It uses the rheological characteristics of liquid-magnetic abrasive tool to finish surface of parts. It has typical fluidness when there is no external magnetic field around it. But when a strong magnetic field is applied, the viscosity of liquid-magnetic abrasive tool will increase quickly, and it will show the characteristics that resemble to solid.

该技术是利用液体磁性磨具的流变特性来实现对零件表面光整加工的，液体磁性磨具在没有外部磁场的情况下表现为一般的流体状态，具有良好的流动性，而一旦施加外部磁场它的粘度会迅速增加，表现出类似固体的特性，这就是液体磁性磨具的流变性。

Because the workpiece is in dynamic balance, the resultant moment acting on it should be zero. Introducing the moment from lapping tool and press head a moving differential equation is built. In this equation only workpiece rotating speed is unknown. It means that workpiece rotating speed can be got by this equation. Since there is a transcendental function in integral function of the equation an analytic result can not be got, only digital result can be got by a computer. Thus a change rule of workpiece rotating speed with lapping parameters is known, e.g. the radius of press disc ball socket, radius of press head ball, the distance between the workpiece rotating axis and lapping tool rotating axis, workpiece radius, modulus of elasticity of the press head and press disc, friction coefficients between the lapping tool and workpiece, and between the head and disc, pressure between the lapping tool and workpiece and pressure between the press head and press disc.

因工件处于动态平衡状态，其上所受到的来自于磨具和压头的力矩应相等，将二力矩表达式联立，建立工件运动微分方程，该方程中只有工件的旋转角速度是未知量，因此可以求出工件旋转角速度，但该方程积分式中含有超越函数，得不出解析解，只能通过计算机求出数值解，得出工件旋转角速度随各研磨参数的变化规律，如压盖球座半径、压头的球头半径、工件回转中心相对磨具回转中心的偏心距、工件半径、压头和压盖材料的弹性模量、磨具与工件间的摩擦系数、压头压盖间的摩擦系数、磨具与工件间的压强、压头压盖间的压力等。
