Waterjet Cutting Vs. Laser Cutting

Waterjet or laser? Many modern manufacturers are facing unique challenges, including maintaining flexibility while keeping costs low. The waterjet and the laser are both capable of cutting a variety of materials at high speeds. The choice of which one is more accurate, faster, and better for production is determined by each individual’s needs and what will bring value to your specific application.

How does a Waterjet work?

The FlexJet waterjet uses high-pressure water-focused in a minimal point to cut the material in a subtractive manufacturing process. The pressure can be as high as 90,000 pounds per square inch. The water mixes with an abrasive such as garnet, which increases its cutting possibilities. The FlexJet waterjet is also able to achieve taperless cutting in challenging to reach areas. 

Waterjets cut a variety of materials by employing a cool-cutting process that leaves no heat-affected zones. The elimination of using heat means the process can go straight from the waterjet to threading or welding operations without the need to remove any heat-affected material. Which ultimately cuts down on labor and provides a quality product with speed and efficiency. The clean-cut of a waterjet also eliminates the need for grinding or sanding. Lasers and other tools struggle to cut materials with high thermal conductivity (like steel or aluminum) effectively. On the other hand, waterjet machines eradicate any heat-affected zones, leading to microscopic cracks or structural weakness in components.

How does Laser Cutting work?

Cutting with a laser uses a beam by making contact with the material surface. The laser heats it so strongly that it melts or completely vaporizes the material, causing it to separate. Once the laser beam has penetrated the material at one point, the actual cutting process begins. The laser beam path follows the selected geometry or cutting lines and separates the material in the process. A laser cutting machine can also engrave as well as cut using a laser. It will engrave and cut various materials such as plastics, wood, paper, food, fabric, foam, and metal foils up to 0.5 mm. 

In Conclusion

Is FlexJet the best option for every application? It depends on your goals and what material you are machining. When it comes to price, flexibility, and versatility, you can’t beat what the FlexJet waterjet offers.

Auto Stand-Off – This is currently defined to be surface stand-off and not to be confused with vector stand-off in 5-axis mode. The current auto stand-off is based on a changing surface and will adjust vertically based on the angle of the “A” Axis, so there is five (5) axis taken into account during the calculations, but this is not the same as the tool vector stand-off. There is the ability to do the vector stand-off change while the machine is running manually with buttons on the screen.

Z-Reader Probe – The Z-Reader is a device for mapping the location of the surface. It can be controlled manually & programmatically. The option is NOT active while cutting & is retracted out of harm’s way. It can be triggered to verify the surface at every pierce before the cutting process starts, or it could be used to drive surface mapping of the whole part before cutting starts. It begins with initialization or zeroing of the device to the surface at the beginning of a program and then accumulates or tracks the difference from that zeroing effort.

Automatic Edge Finder – The edge finder is or can be utilized manually (Jogging Method & Screen Buttons), programmatically (M & G codes), or fully automatic routine (dedicated program). This option sets offsets & program rotation to match the orientation & location on the cutting table.

AC Unit Installed on Electrical Cabinet – The unit is mounted on the cabinet’s High Power (480v) side. It is close to the location where the drives are mounted. This option keeps the cabinet temperature stable and allows heat dissipation faster. The servo drives for all axes are the most significant contributors to heat inside the electrical cabinet.

5-Axis Renishaw CalibrationThe calibration unit is a Renishaw model APCA45 with a modified spherical stylus. The device has a retractable cover and air purge to clear debris & dust during the activation process. It mounts to a swing arm controlled by a pneumatic rotary, so it is out of the way during regular operation and swings into the calibration position for calibration only.
