Te Aratohu Tino Pai mō ngā Mata Kani HSS: Te Tapahi Tika mō ngā Mahi Tino Uaua

Te Mārama ki te Hangarau HSS: Te Mahi Whakarewa e Hiranga ai te Rerekētanga

Ko ngā mata kani Rino Tere-Teitei (HSS) he whanaketanga hou i roto i te hangarau tapahi, e whakakotahi ana i ngā koranu rino me ngā tāpiri rautaki o te tungsten (14-18%), te molybdenum (5-8%), te chromium (3-4.5%), te vanadium (1-3%), me te cobalt (5-10%). Mā tēnei tunu whakarewa matatau ka taea e ngā mata te pupuri i te pakeke tino pai i ngā pāmahana neke atu i te 600°C – he painga nui i te wā e tere ai te pirau o ngā mata maitai waro noa. Kāore i rite ki ngā mata paerewa, ka mau tonu te pakeke Rockwell (HRC) o te 62-67 ahakoa i raro i te ahotea wera nui, e tika ana mō te mahi tapahi pumau i roto i ngā mahi roa 1.

Ka whakamahia e Shanghai Easydrill ngā tukanga maimoatanga wera korehau e whakahaeretia ana kia pai ai te hanganga tioata o ā rātou mata HSS M2, M35, me te M42. Mā tēnei huarahi tino tupato ka whakarite kia rite te tohatoha o te pakeke puta noa i te āhua o ngā niho, me te pupuri tonu i te pakari e tika ana i roto i te tinana o te mata – he taurite nui hei ārai i te pakaru kino o ngā niho i te wā e tapahia ana me te kawenga nui.

Ngā Painga Hangarau e Huri Ana i ngā Mahi Tapahi

1. Ātete Wera me te Mahi Whakamau Kāore i te ōrite
   E 3-5 ngā wā ka nui ake te pai o ngā mata HSS i ngā mata maitai waro tikanga i ngā wā tapahi pāmahana teitei. E whakaatu ana ngā rangahau, ina piki ake te tere tapahi mai i te 170 mm/min ki te 220 mm/min, ka 19% noa iho te teitei ake o te pakaru tuatahi o ngā mata HSS ki te 56% te tere o te pakaru i roto i ngā taputapu noa – e whakaatu ana i te pumau wera pai rawa atu 1. Ka puta tika tēnei ki te roa o ngā wā mahi me te whakaiti i te wā kore mahi.
2. Te Kounga Mata Tika
   E whakaatu ana ngā whakamātautau whakahaere he pai tonu ngā mata o ngā mata HSS (ngā uara Ra) nā te mea ka taea e rātou te pupuri i ngā mata tapahi koi. Ina piki ake ngā tere whāngai mai i te 425 mm/min ki te 550 mm/min, ka piki noa te taratara o ngā mata HSS mā te 10-14%, ki te whakataurite ki te 25%+ i roto i ngā momo kē atu 1. Nā tēnei ka tino hiahiatia rātou mō ngā tono whakaoti-tino nui i roto i te hanga rererangi me te hanga motuka.
3. Te Whānuitanga o ngā Rauemi
   Mā te taurite ahurei o te pakeke-kaha ka taea te tukatuka pai i ngā rauemi kanorau:
   • Ngā konganuku: Ngā koranu maitai (<45 HRC), te konumohe, te parahi, te rino ngāwari
   • Ngā Whakakotahitanga: CFRP, GFRP kāore he wehewehenga
   • Kirihou: Kiriaku, nairona, kirihou whakamahana kua whakapakaritia
   • Rakau: Ngā rakau mārō, ngā papa whakakikoruatia me ngā here kua whakauruhia

Ripanga Whakatairite Mahi:

Ngā Taupānga Ahumahi e Hiranga ai ngā Mata HSS

Te Mahi Whakarewa me te Mīhini
Ko ngā mata HSS a Shanghai Easydrill te nuinga o ngā pokapū ratonga whakarewa e tukatuka ana i te maitai hanganga, ngā paipa, me ngā kōtaha whakaputa. Ko ō rātou āhua niho rerekē (Triple Chip Grind, Alternate Top Bevel) ka ārai i te wiri harmonic i te wā e tapahi ana i ngā ngongo angiangi, ā, ko ngā paninga motuhake pēnei i te TiN ka whakanui ake i te hinu i roto i te tapahi maitai kore waikura.

Te Hanganga Waka
Ka whakamahia e ngā raina whakaputa ngā mata HSS kua whakarewahia ki te rēseri hei:

• Te miihini i ngā wāhanga miihini (te whakarewa rino nodular) 1
• Te whakakorenga o te taputapu tuku
• Te hanga i ngā wāhanga whakatārewatanga
  He mea nui ngā āhuatanga whakaiti wiri o ngā mata hei pupuri i ngā āheinga ā-ahu ±0.1mm i roto i ngā kani aunoa RPM-tiketike.

Rererangi me te Tiaki
Mō ngā koranu nikara nui (Inconel 718, Ti-6Al-4V), ka oma ngā mata M42 whai kopara-whakarei i ngā tawhā kua arotauhia:

• Tere Tapahi: 80-120 SFM
• Tere Whāngai: 0.8-1.2 mm/niho
• Whakamatao: 8% whakapūkara hangai
  Mā tēnei ka ārai i te whakapakeketanga o te mahi, ā, ka tutuki hoki ngā whakaotinga mata Ra<1.6μm e hiahiatia ana mō ngā wāhanga rere.

Te Kōwhiri i te Mata HSS Tino Pai: Ngā Tawhā Matua

Ngā Whakaaro mō te Āhua Niho

• Ngā Koki Matau: +10° ki te +20° mō ngā konganuku ngohengohe; -5° mō ngā rauemi pakarukaru
• Te Matotoru o te Niho: 60-80 TPI mō ngā ngongo angiangi; 8-14 TPI mō te rakau totoka
• Hoahoa o te awaawa: Ngā kōtaha piko hōhonu mō te tango maramara whai hua

Ngā Aratohu Arotau Mahi
I runga i te tātaritanga hoahoa whakamātautau o ngā tawhā miihini 1:

1. Whakatairangahia te whakahaere tere tapahi (Vc) mō te roa o te ora o te taputapu – 20% te tere rawa ka hua ake te 56% o te tere o te kakahu
2. Whakatikatikahia te tere whāngai (F) mō te whakaotinga mata – ka piki ake a Ra mā te 14% te mōrahi mā te pikinga 30%.
3. Tauritehia te hohonutanga o te tapahi (Dp) me te kawenga maramara – kaua e neke ake i te whānui o te mata × 1.2

Ngā Rautaki Ārai i te Rahunga

• Aroturuki i ngā wiri hāmoni e tohu ana i te pakaru o ngā niho
• Tirohia mēnā he pakaru iti i te 50% o te roa o te ora o te taputapu
• Whakamahia ngā rama strobe hei manatoko i te ōritetanga o te hanganga maramara
