Can I get next day delivery of waterjet parts?

Waterjet parts orders received by 3PM Eastern Time, Monday – Friday typically ship the same day, and you can request next day delivery service. FOB point is Petersburg, VA or Fullerton, CA.

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.

Are garnet abrasives safe?

BARTON garnet is one of the safest abrasives on the market. Our garnet is a naturally occurring mineral containing zero residual hazardous materials with little to no risk of exposure to quartz and/or heavy metals. BARTON garnet abrasives are low dusting and are environmentally friendly.

Are BARTON garnet abrasives safe to use?

BARTON garnet abrasives are considered non-hazardous. Please see the safety data sheet (SDS) for product properties and safe handling and storing guidelines. Safety data sheets can be downloaded from our library.

Are BARTON garnet abrasives hazardous?

BARTON garnet abrasives are considered non-hazardous. Please see the safety data sheet (SDS) for product properties and safe handling and storing guidelines. Safety data sheets can be downloaded from our library.

How do I find the Safety Data Sheet (SDS) for BARTON abrasives?

Safety Data Sheets (SDS) for BARTON abrasives can be downloaded from our library.

Do BARTON garnet abrasives contain beryllium?

Test data demonstrates that beryllium levels in BARTON garnet are non-detectable; below laboratory detection levels. Learn more about OSHA’S beryllium standard.

Do BARTON abrasives contain respirable free quartz (silica)?

Worker safety is always a priority at BARTON. We regularly test for respirable free quartz levels in our abrasives to ensure concentrations are below 0.1%. Safety data sheets can be downloaded from our library.

What is the difference between total quartz and respirable quartz as listed in the SDS?

Quartz, or silicon dioxide, is a commonly found mineral. The size of the quartz particle determines the inhalation hazard. For example, quartz crystals can grow to be quite large and therefore, do not pose an inhalation hazard. On the SDS for BARTON abrasives, this is described as “Total Quartz”. Worker safety organizations OSHA, NIOSH  and ACGIH agree that it is the respirable crystalline silica fraction that poses the true inhalation health hazard. BARTON has confirmed through an independent Hazard Classification Study that the respirable quartz fraction contained within our garnet abrasives is less than 0.1%.

Do I need to train my employees on the proper handling of garnet abrasives?

Yes. Although BARTON garnet abrasives are considered non-hazardous during normal use and routine clean-up activities, your employees need to understand the proper safe handling measures and work practices when working with any and all materials.

Why is housekeeping so important when using garnet abrasives?

As with any material, housekeeping is paramount to reduce potential employee exposures to any type of dust. During our Hazard Classification Study, we did find a relationship between extremely poor housekeeping conditions and the ability to detect respirable quartz. Although these exposures did not exceed the OSHA PEL, the levels were detectable by NIOSH Method 7500 when housekeeping was poor. As a reminder, as with all dust, wet-methods and/or vacuuming of dusts is the best way to prevent the suspension of dust particles in the air.

What are the OSHA regulations as they relate to BARTON abrasive product offerings?

BARTON abrasive products are subject to OSHA Hazard Communication regulations (29CFR 1910.1200) and are compliant with Global Harmonized System (GHS) standards. Product Safety Data Sheets (SDS) include information such as the properties of the abrasive; the physical, health, and environmental health hazards; protective measures; and safety precautions for handling, storing, and transporting the abrasive. Safety data sheets can be downloaded from our library.

How do I dispose of spent garnet?

Prior to disposing of spent garnet, please review applicable local, state and federal regulations. Although BARTON abrasives are classified as non-hazardous, it is the responsibility of the waste generator to ensure spent materials are disposed in accordance with applicable solid waste regulations. Depending on the waste generation process, additional testing (i.e. Toxicity Characteristic Leaching Procedure (TCLP)) may be required in order accurately assess the proper waste classification.

Why do some other supplier’s garnet abrasive safety data sheets (SDS) say “Danger: May Cause Cancer” and some say nothing at all about quartz?

BARTON has completed the due diligence regarding the proper hazard classification for our garnet abrasives and have had a third-party expert lead a scientific Hazard Classification Study. Not all garnet abrasives are the same nor have all garnet abrasives suppliers undertaken the same rigorous assessment to accurately classify the hazards with their products as we have. We encourage you to develop a relationship with all of your suppliers so that you can be in the best position to ensure the health and safety of your employees.

What industrial hygiene method did you use to assess exposures during the Hazard Classification Study?

We followed NIOSH Method 7500 and used accredited laboratories for determining the crystalline silica concentrations in BARTON garnet abrasives.

What is the shelf life of garnet abrasives? Is there an expiration date?

BARTON garnet abrasives are naturally occurring minerals that do not contain chemical additives. There are no product expiration dates. However, proper storage methods need to be followed. Store abrasives in a cool dry place; preferably indoors. Keep container/package tightly closed and in a well-ventilated place without large temperature swings to prevent condensation. Abrasives stored in FIBC’s – flexible intermediate bulk containers, commonly called bulk bags, must be kept out of direct sunlight as UV light can deteriorate FIBC’s that are intended to be single use bags. Learn more about FIBC safe handling guidelines.

What are the advantages of using an abrasive bulk hopper and bulk bags?

Bulk bags provide the advantage of loading the abrasive hopper in one shot as compared to 55 LBS at a time with paper bags. The risk of paper bag contamination is also eliminated. Proper handling of bulk bags may also reduce the possibility of injuries related to handling paper bags. FIBC guidelines must be followed when handling bulk bags, and the bulk hopper must be installed properly. Installation guidelines for the BARTON abrasive hopper.

Should I pre-screen my abrasive? Why?

Our manufacturing processes are built on strict, comprehensive quality control standards to ensure the proper particle size distribution (PSD) and abrasive quality. However, when opening paper bags, fibers or contaminants could be introduced into the abrasive. Therefore, we recommend screening the garnet to help capture these particles.

What is the proper way to store abrasives?
