One of the most persistent misconceptions in manufacturing is that waterjet cutting is too slow for mass production. While a single waterjet nozzle does have a maximum linear cutting speed dictated by hydraulic horsepower and kerf depth, high-volume manufacturers overcome this limitation completely through multi-head waterjet cutting.

By mounting two, three, or four cutting heads onto a single CNC bridge — driven by a high-output intensifier pump — a multi-head waterjet cuts identical parts simultaneously. A job that takes 8 hours on a single-head machine is finished in just 2 hours on a 4-head system, slashing labor costs, overhead, and floor space requirements.

How Multi-Head Waterjet Systems Operate

Multi-head machines feature two or more cutting heads positioned along the transverse bridge axis. Wonlean designs multi-head systems in two functional configurations:

🔗 Synchronous (Linked) Multi-Head

All heads are mechanically linked at fixed or motorized intervals (e.g. 300 mm spacing). They follow the identical CNC program simultaneously, cutting identical duplicate parts in parallel. Ideal for gaskets, brackets, flanges, and standard tiles.

🎛️ Independent Multi-Z-Axis (Dual Bridge)

Each cutting head is equipped with independent servo drives and programmable Z-axis height sensing. Heads can be spaced automatically via CNC software to optimize sheet nesting and handle asymmetric batch layouts.

Production Math: Single-Head vs. Multi-Head Economics

Let's examine the real-world manufacturing economics of producing a batch of 500 stainless steel 316 flanges (150 mm diameter, 10 mm thickness):

Production Metric	Single-Head CNC Waterjet	Wonlean Dual-Head (2x)	Wonlean Quad-Head (4x)
Cutting Time per Part	2.4 minutes	1.2 minutes (effective)	0.6 minutes (effective)
Total Batch Time (500 pcs)	20.0 hours	10.0 hours	5.0 hours
Operator Labor Cost (@ $30/hr)	$600	$300	$150 (75% savings)
Floor Space Occupied	1 Table (35 m²)	1 Table (35 m²)	1 Table (38 m²)
Required Capital Investment	1 Complete Machine	+15% to +25% cost	+35% to +50% cost

Key Takeaway:

Instead of purchasing four individual waterjet machines (which requires 4x operators, 4x factory floor space, and 4x maintenance overhead), a single Wonlean 4-head waterjet delivers equivalent batch output with a tiny fraction of the capital and overhead expenditure.

Pump Sizing for Multi-Head Cutting: The Hydraulic Formula

You cannot simply screw four cutting heads onto a standard small pump. Each waterjet nozzle orifice requires a specific water flow rate at full pressure. Wonlean matches pump horsepower directly to orifice size:

Dual Head (2x 0.25 mm Orifices): Requires 3.4 L/min water delivery at 420 MPa → Powered by a 37 kW (50 HP) intensifier pump.

Triple Head (3x 0.25 mm Orifices): Requires 5.1 L/min water delivery at 420 MPa → Powered by a 55 kW (75 HP) intensifier or dual-intensifier parallel setup.

Quad Head (4x 0.20 mm Orifices): Requires 5.6 L/min water delivery at 380 MPa → Driven by Wonlean's dual-hydraulic high-capacity pump system.

High-Volume Target Applications

🏭 Gasket & Seal Production

Cutting thousands of rubber, silicone, graphite, and cork gaskets using 4 pure-water heads at speeds up to 15,000 mm/min.

🏛️ Stone & Tile Repetition

Cutting standardized marble borders, mosaic squares, and ceramic subway tiles in continuous multi-row production.

🔧 Pipe Flanges & Washers

Batch slicing round flanges from 12 mm carbon and stainless steel sheets with synchronized dual or triple heads.

🚗 Automotive Sound Dampening

High-speed trimming of automotive acoustic insulation foam and carpet panels with pure water multi-jet manifolds.

Frequently Asked Questions

Q: Can I use just one head on a multi-head waterjet machine for custom one-off parts?

A: Absolutely. Wonlean multi-head systems allow you to shut off individual heads pneumatically via the CNC touchscreen. The remaining active head functions exactly as a standard single-head machine across the full table envelope.

Q: How does abrasive distribution work evenly across all heads?

A: Wonlean integrates independent digital abrasive hoppers for each individual cutting head. Each hopper meters garnet with electronic weight calibration, guaranteeing identical abrasive flow rates (±3%) across all nozzles.

Q: How does distance adjustment work between heads?

A: You can adjust head spacing either manually with precision rack-and-pinion scales or upgrade to motorized CNC-controlled positioning where the spacing auto-adjusts based on the nested CAD program.
