Cov txheej txheem polishing yooj yim rau cov pwm yas kom ua tiav siab- cov txiaj ntsig zoo polishing, nws yog ib qho tseem ceeb uas yuav tsum muaj cov cuab yeej polishing zoo thiab cov khoom siv zoo, suav nrog cov roj zeb, ntawv xuab zeb, thiab pob zeb diamond polishing muab tshuaj txhuam.
Cov txheej txheem polishing dav dav rau cov pwm yas yog raws li hauv qab no:
Fine Polishing Fine polishing feem ntau siv pob zeb diamond polishing muab tshuaj txhuam. Yog tias siv lub log polishing sib xyaw nrog pob zeb diamond polishing hmoov lossis muab tshuaj txhuam, cov txheej txheem polishing yog 9μm (# 1800) ~ 6μm (# 3000) ~ 3μm (# 8000) . 9μm pob zeb diamond polishing paste thiab polishing log siv tau los tshem tawm cov plaub hau khawb tawm los ntawm # 1200 thiab # 15. Tom ntej no, polishing yog ua los ntawm kev xav thiab pob zeb diamond polishing muab tshuaj txhuam, nyob rau hauv ib theem ntawm 1μm (# 14000) ~ 1/2μm (# 60000) ~ 1/4μm (# 100000). Cov txheej txheem polishing uas xav tau qhov tseeb ntawm 1μm lossis siab dua tuaj yeem ua tiav hauv chav polishing huv hauv lub rooj ua haujlwm pwm. Txhawm rau polishing meej dua, qhov chaw huv huv yog qhov tseem ceeb. Plua plav, pa luam yeeb, dandruff, thiab qaub ncaug tuaj yeem ua rau lub siab ua haujlwm siab - polished nto tiav tom qab teev ua haujlwm.
Rough Polishing: Ntog tom qab milling, EDM, thiab kev sib tsoo tuaj yeem polished siv lub ntsej muag polisher lossis ultrasonic grinder nrog ceev ntawm 35,000-40,000 rpm. Ib txoj hauv kev yog siv Φ3mm txoj kab uas hla, WA #400 log kom tshem tawm cov txheej EDM dawb. Qhov no yog ua raws li los ntawm tes oilstone polishing, siv ib tug sawb ntawm oilstone nrog kerosene raws li ib tug lubricant los yog coolant. Qhov kev txiav txim dav dav ntawm daim ntawv thov yog # 180 ~ # 240 ~ # 320 ~ # 400 ~ # 600 ~ # 800 ~ # 1000. Ntau lub tuam txhab pwm xaiv pib nrog #400 kom txuag sijhawm.
Semi-Fine Polishing: Semi- polishing zoo tsuas yog siv cov ntawv xuab zeb thiab roj av. Cov lej grit rau cov ntawv xuab zeb yog raws li hauv qab no: # 400 ~ # 600 ~ # 800 ~ # 1000 ~ # 1200 ~ # 1500. Hauv kev xyaum, #1500 sandpaper tsuas yog tsim rau cov hlau tawv tawv (52HRC thiab siab dua), thiab tsis yog rau cov hlau ua ntej- tawv tawv, vim nws tuaj yeem ua rau kub hnyiab ntawm cov khoom ua ntej- hardened steel.
Fine Polishing: Zoo polishing nrog polishing compound ntawm 8000 lossis 10000 grit yuav ua tiav daim iav tiav.
