How Random Orbital Motion Improves Photonic Component Polishing
May 18, 2026, 7:58 p.m.
Consistent polishing results depend on more than the polishing film itself. Motion, contact pattern, pressure, and process control all play important roles in how evenly material is removed from a photonic component. For applications involving fiber arrays, waveguides, PICs, bare fibers, fiber optic connectors, and other precision optical components, repeatability is critical.
KrellTech’s NOVA™ polishing systems use a random orbital motion platen to help create a more uniform polishing process. Instead of concentrating wear in one repeated path, random orbital motion helps distribute contact across the polishing film. This supports more consistent film use, reduces localized wear, and provides a stronger foundation for repeatable photonic component polishing.

What Is Random Orbital Motion in Polishing?
Random orbital motion refers to a polishing motion that avoids repeatedly following the exact same path across the polishing surface. In photonic component polishing, this helps prevent one area of the polishing film from experiencing excessive localized wear.
By distributing motion more evenly across the film, the platen helps operators maintain a more consistent polishing surface throughout the process. This is especially useful when working with precision components where endface quality, geometry, and material removal must be carefully controlled.
More Uniform Polishing Film Wear
One of the key benefits of random orbital motion is more uniform polishing film wear. When a component follows the same path repeatedly, certain areas of the film may degrade faster than others. This can create uneven polishing behavior over time.
NOVA’s random orbital motion platen helps spread contact across the film, reducing the chance that one repeated track or localized area takes on most of the wear. More even film use can help operators maintain a more stable polishing process from one step to the next.
Reduced Localized Wear Patterns
Localized film wear can affect consistency, especially in workflows where repeatability is important. If one area of the polishing film becomes worn faster than the surrounding surface, it may influence material removal, surface quality, or the overall polishing result.
Random orbital motion helps reduce these localized wear patterns by minimizing repeated contact in one narrow path. This supports a more balanced polishing surface and helps operators better control the process over time.
Longer Consumable Life
Because random orbital motion helps distribute contact more evenly across the polishing film, it can also help extend the usable life of polishing consumables. Instead of wearing out one specific section of the film quickly, more of the available polishing surface can be used throughout the process.
For labs, production environments, and process development teams, longer consumable life can help improve workflow efficiency and reduce unnecessary film changes. It also supports better process continuity, especially when customers are working through multi-step polishing procedures.
Fewer Polishing Artifacts
Repetitive motion patterns can contribute to polishing artifacts such as grooves, flat spots, or repeated scratch patterns. These artifacts can be especially problematic for photonic components where endface quality and geometry directly affect performance.
By reducing repetitive polishing paths, random orbital motion can help minimize these types of artifacts. The result is a more consistent polishing action that supports cleaner, more repeatable outcomes.
Better Process Repeatability
For photonic component polishing, repeatability is one of the most important goals. Operators need to know that a process can be followed consistently from part to part, whether they are working in R&D, prototyping, or production.
NOVA’s random orbital motion platen supports repeatability by helping create a more uniform polishing environment. More consistent film wear, reduced localized degradation, fewer artifacts, and improved consumable usage all contribute to a more controlled process.
