Sapphire Waterjet Orifices: Uses and Advantages

In the processing and manufacturing industry, abrasive water jet cutting is a method for precise and quick cutting of several hard materials. Complex and highly detailed shapes can easily be cut using a waterjet cutter. The water jet is shot through the aperture and enters the mixing chamber, which uses vacuum to introduce garnet sand into the water flow.

Although Waterjets are multi-functional and powerful cutting tools, the core of these machines is their aperture – a small nozzle-water made of synthetic sapphire, ruby or diamonds. The sapphire waterjet orifice is responsible for focusing the water flow, allowing smoother, cleaner cutting. Although the diamond orifices last longer, they are also the most expensive, which allows Ruby or Sapphire to be more attractive in some cases.

Sapphire and Ruby Waterjet Orifices

Many do not realize that Ruby and Sapphire waterjet orifices actually use the same basic material: synthetic corundum. The only difference is the chromium added to provide their red pigment to Ruby, and the fact that each type of manufacturing geometric shapes can vary. Corundum is widely used in a variety of applications due to its extreme hardness and easy reproduction. Five times harder than carbides and ranked 9. 0 On the Mohs hardness scale, the corundum is high temperature resistant, chemical resistant, and durable. Rubies can sometimes withstand more abuse than sapphire before failure. Ruby can also produce a more powerful vacuum than sapphire. On the other hand, sapphire uses “sharp-edge technology” to generate longer, smooth, coherent stream.

 

When to Use Ruby and Sapphire?

Unlike many orifice materials in the past, Ruby and SAPPHIRE can stand up to extreme environments without significant corrosion. Unfortunately, Ruby and Sapphire can be easily influenced by the minor impact of debris in the high pressure system, which may destroy their integrity. Ruby and sapphire orifices often cost far below diamond ones, and they can only last to 0-40 cutting hours, and compared to hundreds of hours from the diamond.

 

However, if the manufacturer needs to change the aperture combination, sapphire or ruby may pose less risks. Often changing the nozzle not only increase the possibility of the fragmentation, but also the possibility of damaging the aperture, and the orifice might be lost. Although a lost ruby or sapphire worth $20 may be frustrating, it is not as disastrous like losing diamonds, worth hundreds of dollars.

So, sapphire waterjet orifices, as you can see are extremely hard and durable and resistant to chemicals and high temperature. So, it’s easy to see why this material is hugely preferred in the construction of waterjet orifices. Their hardness and chemical resistance make them an ideal choice for orifices where water is forced out at pressures as high as 5000 bars. The conditions under which a waterjet orifice works, calls for a hard and easy to produce material and sapphire is an ideal choice.
