Peb lub cev muaj zog shafts muaj cov yam ntxwv ntawm lub zog siab, siab precision yuav tsum, zoo hnav tsis kam, zoo corrosion kuj thiab kev ua haujlwm zoo los xyuas kom meej qhov kev ua tau zoo thiab kev pabcuam lub neej ntawm lub cev muaj zog.
Kev tsim cov khoom siv lub cev muaj zog yuav tsum nruj me ntsis tswj cov khoom siv, kev siv tshuab thiab kev ua haujlwm zoo los xyuas kom meej tias qhov zoo thiab kev ua tau zoo ntawm cov ncej ua tau raws li qhov xav tau ntawm kev siv. Feem ntau xav txog cov hauv qab no:
1. Kev xaiv cov khoom siv: Lub cev muaj zog feem ntau yog ua los ntawm high-strength alloy steel lossis stainless hlau. Qhov kev xaiv ntawm cov khoom yuav tsum tau txiav txim siab raws li cov yam ntxwv xws li ib puag ncig uas siv cov khoom sib tov, kev thauj khoom, thiab qhov loj ntawm cov ncej.
2. Ncej ua tshuab: Cov txheej txheem ua haujlwm ntawm lub cev muaj zog feem ntau suav nrog ntau qhov sib txuas xws li tig, sib tsoo, thiab drilling. Cov kev sib txuas no yuav tsum nruj me ntsis tswj cov machining raug kom paub meej tias txoj kab uas hla, qhov ntev, roundness thiab lwm qhov ntev ntawm cov ncej ua tau raws li qhov yuav tsum tau ua.
3. Kev kho deg: Txhawm rau txhim kho qhov zoo ntawm qhov chaw thiab kev pabcuam lub neej ntawm lub cev muaj zog, feem ntau yuav tsum tau kho deg. Piv txwv li, sandblasting, polishing, electroplating thiab lwm txoj kev tuaj yeem siv los kho qhov chaw ntawm cov ncej.
4. Kev sib dhos thiab kev tshuaj xyuas: Tom qab kev tsim cov ncej tiav, kev sib dhos thiab kev tshuaj xyuas kuj tseem yuav tsum tau ua. Thaum sib sau ua ke, kev saib xyuas yuav tsum tau them rau qhov chaw thiab haum ntawm lub ncej kom ntseeg tau tias cov ncej tuaj yeem ntsia tau raug rau hauv qhov sib tov. Thaum lub sij hawm soj ntsuam, nws yog ib qho tsim nyog yuav tsum tau ua cov kev soj ntsuam ntawm qhov ntev, hardness, thiab axial runout kom ntseeg tau tias qhov zoo ntawm cov ncej ua tau raws li qhov yuav tsum tau ua.
