Precision Waterjet Cutting: Achieve Accurate Parts with Tight Tolerances
Introduction
Precision waterjet cutting is a process that uses an ultra-high pressure stream of water and abrasive to cut materials of various shapes and sizes. It is a fast and accurate method for producing parts with tight tolerances. The process is ideal for cutting complex shapes and intricate designs in a range of materials including plastics, metals, composites, and many other materials.
What is Precision Waterjet Cutting?
Precision waterjet cutting is a process that utilizes an ultra-high pressure stream of water and abrasive to cut through materials. The process is capable of cutting through a wide variety of materials such as plastics, metals, composites, and many other materials. The process is highly accurate and can be used to cut complex shapes and intricate designs with tight tolerances.
The process begins with the material to be cut being placed on a precision table. The table is then moved to the cutting zone where it is positioned underneath the waterjet nozzle. The nozzle is connected to a high-pressure pump that is capable of producing pressures up to 60,000 psi (4,137 bar). Abrasives are added to the water stream which creates a cutting force strong enough to penetrate the material. As the material is cut, the table is moved in a precise manner to ensure the desired shape and size is achieved.
Advantages of Precision Waterjet Cutting
Precision waterjet cutting has several advantages over traditional cutting processes. These advantages include:
- Highly accurate cuts with tight tolerances
- Able to cut complex shapes and intricate designs
- Can be used to cut a wide range of materials
- No heat affected zone (HAZ)
- No tooling costs
- Cleaner cuts and edges
- No burrs or sharp edges
- Cost efficient compared to traditional methods
Process Overview
How Does Precision Waterjet Cutting Work?
The process of precision waterjet cutting begins with the material being placed on a precision table. The table is then moved to the cutting zone where it is positioned underneath the waterjet nozzle. The nozzle is connected to a high-pressure pump that is capable of producing pressures up to 60,000 psi (4,137 bar). Abrasives are added to the water stream which creates a cutting force strong enough to penetrate the material. As the material is cut, the table is moved in a precise manner to ensure the desired shape and size is achieved.
The cutting process is computer-controlled, allowing for high levels of accuracy and repeatability. This ensures the parts produced are consistent and of the highest quality. The process also allows for the use of multiple cutting heads, which increases efficiency and throughput.
