Precision Edge Grinding and Polishing Technology of K9 Optical Glass

K9 (BK7) optical glass is widely used in precision optical and laser systems, yet its hard brittle nature makes high-precision edge grinding prone to chipping, microcracks and severe subsurface damage. Traditional processing struggles to balance efficiency, surface quality and dimensional accuracy, failing to meet ultra-smooth and high-precision optical requirements. This paper presents a standardized edge grinding and polishing solution adopting Moresuperhard D150 series resin diamond wheels with 400#–1200# graded grain sizes. By utilizing ductile regime grinding and optimized process parameters, the method effectively suppresses edge defects, thermal deformation and subsurface damage. It enables stable mass production of K9 glass edges with Ra＜0.02μm roughness and λ/10 surface accuracy, providing a reliable high-yield processing reference for optical cold machining.

Application Value of Diamond Cutting Blades in Industrial Ceramic Processing

Industrial ceramics are widely used in semiconductors, new energy, aerospace, and medical precision manufacturing due to their high hardness, low thermal conductivity, and excellent chemical stability. However, their extreme brittleness and high microhardness create significant cutting and finishing challenges. Traditional cutting tools easily cause edge chipping, subsurface microcracks, low precision, and high scrap rates. Diamond cutting blades have become the mainstream processing solution for high-performance industrial ceramics because of their superhard abrasive properties, stable mechanical structure, and adaptable processing performance. This article systematically summarizes their technical advantages, efficiency improvements, cost benefits, and scenario-based application values for industrial ceramic machining.
