whakaahuatanga hua
(1) PCD i roto i ngā tono motuka me te rererangi
Ko ngā taputapu PCD i roto i te ao motuka e whakamahia ana mō te tukatuka i te taha o te piston miihini, te kōhao pine, te poraka rango, te pouaka miihini me ērā atu mea. Nā te nui o te ihirangi silicon o ēnei wāhanga (neke atu i te 10%), ko te roa o te ora o te taputapu e hiahiatia ana, me te roa o te mau o te taputapu PCD he 1-50 ngā wā i te taputapu carbide, ka taea te whakarite i te pumau o te rahi o ngā wāhanga, ā, ka taea te whakapai ake i te tere tapahi, te pai o te miihini me te kounga o te mata o te mea mahi.
I roto i te mara rererangi, mā te whakamahi i ngā taputapu PCD e tukatuka ana i te pane rango konumohe (AlSi2), he tere tapahi teitei ake, ā, he 20 ngā wā ka pai ake te roa o te ora o te taputapu i te carbide sima, ā, ka tino pai ake te kounga o te mata o te mea mahi.
(2) PCD i roto i ngā mahi ahumahi tukatuka rakau
He mea nui anō hoki te tukatuka rakau i roto i ngā mahi taputapu PCD. Nā te tere o te whanaketanga o ngā panera hangai (papa muka matotoru reo, papa matūriki me ngā papa raima, me ētahi atu), ka tere ake te hiahia mō ngā taputapu tapahi tino mārō, ā, ka āta whakakapia ngā taputapu mahi rakau tuku iho e ngā taputapu PCD i te mākete.
He tino whakakoi te paparanga Al2O3 o waho o te papa laminate ki te taputapu carbide, ā, mā te whakamahi i ngā taputapu PCD ka taea te whakaoti i tēnei raruraru. Nō reira, ko te PCD i roto i te mākete matua o te umanga mahi rakau ko te papa hiato whakakaha me te tukatuka papa muka pakeke.
(3) PCD i roto i ngā tono ahumahi tukatuka hiko
Kei te piki haere te tono a te umanga hikohiko i roto i te hanga papa hikohiko, ka whai pūwero te taputapu whānui e whakamahia ana, ka pā ki te tāutanga me te tūnga o ngā wāhanga hiko, ā, kāore e ataahua te papa hikohiko katoa; he poto te ora o ngā taputapu tapahi carbide i roto i te tukatuka, he puhoi te tere tukatuka, he iti te pai o te mahi, he iti te tika o te miihini. Ko te whakamahinga o ngā taputapu PCD, he nui te pai o te tukatuka, he iti ngā utu tukatuka, ā, he whānui ake te whakamahinga.
(4) PCD i roto i ngā mahi tapahi me te tukatuka karāhe
Ko te wira tapahi i hangaia ki te PCD e whakamahia nuitia ana mō te tapahi mata LCD kounga teitei, tino tika hoki o ngā hua hiko, ā, i te wā kotahi ka taea te tapahi karāhe mō te hanga me te motuka. Ko te mandrel me te wira tapahi he mea hanga ki te rauemi PCD, he pai ngā painga o te tino tika o te tukatuka, te ātete ki te kakahu, te ōritetanga pai, me te roa o te ora mahi i te wā kotahi, he mea pai hei whakakapi mō ngā maripi karāhe noa me ngā wira tapahi karāhe carbide.
(5) PCD i roto i ngā tono ahumahi rauemi hiato
Mā te whakamahi i ngā taputapu PCD hei tukatuka i ngā hiato kua whakapakarihia ki te muka karāhe, ko te roa o te ora o te taputapu he 60 ngā wā o te roa o te ora o ngā taputapu carbide sima, ko te utu tukatuka wahi kotahi he 1/20 o ngā taputapu carbide sima, ā, he teitei ake te tika o te tukatuka i te carbide sima.
