E rua ngā take e whakamahia ai ngā keri toka hau:
1. He mīhini keri kōhatu te wiri toka e whakamahi ana i te hurihuri me te pānga o te wiri maitai hei keri i ngā kōhao i roto i te toka, ā, e whakamahia ana hoki hei whakahoro i ngā whare kua whakarērea.
2. Ko te nuinga o te wā ka whakamahia hei keri tika i ngā rauemi kōhatu. Ka keri te keri kōhatu i ngā kōhao i roto i ngā hanganga kōhatu kia taea ai te whakauru i ngā mea pahū hei pupuhi i ngā kōhatu, hei whakaoti i te mahi keri kōhatu, i ētahi atu mahi kōhatu rānei.
Ko te taiao e tika ana mō te keri toka:
1. Ka taea te mahi noa i runga i te whenua papatahi, i ngā maunga teitei rānei, i ngā wāhi tino wera i runga ake i te -40 nekehanga Celsius, i ngā wāhi tino makariri rānei me te -40 nekehanga Celsius. Ka whakamahia ngā keri toka hau i roto i te keri maina, te keri, te hanga whare rānei, tae atu ki ngā rori sima, ngā rori uku rānei. He whānuitia te whakamahinga o ngā keri toka i roto i te hanga whare, te keri maina, te hanga ahi, te hanga rori, te tūhuratanga whenua, te hangarau tiaki whenua, te keri kōhatu, te hanga whare rānei, me ētahi atu mara.
rauemi mata keri toka
E rua ngā wāhanga o te mata keri toka, ko tētahi wāhanga he mea hanga ki te maitai 40Cr, 35CrMo rānei, ā, ko tētahi atu wāhanga he mea hanga ki te karāhe tungsten-cobalt.
He aha ngā momo keri kohatu kei reira?
E rua ngā momo keri toka e hangaia ana e te kamupene, e whakamahia ana mō te keri tika i te kohatu me te keri, me ētahi atu. Ka taea te wehewehe i te pūtake hiko ki ngā keri toka hau me ngā keri toka mura ā-roto.
He whakamārama taipitopito mō te aratau taraiwa:
Ka whakamahia e ngā keri toka hau te hau kōpeke hei akiaki i te piston kia patu whakamua i roto i te rango kia haere tonu ai ngā keri maitai ki te keri i te toka. He tino watea ki te whakahaere, he penapena wā, he mahi, he tere te keri, ā, he tino whai hua. Ko ngā keri toka hau te mea e whakamahia whānuitia ana i roto i te maina.
Me neke noa te kakau o te wiri toka mura ā-roto i te mea e hiahiatia ana, me te tāpiri penehīni kia mahi. Ka keria he kōhao ki roto i te toka, ā, ko te kōhao hohonu rawa atu ka taea te neke ake ki raro, ki raro rānei ki raro, ki raro rānei ki raro, ki raro rānei ki raro i te 45°. I ngā maunga teitei, i ngā whenua papatahi rānei. Ka taea te mahi i te wāhi tino wera o te 40°, i te wāhi makariri rānei o raro i te 40°. He whānui ngā mahi a tēnei mīhini.
te wiri toka waewae pana
Kua tāutahia te keri toka ki runga i te waewae hau hei whakahaere. Ka taea e te waewae hau te tautoko me te akiaki i te keri toka, ka whakaiti i te kaha o te mahi a te kaiwhakahaere kia taea ai e te tangata kotahi te whakaoti i te mahi a te tokorua, ā, ka nui ake te whai huatanga o te keri toka. Ko te hohonu o te keri 2-5m, ko te diameter 34-42mm te whakapae, te piko rānei o te poka pupuhi, he mea whakamahi whānuitia, ā, e pai ana ki ngā kamupene keri, pērā i a YT27, YT29, YT28, S250, me ētahi atu tauira pērā i ngā keri toka waewae-hau.
Ngā take e tika ana kia arohia mō ngā keri toka me te pēhea te keri i ngā kōhao:
1. Whakatauhia te tūnga o te kōhao me te ahunga werohanga, te koki o te whakatūnga o te waewae hau, me ētahi atu.
2. Me noho whakarara te paipa keri me te keri toka
3. Me pumau te wāhi mahi o te keri toka me te waewae hau (te taputapu pana rānei).
4. Ki te huri koe i te tūranga o te keri, te keri rānei, hurihia te koki o te waewae hau, ā, whakakapia te paipa keri, me tere ake te tere.
5. Kia tūpato ki te āhua porowhita, ki te āhua tika rānei o te kōhao pupuhi, tirohia mēnā kei te huri te tokotoko keri i waenganui o te kōhao pupuhi, ā, me mātakitaki tonu mēnā he noa te paura toka kua tukuna, me te mea kei te mahi noa te keri toka.
6. Whakarongo ki te tangi o te wiri toka, aromatawaihia mēnā he noa te pana o te rakau, te pēhanga hau, me te pūnaha whakahinuhinu, te tangi o ngā kōhao keri, ā, aromatawaihia mēnā kei te kitea he hapa hononga.
7. Te whakarerekētanga auau, me te wā tika hoki o te rahinga wai, te rahinga hau, me te koki o te waewae hau.
Ngā take mō te hurihanga rerekē o te wiri toka:
1. Mēnā kāore i te rawaka te hinu, me whakakī anō te keri toka
2. Mēnā kua pakaru te piston
3. He paru kei te takirere hau, kei ētahi atu wāhanga hurihuri rānei, mēnā e tika ana, whakatikahia, wetewetehia rānei, ka whakakapi i ngā wāhanga e tika ana i te wā tika?
