Double-Sided Lapping for Acrylic Components

The customer provides an acrylic triangle with a thickness of +/- 0.040” and needed the thickness of the part within 0.001” of nominal and a surface finish that measures 24 Ra or better.

In addition, the customer hoped the finishing process would not introduce visual variations in the color of the part.
Utilizing one of our double-sided machines and free abrasive machining, we delivered parts with a thickness of +/- 0.001”, flatness within +/- 0.002”, parallelism within +/- 0.001”, and surface finish that measures 24 Ra or better.

In addition, the customer was very pleased with our processing methods as there was no discoloration of the parts.
