Glass is widely used across various industries, and with the advancement of technology, the demands for glass drilling have increased significantly. People are not only looking for faster processing speeds and minimal chipping but also for the ability to create various shapes of holes. Currently, the most common drilling methods available in the market are water jet drilling machine , mechanical drilling machine , and laser glass drilling machine .In the different methods of glass drilling, laser glass drilling machine , water jet drilling, and mechanical drilling each have their own characteristics and suitable applications. Below is a comparison of these three methods:
1. Laser glass drilling machine
Principle: Laser focuses to generate high temperatures, rapidly heating the glass surface, which leads to localized thermal stress fractures that create holes.Advantages:
- High Speed: Laser drilling can achieve speeds of 60 to 120 m/min, making it suitable for large-scale production.
- High Precision: It can process hole diameters as small as 0.3 mm and as large as 200 mm, with clean and uniform hole shapes that have no taper.
- Non-contact Processing: This method avoids physical contact found in traditional methods, reducing the risk of glass breakage and cracking.
- Versatile Shape Capability: It can create various shapes of holes, including round, square, and irregular shapes.
- Minimal Chipping: The chipping value is controlled within 600 microns, eliminating the need for secondary processing.
- No Pollution: It does not require water treatment, making it energy-efficient and environmentally friendly.
Disadvantages:
- High Technical Requirements: Operation and maintenance require specialized knowledge.
2. Water Jet Drilling (High-Pressure Water Jet Drilling)
Principle: This method uses high-pressure water jets (typically between 750 to 1000 MPa) to cut through the glass material.Advantages:
- Good Cooling Effect: Water cooling during the drilling process minimizes thermal impact.
- No Dust Pollution: The use of water prevents dust generation during construction.
- Suitable for Thick Materials: It can effectively process thicker glass materials.
Disadvantages:
- Lower Efficiency: Compared to laser drilling, it operates at a slower speed and has higher processing costs.
- Potential Stress Damage: Contact-based processing may cause surface scratches or edge chipping.
3. Mechanical Drilling (Using Hard Drill Bits)
Principle: This method employs drill bits made from ultra-hard materials to mechanically cut through the glass by rotation and pressure.Advantages:
- Widespread Equipment Availability: Mechanical drilling equipment is relatively mature and easy to obtain.
- Broad Adaptability: It is suitable for various thicknesses and types of glass.
Disadvantages:
- Significant Thermal Impact: Heat generation during processing necessitates cooling fluids to prevent glass breakage.
- Lower Processing Precision: Typically cannot achieve the precision of laser drilling and may result in burrs and cracks.
If you are looking for an efficient, energy-saving glass drilling machine, laser glass drilling machine is your best choice. More importantly, laser glass drilling machine not only performs glass drilling function but also offers functions such as sandblasting and paint removal. This means you can invest in one piece of equipment that fulfills multiple processing needs, significantly reducing procurement costs.For more information, please contact:
