Te tapahi lasertono
Ko te nuinga o te wā ka whakamahia ngā taiaho CO2 rere tere mō te tapahi taiaho o ngā rauemi whakarewa, nā te mea he pai te kounga o te hihi. Ahakoa he tino teitei te whakaata o te nuinga o ngā whakarewa ki ngā hihi taiaho CO2, ka piki ake te whakaata o te mata whakarewa i te pāmahana rūma me te pikinga o te pāmahana me te nekehanga waikura. Kia pakaru te mata whakarewa, ka tata te whakaata o te whakarewa ki te 1. Mō te tapahi taiaho whakarewa, me nui ake te mana toharite, ā, ko ngā taiaho CO2 mana-teitei anake ka pāngia e tēnei āhuatanga.
1. Te tapahi taiaho o ngā rauemi maitai
1.1 Tapahi taiaho CO2 tonu Ko ngā tawhā tukanga matua o te tapahi taiaho CO2 tonu ko te mana taiaho, te momo me te pēhanga o te hau āwhina, te tere tapahi, te tūranga arotahi, te hohonu arotahi me te teitei o te pūwero.
(1) Te mana o te taiaho He nui te awe o te mana taiaho ki te matotoru o te tapahi, te tere tapahi me te whānui o te tapahi. Mēnā he pumau tonu ētahi atu tawhā, ka heke te tere tapahi i te pikinga o te matotoru o te pereti tapahi, ā, ka piki ake i te pikinga o te mana taiaho. Arā, ko te nui ake o te mana taiaho, ko te matotoru ake o te pereti ka taea te tapahi, ko te tere ake o te tere tapahi, ā, ko te whānui tapahi he paku nui ake.
(2) Momo me te pēhanga o te hau āwhina I te wā e tapahi ana i te maitai waro-iti, ka whakamahia te CO2 hei hau āwhina hei whakamahi i te wera o te tauhohenga tahunga rino-hāora hei whakatairanga i te tukanga tapahi. He tere te tapahi, ā, he pai te kounga o te tapahi, inā koa ka taea te tiki i te tapahi me te kore he para piri. I te wā e tapahi ana i te maitai kore waikura, ka whakamahia te CO2. He ngāwari te piri o te para ki te wāhanga o raro o te tapahi. He maha ngā wā ka whakamahia te hau whakaranu CO2 + N2, te rere hau paparua rānei. He pānga nui te pēhanga o te hau āwhina ki te pānga tapahi. Mā te whakanui tika i te pēhanga hau ka taea te whakanui ake i te tere tapahi me te kore he para piri nā te pikinga o te tere rere hau me te whakapainga o te kaha tango para. Heoi, ki te nui rawa te pēhanga, ka taratara te mata tapahi. Ko te pānga o te pēhanga hāora ki te taratara toharite o te mata tapahi e whakaaturia ana i te pikitia i raro nei.
Ka whakawhirinaki anō hoki te pēhanga o te tinana ki te matotoru o te pereti. Ina tapahia te maitai waro-iti ki te taiaho CO2 1kW, ka whakaaturia te whanaungatanga i waenga i te pēhanga hāora me te matotoru o te pereti i te pikitia i raro nei.
(3) Te tere tapahi He pānga nui te tere tapahi ki te kounga tapahi. I raro i ētahi āhuatanga o te mana taiaho, he uara matua o runga me o raro e rite ana mō te tere tapahi pai i te wā e tapahi ana i te maitai waro iti. Mena he teitei ake, he iti iho rānei te tere tapahi i te uara matua, ka piri te para. Ina puhoi te tere tapahi, ka roa te wā mahi o te wera tauhohenga waikura ki te mata tapahi, ka piki ake te whānui o te tapahi, ā, ka taratara te mata tapahi. I te piki haere o te tere tapahi, ka āta whaiti haere te tapahi kia rite te whānui o te tapahi o runga ki te diameter o te ira. I tēnei wā, he āhua poro te tapahi, he whānui te tihi, he whaiti hoki te raro. I te piki haere tonu o te tere tapahi, ka iti haere tonu te whānui o te tapahi o runga, engari ka whānui ake te wāhanga o raro o te tapahi, ā, ka huri hei āhua poro hurihuri.
(5) Te hohonutanga o te arotahi
He pānga tō te hohonu o te arotahi ki te kounga o te mata tapahi me te tere tapahi. Mēnā he nui te hohonu o te arotahi o te pereti maitai, me whakamahi he kurupae he hohonu te arotahi; mēnā he iti te hohonu o te arotahi o te pereti angiangi, me whakamahi he kurupae.
