Te Mārama ki ngā Paerewa DIN 876: He Aratohu ki te Kōwhiri i te Reanga Tika mō ngā Pereti Mata Granite

Ma tēnei aratohu koe e ārahi i roto i ngā kaupapa matua o te DIN 876, hei āwhina i a koe ki te whakatere i ngā momo taumata me te whiriwhiri i te pereti mata karāhe tino tika mō ō hiahia ahumahi.

I mua i te ruku ki ngā paerewa hangarau, he mea nui kia mārama he aha te karāhe te rauemi pai mō ngā pereti mata tino tika. He rerekē ngā painga o ngā āhuatanga ā-tinana o te karāhe i ngā mea whakarewa, ā, he mea tino pai mō ngā taiao e tino hiahiatia ana te pumau o te wera me te tika mō te wā roa.

Tuatahi, he tino pakeke te karāneti. Ko te karāneti kounga teitei e whakamahia ana i roto i te ine ine he maha ngā wā e whakamanamana ana ki te pakeketanga Mohs o te 6 ki te 7, he pakeke ake i te maitai kua whakapakeketia. Mā tēnei ka tino ātete te mata ki te kakahu me te pakū, ka mau tonu tōna āhua ahakoa i roto i ngā taiao awheawhe pukumahi. Kāore i rite ki te maitai, he kore-aukume te karāneti, ā, kāore e kawe hiko, ka kore ai e pokanoa i roto i ngā inenga hiko tairongo, aukume rānei.

Ko te painga nui pea ko te pumau o te karāhe i te wera. He iti te tauwehenga o te whakawhānui wera me te kawe wera iti. Ko te tikanga o tēnei he iti noa te pānga o ngā piki me ngā heke o te pāmahana taiao ki ngā rahi o te pereti, ā, ka memeha haere, ka taurite hoki te wera ā-rohe (pērā i ngā ringaringa o te kaimahi, i tētahi wāhanga mahana rānei kua whakatakotoria ki runga i te tēpu), ka ārai i te whakapōturi. Hei tāpiri, he ātete waikura te karāhe, ā, he tino ātete ki ngā waikawa, e whakarite ana i te roa o te ora me te iti o te tiaki. Hei tāpiri atu ki tēnā, he ōrite te hanganga o te karāhe kounga teitei, ā, kāore he taumahatanga o roto, ko te tikanga ka ātete ki te piko me te takahuri i roto i te wā.

Ko te DIN 876 te paerewa ahumahi Tiamana e tohu ana i ngā whakaritenga mō ngā pereti mata karāhe. E mōhiotia whānuitia ana puta noa i te ao hei paearu mō te kounga i roto i te ine. E tohutohu ana te paerewa i ngā mea katoa mai i te momo kōhatu e whakamahia ana ki ngā rohe papatahi e whakaaetia ana.

E whakarōpūtia ana e te paerewa ngā pereti mata karāhe kia whā ngā taumata tika. Ko te whiriwhiri i te taumata tika he mahi taurite i waenga i te taumata tika e hiahiatia ana e koe me te tahua kei a koe. I te nuinga o te wā, ko te teitei ake o te taumata tika, ko te teitei ake o te utu nā te nui o te mahi e hiahiatia ana mō ngā tukanga whiu me te waru.

Tau 00: Te Paerewa Taiwhanga
Ko te tohu 00 te tihi o te papatahi me te tika. Ko ngā pereti mata e tutuki ana i tēnei paerewa he mea hanga me ngā taunga tino pakari, ā, he mea hanga mō te whakamahi i roto i ngā taiao whakahaeretia, pērā i ngā taiwhanga tirotiro me ngā rūma whakatikatika. Mena kei roto i tāu mahi te whakamana i ētahi atu taputapu ine, te mahi rānei i ngā inenga tino tika ina kore e whakaaetia ahakoa he iti noa te hapa, ko te tohu 00 te whiringa e hiahiatia ana e koe. Kāore i te kitea ēnei pereti i runga i te papa wheketere nā te mōrearea o te kino me te kore pumau o te taiao.

