Ceratizit has introduced the HyproJET waterjet nozzle portfolio.
The way waterjet cutting works is as simple as it is effective: the cutting head directs a fine jet of water at high pressure of up to 6,000 bar, a jet diameter of 0.38 to 1.02 millimeters. In this stress-free cutting process, the material particles close to the surface are cut off without any heat being introduced into the material. This process is an optimal solution for temperature-sensitive and thick materials with complex geometries.
“We developed our HyproJET range with three standard water jet nozzles to meet these needs: narrow hole tolerances, perfect cutting and radial run-out accuracy ensure precise working results,” says Mesut Goksu, segment account manager at Ceratizit. The HyproJET X6 offers an improved flow of abrasive material and air in the nozzle and has a special design for cutting extremely difficult materials. For standard applications, Ceratizit’s range includes the HyproJET P6, which the company says offers an optimal price-performance ratio, while the S3 standard water jet nozzle is the economy-grade entrant. All nozzles are suitable for modern cutting head systems and support automatic centring during assembly.
For some materials to be machined, water alone is not sufficient as a cutting material. The system then mixes an abrasive, such as garnet or corundum, into the water jet. Particularly with demanding materials such as steel, stone, glass, or composites, abrasives are very efficient helpers.
But as much as they support the cutting process, they are not without disadvantages, explains Mathieu Schellenberger, Ceratizit project manager in product development: “They put a lot of strain on the focusing tubes due to erosion. Therefore, when redesigning the HyproJET products, we further improved the wear protection.”
For this purpose, special carbide grades were used, which add endurance to the lineup of HyproJET nozzles, including at pressures of up to 6,000 bar, while maintaining cut quality.
Ceratizit has also changed a few things in terms of packaging the HypoJET nozzles. For example, the company relies on plastic sleeves that optimally protect the waterjet nozzles, but at the same time are highly sustainable,, being made of 100 percent recycled plastic – the so-called PCR plastic (Post Consumer Recycled) – which reduces CO2 emissions by at least 60 percent compared to conventionally produced plastic.
Commenting on the response the new nozzles received when tested by waterjet experts prior to full product release, Mesut Goksu said “The reactions exceeded our expectations. Because when we hear that even experienced professionals rave about the service life and cutting qualities of the HyproJET X6, we have achieved our goal which is to develop a product that makes daily work more efficient and, at the same time, meets the highest quality standards.”
