How To Maintain A WaterJet Cutting Machine For Maximum Efficiency?

A waterjet cutting machine is not just a piece of equipment; it's your long-term production partner.

With proper maintenance, a waterjet cutting machine will operate smoothly, accurately, and reliably.
Without proper maintenance, even the best machine will gradually lose accuracy, efficiency, and reliability.
In KUNDA's daily work, we've observed that customers who follow proper maintenance procedures achieve better cutting quality, lower operating costs, and significantly extended machine lifespan.
The following is a maintenance guide compiled from our years of experience, hoping to provide you with some assistance:
1. Water Quality
Water is the foundation of a waterjet system. Poor water quality can slowly damage internal components, especially the pump, seals, and nozzles.
Therefore, we recommend installing a suitable multi-stage water filtration system, regularly checking for clogged filters, and monitoring water hardness and mineral content.
2. WaterJet Pump
Whether your system uses a booster pump or a direct-drive pump, we need to constantly monitor the pump's operating status.
Key maintenance points:
Check oil level and quality, pay attention to any abnormal noise or vibration, and regularly inspect seals, check valves, and connectors.
Strictly adhere to the recommended maintenance schedule.
A healthy pump provides stable pressure, which directly affects cutting speed and edge quality.
3. Nozzles, Orifices, and Mixing Tubes
Consumables may be small, but their impact is significant. Worn parts can lead to unstable jets, wider kerfs, and reduced cutting efficiency.
Regularly inspect and replace wear parts according to the manual. Ensure perfect alignment during installation.
Then, try to choose high-quality abrasives, as high-quality abrasives can effectively reduce wear on the machine's internal components.
At KUNDA, we often remind our customers: well-maintained nozzles run smoothly; worn nozzles will give warnings before failure occurs.
4. Maintain Stable Abrasive Flow and Clean Conveying Lines
In Abrasive Waterjet Systems, the abrasive flow must remain stable and dry.
Therefore, we need to keep the abrasive dry and avoid moisture.
Regularly clean the abrasive hopper and feed lines.
Check the abrasive metering device for blockages.
5. Keep the Motion System Clean and Accurate
The accuracy of the cutting head depends on the accuracy of the motion system beneath it. Therefore, we need to regularly clean the linear guides and ball screws,
lubricate moving parts according to schedule,
and check belt tension and motor alignment.
Precise machine movement ensures more accurate cutting.
6. Height Control System
Some customers' machines may be equipped with a laser height measurement system.
The laser height measurement system helps maintain the correct distance between the nozzle and the material.
This effectively prevents nozzle collisions, improves cutting edge quality, and extends consumable life.
Therefore, we recommend that you regularly calibrate the system for accuracy and responsiveness.
7. Follow a Preventive Maintenance Plan
Waiting until the machine breaks down before performing maintenance is the most expensive maintenance strategy.
A structured maintenance plan should include:
Daily visual inspections
Weekly cleaning
Monthly performance checks
Annual comprehensive system maintenance
Preventive maintenance ensures smooth machine operation and avoids unexpected downtime.

At KUNDA, we design our waterjet cutting machines with maintenance needs in mind. Each system incorporates easy-to-maintain components, reliable parts, and clear service guidelines.
We also provide:
Detailed maintenance manuals
Professional technical support
Fast delivery of spare parts
Customized maintenance solutions based on customer workload
Because a well-maintained machine is not only more efficient but also more profitable.

Maintaining a waterjet cutting machine requires consistency, attention to detail, and respect for the system. Clean water, stable pressure, aligned consumables, precise movement, and well-trained operators all work together to achieve maximum efficiency.
Treat your waterjet cutting machine like a trusted production partner, and it will reward you with reliable performance for years to come. With KUNDA's experience and support, keeping your machine at peak efficiency will become a practical daily routine, not a challenge.
