Kei a matou te tikanga whakahaere kounga paerewa mairauemi mataki nga kaiarahi raina kua oti, ko ia tukanga e tino rite ana ki nga paearu o te ao. I roto i te PYG, ka mohio matou ki te raina whakaputa aunoa mai i te huri o te mata, te tapahi tika,horoi ultrasonic, whakakikorua, anti-waikura hinu ki te mōkihi. He mea nui ki a maatau te whakaoti rapanga mahi katoa mo nga kaihoko, me te whakapai tonu i te kounga hua me te ratonga.
Te Tirohanga Rawa
1.Tirohia te arataki raina me te mata poraka mena he maeneene me te papatahi, kia kore he waikura, kia kore he korikori, kia kore he rua.
2.Inehia te tika o te reriwe ma te mehua feeler me te torsion kia ≤0.15mm.
3.Whakamatauhia te pakeke o te reera aratohu ma te whakamatautau pakeke, me roto i te tohu HRC60 ± 2 tohu.
4.Ko te whakamahi i te ine micrometer hei whakamatautau i nga waahanga waahanga kaua e neke ake i te ± 0.05mm.
5.Inehia te rahi o te poraka ma te caliper me te hiahia ± 0.05mm.
Totika
1.Straight te aratohu raina ma te press hydraulic kia mau tonu te ≤0.15mm.
2.Whakatikahia te tohu toronga o te tereina ma te miihini whakatikatika taipana i roto i te ≤0.1mm.
Te whiu
1.Ko te hangarite poka kia kaua e neke ake i te 0.15mm，te manawanui o roto-poka diameter ± 0.05mm;
2.Ko te coaxiality o te poka i roto me te kohao countersunk kaua e neke ake i te 0.05mm, me te koki hurihuri orifice ka rite ki te kore he burrs.
Miro Papatahi
1) Whakanohoia te reera raina ki runga teepu ka pupurihia e te kopae, whakaparahatia ki te mallet rapa ka huri i te raro o te reera, te taratara o te mata ≤0.005mm.
2) Whakaritehia nga reeti ki runga i te papa miihini mira ka mutu te mira i te mata o te waahanga o nga reeti. Ko te koki o te rēreti e whakahaeretia ana ±0.03mm.
Rerewei & Poraka mira
Ka whakamahia he miihini miihini motuhake ki te huri i nga huarahi i nga taha e rua o te reera, kaore te whanui e neke ake i te 0.002mm, ko te paerewa teitei o te pokapū he +0.02mm, te teitei rite ≤0.006mm, te tohu o te tika iti iho i te 0.02mm, ko te 0.8 te utaina. N, te taratara o te mata ≤0.005mm.
Whakaoti Tapahi
Kuhua te kōtaha rēreti rārangi ki roto i te mīhini tapahi whakaoti, ka tapahia aunoatia te rahi tika o te rēreti, te paerewa o te rahi ≤0.15mm, te paerewa o te torsion ≤0.10mm.
Te tirotiro
Whakatikahia te reera raina i runga i te teepu mapere me te raka wiri, katahi ka tirohia te teitei o te huihuinga, te tika me te teitei rite ma te whakamahi i te poraka paerewa me te taputapu ine motuhake.
Te horoi
Whakaritehia te reera arahi ki roto i te riipene whakauru o te miihini horoi, kia mau tonu te mokowhiti ki te horoi, te whakaheke, te whakamaroke, te rehu hinu waikura.
Huihuinga me te kete
Kia mau ki te mata o te takirua kaiarahi raina kia kore he rakuraku, kaua he waikura, kaua he hinu i roto i nga rua, kia rite te hinu ki runga i te mata arataki raina, ka rere pai te rēreti me te kore e rewa me te riipene piri i runga i te kete kia kore e matara ka taka.
