Ko te whiriwhiri i te mata wiri hurihuri tika mō tō kaupapa me mārama koe ki ngā āhuatanga matua e toru: te rauemi, te paninga, me ngā āhuatanga āhuahanga. He mea nui ia o ēnei āhuatanga ki te mahi me te pakari o te mata wiri. Anei tētahi tirohanga whānui atu mō te whakatau whai whakaaro.
Rauemi
1. Rino Tere-Tiketike (HSS):
Neke atu i te rau tau te roa o te whakamahinga o te maitai tere-rahi (HSS) i roto i ngā taputapu tapahi, ā, he mea nui tēnei mō tōna whānuitanga o te whakamahinga me te utu tika. E mōhiotia ana ngā mata wiri HSS mō tōna maha o ngā mahi, ā, he pai te mahi me ngā wiri ā-ringa me ngā papa pumau pērā i ngā mīhini wiri. Ko tētahi painga matua o te HSS ko tōna kaha ki te whakakoi anō, e whakarei ake ana i te roa o te wā o ngā mata wiri, ā, he mea pai hoki mō ngā taputapu mīhini hurihuri. Hei tāpiri, he rerekē ngā taumata o te HSS, he rerekē ngā hanganga taketake o ia mea hei whakatutuki i ngā hiahia tapahi motuhake. Mā tēnei momo kounga maitai ka urutau te HSS, ka maha ngā mahi, ka nui hoki te hiranga o ngā mahi miihini.
2. Kopara HSS (HSSE, HSSCO rānei):
Ki te whakatauritea ki te HSS tuku iho, he tino pakari, he tino manawanui hoki te Cobalt HSS. Nā tēnei whakarei ake i ngā āhuatanga ka nui ake te ātete ki te pakū, ka roa ake, ka whai hua ake hoki ngā mata keri HSSE. Ehara i te mea ka nui ake te ātete ki te pakū, engari ka whakapai ake hoki i tōna roanga oranga. Pērā i te HSS paerewa, ka mau tonu te painga o ngā mata HSSE ki te taea te whakakoi anō, ka roa ake ai te wā e whakamahia ana. Nā te noho mai o te cobalt i roto i te HSSE, he tino pai ēnei mata mō ngā mahi keri uaua ake, he mea nui te roa me te ātete ki te pakū.
3. Kāpira:
He mea hanga te carbide i te nuinga o te wā ki te tungsten carbide me ngā momo here. He nui ake tōna pakeke, tōna ātete ki te wera, me tōna ātete ki te pakū i te HSS. Ahakoa he utu nui ake, he pai ake te roa o te ora me te tere o te miihini i ngā taputapu carbide. Me whai taputapu motuhake hei whakakoi anō.
Paninga
He rerekē ngā paninga mata wiri, ā, ka whiriwhiria i runga i te whakamahinga. Anei tētahi tirohanga poto mō ētahi paninga noa:
1. Kāore i pania (Kānapa):
Koinei te tae tino noa mō ngā mata wiri HSS. He pai mō ngā rauemi ngohengohe pēnei i te koranu konumohe me te maitai waro iti, ko ngā taputapu kāore i pania ngā mea tino utu nui.
2. Paninga Waikura Pango:
He pai ake te whakahinuhinu me te ātete ki te wera i ngā taputapu kāore i pania, ā, ka roa ake te ora mā te neke atu i te 50%.
3. Paninga Nitride Titanium (TiN):
He pai te mahi a ngā mata keri pania-tiatana i roto i ngā āhuatanga tono maha nā ō rātou āhuatanga mahi ahurei. Tuatahi, ka whakarei ake i te pakeke me te ātete ki te pao mā te paninga, ka taea ai e te mata te noho koi i te wā e keri ana i roto i ngā rauemi pakeke ake, ā, ka roa ake te ora ratonga. Ka whakaitihia e ēnei mata te waku me te kohikohi wera, ka whakanui ake i te pai o te tapahi me te tiaki i te mata mai i te wera nui. He pai ngā mata keri pania-tiatana mō te whakamahi i roto i te maha o ngā rauemi, pērā i te maitai kore waikura, te konumohe me te rakau, he mea pai mō ngā tono hangarau me ngā tono whare. Hei tāpiri, ka tere ake te uru o ēnei mata ki roto i ngā rauemi, ka whakarato i te mata tapahi ma. Ahakoa he nui ake te utu o ngā mata keri pania-tiatana i ngā mata keri noa, nā te pai o te mahi me te roa o te ora ka pai te hokinga mai o te haumi mō ngā tono e hiahia ana ki te ātete ki te pao me te tapahi tika.
4. Paninga Konumohe Titanium Nitride (AlTiN):
Tuatahi, he tino ātete ki te wera ngā paninga AlTiN, ā, ka taea e rātou te mahi pai i roto i te tapahi tere me te miihini i ngā koranu pāmahana teitei. Tuarua, ka tino whakapai ake tēnei paninga i te ātete ki te pakū me te roa o te ora o te taputapu, inā koa i te wā e miihini ana i ngā rauemi mārō pēnei i te maitai kore waikura, ngā koranu titanium me ngā koranu nikara. Hei tāpiri, ka whakaitihia e te paninga AlTiN te waku i waenga i te mata keri me te wāhanga mahi, ka whakapai ake i te pai o te miihini me te āwhina ki te whakatutuki i te mata tapahi maeneene. He pai hoki te ātete ki te waikura me te pumau matū, ka taea ai e ia te pupuri i te mahi i roto i ngā taiao mahi uaua. I te katoa, he pai ngā keri pania ki te AlTiN mō ngā tono miihini tere-teitei, tino tika, ā, he tino pai mō te whakahaere i ngā rauemi mārō e wero ana ki ngā keri tuku iho.
Ngā Āhuatanga Āhuahanga
1. Roa:
Ka pā te ōwehenga o te roa ki te whānui ki te pakari. Mā te whiriwhiri i tētahi mata wiri he nui te roa o te putorino hei tango i te maramara, ā, he iti noa te iri, ka taea te whakapai ake i te pakari me te roa o te taputapu. Ki te kore e ranea te roa o te putorino, ka kino pea te mata. He maha ngā paerewa roa hei whiriwhiri mā te mākete. Ko ētahi o ngā roa noa ko Jobber, stubby, DIN 340, DIN 338, me ētahi atu.
2. Koki Pūwāhi Wiri:
He mea noa te koki pūwāhi 118° mō ngā konganuku ngohengohe pērā i te maitai waro-iti me te konumohe. Kāore i te nuinga o te wā ka taea te whakapūmau i a ia anō, me whai kōhao ārahi. Mā te koki pūwāhi 135°, me tōna āhuatanga whakapūmau i a ia anō, ka kore e hiahiatia he kōhao whakapūmau motuhake, ka penapena nui i te wā.
Hei whakamutunga, ko te whiriwhiri i te mata wiri hurihuri tika ko te whakataurite i ngā whakaritenga o te rauemi e keria ana, te roa o te ora me te mahi e hiahiatia ana o te mata, me ngā whakaritenga motuhake o tō kaupapa. Mā te mārama ki ēnei āhuatanga ka taea e koe te whiriwhiri i te mata wiri tino whai hua me te whai hua mō ō hiahia.
