Why High Precision Glass Drilling Technology is Crucial in Modern Automatic Glass Processing

What is High Precision Glass Drilling Technology

Definition of High Precision Glass Drilling

High precision glass drilling refers to the ability to create holes in glass with exact diameters, minimal deviation in positioning, and exceptional edge quality. It emphasises two main aspects: hole diameter precision and positioning tolerance, as well as edge quality with controlled chipping.

The positioning accuracy of drilling machines is tested using professional equipment, ensuring tight tolerance control, which is crucial in sectors such as electronics and automotive glass. Chipping control is achieved through optimised drilling speeds and specialised drill bits. For instance, advantages of the new type of glass drill include sharpness, durability, wear resistance, small edge chipping, high efficiency, and fast speed.

Key Technological Standards for High Precision Drilling

Achieving such precision requires advanced standards including:

• CNC Positioning Accuracy: Rack and guide rail drive the precision of machine head movement control, ensuring minimal deviation during operation.
• Spindle Speed and Feed Control: High-speed spindles with rotation speeds up to 12,000 rpm allow for precise drilling, ensuring minimal glass breakage and enhancing overall drilling accuracy.
• Cooling and Lubrication Systems: The oil circuit automatically pumps oil, which can be filled regularly and quantitatively to ensure the lubrication of each component, which prolongs machine life and maintains performance.

From Manual to CNC: The Development of Glass Drilling Technology

Limitations of Traditional Manual Glass Drilling

Traditional manual glass drilling machines have several limitations:

• High Breakage Rate: Manual pressure inconsistencies often lead to cracks or complete breakage.
• Unstable Hole Quality: Hole drawing and glass moving are both manual operations, resulting in variable quality.
• High Labour Intensity: Operators are required to perform multiple tasks manually, increasing fatigue and reducing throughput.

Advantages of CNC Glass Drilling Technology

CNC-driven systems offer multiple advantages for glass drilling technology:

• Consistent Precision: Equipped with a numerical control system, it can achieve high-precision automated drilling.
• Automated Tool Control: The system enables automatic tool changes, supporting a variety of tool holder specifications. This allows for the installation of multiple drill bits with different diameters simultaneously, optimizing efficiency and reducing downtime during the drilling process.
• Suitable for Both Mass and Custom Production: Some machines can be used standalone or connected with edging machines, cleaning machines, etc., to form an automated production line.

How Automatic Glass Processing Enhances Drilling Quality and Efficiency

What is Automatic Glass Processing?

Automatic glass processing is a comprehensive workflow that integrates:

• Drilling, Milling, and Polishing: A seamless process combining drilling, milling, and polishing operations to enhance efficiency and precision in glass processing.
• Automatic Glass Transportation Systems: Place the glass on the roller of the input table for feeding. When the switch detects the glass, the suction cup will suck on the glass, and the glass will begin to move.
• Barcode Scanning and ERP Integration: Can read information through online barcode and automatically divide/drill holes; Can be integrated with ERP, online drawing and navigation.
