Advantages of CNC Glass Machining
CNC machining ensures each glass component is produced with micron-level accuracy, maintaining consistent quality even in high-volume production.
We can easily handle intricate shapes, cutouts, tapered holes, and multi-level structures — ideal for advanced optical and microelectronic designs.
Automated CNC processes reduce lead time, minimize errors, and boost overall productivity — from rapid prototyping to full-scale manufacturing.
Our CNC systems support diverse optical materials including borosilicate, quartz, aluminosilicate, fused silica, and Corning® specialty glasses.
we offer a comprehensive range of processing options
CNC Glass Cutting and Profiling
Using multi-axis CNC equipment, we perform straight cuts, complex profiles, curves, and custom geometries with extremely tight tolerances. From simple squares to intricate optical components, every cut is engineered for precision.
CNC Glass Drilling and Slotting
We provide fine-pitch hole drilling, slotting, and grooving services with micron-level control. Whether it’s microholes for optical assemblies or slots for semiconductor devices, our CNC drilling solutions ensure smooth edges and minimal stress on the glass structur
Glass Wafer Dicing and Machining
We offer precision glass wafer machining for 2″, 4″, 6″, 8″, and 12″ sizes, supporting applications such as:
- CMOS and CCD sensor packaging
- MEMS devices
- IC substrates
- Optical communication modules
- AI and AR display technologies
Through CNC-controlled wafer dicing, we maintain dimensional accuracy and surface quality, meeting stringent industry standards.
