Glass Cutting

Overview of Modern Glass Cutting Techniques

Glass cutting is the essential first step in transforming raw sheets into usable pieces. The right method makes all the difference in efficiency, precision, and final quality. Here’s a look at the three most common techniques used in the industry today.

Comparison of Three Main Glass Cutting Processes

1. Diamond Wheel Cutting

This is the classic, go-to method for most standard jobs. A computer-guided machine uses a super-hard diamond wheel to score a clean line on the glass surface, which is then cleanly snapped apart. It's the most cost-effective choice for high-volume production.

• Best For:
Straight lines, large simple curves, and standard shapes like windows and table tops.
• Max Sheet Size:
Up to 2440*3660mm.
• Thickness Range:
0.33mm to 19mm.
• Tolerance:
±0.3mm.

2. Laser Cutting

Laser cutting takes a high-tech, non-contact approach. A focused beam of light heats and melts the glass along a digitally precise path, vaporizing a tiny line of material.

• Best For:
Extremely complex, intricate designs and very thin or delicate glass. It leaves a smooth, fire-polished edge.
• Thickness Range:
0.33mm to 10mm (ideal for thin substrates).
• Tolerance:
±0.1mm.

3. Waterjet Cutting

Think of this as the versatile powerhouse. It uses an ultra-high-pressure stream of water mixed with abrasive sand to literally erode through the glass. Since it’s a cold process, it prevents heat-related stress.

• Best For:
The most complex shapes, thick laminated glass, and materials that can’t handle thermal stress.
• Max Sheet Size:
1780*1500mm.
• Thickness Range:
2mm to 15mm.
• Tolerance:
±0.2mm.
