3M3125打磨机不带旋转，打磨时的运动轨迹如图(图3)所示。配合3M466LA金字塔砂碟使用，主要用于漆面疵点的去除。3M3125这种运动轨迹的设计，避免了旋转打磨（图4）过程中内外线速度不同而切削效果不同的缺点，配合金字塔砂碟更加提高了打磨后砂痕的均匀一致性，方便后道工序对砂痕的去除。其高转速（7500转）的特点，能大大提高打磨效率。这款工具的另一个特点是体积小、重量轻，使用轻巧方便，在如车门内板等其它工具不便使用的情况下均可轻松操作，特别适合亚洲人使用。Thishandypneumatictoolisdesignedforrepairingclearcoatdefectsinautomotivefinishes(AOEMbodies),aswellasfiberreinforcedplasticandwood.Designedforusewith3M™Trizact™Finesse-it™PaintRepairSystemComponents.ApplicationInformationRemovesminorpaintdefectssuchasdirt,lint,minorscratchesinAOEMbasecoat/clearcoatsystems.Designedfor3M™Trizact™Finesse-it™FilmDiscs466LAPerformanceAdvantages***alldiameterheadsizeforbettervisability,lessbuffing.Lightweight,easy-grip,rightangletoolBettervisibility,lessbuffingPrecisespeedcontrolWhatCustomersSay…Keepstherepairedspots***aller,lessareatobuff.Improveprocessefficiency-from3to2steps.Helpsreducerepaircosts.ToolspecificationMotorRPMOrbitDiameterAirflowAirPressureWeightPadSize7,5000.118inch(3mm)5.3SFM(150LPM)58.5-95.0PSI(0.40-0.65Mpa)1.06pounds(0.48kg)1.18inch(30mm))