PCD
Ngā taputapu tapahi PCD kore
- Ka taea te whakarite i ngā papa tapahi PCD kia tutuki ai ngā hiahia motuhake a ō mātou kiritaki.Ko ngā taputapu tapahi PCD e whakamahia whānuitia ana mō te tapahi me te miihini i ngā konganuku kore-ferrous me ngā koranu pērā i ngā koranu SI/Al, te konumohe, te parahi me ngā koranu rite.Ka whakamahia hoki ēnei hei mīhini i ngā rauemi kore-whakarewa pērā i te rakau, te karāpeti, te uku, te kirihou, te rapa me ētahi atu, ina hiahiatia he ātete nui ki te pakū me te roa o te ora.
Ngā taputapu tapahi PCD kore
He pai mō ngā mata kani taimana, te keri me te keri hanga, ngā tapahi taimana mō te kuti taha, ngā whakaurunga PCD mō te huri me te mira, ngā mata keri taimana mō te keri kōhao i ngā rauemi hiato me ngā papa ara iahiko, me ētahi atu.
Ngā āhuatanga mahi o te PCD
(1) Te pakeketanga teitei me te ātete ki te kakahu
He tino pakari te PCD, he kaha pēhi teitei, he pai te kawe wera me te ātete kakahu, ā, ka taea te tapahi tere-teitei kia whiwhi ai i te tika o te miihini me te pai o te miihini. Ko ēnei āhuatanga o ngā taputapu PCD e whakatauhia ana e te āhua karaihe taimana, he kaha te kaha here me te ahunga o te hanganga, kia tino pakari ai te taimana.
(2) Te tika o te miihini
He iti te tauwehenga whānui wera o ngā taputapu PCD, ā, he teitei hoki te modulus o te ngāwari, nō reira, kāore e ngāwari te whakapēhanga i ngā taputapu i te wā tapahi, ā, i te wa ano, ka taea te whakaiti i te kaha tapahi me te pāmahana tapahi hei whakapai ake i te roa o te taputapu me te tere tapahi, kia pai ai te mata miihini.
(3) Te kawe wera teitei
He tino teitei te kawe wera o te PCD, he pai ake i te hiriwa, te parahi, ā, he teitei ake i te carbide sima whānui, nō reira he ngāwari te whakamarara i te wera i te tukanga tapahi, ā, he iti iho te pāmahana tapahi.
He mea nui anō hoki te tukatuka rakau i roto i ngā mahi taputapu PCD. Nā te tere o te whanaketanga o ngā panera hangai (papa muka matotoru reo, papa matūriki me ngā papa raima, me ētahi atu), ka tere ake te hiahia mō ngā taputapu tapahi tino mārō, ā, ka āta whakakapia ngā taputapu mahi rakau tuku iho e ngā taputapu PCD i te mākete.
Kei te piki haere te tono a te umanga hikohiko i roto i te hanga papa hikohiko, ka whai pūwero te taputapu whānui e whakamahia ana, ka pā ki te tāutanga me te tūnga o ngā wāhanga hiko, ā, kāore e ataahua te papa hikohiko katoa; he poto te ora o ngā taputapu tapahi carbide i roto i te tukatuka, he puhoi te tere tukatuka, he iti te pai o te mahi, he iti te tika o te miihini. Ko te whakamahinga o ngā taputapu PCD, he nui te pai o te tukatuka, he iti ngā utu tukatuka, ā, he whānui ake te whakamahinga.
Ko te wira tapahi i hangaia ki te PCD e whakamahia nuitia ana mō te tapahi mata LCD kounga teitei, tino tika hoki o ngā hua hiko, ā, i te wā kotahi ka taea te tapahi karāhe mō te hanga me te motuka. Ko te mandrel me te wira tapahi he mea hanga ki te rauemi PCD, he pai ngā painga o te tino tika o te tukatuka, te ātete ki te kakahu, te ōritetanga pai, me te roa o te ora mahi i te wā kotahi, he mea pai hei whakakapi mō ngā maripi karāhe noa me ngā wira tapahi karāhe carbide.
Mā te whakamahi i ngā taputapu PCD hei tukatuka i ngā hiato kua whakapakarihia ki te muka karāhe, ko te roa o te ora o te taputapu he 60 ngā wā o te roa o te ora o ngā taputapu carbide sima, ko te utu tukatuka wahi kotahi he 1/20 o ngā taputapu carbide sima, ā, he teitei ake te tika o te tukatuka i te carbide sima.
