How Does Water Jet Cutting Marble Work?

Water jet cutting is an innovative and highly efficient method for cutting marble and various other materials. This cutting-edge technique involves a two-phase process that utilizes an ultra-high-pressure pump and a focused water stream to achieve remarkable results. Here are the intricacies of water jet cutting marble:

Phase 1: Pressurizing the Water

An ultra-high-pressure pump, also known as an electric servo pump, provides the energy necessary for cutting.

This pump pressurizes ordinary tap water to pressures exceeding 40,000 pounds per square inch (2760 bar). This immense pressure is essential for the successful execution of water jet cutting.

Phase 2: Focusing on the Water Stream

Once the water is pressurized, it is directed through a tiny precious stone hole, which focuses the stream of water. Depending on the application and desired results, the water stream can flow at speeds up to 2.5 times the rate of sound.

This high-speed flow of water creates an intense cutting stream capable of slicing through marble with precision and accuracy.

Water-Only vs. Abrasive Jets

Water jet cutting can be performed using either water-only jets or abrasive jets. In water-only cutting, the highly pressurized water stream cuts through the marble cleanly and precisely. This method is often preferred when a smooth finish is desired without any additional texture.

On the other hand, abrasive jets utilize the addition of abrasive garnet to the water stream. The abrasive mix chamber, located in the cutting head body, is where the garnet is introduced.

This mixture creates a coherent and highly intense abrasive jet stream, which is particularly useful for abrasive cutting applications. The abrasive garnet aids in cutting through more rigid materials, such as thicker marble slabs or other hard substances.
