Te Kōwhiringa o ngā Mata Tapahi mō ngā Kaitapa Whakarewa

I te whakamahi i tētahi taputapu tapahi whakarewa tika hei tapahi i ngā wahi mahi, me whiriwhiri ngā mata tapahi e ōrite ana ki ngā āhuatanga rauemi o te wahi mahi i runga i ōna rauemi rerekē, kia tutuki ai ngā hua tapahi whai hua. Kei raro nei, ka matapakihia e mātou te kōwhiringa o ngā mata tapahi mai i ngā tirohanga e toru:

1. Kōwhiringa i runga i ngā Āhuatanga Rauemi

1) Mō ngā rauemi whakarewa pēnei i te maitai, te rino, me ngā koranu, me whakamahi ngā mata tapahi e herea ana ki te kapia. Ko te matotoru i te nuinga o te wā kei waenga i te 1-2 mm, he mea e tika ana mō te tapahi pai i ngā rauemi whakarewa pēnei i te maitai whakapakeke. Ka taea hoki te whakamahi i te Rohe Pānga-Wera mō ngā āhuatanga tapahi tika pēnei i te tātaritanga whakarewa. Hei tāpiri, ka taea te whakaiti i te kino o te tapahi mā te whakarerekē i te tere whāngai.

2) Mō ngā rauemi pakarukaru kore-whakarewa pērā i te uku me te karāhe, me whakamahi ngā mata tapahi taimana. He pakari te kakano o ēnei mata, ā, he pai te kawe wera, ka taea ai te whakaiti i te tūponotanga o te kino wera.

3) I roto i ngā ahumahi haurua-ira, ara iahiko whakauru, me te PCB, he whānuitia te whakamahinga o ngā mata tapahi taimana tino-kikokore mō te whakahaere kounga me te tātari rahunga.

2. Te Kōwhiringa i runga i ngā Whakaritenga Mata Tapahi me ngā Whakaritenga Whai Hua

1) Mēnā kāore e hiahiatia he rerekētanga o te āhua o te mea mahi, ā, he tino ma te mata, whiriwhiria he mata tapahi angiangi (matotoru: 0.3-1.0 mm). Mā ēnei mata ka whakaiti i te paparanga pakaru tapahi, ka āwhina i ngā mahi huri i muri mai.

2) Mēnā e hiahiatia ana he tere tapahi me te whai hua teitei, whiriwhiria he mata tapahi matotoru (matotoru: 1.2-3.0 mm). He pakari ēnei mata, kāore e ngāwari ki te whati, ā, he pai mō te tapahi puranga.

3. Kōwhiringa i runga i te mārō o te mea mahi

Ko te pakeke o te mea mahi te mea e whakatau tika ana i te whiriwhiringa rauemi mō te mata tapahi. I taua wā, me whai whakaaro ki ngā whakaritenga kua whakahuatia ake nei mō ngā mata angiangi, matotoru rānei (i runga i te kounga/pai o te mata). Ko te teitei ake o te pakeke o te mea mahi, ko te ātete ki te kakahu me te pakari o te mata tapahi.

1) Ngā mea mahi tino pakeke (>HRC 50, hei tauira, te maitai whakapakeke, te karawiti sima, te maitai waro-teitei)

Ngā mata tapahi e tika ana: Ngā mata tapahi taimana, ngā mata tapahi cubic boron nitride (CBN) rānei

Matotoru e taunakitia ana: Ko te mea nui ko ngā mata matotoru (1.2-3.0 mm). He pakari, he ātete hoki ki te pakaru, ā, ka ārai i te pakaru i te wā e tapahi ana. Ka pakaru pea ngā mata tapahi noa i ngā mea mahi pakari, nō reira ka taea e ngā rauemi ātete ki te pakaru te whakarite i te pai o te tapahi; he pai te hanganga matotoru mō te tapahi taumaha.

2) Ngā mea mahi pakeke-waenga (HRC 30-50, hei tauira, te maitai waro noa, te rino maka, te maitai kore waikura)

Ngā mata tapahi e tika ana: Ngā mata tapahi taimana here-kapia, ngā mata tapahi alumina kounga teitei rānei

Matotoru e taunakitia ana: Kōwhiringa ngāwari — whiriwhiria ngā mata angiangi (0.3-1.0 mm) kia ma ai te mata, ngā mata matotoru rānei (1.2-3.0 mm) mō te tukatuka puranga. Nā te mea he pakupaku te rauemi, ka taea e ngā mata tapahi ātete-kakahu noa te whakatutuki i ngā hiahia tapahi, ā, ka taea te whakataurite i ngā mata angiangi/matotoru kia rite ki te kounga o te mata, ki ngā whakaritenga whai hua rānei.

3) Ngā mea mahi iti te mārō (

Ngā mata tapahi e tika ana: Ngā mata tapahi alumina noa, ngā mata tapahi taimana angiangi rānei

Matotoru e taunakitia ana: Ka aro nui ki ngā mata angiangi (0.3-0.8 mm); ka taea te whiriwhiri i ngā mata 1.0 mm mō ētahi rauemi. Ka ngāwari te piri me te whakarerekē i ngā taputapu ki ngā mea mahi iti te mārō; ka whakaitihia e ngā mata tapahi angiangi te horahanga pa, ka karo i te piri me te kino o ngā mea mahi. He rawaka ngā rauemi mata tapahi noa hei whakatutuki i ngā hiahia tapahi.

Ngā Tuhipoka Whakamutunga mō te Kōwhiringa Mata Tapahi:

Ka tino heke te pānga tapahi me te roa o te mahi a ngā mata tapahi mō te nuinga o te wā ina whakamahia ki runga i ngā rauemi motuhake.

Me whiriwhiri te mata tapahi kia rite ki te whirihoranga o te taputapu tapahi whakarewa e whakamahia ana. Hei tauira, kaua e whakamahia ngā mata tapahi matotoru ki ngā taputapu tapahi iti te mana, nā te mea ka ngāwari te utaina o te motuka, ka whati rānei te mata tapahi.
