Cold Cutting, No Heat-Affected Zone

Thick Plates, Complex Profiles
Waterjet cutting is a sheet metal fabrication process that uses a high-pressure stream of water to cut materials into precise shapes and profiles. Abrasive particles can be added to the water stream when cutting harder materials such as metals.
Unlike thermal cutting processes, waterjet cutting does not rely on a heat source to melt or burn through the material.
Waterjet cutting creates parts by directing a high-pressure water stream through a small cutting nozzle along programmed toolpaths. Here are the processes of waterjet cutting at 3DSPRO:
Import the CAD file and review the part geometry.
Select the appropriate material and sheet thickness.
Determine the suitable waterjet cutting method and abrasive requirements.
Generate and optimize cutting paths.
Position and secure the sheet metal.
Waterjet cutting machine operating.
Remove the cut parts from the cutting bed.
Inspect and clean the cut edges and surfaces.
Deburring or other secondary operations if required.
Bending, welding, or surface finishing (optional).
Quality inspection.
Packing and shipping.
1. Produces complex profiles without significant heat input.
2. Minimizes heat-affected zones compared with thermal cutting methods.
3. Can process a wide range of metals and material thicknesses.
4. Suitable for intricate contours, openings, slots, and custom profiles.
5. Does not require dedicated cutting dies, making it suitable for prototypes and custom parts.
1. Cutting speeds can be slower than some thermal cutting methods for certain applications.
2. Abrasive waterjet cutting consumes abrasive media during operation.
3. Equipment and operating costs can be higher for some projects.
4. The cutting process uses significant amounts of water and requires appropriate waste management.
