The Pros and Cons of Waterjet Cutting Machines

The Pros and Cons of Waterjet Cutting Machines

Among the many different cutting methods we now have, the use of a topnotch waterjet cutting machine, is by far, one of the most indispensable machining processes. We can have it as an immediate substitute to many other cutting methods we use and have applications for, but like many others, this too has limits of its own.

For people who are involved in the waterjet metal cutting business, it is of paramount importance that they know exactly what these limitations are.  

But before anything else, we need to define what waterjet cutting machines are?

They are special cutting tools that make use of a jet stream of high-pressure water to cut through various materials. Due to their intense power to penetrate hard objects, they are utilized in cutting metals.

The inspiration for this cutting edge technology comes from nature itself, soil erosion. If the high-pressure water is coupled with abrasive particles, it further intensifies its power and the process of cutting through an object speeds up many times over.

One effective way for a machining and metal fabrication shop to stand out above the competition is by employing the use of waterjet cutting technique. This technology maintains a good reputation in as far as quality and advantages over other methods are concerned, but like all the others in this space, they have their own share of disadvantages too. It is also worth looking into them as well.

One of the ways certain shops are standing out amongst their competitors is by employing the waterjet cutting method of machine milling. While it is a good way to grab attention with its notable advantages, there are serious disadvantages to be considered.

Pros of Waterjet Cutting Machine

A water jet cutting machine is a qualified use of “green technology”. These machines are not known to produce any byproducts or hazardous wastes that can put the environment in harm’s way. The small kerf is also substantial in such a way that it promotes scrap metal recyclability. Its close-looped system allows for minimal use of water.  

Cuts through almost any material imaginable.  A water jet cutter can through almost every tough object there is, from metals to objects with an uneven or reflective surface, bullet-proof glass down to the stone.  

Absence of  Heat – Water jet cutters do not get dull or overheat due to the absence of friction. So no amount of heat will be generated in the areas adjacent to the cutting space. This means to say that those areas will remain intact and uncompromised all throughout and after the process

Extremely Accurate – Waterjet cutting machines can easily and seamlessly cut out complex 3D shapes with an accuracy level of at least 0.13 mm.  

Cons of Waterjet Cutters

Longer Cutting Time – While it is true that these tools can manage to cut through almost every imaginable tough object, cutting time usually takes much longer than traditional means. More time cutting literally translates into less output for your company, every single time.

Starting Costs – Compared to a plasma cutter, a waterjet cutting method may come a bit more expensive. Finding and putting into account the use of abrasive materials like granite will help increase this cutter’s efficacy, yet can be very costly.

Orifice Failure – A substandard waterjet orifices are likely to break down easily and in the process of doing so would just disrupt cutting. This signifies lost productivity and wasted time and resources for your company.
