For years, the stone industry has been one of the sectors where not only the durability of the material matters, but above all, the perfect precision of workmanship. Today, customers expect custom-shaped kitchen countertops, elegant staircases, facade elements, fireplaces, and decorative mosaics made of granite, marble, or quartzite. As market demands grow, production technologies are also evolving. One such technology is waterjet, a modern method of cutting with water under very high pressure.

This technology has revolutionized the way natural stone elements are manufactured. It allows for the processing of extremely hard, brittle, and expensive materials with the highest precision, without the risk of damaging them. It’s no wonder, then, that more and more stoneworking shops are investing in their own waterjet cutting machines instead of outsourcing the work to subcontractors.

As a manufacturer of CNC machines, we’ve observed that interest in this technology is constantly growing. Users are increasingly entering search terms such as “waterjet,” waterjet cutting machine, waterjet cutter, stone cutting, granite waterjet cutting, waterjet price, or tile waterjet cutting. This means that business owners are looking for solutions that allow them to increase production efficiency, reduce material waste, and at the same time offer customerseven higher quality workmanship.

Why is waterjet technology gaining ground in the stone industry?

Just a dozen or so years ago, most facilities primarily used bridge saws and traditional diamond-blade machines. These solutions are still in use, but they have their limitations. Cutting complex shapes is time-consuming, and with delicatematerials, there is a risk of chipping or cracking.

Modern waterjet technology eliminates most of these problems. The cutting process uses a very thin stream of water under pressure reaching up to 6,000 bar. An abrasive is added to the stream, which enables effective cutting of extremely hard materials.

The greatest advantage of this technology is that the material being cut is not exposed to high temperatures. The process is a cold one, so there is no heat-affected zone characteristic of other machining methods. The stone retains its mechanical properties, and the edges remain perfectly smooth.

How does a waterjet cutting machine work?

A modern waterjet cutting machine is an advanced CNC device consisting of many interconnected components. The most important element is the high-pressure system responsible for generating the water jet. Next, a special nozzle forms a very fine jet, which, when an abrasive is added, becomes an extremely effective cutting tool.

The entire process is computer-controlled. The operator prepares the design in a CAD/CAM program, and the machine automatically follows the programmed path. This makes it possible to create both simple lines and highly complex patterns that would be practically impossible to produce by hand.

In modern solutions, the quality of components is also of great importance. A properly selected water jet nozzle, an efficient high-pressure system, precise linear guides, and a stable machine design determine the final cut quality.

What materials can be processed using the waterjet method?

One of the greatest advantages of this technology is its versatility. A professional waterjet cutter can process many more materials than just natural stone.

The most common applications are:

• waterjet cutting of granite,
• marble cutting,
• cutting conglomerates,
• cutting quartz sintered stone,
• natural stone cutting,
• waterjet tile cutting,
• cutting large-format porcelain tiles,
• glass,
• aluminum,
• stainless steel,
• brass,
• titanium,
• composites,
• plastics.

It is precisely this versatility that allows a single waterjet cutting machine to serve several different production departments. For the company, this means greater flexibility, the ability to take on new orders, and a faster return on investment.

Waterjet cutting of granite - the highest quality without compromise

Granite has long been one of the most popular materials used by stonework shops. Its exceptional durability, abrasion resistance, and elegant appearance make it ideal for kitchen countertops, stairs, window sills, flooring, and facade elements.

At the same time, it is an exceptionally demanding material to work with. Traditional cutting methods often cause micro-damage or require additional edge grinding. With waterjet technology, this problem is virtually non-existent. A waterjet stream with an abrasive cuts through the material with extreme precision, preserving the surface’s aesthetic appeal and minimizing waste.

This makes it possible to produce even highly complex decorative elements, holes for fixtures, or precise mosaics while maintaining perfect repeatability.

Why does Waterjet outperform traditional cutting methods?

Stone processing plants are increasingly faced with the choice of a technology that will ensure the highest quality of processing while reducing production costs. In practice, three solutions are most commonly compared: traditional hand saws, diamond saws, and waterjet cutting.

Each of these methods has its own applications, but when it comes to natural stone and ceramic materials, waterjet cutting offers the greatest versatility.

The most important advantage of waterjet technology is that it does not expose the material being cut to heat. During the process, there is no burning, discoloration, or stress that could weaken the stone’s structure. This is particularly important when processing marble, granite, and quartz composites.

Additionally, a modern waterjet cutter allows for the creation of very small radii, precise holes, and complex contours without the need for additional tools.

Laser cutting of ceramic tiles or waterjet cutting?

Many customers search for “laser cutting of ceramic tiles,” assuming that a laser is the best solution for any material.

In practice, however, the situation is quite different.

Laser technology works great for processing thin sheet metal or plastics, but ceramics and stone are much more demanding materials. High temperatures can lead to stress and microcracks, especially in the case of expensive large-format tiles. Therefore, the combination of laser and tiles is not the best choice.

That is why professional facilities much more often opt for waterjet cutting of tiles. The water jet does not heat the material, so even very thin pieces retain their strength.

This technology enables the following:

• holes for bathroom faucets,
• decorative elements,
• mosaics,
• trim,
• complex architectural patterns,
• large-format porcelain tile elements.

It’s no wonder that the term “waterjet tile cutting” is gaining more and more popularity every year.

What determines the price of waterjet cutting?

One of the most frequently searched terms is “waterjet price.” However, it’s important to remember that there is no single, universal rate for this service.

Many factors influence the cost, including:

• the type of material,
• stone thickness,
• cutting line length,
• number of holes,
• project complexity,
• machine operating time,
• abrasive consumption,
• accuracy requirements.

The situation is similar for search queries such as “waterjet tile cutting price.” Producing simple shapes will be significantly cheaper than creating a decorative mosaic consisting of several hundred pieces.

For stoneworking shops, purchasing their own waterjet cutting machine means being able to complete such orders in-house and become independent of external service providers.

Key components of every waterjet cutting machine

The quality of the cut is determined not only by the machine’s design but also by all the components responsible for generating and guiding the cutting jet.

The most important of these are:

• the high-pressure system,
• cutting head,
• water nozzle,
• abrasive feed system,
• linear guides,
• servo drives,
• CNC control,
• work table.

The nozzle, which is responsible for properly shaping the water jet, is particularly important. Even slight wear on this component can degrade edge quality and increase abrasive consumption.

Professional machine manufacturers design their equipment so that replacing consumable parts is quick and does not cause long production downtimes.

The Importance of the High-Pressure System

The heart of every waterjet cutter is the high-pressure pump. It is responsible for generating the pressure necessary to effectively cut stone. Various design solutions are available on the market. Depending on the application, modern systems known as "water systems" are used, which ensure stable operation and high efficiency even during multi-shift production. Some systems also use a gravity pump to support specific technological processes related to fluid circulation.

A properly selected hydraulic system affects:

• process stability,
• component service life,
• cutting accuracy,
• lower operating costs,
• greater reliability of the entire system.

Does the machine brand matter?

Before purchasing a machine, many business owners compare solutions from different manufacturers. These are well-known brands present in the waterjet cutting market, but the manufacturer’s name alone should not be the sole selection criterion.

The following factors are far more important:

• structural rigidity,
• positioning accuracy,
• guide quality,
• drives used,
• CNC software,
• availability of replacement parts,
• service response time,
• machine expandability,
• operating costs.

As a manufacturer of CNC machines, we know that today’s users expect, above all, reliability, ease of use, and low operating costs. These are the factors that have the greatest impact on the return on investment.
