Hauv cov kev pabcuam niaj hnub aluminium machining thiab CNC txhuas qhov chaw tsim khoom, polishing yog ib kauj ruam tseem ceeb hauv kev txiav txim siab cov khoom zoo, kev ua haujlwm zoo, thiab kev lag luam tus nqi. Txawm hais tias nyob rau hauv txhuas CNC tig, CNC milling txhuas qhov chaw, los yog kev cai billet txhuas qhov chaw ntau lawm, polishing ncaj qha cuam tshuam rau ntawm qhov chaw roughness, corrosion kuj, thiab kev sib dhos ua haujlwm.
Lub ntsiab thiab lub hom phiaj tseem ceeb ntawm Polishing
Lub ntsiab lus ntawm polishing yog kom tshem tawm cov microscopic nto protrusions ntawm lub workpiece los ntawm txhua yam, tshuaj, los yog electrochemical txheej txheem, txo qhov roughness ntawm nto (Ra thiab Rz qhov tseem ceeb), thiab ua tiav ib tug du nto nrog tej yam reflective zog.
Hauv CNC-machined aluminium qhov chaw tsim khoom, lub hom phiaj tseem ceeb ntawm polishing suav nrog:
Txhim kho qhov zoo ntawm qhov chaw:tshem tawm cov cuab yeej cim thiab khawb, thiab nce Ra qhov txiaj ntsig.
Txhim kho qhov tsos:ua tiav daim iav los yog siab -gloss tiav.
Txhim khu kev ua haujlwm:Txo kev sib txhuam thiab txhim kho corrosion kuj.
Optimize kev sib dhos ua haujlwm:Txhim kho lub foob kom haum.
Npaj rau cov txheej txheem tom ntej:Muab qhov chaw zoo tagnrho rau electroplating, pleev xim, anodizing, thiab lwm yam.
Rau CNC txhuas qhov chaw factories, polishing tsis yog ib kauj ruam kom zoo nkauj xwb; nws yog ib qho tseem ceeb ntawm kev tswj cov txheej txheem thiab kev tswj kom zoo.
Polishing txheej txheem kev faib tawm thiab cov txheej txheem
1. Mechanical Polishing
Mechanical polishing yog txoj kev siv ntau tshaj plaws hauv aluminium machining qhov chaw factories. Nws ua tiav nto flatness los ntawm kev sib txhuam ntawm cov abrasive thiab workpiece.
Rough Polishing (80 #-120 # sandpaper):Ra 1.6 - 3.2 μm
Semi-Ntev polishing (240#-400#):Ra 0.4 - 0.8 μm
Polishing zoo (600 #-1200 #):Ra 0.1 - 0.4 μm
Daim iav polishing (pob zeb diamond muab tshuaj txhuam + ntaub log):Ra <0.05 μm
Haum rau txhua hom machined aluminium qhov chaw thiab CNC txhuas machining qhov chaw. Niaj hnub nimno aluminium CNC machining factories dav siv automated polishing robots kom ua tiav daim iav ruaj khov ntawm Ra 0.025 - 0.1 μm.
2. Tshuaj Polishing
Tshuaj polishing ua tiav qhov ci tiav los ntawm kev nyiam ua kom tawg me ntsis ntawm thaj chaw ntawm cov hlau. Nws yog haum rau complex geometries los yog loj - ua CNC txhuas qhov chaw.
Cov txiaj ntsig zoo:Ra 0.2 - 0.8 μm
Qhov zoo:Kev ua haujlwm siab, kev ntxhov siab -dawb, thiab muaj peev xwm ua cov txheej txheem nyuaj.
Qhov tsis zoo:Yuav tsum muaj kev tswj xyuas nruj ntawm cov tshuaj concentration thiab lub sijhawm.
3. Electrochemical Polishing (Electrolytic Polishing)
Electrochemical polishing feem ntau yog siv rau siab -kawg nto kho ntawm CNC txhuas qhov chaw thiab txhuas CNC qhov chaw, ua tiav daim iav qhov tseeb- zoo tiav.
Tus nqi Ra:<0.05 hli
Qhov zoo:Corrosion tsis kam, tsis muaj kev ntxhov siab, thiab kev ua haujlwm siab heev.
4. Cov txheej txheem polishing Advanced
Magnetorheological / Sib nqus Polishing:Haum rau aluminium precision machining.
Ultrasonic polishing:Siv rau qhov chaw zoo hauv pwm thiab cov ntaub ntawv nyuaj thiab nkig.
Atomic Force Micro-Fine Polishing (AFM):Tshwj xeeb hauv kev ua tiav cov kab noj hniav sab hauv thiab cov channel nyuaj.
Laser Polishing:Haum rau cov qauv 3D complex, txo Ra los ntawm 80%.
Cov ntsiab lus tseem ceeb tswj nyob rau hauv cov txheej txheem polishing
Quality of Pre-Processing:Qhov tseeb ntawm CNC milling txhuas feem los yog txhuas CNC tig theem ncaj qha txiav txim siab qhov ua tau thiab kev ua haujlwm ntawm polishing.
Khoom yam ntxwv:Kev cai -machined aluminium qhov chaw nrog siab purity thiab uniform microstructure muaj feem yuav ua tiav daim iav tiav.
Abrasive thiab txheej txheem Parameter:Xaiv qhov tsim nyog grit loj, kab nrawm, siab, thiab coolant yog qhov tseem ceeb rau kev ua tiav qhov zoo sib xws.
Lubrication thiab txias:Tiv thaiv kom tsis txhob overheating thiab xyuas kom ruaj khov Ra tus nqi.
Common Polishing Defects thiab Solutions
| Hom kev puas tsuaj | Ua rau | Kev daws |
| Dawb streaks / txiv kab ntxwv tev | Tshaj siab, overheating | Txo cov kab nrawm, ua kom txias |
| Kos | Cov impurities nyob rau hauv abrasive | Hloov cov ntawv xuab zeb nruj me ntsis thiab ntxuav lub workpiece |
