Optical Glass Pellets
ZF heavy flint glasses are softer and lead-bearing, and prone to scratching and orange peel. A softer formulation lowers the stress of each cutting point while keeping removal rate usable.
- Typical use
- ZF flint · low-scratch formulation
- Customisation
- If your process shows orange peel or scratches, send the material and measured roughness and we will adjust bond hardness and grit combination.
- MOQ & lead time
- Standard sizes from stock or 3–7 working days. Custom parts 7–15 working days after drawing approval. Confirmed in writing.
