从计算得出的浮动上模作往复周期摆动时工件表面上任一点的相对线速度表达式看出，线速度幅值是一个多变量函数。在这些参数中，只有主轴转速与摆架摆速是机床本身的固有参数。从均匀抛光角度出发，提出主轴转速与摆架摆速匹配的观点，为抛光机换代设计提供了依据。 From the calculated floating upper mold reciprocating periodic oscillation at any point on the surface of the relative linear velocity expression shows that the linear velocity amplitude is a multivariable function. Among these parameters, only the spindle speed and pendulum speed are the intrinsic parameters of the machine itself. From the point of view of uniform polishing, this paper puts forward the viewpoint that the spindle speed matches with the pendulum speed, which provides the basis for the replacement design of the polishing machine.
