Glass is one of the most versatile materials used in various industries, ranging from architecture to electronics and art. It is formed by cooling molten silica rapidly, resulting in a transparent, brittle material. Despite its beauty and versatility, cutting glass is a challenging task.
Its brittle nature means it can easily crack, chip, or shatter under stress, making traditional cutting methods less effective and prone to damage.
This is where water jet cutting machines shine. They provide a modern, precise, and efficient solution for cutting glass without compromising its structural integrity.
In this blog, we’ll explore how water jet cutting machines handle glass, their benefits, and how to choose the right service for your needs.
Can You Cut Glass With a Water Jet Cutter?
Yes, you can cut glass with a water jet cutter. In fact, water jet cutting is one of the most efficient and reliable methods for cutting glass, whether it’s for industrial purposes or intricate artistic designs.
Traditional methods like scoring and breaking glass often result in micro-cracks, uneven edges, or complete failure of the material. In contrast, water jet cutting uses high-pressure water mixed with abrasive materials to create a clean and smooth cut. This process minimizes the risk of cracking or damaging the glass.
With the ability to cut through various types of glass regardless of thickness, water jet cutters have become an indispensable tool for industries such as construction, automotive, and manufacturing.
How Waterjet Cutting Works for Glass?
Water jet cutting for glass involves using a stream of highly pressurized water combined with abrasives like garnet. This mixture allows the water jet cutter to carve through the glass with incredible precision and minimal stress. Let’s break down how the process works:
- High-Pressure Water Stream: The cutting machine generates a high-pressure water stream—ranging from 50,000 to 90,000 PSI. This water is directed through a narrow nozzle at supersonic speeds.
- Abrasive Materials in Action: Abrasive materials, like garnet, are added to the water stream to enhance its cutting ability. The abrasives act like tiny cutting tools, grinding through the glass with precision.
- Adjustable Pressure for Thickness: The pressure used during water jet cutting can be adjusted based on the thickness and type of glass being cut. Thicker glass requires higher pressure and more abrasive material, while thinner or delicate glass may need lower pressure to prevent cracking.
What Are the Types of Glass Suitable for Waterjet Cutting?
Water jet cutting is highly versatile and can handle a wide range of glass types. However, not all glass is suitable for this method. Let’s explore which ones work best:
Types of Glass That Can Be Cut with Waterjet
- Annealed Glass: This is the most basic type of glass, often used in windows, doors, and tabletops. Since annealed glass doesn’t have internal stress, it’s one of the easiest to cut with water jets.
- Laminated Glass: Comprising two or more layers of glass bonded with an interlayer, laminated glass can be cut effectively. The water jet’s precision ensures clean cuts through the layers while maintaining the laminate’s integrity.
- Stained or Decorative Glass: Commonly used in art and interior design, stained glass can be intricately shaped with water jets to create unique patterns and designs.
- Frosted Glass and Mirrors: Water jet cutting preserves the finish on frosted glass and mirrors, making it ideal for applications requiring smooth, aesthetic results.
- Bulletproof and Specialty Glass (With Limitations): Thick, high-strength glass, like bulletproof glass, can be cut, but it requires advanced machinery, higher pressure, and more abrasive material, making it time-consuming.
Types of Glass That Can’t Be Cut with Waterjet
- Fully Tempered Glass Without Perforations: Tempered glass is under immense internal stress. Cutting it directly can lead to shattering, as the stress is unevenly released.
- Overly Thick Glass: While water jets can cut thick materials, extremely thick glass may require multiple passes, leading to time and material inefficiencies.
