Me pēhea te whiriwhiri i tētahi mata mō tō kani porohita?

Ko te kani porowhita te hoa pai rawa atu mō ngā kaupapa DIY maha. Engari kāore he utu mō ēnei taputapu mēnā kāore he mata kounga teitei āu.

I te wā e whiriwhiri ana i tētahi mata kani porowhita, he mea nui kia whakaarohia ngā mea e whai ake nei:

ngā rauemi e whakaaro ana koe ki te tapahi(hei tauira, te rakau, ngā rauemi hiato, ngā konganuku kore-ferrous, te kirihou, me ētahi atu); mā tēnei ka whakatau te momo mata e hiahiatia ana e koe;

te hoahoa niho:kei runga i te rauemi e tapahia ana e koe me te momo tapahi e hiahiatia ana;
te waha korokoro: arā, te rahi o ngā āputa i waenganui i ngā niho; ka nui ake te āputa, ka tere ake te tapahi;

te pū:arā, te whānui o te kōhao i waenganui o te mata; ka inehia tēnei i roto i te mm, ā, ka taea te whakaiti mā te whakamahi i ngā rakau whakaiti;

te matotoru o te mata i roto i te mm;

te hohonutanga o te tapahi:e whakawhirinaki ana ki te whānui o te mata (e rerekē ana i runga i te momo kani);

te rauemi o te mata me te pito o ngā niho;e whakawhirinaki ana ki ngā rauemi e tapahia ana;

te maha o ngā niho:ka nui ake ngā niho, ka ma ake te tapahi; e tohuhia ana e te reta Z i runga i te mata;

te maha o ngā hurihanga ia meneti (RPM):e hono ana ki te diameter o te mata.

Kia mōhio kei roto i te mata kani ngā mokowā whakawhanui kia taea ai e te konganuku te whakawhanui i a ia e wera ana. Tērā pea he tohu me he whakarāpopototanga e hāngai ana ki te waitohu, ki te kaihanga rānei.

Te whānui o te poka me te mata

Ko ngā mata kani porowhita he kōpae whakarewa niho, he kōhao kei waenganui e kiia nei ko te pū. Ka whakamahia tēnei kōhao hei whakau i te mata ki te kani. Ko te tikanga, me ōrite te rahi o te pū ki te rahi o tō kani, engari ka taea e koe te whiriwhiri i tētahi mata he nui ake te pū mena ka whakamahia he mowhiti whakaiti, he rakau rānei hei whakau ki te kani. Mō ngā take haumaru e kitea ana, me iti ake hoki te diameter o te pū i te nati e whakau ana i te mata ki te kakau pū.

Kaua te whānui o te mata e neke ake i te rahi mōrahi e whakaaetia ana e tō kani porowhita; ka whakatakotoria ēnei mōhiohio ki roto i ngā whakaritenga hua. Ehara i te mea mōrearea te hoko i tētahi mata he paku iti ake engari ka whakaiti i te hohonu o te tapahi. Ki te kore koe e tino mōhio, tirohia ngā tohutohu a te kaihanga, tirohia rānei te rahi o te mata kei runga i tō kani i tēnei wā.

Te maha o ngā niho i runga i te mata kani porowhita

He maha ngā niho o te mata kani e mahi ana i te mahi tapahi. Ka whakatakotoria ngā niho ki te porowhita o te mata kani porowhita. Ka rerekē te maha o ngā niho i runga i ngā āhuatanga maha, tae atu ki te whakamahinga, nō reira me whakatau koe mēnā ka whakamahia te mata hei haehae, hei tapahi whakawhiti rānei. Koinei te wāhanga o te mata e mahi ana i ngā tapahi. Ko te wāhi i waenganui i ia niho e kiia ana ko te korokoro. Mā ngā korokoro nui ake ka tere ake te puta o te puehu. Nō reira, he pai te mata he nui ake ngā niho e wehea ana i waenganui mō ngā tapahi haehae (arā, te tapahi me te kākano).

Ki te rerekē, mā ngā niho iti ka pai ake te āhua o te tapahi, inā koa ka tapahia ngā mea whakawhiti (arā, te mahi i te taha o te anga). Ko te tikanga, mā ngā niho iti ka puhoi ake te tapahi.

He mea nui kia mōhiotia ko te rahi o te waha poka he mea nui ake i te maha o ngā niho. Ko te mata 130 mm me ngā niho 24 ka rite tonu ngā waha poka ki te mata 260 mm me ngā niho 48. Mena he ahua uaua katoa, kaua e manukanuka - he tohu ngā mata hei tohu i te momo mahi e taea ana e rātou te whakahaere ahakoa he mahi taratara, he mahi whakaoti, he maha rānei ngā mahi.

Tere Hurihanga

Me whai te tere hurihuri o te kani porowhita i ngā taunakitanga a te kaihanga mō te mata kani motuhake. Kua hangaia ngā mata kani katoa mō te whakamahinga haumaru i te maha mōrahi o ngā Huringa ia Miniti, arā, ko te RPM”, e tohu ana i te maha o ngā hurihanga i roto i te meneti. Ka whakaratohia e ngā kaihanga ēnei mōhiohio ki runga i te takai o te mata, he mea nui hoki hei whakamōhiotanga haumaru. I te hoko mata kani porowhita, he mea nui kia whakarite kia iti iho te RPM mōrahi o te kani e piri ai te mata i te RPM mōrahi kua whakahuatia i runga i te takai o te mata.

RPM mā te Kani

Ko te tere o ngā motuka hiko kāore i te whakamahi i ngā taputapu he 1,725 ​​RPM, 3,450 RPM rānei. He maha ngā taputapu hiko he taraiwa tika, arā, ka piri tika te mata ki te pou motuka. Mō ēnei taputapu taraiwa tika, pērā i ngā kani porowhita ringaringa (ehara i te mea he taraiwa noke), ngā kani tēpu me ngā kani ringa radial, koinei te RPM e mahi ana te mata. Heoi, kei reira ētahi kani porowhita ehara i te taraiwa tika, ā, he rerekē ngā tere e mahi ana. Ko ngā kani porowhita ringaringa he taraiwa noke te tere e rere ana i waenga i te 4,000 me te 5,000 RPM. Ka taea hoki e ngā kani tēpu whitiki te neke atu i te 4,000 RPM.

Tere mā te Rauemi

Ahakoa e whakatauria ana ngā kani me ngā mata e ō rātou RPM, ehara i te mea ko te tapahi rauemi. He rerekē anō te momo tapahi, arā, te ripping, te crosscutting rānei. Nā te mea ehara te RPM o te kani i te tohu pai mō tōna tere tapahi. Ki te tangohia e koe ngā kani e rua, ko tētahi he mata 7-1/4” te whānui, ko tētahi he mata 10” te whānui, ā, ka whakahaerehia i te tere ōrite, e ai ki te inenga i roto i te RPM, kāore e tapahia i te tere ōrite. Nā te mea ahakoa e neke ana te pokapū o ngā mata e rua i te tere ōrite, ko te taha o waho o te mata nui ake kei te neke tere atu i te taha o waho o te mata iti ake.
