Uchishandisa 40Cr kana 42CrMo sechinhu chepasi, iyo chaiyo yakaumbwa isina chinhu inosangana neyakajairwa, kutendeuka, giya hobbing, kabhonitriding, kupisa kwekupisa uye kupisa, kukuya kwakanaka kwemukati denderedzwa, uye nhevedzano yekurapa ngura Kuoma kwenzvimbo yekudzima iri HRC58- HRC62, kugadzirwa kwakanaka, uye kuomarara kwemhando yekuongorora kwezvinhu zvakapedzwa.

Yakasiyana-siyana yakagadziridzwa mazino pamusoro pemagadzirirwo anowanikwa kune vashandisi kuti vasarudze kubva: herringbone zino mhando, muzinga wehuchi denderedzwa regomba mhando, gomba rakatwasuka zino musanganiswa mhando, hombe spiral helical mazino mhando, yakajairwa yakatwasuka mazino mhando, uye kuburikidza nerudzi rwezino.

High-precision concentric grinding machine processing inovimbisa kuti denderedzwa remukati re pressure roller rinonyatsoenderana nemabhengi emushandisi, pamwe chete nezvinodiwa coaxiality zvemukati nekunze denderedzwa re pressure roller.
