Advantages of WaterJet Cutting Machine

Waterjet cutting is a precision cold cutting method that uses ultra-high pressure water. In recent years, waterjet cutting has become one of the fastest growing major cutting processes in the world due to its versatility, ease of operation and high precision. In modern manufacturing and engineering fields, from aerospace, automotive manufacturing to architectural decoration and oil and gas, waterjet cutting is increasingly used. In this article, we will explain the advantages of waterjet cutting from a professional perspective, so that you can have a clearer understanding of waterjet cutting.

Core Advantages Analysis
No heat-affected zone, a new way to protect materials
Water Jet cutting is a typical cold cutting process. High-speed water flow takes away the heat generated during cutting and does not cause thermal effects on the material. Therefore, when cutting heat-sensitive materials such as high-temperature alloys and composite materials, water jet cutting will not cause material strength loss or thermal deformation. Compared with laser, plasma or flame cutting that rely on high temperatures, water jet cutting has a negligible effect on material properties and better maintains the mechanical and metallurgical properties of the raw materials.
A variety of materials can be cut
Water jet cutting is applicable to a wide range of materials, and can process almost all solid materials, including metals (such as steel, stainless steel, aluminum, titanium, copper), composite materials, plastics, glass, ceramics, stone, etc. Unlike laser cutting, which is difficult to cut reflective or heat-absorbing materials, water jet cutting does not need to consider some restrictions of materials. A water jet device can quickly switch cutting tasks of different materials, whether it is a plate as thin as a few millimeters or a large plate as thick as tens of centimeters.

High precision and clean edges
Thanks to the stability of the machine tool and the controllability of the cutting flow, the accuracy of water jet cutting can usually reach 0.1 mm. The cutting process is stable and can achieve extremely fine geometric shape processing. The edges after cutting are smooth and burr-free. Compared with plasma or flame cutting, water jet cutting has better surface quality and basically does not require subsequent processing, which greatly saves processing process and cost, and directly meets the use requirements of high-precision parts.

No secondary processing is required, saving labor time cost
Another significant advantage of water jet cutting is that subsequent secondary processing is usually not required. Because the cutting surface is flat and smooth, the parts can be used directly after processing. This means that the common deburring, chamfering, polishing or heat treatment processes in traditional cutting methods can be omitted, and assembly or the next process can be directly entered, thereby significantly saving labor and processing time costs.

Energy saving and environmental protection, reducing exhaust gas and dust emissions
The water jet cutting process does not involve combustion or melting, and does not produce toxic smoke, dust or harmful gases. In contrast, laser and plasma cutting are often accompanied by high-temperature smoke emissions. Water jet cutting mainly consumes electricity and a small amount of abrasives. The cutting water can be recycled, and the comprehensive energy consumption is relatively low compared to other machines. Therefore, water jet cutting meets modern energy-saving and environmental protection requirements and is an important part of green manufacturing.

Strong automation compatibility and can be linked with CNC systems
Modern Water Jet Cutting Machines usually use CNC systems, which can be programmed and path planned through CAD/CAM software to achieve fully automated processing. The five-axis water jet system can also perform tilted cutting and process complex curved workpieces. In short, water jet cutting technology adapts to the trend of industrial intelligent manufacturing, is easy to integrate with automation equipment, has good programmability and automation characteristics, and is easy to realize unmanned assembly line production.

Application scenario examples
Water jet cutting technology is widely used in many industries, and its advantages are fully reflected in practice. For example:
Aerospace: used to cut key components such as titanium alloys, high-temperature alloys and carbon fiber composite materials to ensure intact structural performance;
Automobile manufacturing: used to cut body sheet metal, engine parts, mold linings, etc., to achieve high precision and high consistency;
Architectural decoration: used for special-shaped cutting of decorative materials such as granite, marble, and glass, and can process various complex patterns without cracks;
Oil, gas and energy: In the manufacture of large equipment such as pipelines, pressure vessels, and heat exchangers, water jets can effectively cut thick steel plates and special-shaped parts to avoid the risk of thermal deformation;
Other fields: Water jets are also used in military industry, transportation, art and crafts, and other industries, such as gun barrel cutting, traffic sign stamping, sculpture processing, etc.
