FAQs

What types of waterjet systems do you service?

We specialise in a wide range of CNC waterjet systems, including Techni Waterjet machines, Quantum Electric Servo Pumps, and KMT hydraulic intensifiers. If you’re unsure whether we can support your equipment, just reach out—we’re always happy to help.

Do you offer emergency breakdown support?

Yes. We understand that downtime costs money, so we prioritise fast response times for breakdowns. Our goal is to get your machine back up and running as quickly and efficiently as possible.

Do you supply parts and consumables?

Absolutely. We supply a full range of high-quality parts and consumables, including access to genuine components through Hypertherm and Quantum. This ensures reliability, performance, and long service life.

Do you service customers outside your local area?

Yes. While we have technicians based in both QLD and NSW, we support customers across Australia and New Zealand. We often coordinate service trips to help minimise travel costs for our clients.

Why should I choose Jet Tech over other service providers?

Customers choose Jet Tech because they trust us to deliver. We combine hands-on expertise with honest advice, fast response times, and reliable workmanship. We don’t just fix problems -we provide long-term solutions that keep your business running.

How do I optimise cutting quality on my waterjet?

Cut quality comes down to the right balance of pressure, feed rate, abrasive flow, and nozzle condition. Worn orifice and focusing tubes, incorrect garnet feed, or poor alignment are the most common causes of taper, striations, or rough edges. Regular inspection and tuning are key to consistent results.

How do I know if my orifice or focusing tube needs replacing?

Signs include loss of cutting power, increased taper, rough edge finish, or higher abrasive consumption. A worn orifice can also cause stream instability, while a worn focusing tube will reduce accuracy and efficiency. Preventative replacement is far cheaper than poor cut quality or wasted material.

What causes pressure loss in a waterjet system?

Pressure loss can be caused by worn seals, leaking high-pressure components, check valve issues, or problems within the intensifier or pump system. Even small leaks or worn parts can significantly impact performance, so early diagnosis is critical.

How do I set the correct garnet flow rate?

Too much garnet wastes abrasive and can reduce cutting efficiency, while too little results in poor cutting performance. The ideal flow rate depends on your orifice size, material type, and cutting speed. Fine tuning is essential, and we can help dial this in for optimal performance.

How often should I service my intensifier or pump?

Service intervals depend on usage hours, pressure levels, and operating conditions. Regular maintenance of seals, check valves, and hydraulic components is essential to avoid unexpected failures. Preventative servicing will always cost less than a major breakdown.

Why is my waterjet cutting slower than usual?

Common causes include worn consumables, incorrect garnet flow, pressure loss, or poor water quality. Even small changes in system performance can noticeably affect cutting speed and efficiency.

Does water quality affect waterjet performance?

Yes—water quality is critical. Poor filtration or high mineral content can reduce component life, damage seals, and affect cutting consistency. Proper filtration and water treatment help protect your system and improve reliability.

What are the signs of a failing intensifier seal?

Typical signs include pressure fluctuations, reduced maximum pressure, water leakage, or inconsistent cutting performance. Catching seal wear early can prevent costly damage to other components.

Can I run my machine while it is due for maintenance?

You can—but it’s risky. Running worn components often leads to reduced performance, poor cut quality, and increased chance of major failure. Scheduled maintenance keeps your system reliable and avoids costly downtime.

How can I reduce operating costs on my waterjet?

Optimising consumable life, dialling in garnet flow, maintaining correct pressures, and servicing components regularly all reduce overall costs. Efficiency in setup and maintenance has a direct impact on your bottom line.
