介绍了一种复杂曲面光整加工机械──三坐标数字化磁粒光整加工机床。该机床通过对复杂曲面的数字化测量和自动编程，得到磁极与工件保持一定间隙沿工件表面运行的加工轨迹，利用吸附在工具磁极上面的磁性磨料为工具，通过磁极带动磁粒沿工件表面作高速旋转，从而实施对工件表面的光整加工。该机床的研制成功实现了复杂曲面光整加工的自动化。
This paper introduces a complex surface finishing machinery ─ ─ coordinate three-dimensional magnetic particle finishing machine. The machine tool through the digital measurement of complex surfaces and automatic programming, get the pole and the workpiece to maintain a certain gap along the workpiece surface running trajectory, the use of magnetic tools adsorbed on top of the magnetic tool as a tool, driven by the magnetic pole along the workpiece surface for high speed Rotation, so as to implement the finishing of the workpiece surface. The successful development of this machine has enabled the automation of complex surface finishing.
