Waterjet cutting technology is known for its cold-cutting capability, allowing it to process almost any material without creating a heat-affected zone. This advantage makes waterjet cutting difficult for other technologies—such as laser cutting—to fully replace.
Traditionally, waterjet systems were mainly used in high-volume industrial machining factories. However, in recent years the technology has gradually expanded into new application environments, including:
- art studios
- small entrepreneurial workshops
- makerspaces
- university laboratories
- corporate R&D facilities
Compared with large industrial factories, these environments have very different requirements.
Typical characteristics include:
- low production rhythm
- frequent material changes
- multi-variety, small-batch cutting
- sometimes even one-off prototype processing
- limited workshop space
- users focused more on creation and experimentation rather than mass production
This shift in demand has led many waterjet manufacturers to release compact or small waterjet cutting machines.
However, these machines are designed for very different users and applications. This leads to an important question:
Is a small waterjet cutting machine the same as a desktop waterjet?
To answer this question, we will compare three widely discussed machines on the market:
- OMAX ProtoMAX
- WAZER Pro
- APW-A22S-GJ0505-DXACWZ
This comparison will help you understand their differences and choose the right machine for your application.
Small Waterjet Cutting Machine Overview and Specifications
Different Manufacturers and Market Positioning
Although the three machines are often grouped into the same category of small waterjet cutting machines, they are produced by manufacturers with very different backgrounds and target markets.
OMAX ProtoMAX
ProtoMAX is produced by OMAX, a well-known manufacturer of industrial abrasive waterjet systems.
The ProtoMAX system was developed primarily for:
- education
- training labs
- research institutions
It focuses on ease of use and software integration, rather than maximum cutting power.
WAZER Pro
WAZER Pro was developed by a startup company focused on bringing waterjet technology to makers and small workshops.
Its main design goals include:
- simplified operation
- compact footprint
- affordable access to waterjet cutting
As a result, WAZER Pro is popular in makerspaces and small creative workshops.
APW-GJ0505
The APW-A22S-GJ0505-DXACWZ is developed by APW, a manufacturer specializing in industrial waterjet systems.
Unlike many desktop-focused products, the APW machine is designed to bring industrial-level cutting capability into a compact format, making it suitable for:
- industrial laboratories
- materials research facilities
- precision manufacturing environments
Technical Specifications of the Small Waterjet Cutting Machine
Below are the key specifications of the three machines.
| Parameter | APW-GJ0505 | ProtoMAX | WAZER Pro |
| Cutting Area | 500 × 500 mm | 304 × 304 mm | 305 × 460 mm |
| Z-Axis Travel | 0–150 mm adjustable | 25 mm fixed | Fixed |
| Axis System | AC 5-axis | 3-axis | 3-axis |
| Maximum Pressure | 360–413 MPa (3600–4130 bar) | 206.8 MPa (2068 bar) | 59.3 MPa (593 bar) |
| Pump Power | 23.9–75 kW | 3.7 kW | 2.1 kW |
| Structure | Separate modules | Integrated | Integrated |
| Control System | Industrial CNC + CAM | OMAX Intelli-MAX | WAM + SD card |
Key Performance Comparison
Several technical indicators reveal significant differences between these machines.
Pressure
Pressure is one of the most critical parameters in a small waterjet cutting machine.
Higher pressure provides:
- stronger cutting capability
- faster cutting speeds
- improved performance on hard metals
For example:
| Machine | Maximum Pressure |
| APW-A22S | 413 MPa (4130 bar) |
| ProtoMAX | 206.8 MPa (2068 bar) |
| WAZER Pro | 59.3 MPa (593 bar) |
Low-pressure systems such as WAZER Pro are generally limited to thin sheets and softer metals.
Z-Axis Flexibility
Another important difference is the Z-axis capability.
| Machine | Z-Axis Travel |
| APW-GJ0505 | 0–150 mm adjustable |
| ProtoMAX | 25 mm fixed |
| WAZER Pro | Fixed height |
A larger Z-axis range allows:
- thicker materials
- fixtures and jigs
- more complex workpieces

FAQ
Technical FAQ
What materials can a small waterjet cutting machine cut?
A small abrasive waterjet cutting machine can cut a wide range of materials without generating heat-affected zones. Common materials include:
- Aluminum
- Stainless steel
- Carbon steel
- Copper and brass
- Glass
- Ceramic tiles
- Stone
- Engineering plastics
- Composite materials
Because waterjet cutting is a cold cutting process, it is particularly suitable for materials that are sensitive to heat deformation.
What is the typical cutting thickness for a small waterjet machine?
Cutting thickness depends on several factors, including:
- Pump pressure
- Orifice size
- Abrasive flow rate
- Material hardness
Small waterjet systems with 380 MPa (≈3800 bar) high-pressure pumps are typically used for:
- Thin metal plates
- Medium-hard alloys
- Laboratory material samples
For thicker industrial cutting, larger waterjet systems with higher power pumps are usually required.
Why is high pressure important for waterjet cutting?
Higher pressure directly increases the kinetic energy of the waterjet, which improves cutting capability.
Benefits of higher pressure include:
- Faster cutting speed
- Ability to cut harder materials
- Better cutting stability
- Improved efficiency in abrasive waterjet systems
In applications involving metal cutting or alloy material testing, high pressure is often a critical requirement.
Why do some waterjet machines use a 5-axis cutting head?
A 5-axis waterjet cutting head allows the nozzle to tilt and rotate during cutting.
Typical axis movement includes:
- A axis: ±75° tilt
- C axis: ±360° continuous rotation
This configuration allows the machine to:
- Compensate for taper in thick materials
- Perform beveled cutting
- Cut complex 3D geometries
- Improve edge quality
Five-axis systems are commonly used in industrial laboratories and advanced manufacturing environments.
What kind of workspace is needed for a compact waterjet machine?
Compact waterjet systems are designed to reduce installation requirements compared with large industrial machines.
However, users should still prepare:
- A stable power supply
- Water supply and filtration
- Abrasive storage and handling
- Wastewater management
A machine with a 500 mm × 500 mm cutting platform can often fit into:
- laboratories
- small workshops
- research facilities
- prototyping environments
