GMA Waterjet Garnet

GMA Garnet™ abrasive is extensively used in all renowned waterjet cutting machines around the world.

The highest purity garnet and highly accurate sizing of grains are produced using the world’s best processing methods. This ensures that there are no dust or ineffective fine grains that can restrict garnet free flow – oversized grains may create a blockage in the focusing tube.

A steady flow of garnet abrasives to the focusing tube that is free from blockages allows uninterrupted production without downtime resulting in optimum efficiency and lowest production costs.

In addition, millions of years of weathering the hard and tough sub-angular garnet grains provide the perfect balance between cutting speed and edge quality. High quality alluvial garnet does not contain any fracture lines that weaken the grain inherent with crushed garnet.

Equipment wear and tear in particular, the cutting head and focusing tube are also reduced. This translates to direct cost-savings and longer service life.

GMA Garnet™ consists of totally natural Almandine garnet known for its superior hardness and abrasive ability. It is free of any heavy metals or toxic compounds and meets all Occupational Health and Safety regulations and provides a perfect balance of grain shape (sub angular) size and density.
