Raupapa: He aha i kore ai e angitu ngā mata wiri | Tuhinga 1
Kupumatua: Ngā mata wiri HSS, ngā mata wiri kobalt M35, te kounga o te rauemi o te mata wiri, te hanga mata wiri, te maitai tere teitei
Ina pātai ngā kaihoko mō te kounga o te mata wiri, ko te pātai tuatahi e pā ana ki te rauemi.
"He HSS?" "He M35 cobalt?" "He aha te kounga o te maitai?"
He pātai tika ēnei. He mea nui te kounga o te maitai. Engari anei tētahi mea e kitea tonutia ana i roto i te umanga: ka rerekē rawa te mahi a ngā mata keri e rua i hangaia mai i te kounga kotahi o te maitai i te whakamahinga tūturu. Ka roa te mahi a tētahi. Ka tere te pakaru o tētahi.
Mena he ōrite te maitai, he aha i pēnei ai?
Nā te mea ko te kounga o te maitai te tīmatanga noa iho. Ko ngā mea e whai ake nei — te maimoatanga wera, te āhuahanga, te huri, te whakahaere kounga — e whakatau ana mēnā ka eke te maitai ki tōna pūmanawa. Ehara te mata keri i te mea he wahi maitai noa iho. He hua o te tukanga hanga katoa. Ā, ko ia taahiraa o taua tukanga ka taea te tiaki i te kounga o te rauemi mata, te whakangaro rānei.
Ngā Kōrero Tuturu a te Karaehe Rino ki a Koe
Ko te HSS (High Speed Steel) te rauemi paerewa mō te nuinga o ngā mata wiri whānui. Ka taea te whakamahi pai i te rakau, te kirihou, me te maitai ngawari i raro i ngā tikanga tapahi noa. Ko ngā momo konukōre-konumohe — M35 (5% konukōre) me te M42 (8% konukōre) — he mea hanga mō ngā rauemi pakeke ake, uaua ake hoki: te maitai kore waikura, te rino maka, ngā konukōre-teitei.
He rerekētanga tūturu, he rerekētanga whai tikanga ēnei. Ka whakanuia e te nui o te cobalt te pakeke whero o te maitai — tōna kaha ki te pupuri i te pakeke i ngā pāmahana teitei. Koia te take ka pai ake te mau o ngā mata keri cobalt i te wā e tapahi ana i ngā rauemi e whakaputa ana i te wera nui ake i te mata tapahi.
Engari ko te kounga maitai e whakaahua ana i te rauemi mata e uru mai ana ki te wheketere. Kāore he kōrero mō te mea ka tupu i muri mai.
Mai i te Rino ki te Mata Wiri: Te Wāhi e Hangaia ai, e Ngaro ai rānei te Kounga
Kia tae mai te rakau rino, ka maha ngā wāhanga ka haere i mua i te otinga o te mata keri. Ka tāpiri uara ia wāhanga — ka puta rānei he raruraru.
Me hanga te maitai kia tika te āhua o te mea para. Me tapahi, me huri rānei ngā putorino kia tika te āhua. Me huri te pito kia tika ngā koki. Ā, ko te mea nui, me whakamahana te mea para — he tukanga whakamahana me te tinei e whakahaeretia ana — kia eke ai te maitai ki tōna pakeke e hiahiatia ana.
I ia o ēnei mahi, ka hē pea ngā mea. Tērā pea ka hē te āhua o te āhua. Ka puta te ahotea i te hurihanga. Kāore e ōrite te maimoatanga wera. Ka huna pea ngā raruraru o raro i te whakaotinga o te mata.
Tērā pea ko te kounga o te maitai i utua e koe he rite tonu ki te mea i tohua. Engari ki te kore e pai te whakahaere i tētahi tukanga i raro iho, e kore rawa taua maitai e whakatutuki i tana kaha.
Koia te take e arotake ai ngā kaihoko mātau i ngā kaiwhakarato me ngā tukanga hanga - ehara i te mea ko ngā whakatakotoranga rauemi anake. Mā te tohu e tohu te tuanui. Mā te tukanga hanga e whakatau mēnā ka tata atu koe ki tēnā.
He aha te Hiranga o tēnei mō tō Mahi
Ka hokona e ngā kaihoko ngā mata wiri nā te mea e hiahia ana rātou ki te mahi pono, pumau hoki mō te hanga kōhao. Ko te mata wiri e pakaru wawe ana, e kore rānei e mahi ōrite puta noa i te puranga, ehara i te mea he utu taputapu anake — engari he wā kore mahi a te mīhini, he wāhanga kua whakakahoretia, he wā whakaputa kua pakaru.
He mea nui te maitai pai mō te mata wiri pai. Kāore e ranea.
Ina arotakehia e koe tētahi kaiwhakarato mata keri, ko te whakatakotoranga rauemi te pātai tuatahi. Ko te tukanga hanga, ko ngā mana whakahaere kounga, me te ōritetanga o ngā puranga ngā pātai e whai ake nei — ā, he mea nui anō hoki ēnei.
Mō tēnei raupapa
He raupapa hangarau a Why Drill Bits Fail nā tā mātou tīma hanga. E arotahi ana ia tuhinga ki tētahi āhuatanga o te mahi a te mata o te wiri - mai i ngā rauemi mata ki te takai. He māmā noa te whāinga: āwhina i ngā kaihoko ki te mārama ki tā rātou e hoko ana, me ngā pātai e tika ana kia pātaihia.
