Optical glass polishing usually needs a balance between removal rate, low scratch risk and stable batch repeatability.
Key Buying Inputs
Before selecting a grade, define the glass type, current abrasive, machine, polishing pad or slurry route and target surface condition.
- Material and process step
- Micron size or W-series grade
- Surface roughness and visible scratch requirement
Product Direction
Fine monocrystalline or polycrystalline micron powder is usually tested first. The final choice depends on removal rate and scratch performance in the buyer process.
- HDY for controlled general polishing
- HDYP or HDP for fine finishing trials
- HDYM for ultra-fine slurry routes
Sample Testing
A small controlled sample is useful because polishing pressure, pad condition and slurry chemistry can change the result even with the same particle size.
