Ngā Whakataki mō ngā Mata Wiri: He Aratohu mō te Tīmatanga ki ngā Mata Wiri Rakau!

whakataki

He mahi toi te mahi rakau e hiahia ana ki te tika me te mahi toi, ā, kei te ngākau o te mahi toi tētahi taputapu taketake – te mata wiri rakau. Ahakoa he kamura mātau koe, he tangata aroha rānei ki te mahi-ā-ringa, he mea nui te mōhio ki te whiriwhiri me te whakamahi i te mata wiri tika mō tētahi kaupapa mahi rakau angitu.

I roto i tēnei aratohu whānui, ka rukuhia e mātou ngā āhuatanga uaua o ngā mata wiri rakau, me te tūhura i ngā momo, ngā rahi, ngā rauemi, me ngā paninga e whai wāhi ana ki tōna whai huatanga.

Me tīmata tātou ki te tūhura i ngā taputapu taketake e hanga ana i te mahi rakau pai.

Te Whakaurunga o te Mata Wīra Rakau

Rauemi

He maha ngā rauemi rerekē e whakamahia ana mō ngā mata wiri, e whakamahia ana rānei i runga i ngā mata wiri, i runga i te tono e hiahiatia ana.

Tungsten Carbide：He tino pakeke te karawiti tungsten me ētahi atu karawiti, ā, ka taea te keri i ngā rauemi katoa, me te pupuri i te mata kia roa ake i ētahi atu wahi. He utu nui te rauemi, ā, he pakarukaru ake i ngā maitai; nō reira, ka whakamahia whānuitia mō ngā pito o te wahi keri, arā, ngā wahi iti o te rauemi pakeke e mau ana, e whakawirihia rānei ki te pito o te wahi keri i hangaia ki te konganuku iti ake te pakeke.

Heoi, kei te piki haere te rongonui o ngā mahi i roto i ngā toa mahi ki ngā mata poro karāhe totoka. He uaua ki te whakauru i ngā pito karāhe totoka i roto i ngā rahi tino iti; i roto i ētahi ahumahi, ko te mea nui ko te hanga papa ara iahiko tānga, e hiahia ana kia maha ngā kōhao me te diameter iti iho i te 1 mm, ka whakamahia ngā mata poro karāhe totoka.

PCD：Ko te taimana polycrystalline (PCD) tētahi o ngā rauemi taputapu tino pakari, nō reira he tino ātete ki te kakahu. He paparanga matūriki taimana tōna, he matotoru tata ki te 0.5 mm (0.020 inihi), he mea here hei papatipu kua whakakāhia ki te tautoko tungsten-carbide.

Ka hangaia ngā mata ma te whakamahi i tēnei rauemi mā te whakakoi i ngā wāhanga iti ki te pito o te taputapu hei hanga i ngā taha tapahi, mā te whakakoi rānei i te PCD ki roto i te uaua i roto i te "mata o te tungsten-carbide". Ka taea te whakakoi i te mata i muri mai ki te rakau carbide; kātahi ka taea te huri ki ngā āhuahanga uaua ka kore e pakaru te whakakoi i ngā "wāhanga" iti ake.

Ko ngā mata PCD e whakamahia whānuitia ana i roto i ngā ahumahi motuka, rererangi, me ētahi atu ahumahi hei keri i ngā koranu konumohe whakakoi, i ngā kirihou kua whakapakarihia ki te muka waro, me ētahi atu rauemi whakakoi, me ngā tono e tino nui ana te utu mō te wā whakamutu o te mīhini ki te whakakapi, ki te whakakoi rānei i ngā mata kua tawhito. Kāore e whakamahia te PCD ki ngā konganuku rino nā te nui rawa o te kakahu e puta mai ana i te tauhohenga i waenga i te waro i roto i te PCD me te rino i roto i te konganuku.

Rino

Ngā poro maitai waro-iti ngohengohehe iti te utu, engari kāore e mau pai te mata, ā, me whakakoi pinepine. Ka whakamahia anake mō te keri rakau; ahakoa te mahi ki ngā rakau mārō kaua ki ngā rakau ngohengohe ka taea te whakapoto i te roa o te ora.

Ngā wahi i hangaia mai imaitai waro-teiteihe roa ake te mau ingā poro maitai waro-itinā ngā āhuatanga i whakawhiwhia mai i te whakapakeketanga me te whakamahana i te rauemi. Mēnā ka wera rawa (hei tauira, nā te whakamahana waku i te wā e keri ana) ka ngaro tō rātou kaha, ka hua ake he mata tapahi ngohengohe. Ka taea te whakamahi i ēnei mata ki te rakau, ki te whakarewa rānei.

Ko te maitai tere-rahi (HSS) he momo maitai taputapu; he mārō ngā mata HSS, ā, he ātete ake ki te wera i te maitai waro-nui. Ka taea te whakamahi hei keri i te konganuku, i te rakau mārō, me te nuinga o ngā rauemi i ngā tere tapahi nui ake i ngā mata maitai waro-rahi, ā, kua whakakapia te nuinga o ngā maitai waro.

Ngā koranu maitai kobalthe momo rerekē o te maitai tere-rahi he nui ake te konupora kei roto. Ka mau tonu tō rātou pakeke i ngā pāmahana teitei ake, ā, ka whakamahia hei keri i te maitai kore waikura me ētahi atu rauemi mārō. Ko te ngoikoretanga matua o ngā maitai konupora he pakarukaru ake i te HSS paerewa.

Paninga

Waikura pango

He paninga pango utu iti te waikura pango. Ka ātete te paninga waikura pango ki te wera me te hinu, tae atu ki te ātete ki te waikura. Ka roa ake te ora o ngā mata maitai tere-rahi nā te paninga.

