Raupapa: He aha i kore ai e angitu ngā mata wiri | Tuhinga 2
Ngā Kupumatua: Ngā mata keri kobalt M35, HSS M35, te kounga o te mata keri kobalt, te manatoko rauemi o te mata keri, M35 vs M2
Ina tohua e ngā kaihoko ngā mata keri kobalt M35, he whakatau tika tā rātou. Ko te M35 — he maitai tere-rahi me te 5% kobalt — he pai ake te pakeke whero i ngā taumata HSS paerewa. Ka mau tonu tōna mata tapahi i ngā pāmahana teitei ake, he mea nui tēnei ina keri ana i te maitai kore waikura, te rino maka, me ētahi atu rauemi uaua rānei.
Ehara i te mea ko te M35 te rauemi te raruraru. Ko te raruraru, kāore te tapanga "M35" i runga i tētahi hua e kī taurangi ana ko te maitai i roto he M35 tonu.
He aha te M35, ā, he aha te nui ake o tōna utu
He maitai tere-rahi te M35, he mea hanga ki te konumohe-konumohe. Mā te nui o te konumohe — tata ki te 5% — ka piki ake te kaha o te maitai ki te pupuri i te pakeketanga i raro i te wera. Ina tapahia e te mata keri te rauemi mārō, te rauemi whakakoi rānei, ka puta he pāmahana nui i te mata tapahi. Ka tīmata te ngawari o ngā momo HSS paerewa i aua pāmahana. Kāore te M35 e tere, kāore rānei i te tere rawa.
Koia te take he nui ake te utu mō te M35. Ko te utu mō ngā rauemi mata anake he 10–20% te nui ake i te M2, ā, he whānui ake te rerekētanga ki te whakataurite ki ngā momo HSS iti iho. Ina kite koe i te utu mō te M35 e tata ana ki te HSS paerewa, me ara ake he pātai.
Te Wāhi e Hē ai a "M35"
E whakaahua ana ngā whakatakotoranga rauemi i ngā mea e tika ana kia whakaurua ki roto i te maitai. Ko te mea kāore e kitea e ngā kaihoko — me te mea hoki e whakamahia ana e ētahi kaiwhakarato — ko te āhua ōrite o te mata keri kua oti ahakoa he M35 tūturu te maitai i roto, kāore rānei.
He torutoru ngā huarahi e puta ai tēnei i roto i te mahi.
Ko te tuatahi he whakakapinga māmā noa iho. Ko ngā awheawhe iti ake he iti ake te utu whakahaere, kāore hoki he pūnaha kounga, ka whakamahi pea i te HSS paerewa, i te iti iho rānei o te ihirangi cobalt, ka tapaina te hua ko M35, ka whakaritea he utu whakataetae. Kāore he huarahi e taea ai e te kaihoko te kī mā te tirotiro kanohi anake.
Kāore i te tino kitea te take tuarua: ahakoa he tika te taumata o te maitai, me whakataurite te maimoatanga wera ki te rauemi. Kāore e rite ngā tawhā maimoatanga wera pai o te M35 me te M2 — ka rerekē te urupare a te maitai ki te tukanga whakapakeke nā te nui ake o te konupora. Kāore te wheketere e whakahaere ana i te huringa maimoatanga wera kotahi ahakoa te taumata o te rauemi e tino mōhio ana ki ngā kaha o te M35. Ahakoa he maitai tūturu te maitai, he iti noa iho te putanga.
Kotahi tonu te putanga o ēnei raruraru e rua mai i te tirohanga a te kaihoko: he mata wiri cobalt e mahi ana pērā i te mata wiri paerewa.
Te Manatoko a ngā Kaihanga i ngā Rauemi
I tō mātou wheketere, ka manatokohia te maitai e tae mai ana mā te whakamahi i tētahi tātari whakarewa — he ine matawai e pānui ana i te hanganga tūturu o te rauemi. Koinei te tikanga pono rawa atu hei whakaū i te nui o te cobalt me te hanganga whānui o te koranu. Kāore e ranea te tirotiro ā-kanohi, te arowhai taumaha, me ngā whakapuakitanga a te kaiwhakarato anake.
He mea nui tēnei momo manatoko rauemi hou nā te mea he maha ngā taumata o te mekameka tuku mō te maitai taputapu, ā, kāore e ōrite te whakahaere i ia taahiraa. Ko te mōhio ki tāu e tukatuka ana — i mua i te huri hei hua oti — koinei anake te huarahi hei pupuri i te ōritetanga.
Ngā Mea Ka Taea e Ngā Kaihoko te Mahi
Kāore e tumanakohia ana kia whakahaerehia e ngā kaihoko ā rātou ake tirotiro ine ine. Engari he mahi whai hua hei whakaiti i te mōrearea o te whiwhi hua kāore e rite ki ngā whakaritenga.
Mahi tahi me ngā kaihanga kua roa e mahi ana i te mahi whakaputa, ā, kua whakatūria he hononga ki ngā rauemi me ngā tukanga pumau. He mea nui te tauine i konei — he nui ake ngā take a ngā wheketere he rite tonu te rahinga ki te pupuri i tā rātou mekameka tuku, ā, he nui ake ngā mea ka ngaro mēnā ka heke te kounga.
He huarahi tika ngā arotake wheketere ki te kite i te mahi a te kaiwhakarato. Mā te kaihanga kāore he mea e hunaia ana e whakaatu ki a koe te papa whakaputa, ngā taputapu, me te whakahaere i ngā rauemi e tae mai ana. Ka taea hoki e koe te pātai mēnā kei te tautoko te kaiwhakarato i ngā whakamātautau rauemi tuatoru. Kāore te kaihanga māia e whakahē ki te tirotiro motuhake a te ine ira i runga i tētahi tauira mai i tō ota.
Ehara te utu i te tohu tino tika, engari he tohu. Ko te utu tūturu mō te M35 tūturu he mea ārahi e te rauemi mata. Mena ka rite te utu mō te mata keri cobalt ki te HSS paerewa, kāore e pai te ōhanga.
Te Wāhi Whānui
He whakatakotoranga whai tikanga te M35 — ina koia tonu te mea e kīia ana. He take kei reira te nui o te cobalt, ā, he tika te tono a ngā kaihoko e hiahia ana ki te mahi pono i roto i ngā rauemi pakeke ake.
Engari ko te pono o tētahi whakatakotoranga ko te kaiwhakarato kei muri i a ia. Ko tētahi wāhanga o te pikitia ko te manatoko i te kounga o ngā rauemi. Ko tētahi atu wāhanga ko te pēhea o te tukatuka i taua rauemi — me te whakarite kia tika te whakahaere i taua mea.
Koinā ngā kōrero mō te toenga o tēnei raupapa.
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.
