Te Mārama ki ngā Āhua me ngā Rahi o ngā Papahua mō te Mahi Pai

Momo 27 vs Momo 29: Rawa vs Ngā Tautohekoheko me te Roa o te Mata Takotoranga

Ko te hoahoa maromaro o ngā papa Type 27 e mahi pai ana ina heke kei waenganui i te 0 ki te 15 nekenga. E tuku ana i ngā wāhi takotoranga pai nā reira koia te mea tino pai mō te whakamāmau i ngā tapa, me te mahi whakamutunga. Engari ina titiro mātou ki te Type 29, ko tana hoahoa kōneke e muaki ana i te 35% atu ake o te rohe ki ngā raima. Arā pea, e āki ai i ngā nekenga piki ake mai i te 15 ki te 35 nekenga, ina hua tonu te tango i te nuinga o te matūrangi mai i ngā mata kurukuru, tauwahi rānei. Mō te mahi ki te hinu motuhake, ko ngā papa maromaro arataki e tangohia ana e te 1.2 ki te 1.8 pauna ia haora. Engari ka taea e ngā papa kōneke te eke ki te 2.5 pauna ia haora nā te mea e pakari ake ana te pā ki te mata i te wā e mahi ana. E kitea ana e te nuinga o ngā toihana tēnei rerekētanga he nui ake ina whai kiko ana ki ngā kaupapa nui kei te wā he take.

Te Whakauru i te Hāngai Papa ki te Kōnga Mahi (0–15° vs 15–35°)

Ko te āhua o te mahi e whakarāwekia ana te hikoenga o te wero i te wero. Ina mahi i waenganui i te 0 ki te 15 nga wā, ka pakaru ngā papa Type 27 i te totohu ki te mata, e awhina ai i te pupuri i ngā waehe māmā ki ngā waehe iti ake. Ki te nuku ki ngā āhuatanga mai i te 15 ki te 35 nga wā, āe, ka maru te āhua motuhake o ngā papa Type 29. Ko tana āhua rite ki te kapu kākāriki e āki ai i te kōpae kia kaua e tūpono ki ngā tapa, nō reira he pai rawa mō te mahi i ngā mea porowhita pērā i ngā takotoranga karaihe, ngā hononga pīpoi rānei e waru ana ngā papa torotika. Mō te katoa e mōhiotia ana te wero i ngā here o te mātā stainless steel, e mōhiotia ana tēnei whiri: whakarārangia te āhua ki te 25 nga wā ki ngā papa Type 29, ka kitea ka wehe te matapae pea 28 ōrau tere ake i ngā papa paparua noa. He mea tika anō te whakapono mō te tikanga nei e nui ana ngā tohunga i ēnei rā.

Te Kōwhiringa i te Tini e Tika ana: 4-inihi ki te 7-inihi, ngā Papatipu Iti mō te Roa ki te Kaha

Kāore e poto ana ngā porowhita nui (7-iniha) 40% i ngā tauira 4-iniha ina mahi ana ki ngā ripa hiriwa, engari me ngā kākahu ārai kaha ¥10A. Ka tuku ngā porowhita mini (2–3-iniha) i ngā paerewa tata o 0.8mm ki ngā taupiri karaihe, he pai rawa mō ngā mahi taipitopito kei hea te urupare he iti.

Tūhuratanga Koorero: Momo 27 mō ngā Mahi Tātahi ki Momo 29 mō ngā Mata Ahuroa

Ina mahi ana ki te hiko irons, ko te tikanga pai ko te whai i ngā tuanui karapoti tūtohu me ngā kōpae āhuarangi e 10 aniani pea te hiko. Ka pai ake tēnei tautuhi ki te mahi nui ake. Ki ngā wāhi iti rawa, ina heke iho rānei te takotoranga ki raro i te 10 neehu, ka pai ake ngā tuanui composite nā te mea ka maroke noa iho kia uru ai ki ngā wāhi pīroiro. Me whakamahi ngā kōpae paraihe teitei ina neke ake te tere o te taputapu i te 12 miriona RPM. Ka pupuri tēnei takotoranga i ngā totohu ōrite tae atu ki ngā mata kurupōtia e mōhiotia ana mō ngā raruraru. Hiahia ana koe ki te mata paraire penei i te mata arorua mō ngā karapoti karuwha? Ko ngā kōpae ceramic density tīmata te mahi, engari kaua e pakaru tino - pupuri i te pēhanga ki te 25 psi, te iti ake rānei. Ina nui ake te kaha, ka ruinatia te mata, kaua e hanga i te mata māmā e hiahia ana katoa.

Te Kōwhiringa i te Mātai Tino Whakapaipai mō ngā Rino Rerekē

Ceramic Alumina vs Zirconia Alumina vs Aluminum Oxide: Te Manawaroa Tataki me te Whakahaere Putea

Ko te kōwhiringa o te mea pakaru e whai pānga nui ana ki te mahi me te kounga o te hua. Ko te ceramic alumina ka tango i te papa 22% tere ake i te aluminum oxide mō te mātātoko kua whakapūmau (Abrasive Tech Journal 2023), me te whakaparahara wera pai ake hei whakararo i ngā herenga matallurgy. Ngā ūpoko matua:

Ko ngā karu pakari a zirconia alumina e pupuri ana i te kaha kitenga ki te wā, kei te ko ngā karu pakari o ceramic alumina e whakaatu ana i ngā pārtihana pakaru hōu—ēnei rāua e pai ana mō te whakamahi ahumahi uaua.

Te Whakawhiti i te Mātai Kōhatu ki te Āhua Uaua o te Parahi me te Awhiwhi Tūmatakura

Ko ngā parahi uaua pērā i te parahi momona (Brinell 150–200) e amioria ana i te aukati kōngahu o te ceramic alumina kia kaua ai te uauatanga o te mahi. Ko te awhiwhi tūmatakura teitei o te parakiore e mahi pai ana me te tapahi marino a aluminum oxide. Mō ngā parahi titani (UTS 900 MPa+), ko te zirconia alumina e tuku ana i te roa o te ora engari kāore he nui kōngahu.
