How it Works

How MRF® Works

Machine Schematic

A workpiece is installed at a fixed distance from a moving spherical wheel. An electromagnet located below the wheel surface generates a magnetic field in the gap between the wheel and workpiece. When the MR fluid is delivered to the wheel, it is pulled against the wheel surface by the magnetic field gradient and becomes a subaperture polishing tool. A sophisticated computer program determines a schedule for varying the position of the workpiece as it sweeps through the polishing zone, in either a rotating or raster pattern.

through every step of the automated process. Stability and predictability reign throughout.

Optical surface errors are fully characterized on an interferometer and transferred to the Q22 MRF system

  • User-friendly software calculates the optimal toolpath required to correct the surface errors
  • Pre-run setup is verified with an integrated simulation
  • Real-time progress bars monitor status during polishing
  • Advanced analysis features evaluate final results