Nitride titanium

He mea whakarewa tino mārō te nitride titanium (TiN) ka taea te whakamahi hei paninga i tētahi mata maitai tere-rahi (he mata whiri te nuinga), ka roa ake te roa o te tapahi mā te toru, neke atu rānei ngā wā. Ahakoa kua whakakoihia, ka pai ake tonu te tapahi me te roa o te wā e pania ana e te mata o mua o te paninga.

Ngā Āhuatanga

koki pūwāhi

Ko te koki pūwāhi, te koki rānei i hangaia i te pito o te mata, ka whakatauhia e te rauemi e whakamahia ai te mata. Ko ngā rauemi pakeke e hiahia ana ki tētahi koki pūwāhi nui ake, ā, ko ngā rauemi ngawari e hiahia ana ki tētahi koki koi ake. Ko te koki pūwāhi tika mō te pakeke o te rauemi ka pā ki te haereere, te haruru, te āhua o te kōhao, me te tere o te kakahu.

roa

Ko te roa mahi o te mata e whakatau ana i te hohonu o te poka ka taea te keri, ā, e whakatau ana hoki i te pakari o te mata me te tika o te poka ka puta mai. Ahakoa ka taea e ngā mata roa ake te keri i ngā poka hohonu ake, he ngāwari ake, arā, tera pea he hē te wāhi o ngā poka ka keria e rātou, ka kotiti ke rānei i te tuaka e hiahiatia ana. Kei te wātea ngā mata wiri hurihuri i roto i ngā roa paerewa, e kiia ana ko te roa-tumu, ko te roa-mīhini-whiri rānei (poto), ko te roa-Jobber tino noa (waenga), me te roa-taper, ko te raupapa-roa rānei (roa).

He tika ngā kakau o te nuinga o ngā mata wiri mō te whakamahinga a te kaihoko. Mō te keri taumaha i roto i te ahumahi, ka whakamahia ētahi mata me ngā kakau whakarara. Ko ētahi atu momo kakau e whakamahia ana ko te āhua-ono, me ngā pūnaha tuku tere motuhake.

Ko te ōwehenga whānui-ki-te roa o te mata keri kei waenganui i te 1:1 me te 1:10. Tērā pea he nui ake ngā ōwehenga (hei tauira, ngā mata huri "roa-rererangi", ngā mata keri pū hinu pēhanga, me ētahi atu), engari ki te teitei ake te ōwehenga, ka nui ake te wero hangarau ki te whakaputa mahi pai.

Ngā momo mata wiri:

Mata kani. Ki te kore e whakamahia tonutia, me papatahi, me whakamahi rānei i te kōhao hei whakairi, ki te kore, kaua e taea te whakarārangi i ētahi atu taonga ki runga i ngā mata kani papatahi, ā, me whai whakaaro ki te makuku me te ārai-waikura.

Mata pōro Brad (Mata Wiri Tākai):

Ko te mata wiri pūwāhi (e mōhiotia ana ko te mata wiri ngutu me te pūwero, me te mata wiri dowel) he momo rerekē o te mata wiri hurihuri i arotauhia mō te keri i te rakau.

Whakamahia he mata wiri rakau papatahi, he mata wiri porowhita rānei, e tika ana mō ngā mahi e hiahia ana kia hunaia ngā pūtu, ngā nati rānei.

Ko ngā mata wiri Brad point e wātea ana i ngā diameter mai i te 3–16 mm (0.12–0.63 inihi).

Mata Wiri mā roto i ngā kōhao

Ko te kōhao puta noa i te mea mahi he kōhao e tika ana kia puta mā roto i te katoa o te mea mahi.

Whakamahia he mata wiri porowhita mō te tere o te weronga, he mea e tika ana mō ngā mahi keri whānui.

Momo totohu hononga

Ko te mata keri hononga he tauira o te hoahoa mata keri ritenga mō tētahi tono motuhake.
Kua hangaia he inihi motuhake e whakamahi ana i ngā pakitara o tētahi kōhao 35 mm (1.4 inihi) te whānui, kua keria ki roto i te papa matūriki, hei tautoko.

Momo Forstner

Ko ngā mata Forstner, i tapaina i muri i tō rātou kaihanga, he pū kōhao papatahi, tika tonu te raro i roto i te rakau, i roto i tetahi aronga e pā ana ki te kiko o te rakau. Ka taea e rātou te tapahi i te taha o te poraka rakau, ā, ka taea hoki te tapahi i ngā pū kōhao e taupatupatu ana; mō ēnei mahi ka whakamahia i roto i ngā mīhini wiri, i ngā mīhini mīhini huri rānei, kaua i roto i ngā wiri hiko ringaringa.

Ngā Tohutohu Iti mō te Whakamahi i ngā Mata Wiri Rakau

Te whakarite

Me whakarite kia ma te wāhi mahi, kia tangohia atu ngā mea ārai e whakararuraru ana i te keri.
Kōwhiria ngā taputapu haumaru e tika ana, tae atu ki ngā mōhiti haumaru me ngā taupoki taringa.

TereKōwhiria te tere tika i runga i te pakeke o te rakau me te momo mata.
Ko te tikanga, he pai ngā tere puhoi mō ngā rakau mārō, engari ka taea te whakamahi i ngā tere tere ake.

Whakamutunga

Mai i te mārama ki ngā āhuatanga rerekē o te whiriwhiri i te momo, te rahi, me te rauemi tika ki te whakatinana i ngā tikanga matatau pēnei i te waihanga i ngā kōhao matapo me ngā kōhao mā roto, ka whai wāhi katoa ngā āhuatanga ki te ngaiotanga o te mahi rakau.
