Cantilever Abrasive Waterjet Cutting Machine

Cantilever Abrasive Waterjet Cutting Machine" is an advanced industrial processing equipment used for cutting various materials by employing a mixture of high-pressure water flow and abrasive particles. Unlike the gantry-style structure, the design of the cantilever machine focuses more on its working platform structure and flexibility.

A.Principle of Operation

The cantilever abrasive waterjet cutting machine utilizes high-pressure water flow combined with an abrasive mixture for cutting purposes. At the start of the operation, a high-pressure pump pressurizes water to an extremely high level, which is then conveyed through specialized pipelines to the cutting head. In proximity to the cutting head, abrasive materials (often higher hardness substances like silicon sand) are introduced into the high-pressure water flow, forming a mixture. This combined flow is directed through a nozzle onto the material being processed, where the abrasive particles, propelled by the high-speed water flow, induce cutting action upon impact.

1. High-pressure Water Pump: At the beginning of the operation, the high-pressure water pump pressurizes water to an extremely high pressure, typically above 40,000 PSI.

2. Abrasive Injection: Abrasive materials (often silicon sand, among others) are introduced into the water flow, creating a mixed flow. These abrasive particles, when mixed with the high-pressure water flow through the nozzle, create a forceful jet.

3. Jet Cutting: The mixed flow passes through the nozzle, being forcefully sprayed onto the surface of the material to be cut. The high-speed water flow carries abrasive particles that, through impact and abrasion, can penetrate and cut materials of various hardnesses and thicknesses.

4. Worktable Movement: The worktable, designed with a cantilever structure, is supported on one side while the other remains suspended, allowing movement within a confined workspace, enabling a more precise and flexible cutting process.

B.Structural Characteristics

The structural features of the cantilever abrasive waterjet cutting machine primarily lie in its worktable and machine architecture, providing specific advantages and flexibility during the machining process.

1. Single-sided Support： One side of the worktable is fixedly supported, while the other side remains suspended, allowing the worktable to move freely within a limited space.

2. Flexibility： This design enhances the machine's flexibility, enabling it to accommodate diverse machining requirements for varying sizes and shapes of workpieces.

3. Mechanical Cantilever： It commonly employs a mechanical arm or support structure to ensure the stability of the worktable, offering necessary support and mobility.

4. Control System： Equipped with a precision control system, capable of accurately controlling the movement of the worktable and the cutting process, ensuring cutting quality and precision.

Cutting Nozzle and Water Flow Control System：

1. Precision Nozzle： It features specially designed cutting nozzles capable of jetting high-speed mixed water streams carrying abrasive particles for cutting purposes.

2. Flow Rate and Pressure Control： The cantilever abrasive waterjet cutting machine is equipped with a highly controllable flow rate and pressure control system, ensuring stability and consistency of the jet stream.

Support Frame and Mechanical Structure：

3. Stability： The machine frame is typically designed for structural stability, offering sufficient support to ensure stability during the cutting process.

4. Adjustability： Some models may feature adjustable support structures to accommodate different height and angle cutting requirements.

These structural characteristics enable the cantilever abrasive waterjet cutting machine to fulfill high-precision and high-efficiency cutting demands within relatively confined workspaces. Its flexible worktable design and precise control system offer advantages in machining intricate components.
