In industrial manufacturing and optics, the polishing of curved spherical surfaces is a crucial link. In the process of fluid polishing, the surface of the workpiece is in contact with the liquid flowing at high speed, and the abrasive particles in the liquid impact and friction on the surface of the workpiece, so as to achieve the polishing effect.
Curved spheres have complex geometries and curvature variations, so there are the following difficulties in their polishing process:
1.The traditional mechanical polishing method is difficult to adapt to the curvature change of the curved spherical surface, which is easy to cause uneven polishing.
2.The polishing process is prone to heat generation, which leads to deformation of the workpiece.
3.Residual stresses generated during the polishing process can affect the accuracy and stability of the workpiece.
For spherical polishing of curved surfaces, the fluid polishing process has the following advantages:
1.Adaptability: Fluid polishing can adapt to complex curved spherical shapes to achieve uniform polishing at changes in curvature.
2.Good cooling effect: The high-speed flowing liquid can take away the heat during the polishing process and reduce the deformation of the workpiece.
3.Reduced residual stress: The residual stress generated during the fluid polishing process is small, which is conducive to improving the accuracy and stability of the workpiece.
