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.
