Difficulties and Technological Breakthroughs in Glass Aspheric Machining
The core difficulty in glass aspheric machining lies in its complex geometry and extremely high precision requirements. The curvature change of the aspheric surface is complex, requiring high-precision equipment and technology to achieve precise shape control. Traditional cold machining methods are prone to shape deviations and surface defects when processing complex surfaces, making it difficult to meet the stringent requirements of optical performance. In addition, while single-point diamond turning machines perform well in the processing of certain materials, they can easily lead to a decline in surface quality when processing glass, failing to meet the needs of high-end optical applications.
These technical challenges have made glass aspheric machining a field requiring highly specialized expertise and advanced equipment. To this end, relying on optical technology, glass aspheric machining is taken as the core technological breakthrough direction. Through independent research and development and the introduction of internationally leading equipment (such as the Satisloh SPM-200 precision grinding machine) and innovative process technologies (such as magnetorheological polishing), problems such as shape accuracy, surface quality, and material damage have been successfully solved, providing customers with high-precision, high-quality processing solutions.
