Magnetorheological finishing Solution

How dose Magnetorheological finishing work?

Using magnetorheological fluid (made of magnetic particles, base liquid, surfactant as the matrix, and adding polishing powder) as a polishing tool, rheological characteristics are generated under the action of a controllable magnetic field, and a magnetic fluid with controllable viscosity is formed. Surface errors of optical parts are quantitatively removed at fixed points to achieve efficient and high-precision shape modification.

  • High-efficiency, low-damage processing
  • Five-axis linkage processing, positioning accuracy up to micron level
  • Brand new closed-loop control algorithm that compensates for motion errors in real-time across all axes.
  • Configure the three-coordinate probe: detect the position of the workpiece in place.
  • Three-coordinate/intelligent positioning: use standard spheres and other references to correct mechanical installation errors of each axis.
  • Three-coordinate/tool setting: verify workpiece positioning, tool setting, and processing parameters, and perform real-time correction.
