Ukusonta kwesinyithi, okwakwaziwa njengokubumba okanye ukusonta, yinkqubo yokwenza isinyithi ebandakanya ukujikelezisa idiski yesinyithi okanye ityhubhu kwilathe ngelixa usebenzisa uxinzelelo ngesixhobo ukuyibumba ibe yifom efunwayo.Inkqubo isetyenziswa ngokuqhelekileyo ukwenza iimilo ze-cylindrical okanye i-conical ezifana nezitya, i-vases, kunye ne-lampshades, kunye neejometri ezinzima ezifana ne-hemispheres kunye ne-paraboloids.
Ngethuba lokujikeleza kwesinyithi, i-disc yensimbi okanye ityhubhu ibotshelelwe kwi-lathe kwaye ijikelezwe ngesantya esiphezulu.Isixhobo, esibizwa ngokuba sisipina, sicinezelwa kwintsimbi, yenze ukuba ihambe kwaye ithathe ubume besixhobo.I-spinner inokuthi ibanjwe ngesandla okanye ifakwe kwi-lathe.Inkqubo iphinda iphindwe kaninzi, kunye nemilo ephuculwe ngokuthe ngcembe ngokupasa nganye kuze kube yifomu yokugqibela.
Ukujikeleza kwesinyithi kunokwenziwa kusetyenziswa uluhlu olubanzi lwesinyithi, kubandakanywa i-aluminiyam, ubhedu, ubhedu, intsimbi engatyiwa, kunye ne-titanium.Idla ngokusetyenziswa ekwenzeni amacandelo e-aerospace, i-automotive, kunye nemizi-mveliso yokukhanyisa, kunye neenjongo zokuhombisa kunye nezobugcisa.
