Nws yog ib hom kev ua haujlwm siab lub teeb, uas siv cov yam ntxwv ntawm cov yas txias ntawm cov hlau ntawm qhov kub thiab txias, thiab siv cov cuab yeej dov los siv lub siab ntawm qhov chaw ua haujlwm, kom cov hlau ntawm cov hlau nto ua cov yas ntws thiab ntim. tus thawj Nyob rau hauv qhov zawj, txo qhov roughness ntawm lub workpiece. Tsis muaj teeb meem li cas lub raj dov tau ua tiav, cov pob me me thiab cov cim tsis sib xws yuav tshwm sim rau ntawm qhov chaw.
Vim tias cov yas deformation ntawm cov raj honed ua kom muaj kev ntxhov siab thiab muaj zog, yog li kev txhim kho lub zog tsis kam, corrosion tsis kam thiab kev sib koom tes ntawm lub dov tube nto pw ua ke. Rolling yog ib txoj kev ua cov yas uas tsis yog txiav. Tsis siv neeg txiav tshuab muaj kev nyab xeeb, yooj yim, thiab nws tso cai rau kev tswj xyuas qhov tseeb.
1. Txhim kho qhov roughness ntawm qhov chaw, qhov roughness tuaj yeem ncav cuag Ra tsawg dua li ntawm 0.08μm.
2. Kho qhov roundness, lub ellipticity yuav tsawg dua 0.01mm.
3. Txhim kho qhov tawv tawv, tshem tawm kev ntxhov siab thiab deformation, thiab qhov hardness yuav nce los ntawm HV lossis siab dua 4 degrees.
4. Tom qab kev ua tiav, cov txheej txheem kev ntxhov siab seem ntxiv thiab lub zog qaug zog nce 30 feem pua.
5. Txhim kho kev sib koom tes zoo, txo qhov hnav thiab tsim kua muag, ua kom lub neej ua haujlwm ntev ntawm cov khoom, tab sis txo cov nqi ntawm cov khoom.
