Although lenses made from Trivex material are formulated for processing with standard tooling and machinery, each manufacturer’s equipment responds differently. The instructional videos below provide video demonstrations and information on techniques for edging Trivex for optimal results.

General Guidelines for Edging Lenses Made From Trivex Material
- Edging equipment to have a vacuum system attached to remove sward and airborne particulate. This will minimize clogging of the edger.
- Use "other material, acrylic or polycarbonate cycle" settings for best results.
- Use counter rotation of part to edger wheel direction
- If you are not using the latest edging models, try edging dry. You can use water on the final rotation or cycle.
- Use "slow" wheel speed setting for optimum results.
- High-speed blade/cutters work well. Use polycarbonate settings.
- Consult edging manufacturer for adjusting head pressure if undue friction is occurring.
