Summary

The average cost of using water jet cutting equipment can reach $6 to $9 per hour. Most of the cost comes from self-consumed abrasives, and depending on the number of cutting heads and water pressure, the cost will increase qualitatively. Now, how much water jet cutting costs depends on a number of factors. In this case, the cost of consumables and electricity is not the only determining factor. Even the material you're researching plays an important role.


Waterjet Cutting Costs: Everything You Need to Know! Is water jet cutting expensive?

Yes, waterjet cutting costs a lot, but not yet to the point of being unaffordable. The cost of water jet cutting depends on many factors. Pay the carrier's fees. Consumables like water, fuel, and abrasives all add to the overall cost. This is the original fee only. Stress levels can also significantly increase costs. Thicker materials require more cutting power and also more time. So water jet cutting is quite extensive.


Does the cost depend on the material?

The water jet can cut many materials with excellent precision. Most water jets can use 60,000 to 90,000 PSI. The material you use will determine the amount of pressure you need to use. The water jet can cut hard materials such as stone, ceramic, metal, and glass. Soft materials such as leather, cloth, foam, rubber, etc., and composite materials such as nylon, bakelite, etc. can also be cut. Different materials have different strength levels. You can treat most glass with 60k PSI and regular fine abrasives. On the other hand, something like titanium requires more water pressure to get the job done. The greater the pressure, the higher the cost. The natural density of the material is not the only factor that affects the cost of waterjet cutting. The thickness of the material used is also a key factor. A standard water jet can penetrate titanium up to 17cm thick. For thicker materials, HP is usually higher as this speeds up the process. Increasing HP also increases abrasive consumption and power consumption. However, this ends up being cheaper than running at a lower HP and wasting precious materials and time.


What is the cost of water jet?

As I mentioned earlier, there are many factors that determine the overall cost of waterjet cutting. Now I'll explain each item in detail so you can get a rough idea of ​​the total cost.

• Abrasive

Abrasives are mineral components in mud, and the most commonly used materials are sand, garnet, silicon carbide, etc. The usual cost of garnet is about $0.26/KG, and the price of other materials is about the same. Water jets use about 15-20kg of abrasive per hour on average, so costs can quickly add up. The cost per day usually depends on how long you plan to run the water jet. However, you can recycle the abrasive. You can cycle the same abrasive a few more times before it loses its edge. Cutting power increases with subsequent cycles because smaller particles have sharper edges. But they will eventually lose their edge within a few cycles. Even if you could recycle the mud, it would still cost more than half the total cost of using a water jet.

• Replacement parts

Water jets use high-pressure abrasive-infused mud to cut everything. This method is effective due to the concentration of pressure. However, pressure does not only affect the material being cut.

Some parts of the water jet are also affected by the force and will eventually wear out. Once these parts are subject to a certain level of wear, they need to be replaced frequently. The most common replaceable parts are pump seals and focus tubes. This is the second largest cost of using a water jet.

•Electricity

The power consumption of the water jet is moderate compared to other industrial grade cutters. Power consumption depends a lot on the materials you use. Thicker materials require more consumption as you need to increase your HP to 90.

The power consumption cost is about 10% of the total cost of running the waterjet. 10% of the total cost is not much compared to the cost of abrasives.

• Water consumption

Water is the most consumed resource for water jet cutting machines. The average spray volume per minute is 3.7 liters. Water consumption depends entirely on orifice size. The average level is about $0.45 per ton. Although water jets are the largest of the consumable resources, their water consumption costs only account for about 3-5% of the total cost of using water jets. This is because the recovery of water is much easier than the recovery of abrasives. With a suitable recycling system, you can recover up to 90% of your water. As long as it's clean enough, it can keep running

Water cutting instead of other cutting methods

Water jet cutting machines are relatively more expensive than other industrial cutting machines such as plasma and laser. So why bother to replace them with it?

The first answer is: precise. One of the main reasons to use a water jet cutter is its precision and finish quality. Water jet cutters are finer than heated cutters. An astonishing 0.13mm accuracy can be achieved even through the toughest materials. Another reason to use a water jet cutter is its environmental friendliness. Water jet cutters generate no heat, they use mineral-based abrasive materials, and require very little electricity. All of these combine to make water jet cutters extra natural and friendly. Flexibility is another reason why waterjet cutters are more viable than other options. Both laser and plasma cutters have certain materials that do not penetrate properly. On the other hand, water jet cutters can handle any type of material. As long as the water pressure and HP are high enough. By changing the type of abrasive used, the waterjet cutter can be given more flexibility. Smaller pieces are more accurate, while larger pieces work better with thinner materials. Water jets also have higher penetrating power than plasmas and lasers. Therefore, it can cut materials much thicker than they are. So, all in all, depending on your use of water jets, water jets are a good investment and in many ways better than other cutting methods.

Conclusion

Running a regular waterjet cutting machine can cost $6.5 to $9 per hour, so it's not that bad. Best of all, they have excellent recycling capabilities, which greatly reduces overall costs. Almost 70% of the cost comes from abrasives, and if you can get a good deal on abrasives, you can reduce the cost to a great extent. If so, your biggest expense will be wearing parts.
