Water jet cutting is a versatile and efficient method used in the manufacturing industry for cutting a wide range of materials. The cost of water jet cutting can vary significantly based on several factors, including the type of material being cut, the thickness of the material, and the complexity of the cut. Here, we explore the various costs associated with water jet cutting and provide a pricing comparison table for better understanding.
Operating Cost
On average, the cost to run an abrasive waterjet can be as low as $20 per hour. However, depending on various factors, waterjet cutting could cost between $20/hr – $40/hr to run a waterjet with a single abrasive cutting head at 60,000 psi. This estimation does not include labor or capital repayment costs.
Consumables Cost
| Part Name | Approximate Cost | Approximate Lifespan |
|---|---|---|
| Nozzles | $80 | 80 hours |
| Orifice | $15 | 40 hours |
| Mixing Chamber | $150 | 400 hours |
| High-Pressure Pump Seal | $120 | 500-1000 hours |
System Cost
Pricing for small waterjet cutting systems can start around $60,000, and complete custom systems can reach into the millions, depending on the application and requirements.
Pricing Comparison Table
The table below shows the cost of operating a waterjet cutter for one hour. All costs are in US dollars.
- Abrasive Cost: Based on using garnet sand at a rate of 1 pound per minute.
- Power Cost: Based on an electricity rate of $0.10 per kilowatt-hour.
- Cost of Parts: Based on the average cost of replacing worn-out parts, such as nozzles, orifices, and mixing chambers.
- Water Cost: Based on the average cost of water in the United States.
- Misc Cost: To cover other expenses, such as labor and overhead.
| Type of Cost | Waterjet Cutter 1 (30 HP Pump, 0.01″ Orifice) | Waterjet Cutter 2 (50 HP Pump, 0.014″ Orifice) | Waterjet Cutter 3 (60/75 HP Pump, 0.016″ Orifice) |
|---|---|---|---|
| Abrasive Cost | $10.50 | $19.50 | $24.00 |
| Power Cost | $2.60 | $2.60 | $2.60 |
| Cost of Parts | $3.00 | $3.50 | $3.70 |
| Water Cost | $0.30 | $0.60 | $0.75 |
| Misc Cost | $3.50 | $4.00 | $4.25 |
| Total Cost | $19.90 | $31.90 | $37.50 |
Please note that these costs are just estimates. The actual cost of operating a waterjet cutter will vary depending on a number of factors, such as the type of material being cut, the thickness of the material, and the cutting speed. Water jet cutting is a cost-effective solution for various cutting needs in the manufacturing industry. However, it is essential for businesses to consider all associated costs, including operating costs, consumables, and system costs, to make an informed decision. By comparing different pricing options and considering the specific requirements of the application, businesses can optimize the cost and efficiency of water jet cutting.
