I roto i te ao whakataetae o te hanga tino tika, kua roa ngā mīhini CNC e kiia ana he tere me te tika. Ināianei, kua tae mai te QT500 Cast IronNgā Poraka Utauta Mazakkua whakaritea hei tautuhi anō i ngā paerewa mahi mō ngā mahi huri tere. I hangaia mō ngā mīhini huri CNC, ka whakakotahihia e ēnei poraka taputapu te pūtaiao rauemi me te auahatanga hangarau hei aro atu ki ngā wero nui e rua: te pakari o te taputapu me te roa o te wā e whakamahia ana.
Rino Maka QT500: Te Tuarā o te Pakari
Ko te whetu o tēnei auahatanga ko te rino maka QT500, he rino karāhe nodular e mōhiotia ana mō tōna hanganga iti, matotoru hoki. He rerekē ki ngā rauemi tuku iho, ko ngā mea e tukuna ana e QT500:
45% teitei ake te whakaiti i te wiri ki te whakaritea ki te maitai, e whakaiti ana i te hē o te harmony i ngā tapahi RPM teitei.
Kaha kume 500 MPa, e whakarite ana kia ātete ngā poraka taputapu i te whakarerekētanga i raro i ngā kaha radial tino kaha.
Te pumau o te wera tae atu ki te 600°C, he mea nui mō ngā mahi miihini maroke i roto i ngā rāngai rererangi me ngā rāngai motuka.
Mā te whiriwhiri i tēnei rauemi ka roa ake te ora o te pupuri taputapu mā te whakaiti i ngā whati moroiti i puta mai i te ahotea i roto i ngā rohe here.
Hoahoa Tika mō te Hototahi CNC
I hangaia kia pai ai te whakauru atu ki ngā pūnaha CNC, ā, ko ēnei poraka taputapu:
Te tika o te whakairinga pourewa i roto i te ±0.002mm, ka kore e roa te wā e kore ai e whakamahia.
Ngā hongere whakamatao motuhake ki a Mazak e tukutahi ana me ngā pūnaha pēhanga teitei hei whakaiti i te pāmahana whakauru mā te 25%.
He mokowā-T kua whakapakeketia me ngā paninga ārai-whakapouri hei ārai i te piri o ngā rauemi i te wā e whakamahia ana te titanium, te Inconel rānei.
