What are polished edges?
When we cut an acrylic sheet to size, the saw blade/router toolbit produces a matte finish on the edges of the panel. We use a technique called diamond polishing to polish the edges to a bright, smooth and glossy finish.
Our diamond edge-polishing machine polishes the edge of acrylic by running a rotating, diamond tipped wheel along the edge of the material.
You can read more about the techniques used to polish Perspex® in our blog post, The Ultimate Guide to Polishing Perspex®.
