Professional Glass Hole Drilling
Drilling glass requires specialized machinery and stable techniques. Weiman Tech specializes in precision cover glass drilling, ensure each hole meets exact dimensional specs with clean interior walls for easy assembly. We serve industries ranging from consumer electronics and healthcare to smart home and industrial automation, with consistent quality you can rely on.
Our Glass Drilling Capabilities
We offer two advanced drilling methods: CNC drilling and laser drilling. Each delivers distinct advantages in precision, process control, and application range. Whether you need tiny micro-holes or larger openings, we tailor our approach to meet specific project requirements. These techniques ensure reliable, high-quality results for cover glass used across electronics, medical, automotive, and industrial sectors.
CNC Drilling
CNC glass drilling uses CNC machines with diamond-tipped bits or other hard tooling to mechanically create holes in glass.
Characteristics:
- Handles larger holes, typically from a few millimeters to tens of millimeters in diameter.
- Supports through holes, blind holes, and countersunk designs.
- Works with a broad thickness range, from 0.5 mm up to 5 mm or more.
- Requires edge polishing after drilling to reduce micro-cracks.
Advantages:
- High precision, with hole diameter tolerances as tight as ±0.05 mm.
- Cost-efficient for medium to large production runs.
Laser hole drilling
Laser-Based Micro-Drilling for Glass Laser drilling applies a highly focused beam to selectively remove glass layer by layer, using heat or light-induced chemical reactions.
Typical specs:
Hole sizes:
- commonly 20–500 µm, with high repeatability.
- Stress-free process ideal for fragile or pre-stressed glass types.
- Edge quality is significantly cleaner, often skipping the polishing step.
Why choose it:
- Achieves extremely tight tolerances for micro-components and high-density layouts.
- Excellent choice for chemically strengthened glass, as it avoids introducing new surface flaws.
Our Advantage in Glass Drilling
What sets us apart is our dual-technology approach: CNC for robust, larger openings and laser for fine, intricate micro-holes. This flexibility allows us to match the ideal process to each project. Backed by rigorous quality assurance and responsive support, we provide cover glass solutions that perform reliably in the field.
Precision You Can Rely On
Our drilling processes deliver tolerances as tight as ±0.05 mm on hole diameters. This level of accuracy ensures every opening matches your design precisely—whether for sensors, cameras, or connectors, so your cover glass fits and functions flawlessly.
±0.05 mm Tolerance – Guaranteed
Precision is non-negotiable. Our glass drilling holds hole diameters to ±0.05 mm accuracy, ensuring every opening aligns perfectly with your component layout. You get repeatable, dependable results that meet the tightest design requirements.
Thin Glass Specialists
Our drilling techniques are fine-tuned for glass from 0.5 mm up to 5 mm thick. Whether ultra-slim or moderately thick, we ensure clean cuts, minimal stress, and dependable performance—tailored to your exact material specifications.
Repeatable Precision, Every Time
Our drilling systems are calibrated for repeatability—holding tight tolerances across massive production runs. This means fewer surprises, smoother assembly, and consistent product performance. We don't just meet specs; we deliver them consistently, order after order.
Quality-Driven Glass Drilling
We prioritize durability through precise process control. By reducing micro-cracks and relieving internal stress, our methods produce stronger, more resilient panels. Every piece undergoes thorough quality checks to meet your performance standards.
Complex Patterns Made Simple
From simple openings to elaborate hole arrays, we support a wide variety of geometries and depths. Through holes, blind cavities, stepped or countersunk designs—we tailor every feature to your application, with precision and consistency across each panel.
Prototype to Production – One Partner
We support every stage of your product lifecycle. Start with low-volume prototyping to validate your design, then scale seamlessly into high-volume runs. Same rigorous quality, same precision—just the right quantity for your current needs.
