Mā te hoko i tētahi huinga wiri ka penapena moni koe, ā, nā te mea kei roto tonu i tētahi pouaka, ka māmā ake te rokiroki me te tautuhi. Heoi, ko ngā rerekētanga iti o te āhua me te rauemi ka pā nui ki te utu me te mahi.
Kua kohia e mātou he aratohu māmā mō te whiriwhiri i tētahi huinga mata keri me ētahi whakaaro. Ko tā mātou whiringa pai rawa atu, ko te Huinga Mata Kerikeri Rino Kobalt 29-Wahanga a IRWIN, ka taea te whakahaere i te nuinga o ngā mahi keri - inā koa ngā konganuku mārō, ina kore e rahua ngā mata keri paerewa.
He māmā noa te mahi a te wiri, ā, ahakoa kāore anō kia rerekē te hoahoa taketake o te awaawa mō ngā rau tau, ka rerekē pea te āhua o te pito kia whai hua ai i roto i ngā rauemi rerekē.
Ko ngā momo tino noa ko ngā wiri hurihuri, ngā wiri taratara rānei, he kōwhiringa pai mō ngā mahi katoa. He rerekētanga iti ko te wiri pito-parāoa, he mea hanga mō te whakamahi ki te rakau, ā, he pito whaiti, koi hoki e ārai ana i te wiri kia kore e neke (e mōhiotia ana ko te hikoi). He rite tonu te tauira o ngā mata pereki ki ngā wiri hurihuri, engari he pito whānui, papatahi hei whakahaere i ngā kaha pānga nui e pā ana.
Kia neke atu i te inihi te whānui, kāore e taea te whakamahi i ngā wiri hurihuri. Ka taumaha rawa, ka nui rawa hoki te wiri. Ko te mahi e whai ake nei ko te wiri hāpara, he papatahi me ngā koikoi i ngā taha e rua, me te pito porotaka i waenganui. Ka whakamahia hoki ngā mata Forstner me ngā mata niho (ka puta he kōhao ma ake i ngā mata hāpara, engari he nui ake te utu), ko te mea nui rawa e kiia ana ko ngā kani kōhao. Engari ko te keri i tētahi kōhao i te tikanga noa, ka tapahia e ēnei he porowhita rauemi. Ka taea e te mea nui rawa te tapahi i ngā kōhao he maha inihi te whānui i roto i ngā poraka raima, i ngā poraka cinder rānei.
Ko te nuinga o ngā mata keri he mea hanga ki te maitai tere-rahi (HSS). He iti te utu, he ngāwari ki te hanga i ngā mata tapahi koi, ā, he tino pakari. E rua ngā huarahi e taea ai te whakapai ake: mā te whakarerekē i te hanganga o te maitai, mā te pania rānei ki ētahi atu rauemi. Ko ngā maitai kopara me te chrome vanadium he tauira o te mea tuatahi. He tino pakari, he ātete hoki ki te kakahu, engari he tino utu nui.
He iti ake te utu mō ngā paninga nā te mea he angiangi ngā paparanga i runga i te tinana HSS. He rongonui te tungsten carbide me te black oxide, me te titanium me te titanium nitride. He mata wiri pania-taimana mō te karāhe, te uku me ngā mata pereki nui.
Me noho he huinga taketake o te tekau mā rua pea ngā mata HSS hei paerewa mō ngā kete kāinga katoa. Mēnā ka pakaru tētahi, mēnā rānei he hiahia motuhake āu kei tua atu i tōna whānuitanga, ka taea e koe te hoko i tētahi atu hei whakakapi. Ko tētahi huinga iti o ngā mata pereki he mea nui anō hoki māu.
Haunga tēnā, he kōrero tawhito tēnei mō te whai i ngā taputapu tika mō te mahi. He mea whakarihariha te ngana ki te whakamahi i te korikori tinana hē hei mahi i te mahi, ā, ka taea te whakakino i tāu mahi. Ehara i te mea utu nui, nō reira he pai tonu te haumi ki te momo tika.
Ka taea e koe te hoko i tētahi huinga wiri iti te utu mō ētahi tāra, ā, i ētahi wā ka taea e koe te mahi, ahakoa he tere te memeha. Kāore mātou e tūtohu i ngā mata kōhatu kounga iti—he maha ngā wā, kāore e whai hua. He maha ngā huinga mata kōhatu kounga teitei e wātea ana mō te $15 ki te $35, tae atu ki ngā mata kōhatu SDS nui. He nui te utu o te cobalt, ā, ka taea e ngā huinga nui te eke ki te $100.
A. Mō te nuinga o te tangata, kāore pea. Ko te tikanga, ka whakatakotoria ki te 118 nekehanga, he mea pai mō te rakau, te nuinga o ngā rauemi hiato, me ngā konganuku ngohengohe pērā i te parahi, te konumohe rānei. Mena kei te keri koe i ngā rauemi tino mārō pērā i te rino maka, te maitai kore waikura rānei, me whai koki 135 nekehanga.
A. He ahua uaua te whakamahi ā-ringa, engari he maha ngā taputapu huri, ngā whakakoi wiri motuhake rānei e wātea ana. Me whakamahi he whakakoi taimana mō ngā wiri carbide me ngā wiri titanium nitride (TiN).
Ngā mea e pai ana ki a mātou: He whānuitanga o ngā rahi noa i roto i tētahi kāseti tango watea. He konukuraita ātete wera me te kakahu mō te roa o te wā mahi. Mā te koki 135-tohu ka taea te tapahi whakarewa pai. Mā te pūtu rapa e tiaki te anga.
Ngā mea e pai ana ki a mātou: He utu nui, mena ka mārama koe ki ngā herenga o ngā mata HSS. E whakarato ana i ngā wiri me ngā taraiwa mō ngā mahi maha huri noa i te kāinga, te karāti me te māra.
Ngā mea e pai ana ki a mātou: E rima noa iho ngā mata wiri, engari e 50 ngā rahi o ngā kōhao e wātea ana. He paninga titanium hei pupuri i te pakari. He hoahoa e tū ana i waenganui i a ia anō, he tino tika ake. Mā ngā papatahi o te kakau ka ārai i te paheke o te tīma.
