Qhov ua rau thiab kev daws ntawm burr hauv kev sib tsoo

Kev sib tsoo yog ib txoj hauv kev tseem ceeb heev, uas tuaj yeem siv los txhim kho qhov tseeb qhov tseeb, qhov zoo ntawm qhov chaw thiab kev pabcuam lub neej ntawm cov khoom ua haujlwm. Txawm li cas los xij, burrs tuaj yeem tshwm sim thaum sib tsoo, cuam tshuam rau qhov zoo thiab kev ua haujlwm ntawm lub workpiece. Niaj hnub no, peb yuav txheeb xyuas qhov ua rau thiab kev daws teeb meem ntawm burrs hauv kev sib tsoo los ntawm kev sib tsoo log, kev ua haujlwm thiab kev ua haujlwm tsis zoo.

1. Sib tsoo lub log

Lub cim ntawm burrs muaj feem xyuam rau kev xaiv thiab siv cov sib tsoo log. Nov yog qee qhov ua rau muaj feem cuam tshuam rau kev sib tsoo log:

Thicker sib tsoo lub log: kev siv lub log sib tsoo ntau dhau tuaj yeem ua rau txiav ntau dhau ntawm qhov chaw ua haujlwm thaum sib tsoo, ua rau muaj burrs. Nyob rau tib lub sijhawm, kev sib tsoo hnyav dhau lub log sib tsoo nto zoo yuav tsis siab heev.

Siab dua los yog qis dua hardness ntawm kev sib tsoo log: siab dua los yog qis dua hardness ntawm kev sib tsoo log yuav cuam tshuam rau tiam ntawm burrs. High hardness ntawm kev sib tsoo log yuav ua rau kom muaj zog txiav thiab ua rau muaj peev xwm ntawm burrs; Lub hardness ntawm lub sib tsoo log yog tsawg heev, uas yuav ua rau ntau tshaj txiav nyob rau hauv lub workpiece nto, thiab nws kuj yog ib qho yooj yim los tsim burrs.

Kev sib tsoo lub log tsis zoo: Yog tias lub log sib tsoo hnav tsis zoo, xws li kev txiav qhov tob tob dhau thaum hnav khaub ncaws, kev pub ceev nrawm dhau, thiab lwm yam, nws yuav ua rau cov trenches sib sib zog nqus los yog ua pob ntawm qhov sib tsoo, thiab ces tsim burrs.

Kev sib tsoo lub log tsis zoo: Thaum lub log sib tsoo ceev dhau lawm, qhov kub ntawm qhov chaw sib tsoo yuav nce, thiab oxidation thiab hlawv tshwm sim ntawm qhov chaw ua haujlwm yuav nce ntxiv, ua rau burrs ntawm qhov chaw ua haujlwm. Tsis tas li ntawd, qhov kev kub ceev ntawm kev sib tsoo lub log kuj tseem yuav ua rau lub sijhawm sib cuag ntawm lub log sib tsoo thiab cov khoom ua haujlwm luv luv, cov nyiaj sib tsoo raug txo, thiab cov burrs kuj raug tsim. Thaum lub sib tsoo log ceev tau qis dua, qhov sib tsoo cheeb tsam sib sau ntau dua kub, txiav ntug ntawm qhov sib tsoo log yuav maj mam passivate, ua rau muaj kev sib tsoo quab yuam, thiab lub workpiece nto kuj yog burrs.

Yog li ntawd, txhawm rau txo cov tiam ntawm burrs, nws yog ib qho tsim nyog yuav tau xaiv cov kev sib tsoo uas tsim nyog raws li cov khoom siv ua haujlwm thiab qhov kev sib tsoo uas yuav tsum tau ua, thiab xyuas kom meej tias qhov hardness, hnav khaub ncaws lub xeev thiab ceev ntawm lub log sib tsoo ua tau raws li qhov yuav tsum tau ua. Nyob rau tib lub sijhawm, nyob rau hauv tus txheej txheem ntawm kev siv, nws tseem yuav tsum tau ua tib zoo saib xyuas lub xeev ntawm kev sib tsoo log, hnav khaub ncaws raws sij hawm thiab hloov pauv kom tsis txhob burrs.
