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 ko te kopara me te koroma vanadium he tauira o ēnei. 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 chuck.
