauemi mahi. Ka tīmata tonu tēnei i muri i taua wā: ina tapahia he maramara, me wehe tonu i te kōhao. Ki te kore, ka mutu te hiranga o ngā mea katoa i runga ake — te taumata rauemi, te maimoatanga wera, te āhua pūwāhi — . Ka taea te hanga i tētahi mata mai i te M35 tūturu ka hurihia ki tētahi pūwāhi wehewehe 135° pukapuka, ā, ka rahua tonu, ki te kore e taea e te putorino te kawe tere i te maramara ki waho.
Te Wāhi e Haere ai te Maramara
Ka tangohia e te wiri hurihuri te rauemi i te pito, engari ka horoia taua rauemi i te taha o te putorino - te awa porowhita e hurihuri ana mai i te mata tapahi ki te kakau. Kāore te maramara e taka i waho o te kōhao i a ia anō; ka eke ki runga i taua awa, ka panaia e te hurihuri o te mata me te āhua o te pakitara o te putorino. E toru ngā taurangi e whakatau ana i te pai o te ekenga: te pari o te porowhita (te koki porowhita), te nui o te konganuku totoka e noho ana i waenganui o te mata (te matotoru o te tukutuku), me te nui o te wāhi tuwhera e tukuna ana e te awa putorino (te āhua putorino). Kāore e taea te whakapai ake i tētahi o ēnei i a ia anō - ka tauhokohoko rātou tetahi ki tetahi, ā, ko te taurite tika e whakawhirinaki ana ki te rauemi me te hohonu o te kōhao, ehara i te mea he tau "pai ake" kotahi.
Koki Hīkoi: Te Tere o te Whakarere ki te Kaha Matua
Ko te koki porowhita te koki porowhita o te putorino e inehia ana ki te tuaka o te wiri. Ka tere ake te pana o ngā maramara ki waho e te porowhita pari, ā, ka whakapoto i te roa o te mata tapahi e pā ana ki te rauemi i tētahi wā - engari ka whakanui ake hoki i te pana tuaka, ā, ka tangohia atu he rauemi mai i te tinana wiri, ka ngoikore ai te uho. Ka pupuri te porowhita papaku i te nui ake o te maitai i roto i te uho, ā, ka pai ake te mau i raro i te taipana, engari ka puhoi ake te neke o ngā maramara ki waho, ka noho hei herenga tūturu ina hohonu te kōhao.
Koia te take i taurite ai te koki porowhita ki te momo maramara, kaua e mau ki te tau kotahi. Ko ngā maramara roa, ngāwari — te momo i hangaia e ngā rauemi ngawari ake, ngāwari ake rānei — me whai porowhita pari ake kia kore ai e neke; ko ngā maramara poto, pakarukaru mai i ngā rauemi pakeke ake kāore e hiahia ki te pana kotahi, ā, ka nui ake te painga mai i te kaha matua tāpiri o te koki papaku ake. Kāore he koki porowhita "pai" whānui. Ko te koki anake e taurite ana ki te āhua o te hanganga o te maramara.
Matotoru o te Tukutuku: Pakari ki te Rūma Maramara
Ko te tukutuku te uho totoka e rere ana i waenganui o te mata, i waenganui i ngā putorino e rua. Mā tēnei ka kaha te wiri ki te huri — te kaha ki te ātete i te takahuri, te pakaru rānei i raro i te taipana tapahi. Kāore te matotoru o te tukutuku e pumau i te taha o te mata; ka āta whakawhāitihia, ka angiangi ake i te pito, ā, ka matotoru ake ki te kakau, kia pakari ai te mata i te wāhi e tino teitei ana te taipana kua kohia.
He tika te taupatupatu: he nui ake te tukutuku, he nui ake te kaha, engari he iti ake te wāhi i roto i te putorino hei nohoanga mō ngā maramara i a rātou e haere ana ki waho. Ki te tino pēhia te matotoru o te tukutuku, ka pakaru te hononga - ina whiti te tukutuku i te 40% o te whānui o te keri, ka kuiti rawa te awa o te putorino e toe ana ki te whakakore pono i ngā maramara, ā, ka neke te mōrearea mai i te "ka pakaru te mata" ki te "ka piri te mata, ka whati." Kāore i te tino kitea tēnei taipitopito i runga i tētahi pepa whakaritenga, engari koinei tētahi o ngā take e pakaru ai te keri i roto i te kōhao, kaua e whakapōuri i te pito.
Pūtorino Paerewa me te Pūtorino Parabolic: E rua ngā Whakautu ki te Raru Kotahi
E rua ā mātou momo putorino e hanga ana, ehara i te putanga "taketake" me te putanga "whakapai ake" o te wiri kotahi — he rerekē ngā mahi i hangaia ai.
