E tusa lava po o le a le ituaiga auala e faʻaaogaina e faʻaogaina ai, o le ai ai pea faʻailoga lelei ma faʻafefete naifi i luga o le pito i luga o vaega, ma le faʻalavelave o tumutumu ma vanu,
Taʻavale taʻavale faʻavae: O se ituaiga o faʻamaeʻaina faʻamaeʻaina, o le faʻaaogaina o le uamea i le tulaga masani o le vevela o uiga palasitika malulu, o le faʻaaogaina o meafaigaluega taʻavale e faʻamalosi ai le mamafa i luga o le mea faigaluega, ina ia mafai ai ona faʻapipiʻiina le palasitika uʻamea. tafe, faatumu i totonu o le uluai toega maualalo concave trough, ma ausia le tau roughness luga workpiece faaitiitia.Ona o le palasitika deformation o le uʻamea luga taʻavale, o le i luga o le tino malulu maaa ma thinning saito, le faia o alava mafiafia, ma le faʻavaeina o totoe o le mamafa vaega, maaa ma le malosi, ma faʻaleleia atili ai le ofuina teteʻe, corrosion teteʻe ma le fetaui o le. luga ole mea faigaluega.O le taʻavale o se auala faʻapipiʻi palasitika e aunoa ma le tipiina.
U'u paipa seamless tele tulaga lelei:
1, faʻaleleia le faʻafefeteina o luga, e mafai ona oʻo atu i le Ra≤0.08µ m pe faʻapea.
2, roundness saʻo, ellipticity e mafai ona itiiti ifo i le 0.01mm.
3, faʻaleleia le maaa o luga, faʻaumatia le faʻaleagaina o le malosi, faʻateleina le malosi HV≥4 °
4, pe a maeʻa le faʻagasologa o faʻamaʻi faʻamaʻi, faʻaleleia le malosi vaivai e 30%.
5, faʻaleleia le lelei o le fetaui, faʻaitiitia le ofuina, faʻaumiumi le ola tautua o vaega, ae faʻaitiitia le tau o le gaosiga o vaega.
