How does a water jet cutting machine work?

Waterjet cutting is simply an accelerated erosion process within a selected material. Highly pressurised water is fired through a ruby or diamond nozzle into a mixing chamber. This pressure creates a vacuum and draws garnet sand into the stream where it is then fired at the object in place for cutting.

What is water jet cutting in manufacturing?

Water jet cutting is a manufacturing process that uses high pressure jets of water provided by pressurizing pumps that deliver a supersonic stream of water to cut and shape various types of materials. The water in water jet cutting is pressurized to 392 MPa and projected using a small precision nozzle.

How does a waterjet pump work?

Ultra-high pressure water is fired through a ruby or diamond orifice into a “mixing chamber” which creates a vacuum and draws garnet sand into the water stream. This means waterjet is an extremely powerful and versatile cutting tool, which is used globally for a wide range of waterjet cutting applications.

What is water jet cutting used for?

Waterjet cutting is a cold cutting process that eliminates slag deformation and dross waste – unfortunate effects found in plasma and laser cutting processes. Additionally, both the garnet used in abrasive cutting as well as the water are recyclable.

What is the pressure of water jet cutter?

between 50,000 and 60,000 PSI
Typical waterjet cutting pressure is between 50,000 and 60,000 PSI. Many newer systems are pressurized up to 90,000 PSI. The water at this pressure is then released through a small orifice machined into a diamond or saphire, usually in the range of 5 to 15 thousandths of an inch diameter.

How do water jets cut metal?

By Jessminder Kaur. The key to cutting metal with water is to keep the spray coherent. Waterjets are able to cut because the spray is channelled through a very narrow jewelled nozzle at very high pressure so the spray remains coherent. A waterjet never gets dull and it cannot overheat, unlike metal cutters.

What pressure is water jet cutting?

Cutting with a water jet is a method of engineering for cutting objects using the energy from high speed, high density, ultra-high pressure water. The water is pressurized to a maximum 392 MPa (approximately 4,000 atmospheres) and projected from a small-bore nozzle (Φ0. 1 mm).

What kind of pump is used for water jet cutting?

Two different types of pumps are used in waterjet cutting: intensifier pumps and direct drive pumps. Intensifier pumps use hydraulic oil to push a piston connected to a ceramic plunger, which in turn pushes against the water.

What kind of pump is used for water jet?

There are two types of pumps used today in waterjet cutting: the linear intensifier pump and the rotary direct drive pump. Today, both intensifier and direct drive pumps are capable of reliably delivering ultrahigh-pressure water, and both are successfully used in industry.

What is the type of water jet?

There are two types of waterjet: pure and abrasive. Combined, these two technologies can cut virtually any material, any shape, at any thickness.

What is CNC water jet cutting machine?

A CNC water jet is an industrial tool that uses a high-pressure water jet to cut various materials. It can use water alone to cut soft materials like wood and rubber, or the water can be mixed with an abrasive substance (like garnet or aluminum oxide) to cut harder materials.

How thick can a water jet cutter cut?

12 inches
How thick can an abrasive waterjet cut? The high-level answer is that abrasive waterjets can cut through 12 inches of most materials. Many users report cutting material even thicker than that. Most abrasive waterjet cutting, however, is done in material that is 3 inches thick or less.
