Hauv kev xyaum ntau lawm, txhawm rau kom tau txais qhov zoo dua txhaj koob tshuaj tiv thaiv peening nto, peb yuav tsum pib los ntawm cov hauv qab no: muab cov khoom zoo dua qub, Ra tus nqi yuav tsum qis dua 6.3 hli; xaiv tus qauv tsim nyog steel txhaj tshuaj thiab lub siab txhaj tshuaj; Tom qab lub taub steel txhaj koob tshuaj tivthaiv muaj zog, nws tau them ib zaug nrog cov hlau me me thiab lub siab poob qis (lub zog peening lub zog tsis tuaj yeem hloov tau) kom ua tiav qhov chaw zoo. Qhov saum npoo ntawm cov seem tom qab txhaj tshuaj tag yuav tsum maj mam polished, thiab qhov nyiaj ntawm cov hlau tshem tawm saum npoo yuav tsum tswj thaum lub sijhawm polishing. Nyob rau hauv txoj kev no, lub zog cuam tshuam ntawm txhaj koob tshuaj tivthaiv peering tsis raug puas ntsoog, thiab qhov saum npoo ntawm kev ntxhib los mos tuaj yeem hloov kho.
Steel txhaj tshuaj tiv thaiv kev tiv thaiv peening yuav ua rau yas deformation ntawm qhov txau ntawm ib sab, thiab hloov qhov saum npoo ntawm ib sab. Qhov saum npoo tawv yog ib hom ntawm microscopic geometric duab yuam kev, kuj hu ua qhov me me ntawm qhov tsis sib xws. Qhov saum npoo roughness yog tib yam li cov saum npoo waviness thiab lub duab ua yuam kev. Nws belongs rau duab yam tsis ncaj ncees lawm ntawm ib sab. Qhov saum npoo tawv muaj qhov sib cuam tshuam tseem ceeb rau kev ua tiav ntawm lub tshuab ua ntu.
Cov cawv ntawm cov hlau tua rau ntawm qhov chaw saum npoo ntawm cov khoom no feem ntau nyob hauv thaj tsam ntawm Ra0.6 ～ 20mm. Yog tias tsis hloov cov txheej txheem cov txheej txheem, qhov siab dua qub qub lub zog ntawm cov khoom siv, ntau dua Ra tus nqi tom qab txhaj tshuaj tag. Kev tsim tawm tau ua pov thawj tias nyob rau hauv ib txwm muaj tshwm sim, yog tias qhov saum npoo zoo ua ntej txau qis dua 6.3 hli, txhaj koob tshuaj tiv thaiv kab mob tuaj yeem nce lossis tswj cov qub saum npoo. Yog tias thawj qhov kev ntxhib los mos saum toj no yog 6.3 hli, qhov saum npoo roughness tom qab txhaj tshuaj tag yuav txo qis.
