A. Working Principle

The core principle behind the Gantry abrasive waterjet cutting machine lies in the fusion of high-pressure water flow and abrasive cutting technology, executed within a gantry-style structure to achieve precise three-dimensional cutting within the workspace. The operational sequence commences with pressurizing water via a high-pressure water pump, forming a high-pressure water flow. Subsequently, abrasives are introduced into the water flow, creating a hybrid mixture. This blended flow, propelled through specially designed nozzles, is jetted onto the surface of the material awaiting cutting at exceptionally high speeds. The high-velocity water jet, combined with abrasive particles, effortlessly penetrates and cuts materials of varying hardnesses and thicknesses.

Its operational methodology predominantly comprises several key steps:

1. Generation of High-Pressure Water Flow

The workflow initiates by pressurizing water to extreme pressures via a high-pressure water pump. This highly pressurized water is primed for cutting applications.

2. Injection of Abrasives

Within the high-pressure water flow, abrasives (typically silicon sand or other high-hardness materials) are introduced, creating a hybrid fluid. The inclusion of these abrasives enhances the cutting capacity of the water flow, rendering it more adept at cutting materials of diverse hardnesses and thicknesses.

3. Jetting Outflow

The blended flow, directed through specially designed nozzles, is expelled onto the surface of the material awaiting cutting at an extraordinary velocity and pressure. The high-speed jet of water, accompanied by abrasives, akin to the force of a high-velocity storm, effectively pierces and cuts through various materials.

4. Cutting Process

Upon contact with the material, the high-pressure jet of water and abrasives instantaneously generate high-speed abrasion and impact, leading to the separation and cutting of the material. In this process, the hardness of the abrasives and the high-pressure of the water flow collaboratively achieve efficient cutting.

5. Precision Cutting and Control

The Gantry abrasive waterjet cutting machine employs a computer control system that precisely regulates the water flow and cutting process, facilitating high accuracy and rapid cutting. This precision control enables the machine to execute intricate cutting patterns and curves.
