Ko te huri he tikanga whakaoti e whakamahia whānuitia ana mō te hiri i te mata o ngā takirere i roto i te tukanga hanga. Mā te huri ka taea e te mata hiri takirere te whiwhi i te tika teitei o ngā āhuatanga, te taratara o te āhua ā-ira me te taratara o te mata, engari kāore e taea te whakapai ake i te tika o te tūranga i waenga i ngā mata o te mata hiri. Ko te tika o ngā āhuatanga o te mata hiri takirere whenua he 0.001~0.003mm te tikanga; ko te tika o te āhua ā-ira (pēnei i te kore taurite) he 0.001mm; ko te taratara o te mata he 0.1~0.008.
Ko te kaupapa matua o te hiri i te huri mata e rima ngā āhuatanga: te tukanga huri, te nekehanga huri, te tere huri, te pēhanga huri me te tahua huri.
1. Te tukanga huri
He pai te hononga o te taputapu huri me te mata o te mowhiti hiri, ā, ka mahi te taputapu huri i ngā nekehanga huri uaua i te mata hononga. Ka whakatakotoria ngā mea whakakoi i waenganui i te taputapu whakakoi me te mata o te mowhiti hiri. Ina neke te taputapu whakakoi me te mata o te mowhiti hiri tetahi ki tetahi, ka paheke, ka hurihuri rānei tetahi wāhanga o ngā pata whakakoi i roto i te mea whakakoi i waenganui i te taputapu whakakoi me te mata o te mowhiti hiri. paparanga whakarewa. Ka hurihia ngā tihi i runga i te mata o te mowhiti hiri i te tuatahi, kātahi ka tutuki mārire te āhua e hiahiatia ana.
Ehara i te mea he tukanga ā-ringa noa iho te huri i ngā mea whakakoi ki ngā konganuku, engari he mahi matū anō hoki. Ka taea e te hinu i roto i te mea whakakoi te hanga i tētahi kiriata waikura ki runga i te mata hei tukatuka, ā, ka tere ake te tukanga huri.
2 . nekehanga huri
Ina neke te taputapu huri me te mata o te mowhiti hiri tetahi ki tetahi, me rite te tapeke o ngā ara reti o ia pūwāhi i runga i te mata o te mowhiti hiri ki te taputapu huri. Me huri tonu te ahunga o te nekehanga. Mā te huri tonu o te ahunga o te nekehanga ka ārai i ia kakano whakakoi kia kaua e hoki anō ki tōna ake ara i runga i te mata o te mowhiti hiri, kia kore ai e puta he tohu kakahu e kitea ana, kia kore ai hoki e piki ake te taratara o te mata o te mowhiti hiri. Hei tāpiri, mā te huri tonu o te ahunga o te nekehanga, kāore e taea te whakarite kia ōrite te tohatoha o te whakakoi, kia taea ai te tapahi i te konganuku i runga i te mata o te mowhiti hiri.
Ahakoa he uaua te nekehanga huri, ā, he nui te rerekētanga o te ahunga o te nekehanga, ka mahia tonutia te nekehanga huri i te mata honohono o te taputapu huri me te mata o te mowhiti hiri. Ahakoa he huri ā-ringa, he huri ā-mīhini rānei, ko te tika o te āhua ā-ira o te mata mowhiti hiri te mea nui e pāngia ana e te tika o te āhua ā-ira o te taputapu huri me te nekehanga huri.
3. tere huri
Ka tere ake te nekehanga huri, ka pai ake te huri. Ka tere te tere huri, ka nui ake ngā matūriki whakakoi e tika ana mā te mata o te mea mahi i ia wā, ā, ka nui ake te konganuku e tapahia ana.
Ko te tere huri i te nuinga o te wā ko te 10~240m/min. Mō ngā mea mahi e hiahia ana ki te tino tika o te huri, ko te tere huri i te nuinga o te wā kāore e neke ake i te 30m/min. Ko te tere huri o te mata hiri o te takirere e pā ana ki te rauemi o te mata hiri. Ko te tere huri o te mata hiri o te parahi me te rino maka ko te 10~45m/min; ko te mata hiri o te maitai whakapakeke me te koranu pakeke ko te 25~80m/min; ko te mata hiri o te maitai kore waikura austenitic ko te 10~25m/min.
4. te pēhanga huri
Ka piki ake te whai huatanga o te hurihanga me te pikinga ake o te pēhanga hurihanga, ā, kaua te pēhanga hurihanga e tino tiketike rawa, ko te tikanga he 0.01-0.4MPa.
I te wā e huri ana i te mata hiri o te rino maka, te parahi me te maitai kore waikura austenitic, ko te pēhanga huri he 0.1~0.3MPa; ko te mata hiri o te maitai whakapakeke me te koranu pakeke he 0.15~0.4MPa. Tangohia he uara nui ake mō te huri mata, he uara iti ake mō te huri pai.
5. Tahua huri
Nā te mea he tukanga whakaoti te huri, he iti noa iho te nui o te tapahi. Ko te rahi o te tahua huri e whakawhirinaki ana ki te tika o te mīhini me te taratara o te mata o te tukanga o mua. I raro i te kaupapa o te whakarite kia tangohia ngā tohu tukatuka o te tukanga o mua me te whakatika i te hapa āhuahanga o te mowhiti hiri, ko te iti o te tahua huri, ko te pai ake.
Ko te tikanga, me huri pai te mata hiri i mua i te huri. I muri i te huri pai, ka taea te whakapiri tika i te mata hiri, ā, ko te iti rawa o te rahi o te huri ko: ko te whānui ko 0.008~0.020mm; ko te whānui ko 0.006~0.015mm. Tangohia he uara iti ina teitei te huri ā-ringa, te pakeke rānei o te rauemi, ā, tangohia he uara nui ina iti te huri ā-ringa, te pakeke rānei o te rauemi.
He uaua ki te huri me te tukatuka i te mata hiri o te tinana takirere, nō reira ka taea te whakamahi i te huri pai. I muri i te hurihanga, me huri taratara te mata hiri i mua i te whakaotinga, ā, ko te tahua papatahi he 0.012~0.050mm.
