Waterjet cutting technology has long been considered one of the most precise methods of material processing, yet it is still often associated with low productivity. Is this justified? In this article, we explain what really determines waterjet cutting speed and show how the proper selection of process parameters allows you to combine high precision with efficient production. We discuss the impact of water pressure, the high-pressure pump, the nozzle, the abrasive, feed rate, and cut quality levels Q1–Q5. We also present applications of modern CNC waterjet cutting machines and explain how to optimize the process based on research findings and technical literature.

Waterjet technology is one of the most precise solutions used in modern stoneworking. Learn how a waterjet cutting machine works, what benefits it offers for cutting stone, granite, marble, and porcelain tile, and why a CNC waterjet cutter helps increase production efficiency and reduce material waste. Discover the advantages of this technology, its applications, and tips for choosing the right stone processing system.

This article explains the principles of waterjet cutting, its key advantages, and its wide range of industrial applications. It also presents the machine’s core components, including the cutting head, high-performance high-pressure pumps, and an innovative self-cleaning water table that improves productivity while reducing operating costs. A comprehensive source of knowledge on waterjet cutting and advanced material processing systems, ensuring exceptional precision, quality, and repeatability in manufacturing.

In the CNC industry, the value of an investment is increasingly determined not only by machine specifications, but above all by after-sales service, spare parts availability, and fast technical support. These factors have a real impact on minimizing downtime and ensuring production stability.

NIST research and industrial analyses show that inefficient maintenance generates significant losses, while a predictive approach can substantially reduce failures. As a result, CNC machine manufacturers are now becoming partners in the production process rather than just equipment suppliers.

Eckert emphasizes the importance of a comprehensive approach that integrates technology, service, and support - together building a competitive advantage in modern industry.

Modern Automation in Plasma and Oxy-Fuel Cutting – in this article, we present the Szafir CNC cutting machine equipped with the Automatic Torch Head Changer system, developed in cooperation with Kjellberg. The solution automatically replaces worn torch consumables, reduces maintenance time, improves operator safety, and optimizes production processes. The result is increased productivity, lower operating costs, and consistently high cutting quality.

Modern industrial production today demands not only speed, but above all stability, precision and full control over the process. That's why modern plasma cutting technologies are evolving toward greater automation, predictability and integration with digital production environments. The iQ-Series from Kjellberg responds to these needs with advanced plasma sources designed for demanding plants, where the highest cutting quality, productivity and readiness for the challenges of Industry 4.0 matter.

Opal Waterjet by Eckert is an advanced CNC waterjet cutting machine for precision cutting of stone and many other materials such as metal, glass, ceramics and plastics. Waterjet technology uses a jet of water at very high pressure, often with garnet abrasive, which allows it to cut hard materials without the effects of temperature and thermal deformation.

The machine offers high accuracy, repeatability and the ability to complete complex projects thanks to CNC control and 3- and 5-axis heads. The waterjet is used in masonry, construction, automotive and industrial applications, providing high edge quality and efficient machining without the need for additional finishing.

Plasma, oxygen, waterjet or laser - which CNC cutting technology wins in 2026? The answer is not clear-cut, as each method is designed for different industrial applications. Plasma and oxygen dominate heavy manufacturing and large material thicknesses, waterjet provides no thermal impact and wide material versatility, and laser sets the standard in precision and automation. In practice, the choice depends on the material, expected edge quality, process speed and production costs. More and more plants today are opting for a hybrid model, combining several technologies in a single CNC environment. Find out which method best meets the demands of modern manufacturing.

Zircon Extreme is a solution created for heavy industry, where productivity, precision and reliability matter. Plasma and plasma-oxygen cutting technology enables fast and accurate processing of sheet metal and large steel parts, while supporting the automation of production processes.

Increasing market demands mean that CNC cutting machines of this type provide a stable process, high quality and efficiency even in intensive operation and over a wide range of material thicknesses.

Three-dimensional (3D) laser tube cutting has become one of the most important solutions in modern component machining, enabling fast and highly accurate preparation of parts for further assembly. Today's industrial CNC machines make it possible to automatically machine pipes and profiles, obtaining repeatable parts without the need for manual adjustment of parts. Automating production processes significantly reduces project lead times and reduces material waste. As a result, companies can increase productivity while improving the quality of their designs, regardless of the scale of production.

Optimizing production in a modern plant is not just about increasing productivity. Maintaining work continuity and reducing the risk of unplanned downtime is key. In the case of CNC cutting machines, this means consciously managing their operation - from ongoing condition monitoring to preventive measures to efficient service. These are the elements that determine process stability and production predictability. Find out how to put these areas in order in practice and effectively reduce CNC machine downtime.

Precision welding requires perfectly prepared parts, which is why more and more technologies are already being used at the machining stage to produce edges ready for joining. Modern 3D cutting and plasma beveling reduce material preparation time and reduce the need for manual processing before welding. This results in reproducible part quality, better weld parameters and less consumption of additional materials. A well-prepared workpiece goes directly to further assembly, which in serial production translates into real savings in time and cost, and reduces the risk of manufacturing errors.
