Hopefully, by reading these tips, you will have a deeper understanding of the waterjet process. Some of these techniques are easy to understand, while others can only be mastered through practice.
1. Cut thick material
When cutting materials with a thickness of less than 2.5, the production of medium-sized or large-sized cutting heads is not high. If needed, use a combination of small parameters and consider using multi-headed cuts to increase yield.
2. When the cutting meets the air seam
Avoid cutting gas gaps larger than 0.5mm. The nozzle has a tendency to diverge in the air gap, so it will roughen the surface when cutting the lower layer. When stacking cuts, keep the sheets neatly stacked together.
3. Smaller abrasive mesh
A smaller abrasive mesh (120 mesh or less) will slightly reduce the speed, but it will produce a smoother surface (compared to 80 or 50 mesh).
4. Production costs are calculated per inch
The cost of production is calculated per inch instead of hourly. The cost of running an abrasive waterjet per hour is not very important. The most important thing is how many parts you can produce in a given period of time. Some users mistakenly believe that operating costs can be minimized by reducing the jet rate. Although abrasives account for the operating costs of the Sands Waterjet 2/3, you must quickly produce parts to offset the consumption of recurring expenses (labour, facilities, rental costs). Open all horsepower and use the highest sand injection rate to maximize the cutting speed.
5. Increase and decrease the water pressure through the controller
If you regularly cut composites, glass, and stone, make sure the system has the ability to increase or decrease water pressure through the controller. At the same time, you should also study vacuum assisted technology or other technologies to increase the success rate of puncturing brittle or laminated materials.
6. Designed specifically for the process control system
Control systems designed specifically for the process are usually more efficient and easier to use than general multi-process control.
