Waterjet Cutting Machines

Waterjet cutting is a powerful and versatile industrial manufacturing process that utilizes a high-pressure machine and abrasive material to cut a variety of materials such as metal, stone, aluminum, and plastic. High-pressure water is combined with an abrasive material, such as garnet, to create a powerful jet that can easily cut through even the toughest materials. In Canada and around the world, waterjet cutting is valued for its numerous advantages, including precision, accuracy, and cost-effectiveness.

This cutting process is used on a wide range of materials using a cutting table and high-pressure water. During the cutting process, water is forced through a small nozzle at extremely high pressure (ranging from 20,000 PSI to 90,000 PSI), creating a fine, concentrated jet of water capable of accurately cutting thick materials. This is where renowned manufacturers such as OMAX, Flow, and KMT come in, producing high-quality equipment for this process.

To enhance cutting efficiency and reduce wear on parts, abrasive particles (such as garnet) are often added to the water stream. This abrasive water jet acts as a sandblasting process, using the abrasive particles to cut through the material.

Due to its versatility, waterjet cutting is a popular choice among manufacturers as it can be used to cut a variety of materials, including metals, plastics, composites, and even stone or glass. Additionally, because waterjet cutting does not produce a heat-affected zone (due to the low temperature of the water), it can be used to cut heat-sensitive materials or otherwise difficult-to-cut materials with other methods. It is a precise and cost-effective cutting method, ideal for a variety of industrial applications.

Waterjet cutting is a process used to cut a wide range of materials using high-pressure water and an abrasive substance.

Direct drive pumps and intensifier pumps are used in waterjet cutting equipment to provide the high-pressure water needed for cutting. Here are some advantages of a direct drive pump compared to an intensifier pump:

• Less maintenance: Direct drive pumps have fewer moving parts compared to intensifier pumps, which typically require regular maintenance for seals, pistons, and plungers to function properly. This means direct drive pumps may require less regular maintenance.
• Energy efficiency: Direct drive pumps generally use less energy than intensifier pumps since they don’t require a separate power source or electricity to generate hydraulic pressure.
• Reliability: Direct drive pumps may be less prone to leaks or other failures compared to intensifier pumps due to their simpler design and fewer moving parts.
• Lower noise level: Direct drive pumps tend to produce less noise than intensifier pumps, making them a better choice for environments where noise reduction is important.
• Lower operating costs: Given that direct drive pumps are typically more energy-efficient and require less maintenance than intensifier pumps, they can be more cost-effective in the long run.

Overall, direct drive pumps offer a simpler and more efficient option for high-pressure waterjet cutting, with lower maintenance needs and operating costs. However, intensifier pumps may still be preferred in certain situations, such as when cutting with multiple cutting heads or when higher pressures are required for materials with water-only cutting. It’s always a good idea to consult the manufacturer of the waterjet cutting equipment, such as Omax, to determine which pump is best suited for your specific needs.

The amount of water used by a waterjet depends on several factors, including the water pressure and flow rate, the size and type of the waterjet nozzle, and the specific application.

However, generally speaking, waterjet cutting machines can use anywhere from 0.5 to 5 gallons (2 to 19 liters) of water per minute. High-pressure waterjets typically use less water as they can cut more efficiently with less water. It’s also worth noting that some waterjet systems use a closed-loop system that recirculates the water, which can significantly reduce water consumption.

In particular, direct drive pumps used in these machines generally require less water compared to intensifier pumps. Direct drive pumps use a high-speed motor to spin a wheel, which pressurizes the water. Intensifier pumps, on the other hand, use hydraulic pressure to boost the water pressure. As a result, direct drive pumps are more efficient at converting energy into pressure and require less water for the same task as intensifier pumps since there’s no hydraulic fluid requiring cooling.

Depending on the machine model and specific usage, water requirements can vary. It’s recommended to check the specifications of your machine, whether it’s from the Omax brand or another, and use it responsibly, keeping environmental considerations in mind.

A waterjet cutting machine is capable of cutting a wide variety of materials at different thicknesses. The maximum thickness that a waterjet can cut depends on several factors, such as the power of the jet, the type and quality of the abrasive material used, and the type of material being cut.

Generally, waterjets can cut materials ranging from a few millimeters to several centimeters thick. Some high-powered waterjets are even capable of cutting materials over 30 centimeters (one foot) thick. It should be noted, however, that increasing the material thickness can slow down the cutting speed. Additionally, cutting very thick materials may require multiple passes of the waterjet, which extends the total cutting time.

The power of the waterjet, the size and quality of the nozzle, as well as the type and quality of the abrasive material used, all influence the thickness of material that can be cut. Furthermore, the cutting speed can also be affected by the material thickness, as thicker materials may require multiple passes to achieve the desired cutting depth.

It is important to remember that the maximum material thickness that can be cut with a waterjet may vary depending on the specific application and the material being cut. Some materials may be more challenging to cut than others, and the material thickness can also affect the precision and quality of the cut. Therefore, whether you are using an Omax machine or another brand, it is recommended to consult the machine’s technical specifications and conduct testing to determine the optimal settings for your specific application.

The power of a waterjet is generally measured in terms of horsepower at the nozzle and flow rate. The pressure is measured in pounds per square inch (PSI), while the flow rate is measured in gallons per minute (GPM). The efficiency of the pump must be considered. For example, a direct drive is efficient at 95%, which means you have 95% of the power at the nozzle, resulting in higher cutting speed and faster cuts compared to other pump types operating at 60-65% efficiency at the same pressure.

In general, the pressure of a waterjet ranges from 20,000 to 90,000 PSI, while the flow rate ranges from 0.5 to 8 GPM. The power of a waterjet can be calculated by multiplying the pressure and flow rate.

For example: a waterjet with a pressure of 60,000 PSI and a flow rate of 3 GPM would have a power of 180,000 horsepower (60,000 x 3 = 180,000). This level of power requires horsepower at the nozzle and can generate a cutting force capable of cutting materials up to several inches thick, depending on the type and quality of the material being cut. To obtain the flow rate or GPM, the pump efficiency must be taken into account, as you will need maximum power at the nozzle.

Therefore, the overall efficiency of the waterjet pump should be considered when determining its power. Volumetric efficiency should also be taken into account as it can play a significant role in the amount of material actually cut and the speed of the cut. Ultimately, the power of a waterjet depends on several factors.
