How to Prevent Fogging on the Back of Water Jet Cut Parts

Sometimes when you are water jet cutting parts, you will notice a foggy haze on the back of the finished parts.  Fortunately, this is very easy to prevent.

To prevent foggy bottoms on your water jet cut parts, simply place your work piece on a sheet of inexpensive sacrificial material.  Many shops use corrugated PVC sheets.  Plywood also will do the trick.

Tips for Water Jet Cutting Glass

• Reduce the risk of chipping by using a low-pressure pierce of approximately 10,000 psi.
• Reduce low-pressure piercing time from two minutes to 10-15 seconds (depending on thickness) by cutting a tiny circle rather than leaving the jet fixed on one spot.
• 120 grit garnet will produce the best edge quality. If speed is your priority and chipping not a concern, use 80 grit garnet
• Cut at 75,000 psi to increase cut speed by 50-75% and improve edge quality.
• Support glass on a sheet of 3/16” corrugated PVC rather than directly on the metal slats. This reduces the risk of chipping and fogging.
• If your projects require you to frequently raise and lower pressure, install a patented Jet Edge Dual Pressure Valve to save time and prolong water jet pump component life.
• Tempered glass cannot be cut with waterjet.
