Troubleshooting

Inside of ring remains dull

A small inside tool may create lower surface speed and lower temperature than the outside wheel route.

A bright ring exterior surrounding an evenly dull inner bore under close inspection.

Symptoms

  • Outside of the ring reaches gloss, but the inside remains dull.
  • The same compound seems to work outside but not inside.

Likely causes

  • Small tool diameter and lower surface speed may keep the working zone below the heat needed for a standard polishing paste to become fully mobile.

Checks

  • Compare the outside wheel diameter with the inside tool diameter.
  • Check rpm and whether the inside tool feels dry or underactive.

Recommended fixes

  • Treat the inside as a small-tool / low-temperature polishing problem.
  • Inspect tool diameter and rpm.
  • Consider LUXI Green or LUXI Purple depending on required aggressiveness and geometry.

Prevention

  • Record inside-tool diameter and rpm during process development.
  • Do not assume the inside route behaves like the outside 6 inch wheel route.
