Waterjet Operating Costs Breakdown
Understanding per-hour operating costs is critical for quoting waterjet work profitably:
| Cost Component | Per Hour Estimate | Notes |
|---|---|---|
| Garnet abrasive | $8-$20 | Largest ongoing cost; 0.5-1.5 lbs per minute |
| Electricity | $3-$10 | Depends on pump size and local rates |
| Water | $0.50-$2 | Municipal water; recycled systems reduce this |
| Pump consumables | $3-$8 | Seals, check valves, orifices (amortized) |
| Nozzle wear parts | $2-$5 | Mixing tube and orifice replacement |
| Total per hour | $16.50-$45 |
For a typical undermount sink cutout (10-15 minutes of cutting), the operating cost is roughly $3-$11 per cutout. When you're charging $150-$250 per sink cutout, the margins are healthy -- as long as you're not wasting time on setup and file preparation.
DXF to Waterjet: Getting Your Files Right
The most common source of wasted waterjet time is bad file input. Here is the chain that matters:
- Template -- Digital laser template captures the actual jobsite dimensions
- Design layout -- Template data is used to position pieces on the slab
- DXF export -- Cutting paths are exported as DXF files
- Waterjet import -- The DXF file is loaded into the waterjet's CAM software
- Tool path generation -- Software creates the actual cutting path with lead-ins, speeds, and quality settings
- Cut -- The machine executes the program
Problems at step 3 and 4 are the most common. DXF files with duplicate lines, open polylines, or incorrect scaling cause the waterjet software to generate bad tool paths or reject the file entirely. SlabWise's Template Verification checks DXF files for these issues before they reach your CNC or waterjet, catching errors that would otherwise waste machine time and material.
FAQ
How much does a waterjet cutter cost for stone work?
Standalone stone waterjet cutters range from $80,000 for entry-level models to $300,000+ for high-production machines. Combined saw/waterjet machines like the BACA SawJet run $250,000-$400,000.
Can a waterjet cut any type of stone?
Yes. Waterjets cut granite, marble, quartzite, soapstone, porcelain, engineered quartz, and every other stone or stone-like material. They also cut metal, glass, and tile, making them versatile shop tools.
How thick can a waterjet cut stone?
Most stone waterjets comfortably cut up to 6" thick material. Standard countertop thicknesses of 2cm (3/4") and 3cm (1-1/4") are well within the normal operating range. Thicker cuts simply take longer.
What does garnet cost for a waterjet?
Garnet abrasive costs $0.20-$0.40 per pound, and a typical waterjet uses 0.5-1.5 pounds per minute of cutting. Annual garnet costs for a busy stone shop run $5,000-$15,000 depending on usage.
How accurate is a waterjet on stone?
Modern CNC waterjets achieve +/- 0.003" to 0.005" positional accuracy. Taper (the kerf widening toward the bottom of the cut) can be managed with 5-axis cutting heads that tilt to compensate.
Waterjet vs. bridge saw -- which do I need?
Both. A bridge saw handles straight cuts, profiling, and miters faster and cheaper. A waterjet handles curves, sink cutouts, inlays, and intricate shapes. Most stone shops need both machines, or a combo unit like the BACA SawJet.
How loud is a waterjet?
Standard above-water cutting produces 80-95 decibels -- hearing protection is required. Submerged cutting (available on some machines) reduces noise to 70-75 decibels, roughly the level of a normal conversation.
How much water does a waterjet use?
A typical stone waterjet uses 0.5-2 gallons per minute. Most of this water is recycled through a closed-loop system. Fresh water makeup is minimal -- typically 50-100 gallons per day.
How often does a waterjet pump need maintenance?
Intensifier pumps need seal rebuilds every 500-2,000 hours of cutting. Direct drive pumps generally require less frequent maintenance. Budget $3,000-$8,000 annually for pump consumables on either type.
Can one person operate a waterjet?
Yes. Modern CNC waterjets are designed for single-operator use. After loading the material and importing the DXF file, the operator starts the program and monitors the cut. Material loading and unloading are the most labor-intensive parts.
