16 December 1976 Grinding Glass Aspheres Using A Pantograph
Author Affiliations +
The pantograph incorporates a diamond wheel spindle on a precision air bearing running with great smoothness and works at a ratio of 6-1 following a master cam which was made by tape control. The glass is held to the work spindle by vacuum. Roughing cuts are made with metal bond diamond wheels and finishing cuts with resin bond wheels. Surface accuracies of ±0.0001" per inch are obtainable along with a 5 micro inch surface roughness.
