Txhaj pwm polishing muaj ob lub hom phiaj; Ib qho yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau pwm, nws yog qhov tsim nyog los ua kom cov pwm ua kom du, ua kom lub ntsej muag ntawm cov khoom tsim los ntawm cov pwm du, huv si, zoo nkauj, thiab zoo nkauj. Lwm qhov yog ua kom yooj yim rau pwm rau demould, kom cov yas tsis lo rau pwm thiab tsis tuaj yeem tshem tawm.
Kev ceev faj rau polishing txhaj pwm yog raws li nram no:
(1) Thaum machining pwm kab noj hniav tshiab, qhov chaw ua haujlwm yuav tsum tau kuaj xyuas ua ntej, thiab qhov chaw yuav tsum tau ntxuav nrog cov roj av kom tsis txhob muaj cov av lo rau ntawm qhov chaw ntawm cov roj, uas ua rau poob ntawm kev ua haujlwm.
(2) Thaum sib tsoo cov kab ntxhib, nws yuav tsum ua raws li qhov kev txiav txim ntawm qhov nyuaj ua ntej thiab tom qab ntawd yooj yim. Tshwj xeeb tshaj yog rau qee qhov nyuaj tuag, qhov tob hauv qab yuav tsum tau grinded ua ntej,
(3) Qee qhov workpieces yuav muaj ntau daim sib dhos thiab polished ua ke. Nws yog ib qho tsim nyog yuav tsum tau ua ntej polish cov ntxhib los yog cov cim ntawm ib qho chaw ua haujlwm, thiab tom qab ntawd kho thiab txhuam tag nrho cov workpieces kom txog thaum tus.
(4) Rau workpieces nrog loj los yog sab saum npoo, siv ib tug oilstone tshem tawm cov ntxhib kab, thiab ces siv ib tug ca steel ntawv rau lub teeb kis tau tus mob kuaj xyuas seb puas muaj ib tug tsis sib xws los yog undercut defects. Yog hais tias muaj undercuts, nws yuav ua rau nyuaj rau demolding lub workpiece los yog strain lub workpiece.
(5) Txhawm rau tiv thaiv kev saib xyuas los ntawm kev them nyiaj rau cov xwm txheej uas cov pwm ua haujlwm tau tsim undercuts lossis muaj qee qhov chaw sib txuas uas yuav tsum tau tiv thaiv, nws tuaj yeem muab tso rau ntawm sawb lossis ntawv xuab zeb ntawm ntug, uas tuaj yeem ua tiav qhov zoo tagnrho. tiv thaiv nyhuv.
(6) Thaum sib tsoo cov pwm saum npoo, rub nws rov qab, thiab rub tus kov ntawm cov roj zeb kom tiaj tus li ua tau, tsis pub tshaj 25 degree; Vim qhov loj inclination, lub zog yog tsav los ntawm sab saum toj mus rau hauv qab, uas yuav yooj yim ua rau ntau coarse kab raug grinded rau ntawm workpiece.
(7) Yog hais tias qhov chaw ntawm lub workpiece yog polished nrog tooj liab los yog xyoob chips nias tiv thaiv daim ntawv abrasive, daim ntawv abrasive yuav tsum tsis txhob tshaj qhov chaw ntawm lub cuab tam, txwv tsis pub nws yuav zom rau qhov chaw uas yuav tsum tsis txhob yuav hauv av.
(8) Cov duab ntawm cov cuab yeej sib tsoo yuav tsum nyob ze rau qhov zoo ntawm cov pwm kom ntseeg tau tias cov khoom ua haujlwm tsis deformed los ntawm kev sib tsoo.
