Munguva yakapfuura, takatora matafura ekushandura ekunze kune imwe yeChinese, asi panguva yekushandiswa, nekuda kwemakemikari echinyorwa, kugadzira tekinoroji, saizi yejometri yemuenzaniso uye zvimwe zvinhu pamwe nekurongeka kwezviridzwa zvekuyeresa munyika dzakasiyana siyana, kuoma uye hukama hwekushandura simba kumisa hwaro uye nzira dzekugadzirisa data dzakasiyana, takaona kuti pane mutsauko mukuru pakati pemhando dzakasiyana dzekutendeuka. Pamusoro pezvo, hapana chiyero chakabatana, nyika dzakasiyana dzinoshandisa tafura yekutendeuka yakasiyana, zvichiunza nyonganiso mukuoma uye simba rekushandura hunhu.
Kubva 1965, China Metrology Scientific Research uye mamwe mayuniti akagadza Brinell, Rockwell, Vickers uye pamusoro Rockwell kuomarara mabhenji uye simba tsika pahwaro hukuru bvunzo uye ongororo tsvakurudzo, kuongorora hukama hukama pakati pekuoma kwakasiyana-siyana uye kusimba kwesimbi, kuburikidza nekugadzirwa kwekuongorora. Takagadzira yedu "black metal kuomarara uye simba rekushandura tafura" yakakodzera 9 simbi dzakateedzana uye zvisinei negiredhi resimbi. Mubasa rekuongorora, zvikamu zvinopfuura zana zvakatora chikamu, zviyero zvinopfuura zviuru zvitatu zvakagadziriswa, uye data inodarika zviuru makumi matatu yakayerwa.
Iyo data yekusimbisa yakagoverwa zvakaenzana pamativi ese eiyo shanduko curve, uye mhedzisiro yacho inoenderana nekugoverwa kwakajairika, ndiko kuti, aya matafura ekushandura anonyanya kuenderana neicho uye aripo.
Aya matafura ekushandura akafananidzwa pasi rese nematafura eshanduko akafanana enyika dze10, uye hunhu hwekutendeuka hwenyika yedu hunenge hweavhareji yekutendeuka kwenyika dzakasiyana siyana.
