Glass Drilling
Glass Drilling
Precision Hole Processing for Flat & Shaped Glass
Overview
Our Saida Glass offer comprehensive glass drilling solutions ranging from small-scale sample production to high-precision industrial manufacturing. Our processes cover micro holes, large-diameter holes, round and shaped holes, and thick or thin glass, meeting the requirements of electronics, home appliances, optics, furniture, and architectural applications.
Our Glass Drilling Methods
1. Mechanical Drilling (Tungsten Carbide / Diamond Bits)
Mechanical drilling is the most widely used method for small-scale production and prototyping.
Process Principle
A high-speed rotating drill bit embedded with tungsten carbide or diamond abrasives grinds through the glass via abrasion rather than cutting.
Key Features
● Suitable for small-diameter holes
● Low cost and flexible setup
● Requires low rotation speed, light pressure, and continuous water cooling
2. Mechanical Drilling (Hollow Core Drill)
This method is designed specifically for large-diameter circular holes.
Process Principle
A hollow diamond-coated tubular drill grinds a circular path, leaving a solid glass core to be removed.
Key Features
● Ideal for large and deep holes
● High efficiency and stable hole geometry
● Requires rigid drilling equipment and sufficient coolant
3. Ultrasonic Drilling
Ultrasonic drilling is a high-precision industrial drilling technology used for stress-free machining.
Process Principle
A vibrating tool operating at ultrasonic frequency works with an abrasive slurry to erode the glass surface microscopically, reproducing the shape of the tool.
Key Features
● Extremely low mechanical stress
● Smooth hole walls and high dimensional accuracy
● Capable of complex and non-round hole shapes
4. Waterjet Drilling
Waterjet drilling provides unmatched flexibility for thick and large glass panels.
Process Principle
An ultra-high-pressure water stream mixed with abrasive particles penetrates the glass through micro-erosion.
Key Features
● Cold processing with no thermal stress
● Suitable for any glass thickness
● Excellent for large formats and complex geometries
5. Laser Drilling
Laser drilling represents the most advanced non-contact drilling technology.
Process Principle
A high-energy laser beam locally melts or vaporizes the glass material to form precise holes.
Key Features
● Extremely high precision and speed
● Fully automated processing
● Ideal for micro-holes
Limitations
Thermal effects may cause micro-cracks and require optimized parameters or post-treatment.
Double-Sided Drilling (Advanced Technique)
Double-sided drilling is not an independent drilling method, but an advanced technique applied to mechanical drilling using solid or hollow drill bits.
Process Principle
Drilling starts from the front side to approximately 60%–70% of the glass thickness
The glass is then flipped and precisely aligned
Drilling is completed from the opposite side until the holes meet
Advantages
● Effectively eliminates exit-side chipping
● Produces smooth, clean edges on both sides
● Particularly suitable for thick glass and high edge-quality requirements
Our Advantages
● Multiple drilling technologies available under one roof
● Controlled processes to minimize chipping and internal stress
● High edge-quality solutions including double-sided drilling
● Engineering support for customized hole structures and tight tolerances
