Progressive Spectacle Lens Mold
Single point diamond turning utilizing the Precitech Nanoform 700 Ultra. The mold is used to make progressive eyeglasses. The surface is a free-form shape that is cut by a turning process at 105 RPM using coordinated motion of the X, Z and C machine axis. Because of the ultra-precision capability of the Precitech Nanoform 700 Ultra the surface finish of the mold, right off the machine, is less than 1.5 nm Ra
