LIGHTING GLASS · PRECISION OPTICAL GLASS PROCESSING

Precision Optical Glass Processing & Custom Fabrication

From Glass Substrates to High-Precision Components

Guangzhou Lighting Glass Co., Ltd. specializes in precision cold processing of optical and technical glass components. For optical communications, semiconductors, MEMS, laser optics and industrial equipment, we provide custom cutting, precision CNC machining, drilling, grinding, double-side polishing, edge finishing, cleaning and quality inspection.

We plan the process around customer drawings, material properties, dimensional tolerances and surface requirements, with attention to TTV, parallelism, surface roughness, edge chipping and cleanliness. We support prototypes, pilot runs and volume production of precision glass parts ready for downstream assembly.

Precision glass clean processing workshop

Precision Glass Processing

The process route is derived backwards from the final acceptance requirements

Dimensions, edges, surfaces, cleanliness and packaging are not separate issues. We sequence the operations around the finished-part requirements rather than offering isolated machine operations.

Quality Control

Turning "acceptable" into explicit dimensional and surface acceptance items

From incoming material and cut edges to polished surfaces and post-cleaning cleanliness, we define measurable, recordable inspection logic for each project.
