Benefits of Water Jet Cutting

Take a few minutes to learn about the benefits of water jet cutting and compare it with traditional cutting methods. Actually, the biggest advantages of water jet cutting is its cold cutting quality. Its cutting feature allows materials to be cut which may be burned, melted, or cracked if we use other cutting methods. Some cutting processes may cause surface hardening, warping or even emission of hazardous gas. In contrast, using waterjet machine to process materials don’t need to worry about such undesirable results.

Benefits of Water Jet Cutting

  • Cold cutting – no heat affected zones, no hardening
  • Omni-directional cutting – ability to cut in any direction
  • Perforates most materials without starting holes
  • Cuts virtually any material
  • Net-shape or near-net-shape parts (no secondary processing required in many applications)
  • Minimal fixturing required
  • Environmentally friendly
  • Reduces dust and hazardous gases
  • Does not workload material – stress-free cutting
  • Flexible machine integration
  • Saves raw materials (small cutting kerf width, nesting capabilities)
  • Faster than many conventional cutting tools
  • This opens the door to a variety of Waterjet Applications across different industries including
  • Glass, Stone, Metals to Aerospace and Textiles.

Another major advantage of water jet cutting than other cutting methods it can cut different materials even in a same content. Water jet can cut on a microscopic level and avoid leaving any edges or burrs. This produces excellent edge quality, which in many cases eliminates the need for secondary finishing processes.

Advantages of water jet cutting

Water jet cutting is especially conducive to cutting complex shapes. Material can be cut into almost any shape. No matter sharp corners, bevels, pierce hole or even with the minimum inner radius and shapes are all possible. Cutting overlay, nested and optimized material can be reduced the cutting time significantly .

Waterjet cutting is particularly “friendly” in regard to the environment.

As long as we are not machining a material that is hazardous, the spent abrasive and waste material become suitable for land fill. The garnet abrasive is inert and can be disposed of with our other trash.

If we are machining lots of lead or other hazardous materials, we will still need to dispose of our waste appropriately, and recycle the water. Keep in mind, however, that very little metal is actually removed in the cutting process. This keeps the environmental impact relatively low, even if we do machine the occasional hazardous material.

In most areas, excess water is simply drained to the sewer. In some areas, water treatment may be necessary prior to draining to sewer. In a few areas, a “closed loop” system that recycles the water may be required.

The pumps do use a considerable amount of electricity, though, so there is some additional environmental (and cost) impact due to this.

The amount of material removed by the waterjet stream is typically about 0.02″ (0.5 mm) wide, meaning that very little material is removed. When working with expensive material (such as titanium) or hazardous material (such as lead), this can be a significant benefit. It also means we can get more parts from a given sheet of material.

If using pure water, it is possible to cut textiles, elastomers, non-wovens, thin plastics, food products and many other products. These advantages are other cutting methods cannot compare with.

If using abrasive water jet, even harder materials such as metals, stone, bullet proof glass, ceramics, etc. also can be cut easily.
