卧式磁性研磨机床(进给机构)设计 摘要 光整技术和研磨技术在加工过程中状态是自由的，（在一定运动形式、作用压力实现）随机的，游离的。磨床上的磨削。磁性研磨是借住磁场，用磁实现对工件的加工。研磨压力的形式为以加工磁性材料的外圆表面为例：为加工区域内单颗磨粒的受力状况。工件的高速回转运动和工件的轴向往复运动。进给运动为使新的金属不断投入切削的运动。进给传动系的变速机构是用来改变进给量大校进给传动是恒转矩传动，各传动件的计算转速是其最高转速。进给传动的变速范围：为缩短进给传动的稳定性，进给系统的末端常采用降速很大的传动机构，如：进给传动系采用传动间隙消除机构。快速空程传动的采用。最佳降速比的确定：齿轮传动间隙的消除。滚珠丝杠是将旋转运动转换成执行件的直线运动的运动转换机构。 关键词光整研磨卧式磁性研磨进给传动 Abstract The tech
