Waterjet cutting - Questions & Answers

Briefly, what is waterjet cutting?

Waterjet cutting is the most versatile and quality technology for cutting a wide range of raw materials. The technology is based on a stream of water forced through a tiny orifice at high pressure and supersonic speed. The water hits the specific point in the material and creates erosion that results in a clean and accurate cut.

What are the main advantages of waterjet cutting?

Waterjet cutting is a technology that offers a wide range of advantages. The main advantages are a cold cutting process, suitability for all industrial raw materials, high level accuracy, materials of different thicknesses, environmentally friendly, does not require secondary finishing, can cut complex geometric shapes, and 2D and 3D cutting. For additional information about the advantages read here.

What raw materials can be cut using waterjet cutting?

Waterjet cutting can cut virtually all raw materials used in a wide range of industries, including metals, rocks, ceramic, rubber, foam, glass, composite materials and synthetic materials. For additional information about the raw materials read here.

What size raw materials can be cut?

Ecojet can waterjet cut raw material of up to 2×4 meters and up to 150 mm thickness and more (depending on the type of material and its density).

What accuracy levels are achieved with waterjet cutting?

Waterjet cutting is a technology with tolerance accuracy of 0.04 mm.

Why is waterjet cutting considered an economical technology?

Waterjet cutting is considered an economical technology for several reasons. First, the edges of the cut material are not burned or harmed during the cutting process and therefore there is no need for supplementary finishing. Furthermore waterjet cutting machines can carry out projects that require cutting several layers, and in many cases the process is faster compared to other solutions (so that the customer saves both valuable time and resources). Also, waterjet cutting enables maximum use of the raw material, with minimum scrap owing to the close nesting.

For which industries is waterjet cutting suitable?

Just as waterjet cutting is suitable for cutting virtually all raw materials, thus the technology is relevant for every industrial sector. Among other things, waterjet cutting is used in plants and companies in industries such as defense, medicine, high tech, flooring, architecture, glass, signage, rock, optical and automotive. Read here for additional information about the relevant industries for waterjet cutting.

What is the main advantage of waterjet cutting and what is cold cutting?

Waterjet cutting is a cold cutting technology. This is a significant advantage that provides a solution for cutting soft raw materials or raw materials sensitive to high temperatures. These raw materials are cut by a waterjet without the process harming the original properties of the raw material.

Is waterjet cutting an “environmentally friendly” technology?

Waterjet cutting is considered a “green” and environmentally friendly technology for several reasons. First, the water used for cutting is recyclable for multiple use. Furthermore, the cutting process is not accompanied by the emission of toxic gases and vapors, protecting the environment as well as employee health.

What is the difference between cutting that only uses water (pure waterjet) and cutting with water and an abrasive (abrasive waterjet)?

Waterjet cutting can be based solely on water (pure waterjet) or on water combined with an eroding abrasive (abrasive waterjet). The former solution is usually suitable for cutting soft raw materials, while the latter solution (that includes water as well as sand combined with quartz) is usually intended for cutting hard raw materials.

What files do you need to send for waterjet cutting?

Waterjet cutting is a simple and easy technology to operate. The process is conducted based on a vector graphics drawing created using CAD software and can use DXF, DWG, IGS and other file formats. Furthermore, Ecojet can carry out projects based on drawings and image files which we convert into CAD files, subject to the customer’s approval. Read here about the file uploading process.
