Ngā Mīhini Whakapūmau Rakau: Te Tika, te Mana, me te Mahi

He mea hanga ngā mata wiri rakau ki ngā āhua motuhake hei wikitoria i ngā wero muka o te rakau. He rerekē ki ngā mata wiri whānui, he hoahoa motuhake ēnei taputapu:

• Ngā Momo Brad Point: He koi te koikoi o waenganui hei ārai i te kopikopiko, he koi hoki kei te taha e wero ana i te kiko o te rakau kia kore ai e haehaea ngā kōhao.
• Ngā Mata Wāhanga-Whā, Ngā Mata Wāhanga-Whā: Mā ngā tapa tapahi whā me ngā awa hohonu ka taea te pana tere i te maramara i te wā keri hohonu—he mea pai mō ngā raka tatau me ngā rakau matotoru.
• Ngā Matawai Ākeri: Ka tōia e ngā pailate he mata tīwiri te matawai mā roto i te rakau, ko ngā putorino porowhita ka tangohia ngā maramara i roto i ngā rīpene tonu—he tino pai mō te anga rakau.
• Ngā Mata Hāko: Ka tere te keri i ngā kōhao nui te whānui o ngā mata papatahi me ngā pūwāhi pokapū, ahakoa me nui te tautoko mō te pakaru o te taha putanga.Ripanga: Whakataurite i ngā Momo Matawai Poka Rakau

  Momo Moka	Te Hōhonutanga Mōrahi	Tere (RPM)	Te Kaha Matua
  Brad Point	75mm	1,500-3,000	Te tika o te taiaho, ngā pakitara maeneene rite ki te karāhe
  Pūtorino-Whā	430mm*	1,000-2,000	Te hōhonutanga hohonu, te tere ake o te tango maramara 30%

  Hāpara	150mm	1,000-2,500	Ngā kōhao tere nui (6-38mm)

  Ngā Huarahi Hou o te Hangarau: Ngā Rauemi me ngā Hangarau

  Ngā Auahatanga Whakarewa

  • Maitai Waro Teitei: Whakamahia i roto i ngā mata o te hāpara FANXI, kua whakapakeketia kia ātete ki te pakū. Ka whakaitihia e te paninga waikura pango te waku me te ārai i te waikura.
  • Hanganga Rima-Metara: Ka whakakotahi i ngā mata tapahi HSS me ngā tinana maitai koranu—ka whakanui ake i te pakari o ngā rakau rino-mārō o Ahitereiria.
  • Te Whakatō Carbide: Kei ngā mata o te ahumahi ngā taha carbide kua paraitia mō te keri i ngā papa whakarārangi me ngā papa hiato me te kore e pakaru.

  Ngā Mea Ngaro o te Āhuahanga

  • Ngā Awa Horoi-ā-Whaiaro: Ka tere ake te tango a ngā hoahoa pūtorino-whā i ngā maramara 40% te tere atu i ngā mata noa, ā, ka ārai i te herenga ki te rakau mākū.
  • Ngā Waewae Hex (6.35mm): Whakakorehia te paheke o te chuck i roto i ngā taraiwa pānga, ka taea ai te whakarerekē i ngā mata kotahi.
  • Ngā Pūwāhi Arotau: Ka whakamahia e ngā mata kōhao a IRWIN ngā pito whānui hei whakaiti i te pupuhi me ngā tinana parabolic mō te tapahi kaha.

  He aha i whiriwhiri ai ngā tohunga i ngā poro rakau motuhake

  1. Te Whai Huatanga Kore e Taea
     Ka tere ake te keri a ngā mata wha-putorino i roto i ngā rakau pakari mā te whakaiti i te waku me te pana tonu o te maramara. 9. Ka whāngai aunoa ngā mata auger mā roto i ngā here rerewē me te iti o te kaha o te kaiwhakahaere.
  2. Kounga Whakamutunga Tino Pai
     Ka hangaia e ngā pū o Brad point ngā kōhao kua oti te kōhao i mua, ka kore ai e haehaea te papa rakau me te MDF—he mea nui kia kitea ai ngā hononga.
  3. Te Mana Whakahōhonu Hoha
     Me te hōhonutanga taketake 130mm me ngā tokotoko toronga 300mm, ka uru ngā mata kōhao-whā ki ngā kurupae 4×4 i te kotahi haerenga.
  4. Ngā Mahi Whakawhiti-Rauemi
     Ka taea e ngā mata poro-carbide te pupuri i ngā mea hiato rakau-kirihou (WPC), PVC, tae atu ki ngā rau konumohe, me te kore e huri te āhua.
  5. Te Roa o te Utauta
     E rua ngā wā ka roa ake te mau o ngā mata o te auger bi-metal i te maitai waro i roto i ngā rakau whakakoi pērā i te tīki
• Ngā Painga o ngā Mata Wiri Rakau
• (Te Keri Tika)
• Ko ngā mata pēnei i ngā mata wiri brad-point he mea hanga hei whakarato i te keri tino tika. Mā te pūwāhi o waenganui o ēnei mata ka whakarite kia tīmata tika te kōhao ki te wāhi e tika ana, ka whakaiti i te tūponotanga o te hē o te tūnga. He mea nui tēnei i roto i ngā kaupapa mahi rakau e hiahiatia ana te whakatakotoranga tika o ngā kōhao, pērā i te hanga tāonga, i te hanga kāpata rānei. Hei tauira, i te wā e hanga ana i tētahi raupapa kōhao mō te tāuta i ngā reti tākai, mā te whakamahi i te mata wiri brad-point ka whakarite kia ōrite te tāutanga o ngā reti, kia tika hoki te mahi.
  （Te Whakaiti i te Pakaru o te Rakau）

Nā te hoahoa papatahi o ngā mata Forstner me tā rātou mahi tapahi maeneene ka hua ake he kōhao ma, he iti hoki te haehae o ngā muka rakau. He mea nui tēnei ina mahi ana me ngā rakau mārō, ina rānei he mea nui te āhua o te kōhao, pērā i ngā taonga whakapaipai, i ngā mahi rakau whakapaipai rānei.
  （Te Whakanuia o te Whai Hua）
  Hei tauira, he mea hanga ngā mata keri hāpara mō te hanga kōhao tere i roto i te rakau. Ka taea e ōna mata tapahi whānui te tango tere i te nui o te rakau, ka taea ai e koe te keri kōhao tere atu i ngā mata iti ake, tika ake. Nā tēnei ka pai mō ngā kaupapa e hiahiatia ana te tere, pērā i te keri i ngā kōhao maha mō ngā waea hiko i roto i te kaupapa hanga. He pai hoki ngā mata keri auger, me ōna putorino roa hei tango maramara pai, mō te keri tere i ngā kōhao hohonu i roto i te rakau.
  Ngā momo mahi maha)
  Nā te maha o ngā momo mata keri rakau e wātea ana, ka taea te whakamahi mō ngā momo mahi maha.
