Why Garnet is the Preferred Abrasive Material for Water Jet Cutting Machines?

Abrasive materials can be lined up as one of the vital components of any water jet machine cutting process. When you add abrasive substances to the water itself, particularly garnet particles, that is the time that you can intensify its cutting power and thus can be used for cutting tough materials like metals. Water jet machines that are not using abrasive materials are usually utilized for cutting “softer” materials instead such as rubber and foam.

As one can imagine, the type of abrasive material that can be used for this purpose is paramount to determining the level of success a waterjet-based machining process will have. Abrasive garnet materials offer waterjet machine operators a rigid and reliable substance that will form sharp edges when fractured. This measure paves the way for it to have that superior cutting power.

Professionals before have tried and tested a sundry of materials to identify the most effective abrasive substances that can be used for water jet machine cutting purposes. But garnet abrasive stood out among others and, thus, became the abrasive material of choice by the industry itself.

What makes Garnet Ideal for Waterjet Cutting Machines?

Industry insiders commented on this and asserted that garnet, as an abrasive material for waterjet system of cutting, offers users the right combination of density, durability and particle shape that maximizes the cutting power of standard waterjet systems.

Above that, garnet is qualified as an inert type of chemical. What does this signify then? It means to say that it is not likely to have a poor reaction with whatever materials you are trying to cut.

Choosing the Correct Garnet

When it comes to cutting, not all garnet is good for this purpose. It‘s because you will find some garnet solutions out there as far more effective compared to others — despite the fact that these minerals have an almost identical chemical makeup.

It is estimated that around 70% of the operating costs involving waterjet machining would account for abrasive. With respect to this, the kind of garnet abrasive material you will decide to utilize for any particular project will have a significant amount of impact on how successful the project will be as well as the economic side of things, too.

Garnet can be found in a wide spectrum of grit sizes, each designed and intended for different results. With respect to the hardness level of the machining material you are working on, the finish can come out rough or smooth.

In most cases, fabricating firms will need to make use of finer grits on projects that require smoother and higher edge quality. As for the large-sized grits, they are most effective when utilized on projects that necessitate faster cutting.

Usually, what happens when fabricating firms purchase garnet abrasive material, they’d receive it on their end in a sand-type form. It will be run first via a screen initially. This measure will allow them to obtain first the exact sizing they require.

They also come in a spectrum of “mesh” sizes, and fabricating firms would be choosing mesh sizes with regard to the material they are working on to cut. Generally speaking, mesh sizes can be found in the range of 50 to 200. This would be indicating the size of the garnet abrasive substance in “microns”.

Using Garnet for Your Abrasive Waterjet Cutting Machine

Standing next to diamond in terms of hardness and other similar minerals, garnet made it to the top choices for the majority of abrasive waterjet projects. Depending on the hardness, sharpness, shape, and purity, some garnet materials would be better for cutting works. And yet with regard to their sharp edges, durability and low chemical input, they are ideal for use to cut almost any material.
