Kev tsim cov txheej txheem ntawm lub qhov pom txuas txuas feem ntau siv 45 # steel, 40Cr, lossis alloy structural steel tuav. Tom qab txiav thiab blanking, ua ntej tig yog ua los tsim cov qauv yooj yim ntawm cov pas nrig txuas, nrog rau txoj kab uas hla ntawm tus pas nrig, qhov kawg txuas, thiab cov qauv ntawm lub taub hau cutter mounting txoj hauj lwm. Cov theem no tsuas yog tswj cov qhov yooj yim qhov tseeb.
Siv tshuab lathes, milling tshuab, los yog CNC machining cov cuab yeej, cov khoom tseem ceeb xws li lub hexagonal shank thiab threaded txuas kawg yog precision machined los xyuas kom meej qhov haum qhov tseeb nrog lub laum chuck thiab qhov pom. Tib lub sijhawm, coaxiality thiab roughness ntawm qhov chaw yog tswj kom txo tau eccentricity thiab kev co thaum lub sij hawm siab -kev sib hloov ceev.
Cov pas txuas txuas feem ntau xav tau kev kho cua sov (quenching + tempering) txhawm rau txhim kho tag nrho lub zog thiab tawv, ua kom nws tuaj yeem tiv taus cov khoom hnyav hnyav yam tsis muaj deformation lossis tawg. Rau siab- cov khoom kawg, kev kho qhov chaw hauv cheeb tsam kuj tseem tuaj yeem siv los txhim kho kev hnav.
Cov kev kho saum npoo feem ntau suav nrog blackening, galvanizing, lossis chrome plating los txhim kho xeb. Cov khoom tiav lawm kuj yuav tsum tau kuaj xyuas coaxiality, kuaj hardness, thiab kev sib dhos kuaj kom ntseeg tau tias kev sib txuas ruaj khov, kev ua haujlwm du, thiab txhim khu kev ruaj ntseg hauv kev siv tiag tiag.
