How to Properly Maintain Your Waterjet Cutter and Extend Its Service Life?

If your machinery is an integral part of your production, you need to have a manageable maintenance program in place to keep it always in tiptop shape. The same is true if you require the use of a waterjet cutter for your machination and fabrication needs

When pieces are required, they maintain well machinery and equipment; they always deliver their best performance. If you have a waterjet system and it’s helping your organization remain at the top of its game, how far do you think you should go to keep it in suitable form and balance? 

However, it is sad to know that there are a handful of CNC shops and operators out there that seem to underestimate the power of proper care and maintenance for their machines. If they will slack in this area or will be lax in giving proper servicing for their systems, it will risk impeding their productivity.

Frequency of Maintenance

Waterjet systems are qualified mechanical equipment, and like any other machines, they need proper maintenance to keep running smoothly. 

Expect that you will need to change their nozzle parts, daily. Know beforehand that you will need to replace pump parts less frequently, and yet must be regular enough. Anticipate that you need to always have critical spares at hand, this way you won’t have to stall your machining project while there are no available spare parts and you are waiting for your ordered replacement to arrive.  

If you are using hard water for your machining concerns, there are two options you can consider. You will either need to maintain your system and parts more often, or you will need to have access to a good filtration system and reliable water softener solution.  

Ease of maintenance

If you know exactly how to replace the brake pads of your car, then that goes to show that you have all it takes to keep your abrasive jet going. To make this happen, you need a good manual and a day’s training. On certain occasions, you may require phone tech support. 

It is natural for mixing tubes to wear out easily, but you can replace them in no time. As for the pumps, they often require periodic seal changes. Regarding pump design, seals can be anywhere from quite awkward to quick and easy and time hog to replace.  

Start with Clean Water

Using water that contains dissolved minerals, impurities, or any random particles to your waterjet machine risks getting into your equipment’s high-pressure components. If that happens, it will speed up your machine’s wear and tear. 

The natural tendency of dissolved minerals in water is to get deposited and accumulated right at the top of the jewel. If this happens, it will compromise the cutting efficiency of your waterjet cutter. The worst thing that can happen here is it will deflect it sideways and cause it to land on your mixing tube side.  

Keep this in mind, water quality has a direct impact on the maintenance work your waterjet system will require. If you are using better water quality, then you are likely to have less frequent maintenance concerns for it. It works to your advantage because that means to say that you can handle more cutting and slicing work, generating revenue for your business.
