Kev ntsuas kom txo cov iav Loj Siab Quenching Kev hloov pauv

1. Qee lub tshuab cuab yeej siv tshuab xav kom lub qhov sab hauv shrinks <0.005mm, lossis <0.01mm tom qab iav quenching. Feem ntau, tom qab high-frequency quenching, lub puab lub qhov shrinks mus txog 0.01-0.05mm; qee qhov chaw ua haujlwm preheat lub puab qhov ntawm lub spline ua ntej. Tom qab ntawd quench cov hniav sab nrauv; qee qhov chaw ua haujlwm ntxiv cov txheej txheem kub kub kub tom qab kev sib hloov ntawm cov iav tuab tuab, thiab tom qab ntawd ntxiv cov khoom siv high-frequency normalizing kom muaj kev ntxhov siab, thiab tom qab ntawd ua tiav, kos duab splines, txiav cov hniav, shaving hniav, siab zaus quenching thiab kub tsis tshua muaj. tempering tuaj yeem tswj tau qhov shrinkage ntawm lub puab qhov nyob rau hauv 0.005mm.

2. Rau cov iav quenched los ntawm cov hniav, qhov kawg quenched iav hniav yog deformed heev. Yog li ntawd, txoj kev ntawm cov hniav-los ntawm-tus hniav quenching kom txo deformation yog ua quenching hloov, uas yog, cais ib los yog ob tug hniav rau quenching, thiab hniav-los ntawm-tus hniav quenching txo cov deformation ntawm lub quenched iav.