(6) Teitei o te pūwero
Ko te teitei o te pūwero e pā ana ki te tawhiti mai i te mata pito o te pūwero hau āwhina ki te mata o runga o te mea mahi. He nui te teitei o te pūwero, ā, he ngāwari te whakarerekē i te nekehanga o te hau āwhina e panaia ana, ka pā ki te kounga me te tere o te tapahi. Nō reira, i te wā e tapahi ana i te laser, ka whakaitihia te teitei o te pūwero, ko te tikanga 0.5~2.0mm.
① Ngā āhuatanga o te taiaho
a. Whakanuia te mana o te taiaho. He huarahi tika, he huarahi whai hua hoki te whakawhanake i ngā taiaho kaha ake hei whakanui ake i te matotoru o te tapahi.
b. Te tukatuka pā. He tino teitei te kaha o ngā reera pā, ā, ka taea te wero i ngā pereti maitai matotoru. Mā te whakamahi i te hangarau tapahi reera pā auau teitei, whānui pā whaiti, ka taea te tapahi i ngā pereti maitai matotoru me te kore e whakanui ake i te kaha o te reera, ā, he iti ake te rahi o te tapahi i te tapahi reera tonu.
c. Whakamahia ngā taiaho hou
②Pūnaha whatu
a. Pūnaha whatu urutau. Ko te rerekētanga mai i te tapahi laser tuku iho, kāore e hiahiatia kia whakatakotoria te arotahi ki raro i te mata tapahi. Ina piki, heke te tūranga arotahi i roto i te pūnaha whatu urutau i ētahi mirimita i te ahunga matotoru o te pereti maitai, ka rerekē te roa arotahi i roto i te pūnaha whatu urutau me te nekehanga o te tūranga arotahi. Ka rite ngā huringa piki, heke o te roa arotahi ki te nekehanga whanaunga i waenga i te laser me te mea mahi, ka huri te tūranga arotahi ki runga, ki raro i te hohonutanga o te mea mahi. Mā tēnei tukanga tapahi e rerekē ai te tūranga arotahi me ngā āhuatanga o waho ka taea te whakaputa tapahi kounga teitei. Ko te ngoikoretanga o tēnei tikanga he iti te hohonutanga o te tapahi, ko te tikanga kāore e neke atu i te 30mm.
b. Hangarau tapahi arotahi-rua. Ka whakamahia he karāhe motuhake hei arotahi i te hihi kia rua ngā wā ki ngā wāhanga rerekē. E whakaaturia ana i te Pikitia 4.58, ko D te diameter o te wāhanga pokapū o te karāhe, ā, ko te diameter o te wāhanga taha o te karāhe. He nui ake te radius o te piko i waenganui o te karāhe i te rohe e karapoti ana, ka hanga he arotahi takirua. I te wā e tapahia ana, kei te mata o runga o te mea mahi te arotahi o runga, ā, kei te taha o raro o te mea mahi te arotahi o raro. He maha ngā painga o tēnei hangarau tapahi taiaho arotahi-rua motuhake. Mō te tapahi i te maitai ngawari, kāore e taea anake te pupuri i te hihi taiaho kaha-teitei i runga i te mata o runga o te konganuku kia tutuki ai ngā tikanga e hiahiatia ana kia mura ai te rauemi, engari ka pupuri hoki i te hihi taiaho kaha-teitei tata ki te mata o raro o te konganuku kia tutuki ai ngā whakaritenga mō te mura. Ko te hiahia ki te whakaputa tapahi ma puta noa i te whānuitanga o ngā matotoru rauemi. Ka whakawhānui ake tēnei hangarau i te whānuitanga o ngā tawhā hei whiwhi tapahi kounga teitei. Hei tauira, mā te whakamahi i te CO2 3kW. Mā te whakamahi i te taiaho, ka taea anake te tae o te matotoru tapahi tikanga ki te 15 ~ 20mm, ko te matotoru tapahi mā te whakamahi i te hangarau tapahi arotahi rua ka taea te tae ki te 30 ~ 40mm.
③Pupuhi me te rere hau āwhina
Me hoahoa te pūwero kia pai ake ai ngā āhuatanga o te rere o te hau. Ka mimiti te whānui o te pakitara o roto o te pūwero hau-oro, kātahi ka whānui, ka taea ai te whakaputa i te rere o te hau-oro i te putanga. Ka tino teitei te pēhanga o te tuku hau, engari kāore e puta he ngaru ru. Ina whakamahia he pūwero hau-oro mō te tapahi taiaho, he pai hoki te kounga tapahi. Nā te mea he pumau te pēhanga tapahi o te pūwero hau-oro i runga i te mata o te mea mahi, he tino pai mō te tapahi taiaho o ngā pereti maitai matotoru.