Tau 0: Te Paerewa o te Awheawhe Tika
Ko te Taumata 0 te paerewa mō ngā rūma taputapu tino tika me ngā wāhi tirotiro i roto i tētahi whare whakaputa. Ahakoa he iti ake te pakari i te Taumata 00, he tino papatahi tonu. He tino pai tēnei taumata mō te tohu i ngā wāhanga tino tika, te tirotiro i ngā wāhanga tino manawanui, me te whakatū i ngā taputapu miihini tairongo. Ka hono i te āputa i waenga i te tino pai o te taiwhanga me ngā tono pakari o te raina whakaputa.

Tau 1: Te Hōiho Mahi Whakaputa
Mō ngā mahi whānui o te awheawhe me ngā raina whakaputa, ko te Reanga 1 te mea tino rongonui. He mata tino tika, he pakari hoki mō te whakamahi i ia rā i roto i te taiao whakaputa. He pai ngā pereti Reanga 1 mō te whakatū mīhini, te tirotiro i ngā wāhanga i te wā whakaputa, me te mahi tahora whānui. He pai te taurite o te mahi me te whai huatanga o te utu, ā, he mea nui ēnei i roto i ngā awheawhe mīhini.

Tau 2: Te Ratonga Mahi Taumaha
He whānui ake ngā āheinga papatahi o ngā pereti Taumata 2, ā, he mea hanga mō ngā mahi taumaha kāore e tino tika te mahi. He maha ngā wā ka whakamahia ēnei mō ngā mahi whakatakotoranga taratara, ngā taputapu whakarewa, ngā taiao rānei ka pāngia pea te pereti e ngā pānga taumaha, e te whakahaere taratara rānei. Ahakoa kāore i a rātou te matatau o ngā taumata teitei ake, ka whakaratohia tonutia he mata tohutoro pono, papatahi hoki, he pai ake i ngā papa mahi kāore i te whakahaeretia.

Ko te whiriwhiri i te momo DIN 876 tika ko te pātai i ngā pātai tika mō tō tukanga mahi. Me whai whakaaro koe ki te taiao e noho ai te pereti me ngā mahi motuhake ka mahia e ia.

Mena kei te whakapaipai koe i tētahi taiwhanga whakahaere kounga e whakahaeretia ana te pāmahana, ā, ka oti ngā whakaaetanga whakamutunga mō ngā wāhanga rererangi, hauora rānei, kāore e taea te whiriwhiri i tētahi pereti Tau 00, Tau 0 rānei. Ka tika te utu nā te whakapumautanga o te tika tuturu.

Mō te papa mīhini pukumahi e hiahia ana ngā kaimahi mīhini ki te whakatū i ngā mira CNC, i ngā mīhini huri rānei, ko te pereti Tau 1 te mea pai rawa atu. He tika te pereti hei whakarite kia tika te mīhini o ngā wāhanga, engari he pakari hoki hei tu atu i ngā wiri me ngā mahi o te papa whakaputa.

Mena ko ngā mea e hiahiatia ana e koe ko te hanga taumaha anake, ko ngā tēpu whakarewa, ko te huihuinga taratara rānei e inehia ai ngā taunga ki ngā mirimita kaua ki ngā maikorona, ka pai te mahi a te pereti Wāhanga 2 ki a koe, engari kāore e nui rawa te tahua.

Ko te mārama ki ngā paerewa DIN 876 te taahiraa tuatahi ki te whakarite kia hangaia ō tukanga hanga me te tirotiro i runga i te turanga pakari. Ka tukuna e ngā pereti mata karāhe te pumau, te pakeke, me te roa e kore e taea te whakataurite, engari ka tino kitea te uara ina taurite te tohu tika ki tō tono motuhake.

Ahakoa e hiahia ana koe ki te kounga taiwhanga tino pai o te DIN 876 Grade 00, ki te pono pakari rānei o te Grade 1 mō tō raina whakaputa, mā te whiriwhiri i te taputapu tika ka taea te whakawhirinaki ki ō inenga, ka whai hua ō tukanga, ā, ka tutuki ō hua whakamutunga i ngā paerewa kounga teitei. Mā te haumi ki te kounga tika o te pereti mata karāhe, kei te haumi koe ki te tika me te ingoa pai o tō mahi katoa.
