Investing in a new production technology with the technology of tomorrow and the price of yesterday

With the water jet cutter of the type Plesio new, a refreshing wind blows through your production plant. The technology of water jet cutting offers you entirely new production possibilities. And all this at a previously unknown, incredibly low-price level. German quality from the brandmanufacturer CNC-STEP.

No distortion due to heat as with lasers

Cut stainless steel sheets and many other heat-sensitive materials free of distortion with the water jet cutter Plesio. This is because it brings no heat in the form of radiation energy (lasers) or friction (during milling) into the material you want to process.

Cut up to 150 mm thick steel parts or other materials

Exact cuts in any material, as well as in steel or stainless steel are the result, on our machines even up to 150 mm thickness. Since we have done experiments with the cutting of a 150 mm high anvil. This was cut through within 29 minutes on a cutting length of about 120 mm. This time could have been reduced because we had achieved a quite good cutting quality and had cut our 60 mm high worktable grid underneath the workpiece smoothly! Therefore, we assume that also 200 mm thick steel can be cut!

To the exact workpiece – without waiting times – independent of the contract cutter!

With the Plesio cutter, you can take the production processes for waterjet cut parts into your own hands and thus no longer be tied to contract cutting companies. Besides, you can work much more cost-effectively in the long term. Of course you also save yourself much trouble if the company working for you does not work correctly according to your quality requirements.

Semi-automatic water level regulation at the push of a button

Cutting with the Plesio always takes place under water to keep the noise level and the degree of contamination of the machine as low as possible. Underwater cutting up to about 60 mm workpiece height can be realized with the machine. You can rise the water level to the corresponding height at the push of a button, controlled by adjustable water level sensors. And it also lowers within a few seconds after the cutting process. Obviously, you can likewise work without the water level regulation. However, you will love this intelligent special function, which we have integrated free of charge.

Brand quality from Germany and Switzerland

The high-quality German and Swiss components used in our cutting system sum up our concept. The entire system is basing on the portal unit “RaptorX-SL”, which we developed 12 years ago. This unit has already proven itself in the industrial sector many times and has been produced by us more than 100 times and sold internationally.

High-pressure pump from HAMMELMANN® Germany / Abrasive system and cutting head from Allfi® Switzerland

The high-pressure pump used by us from the leading German company for high-pressure pumps, company HAMMELMANN®, is not only extremely powerful but also impresses with its extreme ease of maintenance and its very high energy efficiency of up to 96%!

Hydraulic pressure intensifier pump vs mechanical plunger pump

Due to the high maintenance intensity and the low efficiency of only approx. 60% of the pressure intensifier pumps, we have deliberately chosen the much more maintenance-friendly and highly efficient variant of high-pressure pumps. The mechanical plunger pump with an efficiency of up to 96%, whose most essential components function like a system that has been proven a hundred million times over – the combustion engine with the crankshaft.

Good for your energy balance and your wallet: because where 15 kW are added, about 14.4 kW arrive at the cutting nozzle and not only about 9 kW, as is the case with pressure intensifier technology.

3800 bar pressure – a water jet cutter with up to 4.0 L/min flow rate

3800 bar pressure is available at the pump outlet while cutting! We also offer two different drive motor versions, with 15 kW and 30 kW, which guarantee flow rates of 2.0 litres to 4.0 litres per minute at a maximum pressure of 3800 bar! Accordingly, you are equipped for any kind of work in almost all materials, if you wish.

Long warranty period of the high-pressure pump of 24 months on new systems

The warranty period for theHAMMELMANN® high-pressure pump is 24 months after commissioning but after a maximum of 2000 operating hours and max. 18 months after dispatch. This is unique in the high-pressure pump sector. Most companies only offer a maximum “Inclusive warranty period” of 12 months and 1000 hours. Often only a warranty is given on the pump.

Deliberately no bellows over the triple sealed HIWIN linear guides

We have intentionally omitted the bellows above the linear guides. For important reasons: “What I don’t know, I don’t care to know” – you know that, right? Your employees feel the same way if the linear guides under the bellows slowly but surely get dirty and, depending on the linear guide used, may show signs of corrosion due to the continually rising “water vapour”.

No penetration of dirt/abrasive into the carriages

After all, the intrusion of dirt is not an issue, as we use the highest possible sealing for heavy industry for the carriages!

Since we always cut under water, there is almost no splash water and therefore no abrasive flight. If, however, the guides become dirty or otherwise damaged, the employee can always counteract the problem by visual inspection. After the shift, wipe the guides once with a dry cloth – a 5-minute effort – and you are always on the safe side that there will be no problems with your linear guides in the long term.

Pressure test on the Plesio water jet cutter

The purpose of a pressure test is to check whether the performance of the pump used is constant. We have also performed this test on our Plesio water jet cutter.

