UFF(UltraForm Finishing)
- 5-axis CNC controller with simple to use GUI
- Fast aspheric finishing for prototyping and production
- Aspheric figure error correction using feedback from Interferometer or profilometer
- Polish directly after grind (No need to pre-polish)
- Wide variety of belts and abrasives available
Procedure and Feature of UFF
- Measure Removal Function (Integrated STIL pen, Onboard metrology) (Fig.1)
- Input Initial Figure Error (Zygo Interferometer Input, Profilometer Input)
- Optimize Polishing Tool Path (Reduce figure error, Fine control of polishing path)（Fig.2）

- Wheel size range from 8 to 100 mm in diameter (Fig.3)
- Wheel nominal hardness range from 30 to 80 Shore A
- Bound/fixed abrasives or commercial polyurethane belts with slurry (Fig.4)
- Capable of finishing a wide range of materials from optical glass to hard ceramics to sub-micron form tolerances
