Overview of Waterjet Technology for CNC Glass Cutting

How Waterjet Technology Works

Waterjet technology is a high-pressure water cutting process utilized in CNC machinery. It involves the use of a high-pressure water stream, often mixed with abrasive materials, to cut and shape glass with extreme precision. The waterjet system uses a pump to deliver water at pressures ranging from 25,000 to 60,000 psi, while a nozzle focuses the stream to a width of 0.004 to 0.060 inches, depending on the requirement.

One of the most advanced waterjet systems available is the SANKEN waterjet CNC glass cutting machine. These machines are designed to deliver precise cuts with high repeatability and accuracy. The SANKEN waterjet system features the following specifications:

• Pressure: Up to 60,000 psi for optimal cutting performance
• Abrasive flow rate: Adjustable to suit the material being cut
• Cut width: 0.004 to 0.060 inches, depending on the material thickness
• Repeatability: 0.005 inches or better, ensuring consistent cuts
• Speed: High-speed cutting capabilities, capable of cutting through materials at high speeds
