Waterjet for glass cutting

Over view


Waterjet cutting  is a great method for cutting glass because it allows for contours and shapes that cannot be achieved with other cutting machines at a reasonable cost. From artistic tabletop inlays to detailed stained glass designs, mirrors, glass ornaments, replacement windows for antique cars, and more, there’s almost no glass cutting application that a waterjet cutting machine from Watex can’t tackle.Glass has a tendency to crack, so it is very important that the initial holes are produced with a reduced pressure of 7,200 PSI/500 bar to 11,600 PSI/800 bar. 

Subsequently, the pressure must be increased to a cutting speed that is cost-effective. And should open the Watex abrasive valve firstly then open the high pressure pump .For glass cutting ,our software have the feature can cut in the lower pressure then cutting a more high pressure in a quick speed guarantee the cutting quality and cost together .

Water jet cutting is always used to create artistic glass designs such as in detailing in stained glass, mirrors, ornaments of all sizes, glass awards, replacing windows in antique cars and many other practical applications. This versatility makes water jet  cutting especially useful and helpful .However while there are few limitations in what these tools can do, there are a few things to consider before using a water jet for glass cutting.

These required considerations are:

 •      The Quality of the Glass
 •      The Support of the Glass
       The Timing of Abrasive and Water Delivery
 •      Temperature
       The Design of the Glass Part
The quality of the glass is a very important starting point. A low quality or very thin glass is not ideal for water jet cutting, though it can be done extra care is required. Ideally, a thick, high quality glass would be the best choice for most projects. These high quality glasses are also far more durable than low quality which tend to be brittle and make the water jet cutting process more difficult.

Also it should be noted that tempered glass is impossible to cut. Tempered glass is created to be constantly under stress, so if an attempt to cut will made it remove this stress and will cause the glass to shatter. 

When glass is being cut by water jet, it's also important to consider how it is being supported while the cutting is occurring. An even support that is soft enough so the water jet doesn't bounce back as it hits it is ideal. Two common supporting pieces are Styrofoam or a solid sheet of plywood. These provide a good support, but most importantly, they must be level.
   
Water jet glass cutting uses an abrasive particle suspended within the pressurized water. When considering, it's important to regulate the timing of the water and abrasive. It's critical for the abrasive to hit the glass at the exact moment the water hits the glass. Water with no abrasive in it will cause the glass to simply break.
 

Some tips with regard to abrasive and water:

 •      Turn on the abrasive valve firstly then open the abrasive valve
 •      Use a scrap piece initially to test the flow rate.
 •      Cut at the edge of a piece of glass or from a previous hole.
 •      Start at a low pressure and turn up the pressure slowly.

Being aware of temperature changes is also important. Fluctuations from hot to cold  can cause glass to break easy. If your glass was hot and the water you were using to cut with was cold, this differencel may cause the glass to shatter. 

Lastly, consider the design. Ideally use long lead ins to protect from cracks. Should a crack occur early into the piercing of the glass, it is less likely to make it's way to the design if it has a long lead in. The more piercings in a design will result in a higher likelihood of it cracking. Minimizing the number of piercings is key, especially in very detailed designs.
 
In summary, considering the quality of your glass, the support you provide for the glass during the cutting, the timing of the abrasive and water, the temperature and the design. Taking these five items in consideration when doing a water jet  cutting glass project will result in a higher quality cut glass once complete.
