4 Axis Waterjet Cutting Machine: Precision, Bevel Cuts & Advanced Applications

Manufacturers working with thick materials or requiring angled edges often need more than a standard flat cutter. That is where a 4 axis waterjet comes into play. By adding a tilting head to the traditional X‑Y‑Z motion, this technology enables bevel cuts, undercuts, and complex geometries in a single setup. VICHOR has engineered reliable 4‑axis systems that deliver accuracy without slowing down production.

Unlike 3‑axis machines that cut only perpendicular to the surface, a 4‑axis waterjet can tilt the cutting head up to 60 degrees in one direction (or more with a true 5‑axis head). This capability is essential for weld preparations, countersinks, and parts that require angled edges. In this article, we explore everything from basic principles to selection criteria for a 4 axis waterjet.

What Is a 4 Axis Waterjet Cutting Machine?

A 4 axis waterjet system adds a rotary axis (usually the A‑axis) that tilts the cutting head. The workpiece remains stationary while the nozzle can move along X, Y, Z and rotate around a horizontal axis. This allows the jet to strike the material at an angle, producing bevels without refixturing.

Some configurations are called “4‑axis” because they control the tilt angle, while true 5‑axis machines also add a second rotational axis for full contouring. For most stone, metal, and composite applications, a quality 4‑axis waterjet provides the needed flexibility.

Difference Between 3‑Axis and 4‑Axis Waterjets

• 3‑Axis: Cuts vertically only (90° to the table). Ideal for straight cuts and outlines.
• 4‑Axis: Head tilts in one plane (e.g., left‑right). Creates bevels up to 60° without moving the part.
• True 5‑Axis: Full articulation for complex 3D shapes like turbine blades.

For most fabrication shops, a 4‑axis waterjet strikes the best balance between capability and cost.

Key Advantages of Using a 4 Axis Waterjet

Adding a tilting head opens new possibilities. Here are the main benefits you gain with a 4 axis waterjet:

• Bevel cuts in one pass – prepare weld edges or create countersinks without secondary operations.
• Reduced setup time – angled features are machined while the part is clamped once.
• Improved material utilization – nest parts more tightly because you can cut draft angles.
• Higher accuracy – eliminates errors from repositioning the workpiece.
• Extended application range – from thick steel with bevels to stone with decorative chamfers.

These advantages translate directly into faster turnaround and lower labor costs.

Applications of 4 Axis Waterjet in Industry

The ability to tilt the jet makes the 4 axis waterjet valuable across many sectors:

• Metal fabrication: Beveled edges for welding (V‑grooves, J‑preps) on plates up to 150 mm thick.
• Stone and tile: Chamfered edges for countertops, mosaic pieces with angled facets.
• Aerospace: Lightweight composites with tapered edges for bonding.
• Automotive: Trim panels and brackets that require draft angles.
• Architecture: Decorative panels with 3D effects created by varying cut angles.

In each case, the 4‑axis feature eliminates manual grinding or additional machining steps.

How to Choose the Right 4 Axis Waterjet for Your Shop

Selecting a 4 axis waterjet involves more than just checking the axis count. Consider these factors:

Cutting Envelope and Tilt Range

Determine the maximum part size. Standard tables range from 2×2 m to 3×6 m. Also check the tilt angle range – most 4‑axis heads offer ±45° to ±60°. Ensure the Z‑axis clearance accommodates tall parts when tilted.

Pump Pressure and Flow

For bevel cutting in thick materials, higher pressure (60,000 psi or more) maintains speed. A larger pump also supports multiple cutting heads if you plan to expand production.

Control Software and Compensation

4‑axis cutting requires sophisticated software to calculate the correct tool path and compensate for the jet’s taper. VICHOR machines include industry‑leading CNC with built‑in bevel compensation.

Build Quality and Support

The tilting mechanism must be rigid to maintain accuracy. Look for linear guides on all axes and a robust A‑axis drive. VICHOR provides detailed specifications and remote support.

Maintenance and Operation Tips for 4‑Axis Systems

Keeping your 4 axis waterjet in top shape ensures consistent bevel accuracy:

• Regularly inspect the tilting head for backlash or play.
• Clean the abrasive feed lines to prevent clogging, especially when cutting at steep angles.
• Check the mixing tube and nozzle wear more frequently – angled cutting can accelerate wear.
• Keep the tank water clean to avoid sediment buildup on the guides.
• Follow the lubrication schedule for all moving parts.

VICHOR provides detailed maintenance manuals and remote diagnostics to minimize downtime.