To do this, insert an analogue pressure gauge between the cutting nozzle and the water pipe and then start the high-pressure pump. The measured values during start, stop and pumping are continuously measured. Only pure water is used for this test. In conclusion, you get a good overview of whether the water pressure of the pump is within limits for the intended use and meets the technical requirements.

Water Jet Cutter – advantages and application possibilities

In many different sectors, including the metal and plastics processing industries, the demand for processing with a water jet cutter is growing steadily. The possibilities of material processing with a computer-controlled water jet cutter are so versatile and far superior to manual processing in terms of precision and speed.

But what exactly is a water jet cutter? Which materials can be processed with such a cutter? And above all: How does such a machine work? In the following, we would like to answer all these questions.

What is a water jet cutter?

First, one must clarify what the term “CNC” means. This abbreviation stands for the English expression “computerized numerical control“. In short, it means that an electronic procedure is used to control the respective CNC machine. This enables the machine operator to quickly and precisely implement even complex contours and shapes in a wide variety of materials.

Like a CNC milling machine, this water jet cutter has at least three axis. The cutting head, which directs the abrasive water jet, is mounted on the Z-axis running horizontally to the work surface. The combination of the conveyor and the high-pressure pump produces a correspondingly strong jet depending on the material. The result is an almost burr-free workpiece.

How does a numerically controlled water jet cutter work?

As already explained, a computer controlls the CNC machines. The produced G-code is read in and processed via an individual control software. This G-code consists of coordinate commands that were previously created with the help of a design software. By standardizing these codes, they can be used on almost all CNC milling machines due to the numerical control software.

Difference between pure water jet cutting and abrasive water jet cutting

Depending on the application or material, you can now choose between pure water jet cutting or abrasive water jet cutting. What does this mean in concrete terms? On the one hand, you cut out with a jet of pure water, which is very popular for softer materials such as foils, rubber or fabrics and is also used in the food industry for cutting vegetables or cakes, tarts and much more.

The garnet sand or corundum “cuts” hard materials

On the other hand, you can add an abrasive in the form of garnet sand or corundum to the water. This produces a corresponding water-abrasive mixture, which is therefore ideal for cutting harder and stronger materials. Most people know corundum as a material for grinding wheels. In the grinding wheel, the corundum particles are firmly bonded by means of a binder and form a solid structure as a unit of thousands of particles bonded together. In waterjet cutting, however, each particle does this job on its own.

Up to 1000 meters per second – A corundum particle on its way to a world record

This corundum is therefore now added to the water jet during water jet cutting shortly before the water emerges. It thus carries out its grinding work on the workpiece to be cut by the corundum particle grinding away the smallest workpiece particles at a world record speed of up to 1000 meters per second. Depending on the feed rate, this also results in the high quality of the cut surface.

Highest efficiency due to perfect combination of abrasive quantity and nozzle diameter

You can make the water jet even more effective by adjusting the water pressure, increasing the abrasive content and adjusting the nozzle diameter. This accelerates the flow rate of the water and the abrasive particles, which results in an increased impact of the jet on the material and thus increasing the cutting force. Of course, you should note that the dosage of garnet sand should be adjusted according to the thickness of the material to be cut.

With the technique of water jet cutting, for example, various materials can be ideally and precisely processed:

natural stone such as granite, marble, sandstone, slate, soapstone
ceramic tiles, flagstones, porcelain stoneware, clay
stainless steel, steel, brass, copper, tool steel
plastics like PTFE, Plexiglas®, polycarbonate
woods like hardwood, beech, spruce, fir, multiplex
glass and many more

You will find the versatile application possibilities with our water jet cutters in this article.

Water Jet Cutter – purchase decision – TIP

If, as a result, you have decided to purchase such a machine, the question arises accordingly: “What should I consider before purchasing a water jet cutter?”

The machine capacity

Consequently, before you send your inquiries to various manufacturers think about your project. For example, you should already have an idea of the approximate size of the materials which you will process. The traverse paths of the machine ultimately limit the size of the material that fits on the working area.

The pump and its performance

It is also extremely important to know which materials to machine, as this also determines the choice of the required pressure performance of the pump. Softer and thinner materials such as rubber, plastic or wood require less power than harder materials such as metals, for example, cast steel or steel. A knowledgeable machine manufacturer is happy to assist you in deciding.

Material to be machined

Furthermore, the torsional rigidity of the entire system is significant concerning the application. With water jet cutters, one can generally say that they should have high torsional stiffness. This is important since the recoil when the waterjet is switched on can sometimes cause a loss of accuracy on the material to be processed in an unstable system.

Accuracy – Set cutting values exactly

You should configure the cutting values of the water jet cutter as ideally as possible for the material you want to process. Because the more precisely the cutting system is adapted to the requirements of the material, the more accurate and clean the cutting results will be.

With these tips, you are well prepared accordingly. You should also consider a possible prior inspection of the machine. In this case, you can also ask the manufacturer or dealer of your choice for a test cut in the material you are using. In this way, you can personally convince yourself of the construction of the machine and the working results.
