Waterjet Orifices: Single Crystal Diamond, tetraCORE™ Diamond, Ruby and Sapphire

At dtiEXACT, we manufacture high-quality waterjet orifices for use in the cleaning and waterjet cutting industries. We supply a line of waterjet orifices made with a selection of reliable materials, including diamond, ruby, and sapphire. Each of these materials offers numerous benefits, and dtiEXACT’s solutions offer unique advantages that make our products consistently dependable.

Diamond Orifices

Many applications use diamond waterjet orifices, which produce a jet stream that’s more cohesive than either sapphire or ruby. Because of this, diamond orifices tend to yield longer mixing-tube life, along with higher cutting power. Diamond orifices work with equipment of 40k to 100k PSI, and certain applications use them to perform long cuts on more expensive materials that may otherwise be destroyed due to mid-cut orifice failure by other less precise orifice types.

Our Premium dtiCORE Diamond orifice is the most superior diamond orifices available. Made from the world’s most flawless diamonds, these orifices are devoid of fractures, inclusions, or carbon spots. This enables them to withstand water pressures as high as 100,000 PSI, without experiencing any wear or erosion.

Sapphire waterjet orifices work for applications with less critical requirements because they are more susceptible to damage in certain high-pressure applications.

At dtiExact, we manufacture sapphire orifices of the highest quality in the waterjet industry. Depending on our customers’ needs, we offer both standard or custom sizes and integrate them into a variety of assembly styles.

Benefits

Some of the key benefits and considerations of sapphire orifices include:

  • Rigid corundum construction
  • A 9.0 rating on the Mohs hardness scale
  • Life expectancy to an average of 40 hours of life from immediate failure
  • Orifice ID edge degradation resulting from high pressure use and/or impacts
  • Compatibility for most applications of 60k PSI or less

Design

Sapphire orifices feature several unique design elements, such as:

  • Internal geometries initially intended for pure water cutting
  • Sharp edge internal dimension technology
  • Long, coherent jet streams with more vulnerability to debris impact than diamond or ruby
  • Lacks precise alignment

Ruby Orifices

Ruby waterjet orifices are similar in their properties to sapphire orifices. Like sapphire orifices, they are ideal for lower-demanding applications because they are prone to becoming damaged unpredictability because of their pink/red tint, it is simple to discern a ruby nozzle. The industry typically produces ruby with an inlet more conducive to abrasive cutting therefore they tend to hold up in high-pressure applications better than sapphire.

dtiEXACT offers both standard and custom ruby orifice assemblies based on your specifications, with some of the best materials available to meet your application’s unique requirements.

Benefits

Ruby orifices offer the following features:

  • 9.0 rating on the Mohs hardness scale
  • A lifespan of anywhere from immediate failure up to 40 hours
  • Less coherent jet streams that continue to degrade as the product experiences wear
  • Degradation of the orifice ID edge throughout the product’s life
  • Applicable for systems using 60k PSI or less

Design

Design elements of ruby orifices include:

  • A more robust inlet flare compared to “sharp edge” orifices
  • Originally designed for abrasive cutting
  • Shorter jetstream length but an increase in vacuum for pulling in abrasive
  • More capable of withstanding debris impact compared to sapphire
  • No precision alignment

Below, we’ve highlighted some of the most common machining processes and outlined key considerations to keep in mind when vetting your options to serve as a helpful machining process and material selection guide. 

Common Machining Processes

Machining is a broad term encompassing manufacturing processes that turn a workpiece into the desired component by removing material. Some of the most commonly used are: 

Swiss Machining

Swiss machining is a machining process generally used to create small, complex, and precise components in high volumes. Compared to traditional lathe processes, it offers tighter part tolerances, faster tooling changes, a lower chance of part deflection, and a smaller need for secondary processing, all of which can lead to increased productivity and profitability for the manufacturer.  

This machining process can accommodate a variety of metal and non-metal materials. Examples include aluminum, brass, copper, stainless steel, steel, and plastic. When selecting a material for Swiss machining operations, it is vital to consider how different factors will affect the overall project, including with regard to machining speed, retooling frequency, and production cost. 

CNC Turning

Computer numerical control (CNC) turning is a machining process that utilizes a combination of software and hardware to control the motions and actions of machine tools and workpieces. The stationary machine tool(s) remove(s) excess material from a rotating workpiece to create the desired component. Compared to manual turning methods, it offers better precision, faster speeds, higher efficiency, and safer operator conditions, resulting in high-quality components that are made cost-effectively and time-effectively.

This machining process can be used for various metal and non-metal materials. Examples include alloy steel, aluminum, brass, bronze, carbon steel, copper, stainless steel, titanium, UHMW, and other plastics.

Vertical Milling

Vertical milling is the most common milling method. It uses milling machines with vertically oriented spindles to hold and rotate the cutting tool(s) against the stationary workpiece to remove excess material. It offers a number of advantages over horizontal milling, including greater visibility during operations, easier use requirements, and lower equipment costs.

Laser Cutting & Drilling

Laser cutting and drilling are manufacturing processes that utilize high-powered lasers to form cuts and holes on a workpiece. Compared to conventional cutting and drilling processes, they offer greater accuracy and precision, shorter lead times, and broader design freedom. 

These processes are excellent for thin or thick materials. They can easily create cuts or holes in metals and other materials that would be difficult to process using other methods, such as diamonds. 

Waterjet Orifice RetainersWaterjet Cutting

Waterjet cutting is a manufacturing process that uses high-pressure waterjets to cut a workpiece into the desired shape and size. It offers a variety of advantages over other cutting processes, such as better edge quality, higher cutting accuracy, and lower risk of thermal distortion. 

This manufacturing process can be utilized for a range of materials, including metals, plastics, wood, and stone. It is highly effective at cutting hard or thick workpieces that would be too difficult for other methods, such as heat treated alloy steel.  

Selection Considerations for Machining Processes

While all machining processes produce components by removing excess material from the workpiece, each has distinct benefits and limitations that make it suitable for different manufacturing projects. The trick to choose the right process(es) for a project is evaluating all of these benefits and limitations and selecting the machining method(s) that best suit(s) your needs. Some of the factors to consider when evaluating your options include: 

  • Complexity: The machining process(es) you choose should be able to accommodate your component design, whether it is simple or complex. 
  • Tolerances: The machining process(es) you choose should be able to produce your components to your specifications, including with regard to tolerances. 
  • Timeframes: The machining process(es) you choose should be able to generate the parts/products you need in the volumes you need within the timeframe you need them. 
  • Budget: The two main costs associated with manufacturing projects are tooling cost and part cost. It is important you choose a machining process whose cost of tooling and part production fit within your project budget. 
  • Material: The machining process(es) you choose should be able to handle the materials you select, whether they are hard or soft and thick or thin. At dti EXACT, we can machine various materials, including aluminum, brass, bronze, copper, carbon steel, stainless steel, tool steel, specialty alloys, plastics, and diamond. We can work with you to find the best material for your project.
