How do I calculate how much garnet I will need for my application?

Total garnet required for any waterjet cutting application is calculated by the OEM software. Orifice/nozzle configuration will determine the recommended abrasive flow rate per minute. Once abrasive flow is determined, flow rate can be multiplied by the total inches per minute to determine the required volume of garnet. The OEM software may produce a summary sheet to provide this data. Consult your waterjet OEM with any questions.

How do I remove spent garnet from my waterjet tank?

The BARTON Abrasive Removal Tool (BART) is a convenient and effective tool for removing spent garnet from your waterjet tank. BART complements any type of central abrasive removal system. BART can clean many areas of the waterjet tank that the central removal systems don’t effectively clean, and BART produces higher removal rates on an hourly basis. Learn more.

Can glass be cut on a waterjet?

Yes, glass can be cut on a waterjet. Depending on the thickness, glass may flex during cutting and therefore should be fully supported on a flat level surface. HYDROBLOC waterjet bricks are a good support and will reduce the chance of frosting on the bottom of the glass. We recommend ADIRONDACK 120 HPX for cutting glass as it minimizes micro-fracturing.

Can garnet be used to etch with a waterjet?

BARTON garnet abrasives can be used to etch using a waterjet. However not all waterjet equipment has the software required for etching. Check your users manual to determine if your model and software has etching capabilities.

How do I minimize the kerf loss?

The primary factors on kerf loss are nozzle diameter and orifice selection. Using a larger nozzle than needed will increase kerf loss. Orifice alignment will also affect kerf loss. Improper orifice alignment will cause the stream to bounce inside the nozzle and will decrease nozzle life and lead to additional kerf loss. If common line cutting can be utilized in the software it can reduce kerf loss. The TRIDENT cutting head will insure proper orifice alignment and help to reduce kerf loss.

How do I adjust my waterjet to use BARTON abrasives?

Any changes of waterjet grades or abrasives from different suppliers will require recalibration of the abrasive flow rate. Because particle size distributions (PSD) vary from supplier to supplier abrasive will flow at different rates. Once the abrasive flow rate has been calculated, the measured feed rate must be entered into the OEM software. Learn more.

HPX is often the higher priced waterjet abrasive. Why would I choose HPX garnet?

HPX is a hard rock garnet abrasive with an Adirondack advantage — the sharpest, hardest garnet crystals on Earth with a unique crystalline structure and durability. Named for the Adirondack Mountains where it is exclusively mined by BARTON, ADIRONDACK HPX is the sharpest, cleanest, fastest cutting and most precise waterjet cutting abrasive available. Learn more and contact our sales team for help selecting the best abrasive for your application.

Does BARTON offer a garnet recycling program?

Yes. BARTON offers a garnet recycling program, however there are some local and regional restrictions that limit the areas the program is available. Contact your regional sales manager to learn more.

Which waterjet machine do you recommend?

While BARTON has strong, supportive relationships with virtually every OEM, we do not recommend one waterjet machine supplier over another. We can assist you in making sure that you are aware of all of the OEMs and discuss what machine types they may offer.
