Dab tsi yog yam uas cuam tshuam rau lub ntsej muag polish ntawm pwm? Tam sim no cia peb qhia nws hauv kev nthuav dav.
1. Cov cuab yeej siv thiab cov lus qhia tshwj xeeb rau pwm polishing
(1) Cov cuab yeej siv rau pwm polishing muaj xws li: ntawv xuab zeb, oilstone, muaj lub log, sib tsoo muab tshuaj txhuam, cov ntaub ntawv hlau, pob zeb diamond sib tsoo koob, xyoob chips, fiber ntau oilstone, thiab lub voj voog sib tsoo tshuab.
(2) Sandpaper: 150#, 180#, 320#, 400#, 600#, 800#, 1000#, 1200#, 1500#;
(3) Oilstone: 120 #, 220 #, 400 #, 600 #;
(4) Felt log: cylindrical, round vertebral, square beak;
(5) Muab tshuaj txhuam: 1 # (dawb) 3 # (daj) 6 # (txiv kab ntxwv) 9 # (ntsuab) 15 # (xiav) 25 # (xim av) 35 # (liab) 60 # (ntsuab);
(6) Cov ntaub ntawv: square, puag ncig, tiaj tus, daim duab peb sab thiab lwm yam duab;
(7) Pob zeb diamond sib tsoo koob: feem ntau yog 3/32 kov lossis 1/8 kov, nrog lub voj voog ncig, cylindrical, ntev ncaj cylindrical, ntev puag ncig vertebral duab;
(8) Xyoob hlais: ntau yam duab yog tsim rau tus neeg teb xov tooj thiab cov pwm pwm. Nws txoj haujlwm yog nias cov ntawv xuab zeb thiab zom rau ntawm qhov chaw ua haujlwm kom ua tiav qhov xav tau ntawm qhov roughness;
(9) Fiber oilstone: 200 # (dub) 400 # (xiav) 600 # (dawb) 800 # (liab)
2. Yam cuam tshuam rau saum npoo polishing tuag
(1) Workpiece deg mob
Nyob rau hauv cov txheej txheem ntawm machining, qhov saum npoo ntawm cov khoom yuav raug puas los ntawm tshav kub, nyob rau hauv kev ntxhov siab los yog lwm yam. Kev txiav tsis zoo yuav cuam tshuam rau polishing nyhuv. Qhov saum npoo tom qab EDM yog qhov nyuaj rau kev sib tsoo ntau dua li qhov chaw tom qab machining lossis kev kho cua sov. Yog li ntawd, EDM xov yuav tsum tau saws ua ntej kawg ntawm EDM, txwv tsis pub lub nto yuav tsim ib tug hardened nyias txheej. Yog tias qhov ntsuas hluav taws xob ua tiav raug xaiv tsis raug, qhov tob ntawm cov txheej txheem cua sov tuaj yeem ncav cuag 0.4 hli. Lub hardness ntawm hardened nyias txheej yog siab dua li ntawm cov substrate thiab yuav tsum tau muab tshem tawm. Yog li ntawd, nws yog qhov zoo tshaj los ntxiv cov txheej txheem sib tsoo kom muaj lub hauv paus zoo rau polishing.
(2) Cov hlau zoo
Cov hlau zoo yog qhov yuav tsum tau ua ua ntej kom tau zoo polishing zoo. Txhua yam kev suav nrog thiab qhov pores hauv cov hlau yuav cuam tshuam cov nyhuv polishing. Txhawm rau kom ua tiav cov txiaj ntsig zoo polishing, lub workpiece yuav tsum tau cim nrog lub ntsej muag roughness ntawm polishing thaum pib ntawm machining. Thaum lub workpiece txiav txim siab xav tau daim iav polishing, nws yuav tsum xaiv cov hlau nrog polishing kev ua tau zoo thiab dhau los ntawm kev kho cua sov, txwv tsis pub cov kev xav tau yuav tsis ua tiav.
(3) Kev kho cua sov txheej txheem
Yog tias kev kho cua sov tsis tsim nyog, qhov tawv tawv ntawm cov hlau tsis sib xws lossis muaj qhov sib txawv ntawm cov yam ntxwv, uas yuav ua rau muaj teeb meem hauv polishing.
(4) Polishing tshuab
Txij li thaum polishing feem ntau ua manually, tib neeg kev txawj ntse tseem yog lub hauv paus tseem ceeb rau kev cuam tshuam qhov zoo ntawm polishing.
Nws yog feem ntau ntseeg tias polishing tshuab cuam tshuam rau saum npoo roughness. Qhov tseeb, lub tshuab polishing zoo yuav tsum tau ua ke nrog cov hlau zoo thiab cov txheej txheem kho cua sov kom tau txais cov txiaj ntsig zoo polishing; Ntawm qhov tsis sib xws, yog tias cov tshuab polishing tsis zoo, txawm tias cov hlau zoo npaum li cas, daim iav tsis tuaj yeem ua tiav.
