Thaum cov txheej txheem polishing raug tso tseg, nws yog ib qho tseem ceeb heev kom ntseeg tau tias qhov chaw ntawm lub workpiece yog huv si thiab ua tib zoo tshem tawm tag nrho cov abrasives thiab lubricants. Tom qab ntawd ib txheej ntawm pwm los tiv thaiv xeb yuav tsum tau txau rau ntawm qhov chaw.
4. Yam cuam tshuam rau pwm polishing zoo
Txij li cov tshuab polishing feem ntau ua tiav manually, polishing tshuab tseem yog qhov tseem ceeb cuam tshuam rau polishing zoo. Tsis tas li ntawd, nws tseem muaj feem xyuam rau cov khoom pwm, qhov chaw saum npoo ua ntej polishing, txheej txheem kev kho cua sov, thiab lwm yam. Cov hlau zoo yog qhov yuav tsum tau ua ua ntej rau polishing zoo. Yog tias qhov tawv tawv ntawm cov hlau tsis sib xws lossis muaj qhov sib txawv ntawm cov yam ntxwv, polishing nyuaj yuav tshwm sim ntau zaus. Ntau cov khib nyiab thiab qhov pores hauv cov hlau tsis zoo rau polishing.
1. Qhov cuam tshuam ntawm qhov sib txawv hardness ntawm polishing txheej txheem
2. Ua kom muaj zog ua kom sib tsoo nyuaj, tab sis qhov roughness tom qab polishing txo qis. Raws li lub hardness nce, lub sij hawm polishing yuav tsum tau ua kom qis roughness nce raws li. Nyob rau tib lub sij hawm, lub hardness nce thiab muaj peev xwm ntawm over-polishing txo.
3. Kev cuam tshuam ntawm qhov chaw ua haujlwm saum npoo ntawm cov txheej txheem polishing
Thaum lub sij hawm crushing txheej txheem ntawm steel txiav machinery, qhov saum npoo yuav puas vim cua sov, sab hauv kev nyuaj siab los yog lwm yam. Kev txiav tsis raug cai yuav cuam tshuam rau polishing nyhuv, yog li yuav tsum tau ua tiav CNC ceev, thiab kev txiav cov nqi yog tswj ntawm 0.05-0.07mm.JN Qhov chaw tom qab EDM Kev ua haujlwm yog qhov nyuaj dua rau kev sib tsoo tshaj qhov saum npoo tom qab kev ua haujlwm zoo tib yam lossis kev kho cua sov. Yog li ntawd, kev hnav khaub ncaws zoo EDM yuav tsum tau siv ua ntej kawg ntawm kev ua EDM, txwv tsis pub txheej txheej tawv tawv yuav tsim rau saum npoo. Yog tias EDM tiav cov lus qhia tshwj xeeb raug xaiv tsis raug, qhov tob ntawm cov txheej txheem cua sov tuaj yeem ncav cuag li 0.4 hli. Lub hardness ntawm txheej hardened yog siab tshaj qhov yooj yim hardness thiab yuav tsum tau muab tshem tawm. Yog li ntawd, nws yog qhov zoo tshaj plaws los ntxiv cov txheej txheem sib tsoo kom tshem tawm cov txheej txheej puas lawm thiab tsim cov hlau ntxhib sib npaug, uas muab lub hauv paus zoo rau polishing.
12. Kev saib xyuas ntawm high-gloss pwm
1. Qhov saum npoo ntawm cov pwm ua haujlwm feem ntau yuav tsum tau them nrog cov khoom siv qib siab los tiv thaiv xeb lossis ntim nrog cov yas qhwv kom tiv thaiv kev sib cuag nrog huab cua thiab ua rau xeb;
2. Tiv thaiv kom tsis txhob muaj cov khib nyiab lossis txhais tes los ntawm kev sib cuag ncaj qha nrog cov kab noj hniav;
3. Thaum ntxuav daim iav saum npoo, cov ntaub so ntswg high-density yuav tsum tau muab txau nrog cov tshuaj ntxuav thiab txhuam kom zoo los ntawm sab saum toj mus rau hauv qab, thiab tsis tuaj yeem txhuam rov qab; kev kho mob paj rwb thiab ntaub strips tsis tuaj yeem siv; rab phom tsis tuaj yeem siv los tshuab ncaj qha rau ntawm qhov chaw ua haujlwm, vim tias huab cua nyob hauv lub trachea yog Debris thiab noo noo tuaj yeem ua rau qhov chaw ua haujlwm puas tsuaj.
4. Tom qab txhua qhov pwm tsim los yog pwm sim, cov dej channel ntawm cov pwm yuav tsum tau tshuab kom huv si nrog rab phom los tiv thaiv cov pwm core los ntawm xeb.
