Machined smooth finishing ua ib tug nto nrog arithmetic txhais tau tias roughness, los yog Ra, ntawm 1.6 μm (63 μin).Zoo li machined tiav, machined du tiav kuj muab ntse ntug tshem tawm thiab deburring rau ib feem.Txij li qhov saum npoo yog smoother dua li tus qauv tiav nto, cov qhab nia thiab qhov tsis zoo yog qhov tsis tshua pom tseeb.Machined du tiav yog tsis muaj nrog kom hniav zoo nkauj tiav.

Qee qhov yuav tsum tau ua kom zoo dua qhov ua tiav dua li qhov muab los ntawm cov txheej txheem tiav.Nyob rau hauv cov ntaub ntawv no, ib tug ntxiv machining lag luam yog nqa tawm los txo cov nto roughness mus rau ib tug txaus tus nqi.Hauv cov khoom tsim nrog CNC tshuab, xws li kev ua haujlwm feem ntau tuaj yeem ntxiv rau cov txheej txheem tsim khoom kom txuag sijhawm.Rau cov khoom uas tsis yog-CNC cov cav tov lossis ntau lub tshuab, CNC machining yog siv rau kev ua haujlwm du tom qab cov khoom tiav thiab ib feem yog npaj txhij.
