Selecting the right waterjet cutting system requires evaluating two core components: the high-pressure pump system and the CNC cutting table. The choice depends primarily on your material types, thickness, required edge quality, and production speed targets .

High-Pressure System Selection

The pump pressure determines cutting capability and efficiency. For general-purpose cutting of materials up to 30mm thick (metals, stone, ceramics, glass), a 300MPa (30HP) system offers an economical solution with lower operating costs . For materials exceeding 30mm in thickness—such as steel, aluminum, copper, and stone—a 380MPa (50HP) system is recommended for faster cutting speeds and superior edge quality . For demanding applications involving extra-thick or high-strength materials, 420MPa (50HP) or even 620MPa (100HP) systems deliver enhanced performance .

As a general rule, each cutting head requires approximately 50HP for cutting materials over 0.5 inches (12.7mm) thick . Higher pressure also accelerates cutting speed by increasing jet velocity and abrasive particle momentum .

Cutting Table Selection

Table size should match your workpiece dimensions, nesting requirements, and material handling methods . A good rule of thumb is to allow the table size to accommodate your largest typical workpiece with room for future expansion.

Consider these platform configurations:

• Gantry-type: Compact structure with fixed installation, ideal for consistent material sizes and regular loading/unloading routines .

• Cantilever-type: Offers greater loading space with the motion mechanism separate from the cutting platform—recommended for irregularly shaped materials or job shops handling diverse workpieces .

For drive systems, stepper motors are cost-effective when cutting speeds stay below 3,000 mm/min. For higher speeds exceeding 3,000 mm/min, AC servo motors provide better speed stability and precision .

Optional Features

Consider adding an automatic abrasive delivery system to reduce labor and prevent cutting interruptions . Dual or multi-head cutting configurations can double productivity for small, high-volume parts . For systems above 30HP, a water softener is recommended to extend high-pressure seal life .
