Abstract
Needs of the digital camera and the mobile phone with camera increase, and the necessity of a high NA asphere glass lens has risen in recent years. Such glass lens is molded by using ceramic mold of Tungsten carbide, and the ultra–precision aspherical grinding is important. Then, the cross and parallel mode grinding machine for the aspherical mold grinding was developed, and the grinding characteristics of was evaluated.
