At LIGHING GLASS, we specialize in providing high-precision glass processing solutions for various industries, particularly in glass polishing, grinding, and thinning. With deep technical expertise and extensive industry experience, we ensure that each glass product meets strict requirements for precision, flatness, thickness, and surface quality. Whether it’s optical components, electronic devices, medical instruments, or display glass, our services guarantee exceptional performance and quality.

1. Precision Glass Grinding

Glass grinding is the core step in the entire processing workflow, directly affecting the flatness and smoothness of the glass surface. Our double-sided grinding technology uses high-precision equipment to evenly remove material from both surfaces of the glass, ensuring optimal flatness, parallelism, and thickness tolerance.

★Double-sided grinding: This is our primary method for processing. By grinding both sides of the glass simultaneously, we achieve higher precision and consistency. This technique is especially suited for high-precision processing of thin glass substrates, with thicknesses as thin as 100μm. Double-sided grinding provides excellent flatness, parallelism, and thickness control, making it ideal for high-end applications that require fine surface finishes and strict tolerances.

2. Glass Polishing

Glass polishing is more than just removing surface roughness; it is a crucial step in achieving a perfect, flawless finish. We use the latest single-sided and double-sided polishing technologies, utilizing fine abrasives, specialized polishing cloths, and liquid abrasives to ensure a mirror-like smooth surface on each glass piece.

★Single-sided polishing: This method is suitable for glass components that require polishing on one side only or have different surface finish requirements. Using precise polishing machines, we apply abrasives to one side of the glass, ensuring a perfect finish while protecting the other side from damage.

★Double-sided polishing: This technique is ideal for applications where both sides of the glass must have identical high-precision polished surfaces. Using fine polishing cloths and liquid abrasives, both sides of the glass are evenly processed to achieve an exceptionally smooth surface while maintaining parallelism and flatness. Double-sided polishing is particularly suitable for optical, semiconductor, and other applications requiring extreme surface accuracy.

3. Glass Thinning: Precise Control of Glass Thickness to Meet Ultra-thin Requirements

For certain applications, especially in the optical and semiconductor industries, glass thickness requirements are extremely strict, often requiring glass to be thinned to micrometer levels. We employ advanced thinning technologies, utilizing double-sided or single-sided grinding processes to precisely control glass thickness, ensuring minimal tolerance and consistency.

★Thinning process: During the glass manufacturing process, we use double-sided grinding technology to remove excess material, precisely controlling the thickness of each part. Whether it’s glass as thin as 100μm or applications with strict requirements for thickness variation (TTV), we guarantee consistent thickness and surface quality.