He whaiti ake te awaawa me te tukutuku māmā ake o te putorino paerewa, he nui tēnei mō te nuinga o ngā keri whānui: he hohonutanga poka papaku ki te pakupaku, he roanga mahi noa iho, me ngā rauemi kāore e roa, e uaua ki te whakahaere. Ko te nuinga o ngā keri o ia rā ka taka ki tēnei wāhanga, ā, kāore he painga o te nui rawa o ngā whakaritenga i tua atu i tēnā.
Mā te putorino parabolic ka huaki ake taua awa. Ka hurihia te pakitara o te putorino kia whānui ake, kia piko ake, kia nui ake te wāhi o ngā maramara me te ara maeneene ake, me te porowhita tere ake e neke haere ana i a rātou. Ko te tikanga o te awa whānui ake ka taea hoki te whakamātotoru ake i te tukutuku i raro — tata ki te 25–50% o te diameter o te keri, ki te whakaritea ki te 12–25% o te putorino paerewa — kia whiwhi ai te mata i te kaha maramara me te kaha o te matua i te wā kotahi, kaua e hokohoko tetahi mo tetahi. Ko taua huinga ka taea e te putorino parabolic te pupuri i roto i ngā kōhao hohonu ake me ngā rauemi e whakaputa ana i ngā maramara roa ake, tonu ake, tae atu ki te maitai kore waikura, te parahi, me te konumohe, me te kore e hiahiatia kia werohia te kōhao i ngā wā katoa.
Ka ara ake te pana axial o taua tukutuku matotoru, koia te take e honoa ai ngā wiri putorino parabolic me tētahi pūwāhi wehe — te āhua 135° i kōrerotia i roto i te Tuhinga 9 — hei whakahoki i taua pana ki te taumata e taea te whakahaere.
I roto i tā mātou raina parabolic, e rua ngā whānui o te awaawa e tukuna ana e mātou. Mā te awaawa-V nui ake ka whakanui ake i te wāhi maramara me te tere o te tango, he mea e pai ana mō ngā rauemi uaua ki te mīhini engari he iti ake te maitai matua i muri. Mā te awaawa-V iti ake ka nui ake te maitai i roto i te tinana mō ngā mahi e nui ake ai te hiranga o te pakari i te rahinga nui o te putorino. Ko tēhea te mea hei whakamahi ka whakawhirinaki ki te pakari o te rauemi, ki te pakari rānei o te wāhanga mahi te mea e whakawhāiti ana - ehara i te mea ko tēhea te mea e matatau ake ana te tangi.
He aha ngā mea ka tupu ina ngaro te tautohe a te putorino
Ina kore te āhua o te putorino e ōrite ki te rauemi, ki te hohonu rānei o te kōhao, ka mutu te neke o te maramara i mua i te taenga ki te tihi o te putorino. Ka tākai ki roto i te awaawa, kaua e puta atu. Mai i reira, ka rite tonu te raupapatanga o te pakaru: ka whakanui ake ngā maramara tākai i te waku ki te pakitara o te putorino me te pakitara kōhao, ka tere ake te whakaputa wera o te waku i tana kaha ki te memeha, ā, ka tīmata te mata tapahi ki te tapahi anō i te rauemi kua tangohia kētia hei utu mō te rauemi hou. Ko ngā hua e kitea ana he poka taratara, he nui rawa rānei, he pikinga ohorere o te taipana, ā, — ki te nui te tākai — he wahi e tū ana, e motu ana i roto i te kōhao.
Koinei tonu te tauira e hokihoki tonu mai ana tēnei raupapa: ehara te kaihoko i te hoko i tētahi mata wiri, engari kei te hoko mai i tētahi kaha hanga kōhao pumau. He wāhi hapa te hoahoa o te putorino, he ngāwari ki te wareware nā te mea he rite te āhua o te putorino paerewa me te putorino parabolic i roto i te whakaahua. Ka kitea te rerekētanga ina tino hōhonu te kōhao, ina roa rawa rānei te hanga o te rauemi i ngā maramara kāore e taea e te awa whaiti te whakahaere.
Te Tikanga o Tēnei Ina Whakataurite i ngā Kaiwhakarato
Ehara tēnei i te mea e pā ana ki te putorino "pai ake". Engari ko te putorino i hangaia mō te mahi kei mua i a koe. Ina aromatawaihia he mata wiri ki tō tono tūturu, he mea tika kia pātaihia:
•He aha te hohonutanga o te kōhao e hiahiatia ana, ā, he nui te awa tuwhera o te putorino hei tango i ngā maramara i taua hohonutanga me te kore e patupatua pinepine?
•He rite te matotoru o te tukutuku mō te rauemi — he kaha o te matua, engari kāore e ārai i te hongere maramara?
•Mena kei te tuku te kaiwhakarato i tētahi putorino parabolic, ka honoa ki tētahi pūwāhi wehewehe hei whakahaere i te pana tāpiri, kāore rānei taua taipitopito i tāpirihia?
Koinei ngā pātai hei whakaatu ki a koe mēnā i hangaia te putorino mō te rauemi me te hohonu o te kōhao, i hangaia rānei mōna anake.
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.
