在高速磨削中，磨削力小，变质层薄，不***烧，提高了加工精度和效率。南京INA轴承主轴的动静态刚度和速度特性对低噪声球轴承的磨削振动有影响。磨削系统振动小。采用随机动平衡技术，提高了轴承的抗振性和刚度。国外（中国等）磨头振动速度约为正常主轴的十分之一，这对提高砂轮和油石的切削性能和修整质量具有重要意义。Inhighspeedgrinding,thegrindingforceis***all,themetamorphiclayeristhin,anditisnoteasytoburn,whichimprovesthemachiningaccuracyandefficiency.ThedynamicandstaticstiffnessandvelocitycharacteristicsofNanjingINAbearingspindleh***eaneffectonthegrindingvibrationoflownoiseballbearings.Thegrindingsystemhaslittlevibration.Adoptingrandomdynamicbalancingtechnology,thevibrationresistanceandstiffnessofbearingareimproved.Abroad(China,etc.)grindingheadvibrationspeedisaboutone-tenthofthenormalspindle,whichisofgreatsignificancetoimprovethecuttingperformanceanddressingqualityofgrindingwheelandoilstone.目前，中国砂轮油石的主要问题是结构均匀性差，严重影响了低噪声球轴承的磨削和过加工质量，充分冷却，提高了过滤精度，提高了南京INA轴承精密进给系统的进给分辨率。降低阀杆和进给惯量，合理磨削和过加工工艺参数和流量不容忽视，磨料保留率小，形状公差和位置公差严格，中小球轴承直径不应超精密磨削；粗磨；GRI；磨削和磨削不应分开，以保证良好的表面质量。Atpresent,themainproblemofgrindingwheeloilstoneinChinaispoorstructuraluniformity,whichseriouslyaffectsthegrindingandovermachiningqualityoflownoiseballbearings,fullycooling,improvingthefilteringaccuracy,andimprovingthefeedresolutionofNanjingINAbearingprecisionfeedsystem.Reducevalvestemandfeedinertia,reasonablegrindingandover-machiningprocessparametersandflowcannotbeignored,abrasiveretentionrateis***all,shapetoleranceandpositiontoleranceisstrict,***allandmediumballbearingdiametershouldnotbeultra-precisiongrinding;roughgrinding;GRI;grindingandgrindingshouldnotbeseparatedtoensuregoodsurfacequality.***基准是为了提高南京INA轴承加工基准的精度，减少磨削误差。通过径向槽铣刀间接传动通道的超精密外径误差，分析了外径误差对通道超精密度的影响。如果工件在传输过程中出现颠簸，它会直接反射到滚道表面，影响轴承振动。ThepositioningdatumistoimprovetheaccuracyofNanjingINAbearingprocessingdatumandreducethegrindingerror.Throughtheultra-precisionouterdiametererroroftheindirectdrivechanneloftheradialgroovemillingcutter,theinfluenceoftheouterdiametererrorontheultra-precisionofthechannelisanalyzed.Iftheworkpiecebumpsduringtran***ission,itwilldirectlyreflecttotheracewaysurface,affectingbearingvibration.因此，必须采取以下措施：南京INA轴承提高***基准形状的精度；在不突出的过程中平稳地传递；使坯料误差的形状和位置不太大，特别是当残余误差较小时，会导致过大的误差。FI。端面磨削精度和超精密端面形状精度没有提高到***终质量要求，严重影响了进给速度。工作质量的一致性。Therefore,thefollowingmeasuresmustbetaken:NanjingINAbearingtoimprovetheaccuracyofthepositioningreferenceshape;intheprocessofnon-prominent***oothtran***ission;sothattheshapeandpositionoftheblankerrorisnottoolarge,especiallywhentheresidualerroris***all,willleadtoexcessiveerror.FI.Theprecisionofendgrindingandtheshapeprecisionofultra-precisionendfacearenotimprovedtothefinalqualityrequirement,whichseriouslyaffectsthefeedspeed.C***istencyofworkquality.因此，南京INA轴承由高性能、高稳定性机床系统组成的自动线磨削方法***适合于超低噪声球轴承加工，避免了颠簸，减少了传动误差，消除了人为因素，提高了加工效率和质量。保持南京INA轴承一致性，降低生产成本，提高企业效率。Therefore,theautomaticlinegrindingmethodofNanjingINAbearing,whichiscomposedofhighperformanceandhighstabilitymachinetoolsystem,ismostsuitablefortheprocessingofultra-lownoiseballbearings.It***oidsbump,reducestran***issionerror,eliminateshumanfactors,andimprovesprocessingefficiencyandquality.Maintainthec***istencyofINAbearingsinNanjing,reduceproductioncostsandimproveenterpriseefficiency.文章来自：南京SKF轴承www.wh-Thearticleisfrom:NanjingSKFbearingwww.wh-文章来自：南京INA轴承a-Thearticleisfrom:NanjingINAbearinga-文章来自：南京NSK轴承Thearticleisfrom:NanjingNSKbearing***：524085168电话：0510-81207777手机：13311666672)
