Common Mistakes To Avoid When Using Waterjet Cutting Services

While waterjet cutting may be a highly efficient and versatile method for cutting various materials, there are still some common mistakes that users often make. These mistakes can lead to costly errors, delays in production, and even safety hazards. In order to ensure smooth operation and maintain the quality of your results, it is important to avoid these common mistakes.

Incorrect material selection

Not all materials are suitable for waterjet cutting. While it works well with metals, plastics, ceramics, and rubber, some materials, like tempered glass, may shatter under the pressure. Selecting the wrong material can cause damage, unnecessary waste, or even machine issues. Checking with the service provider about material compatibility before starting the project prevents such problems.

Using the wrong water pressure

Waterjet cutting operates at extremely high pressure, but different materials require different settings. Using too much pressure on soft materials can lead to unnecessary wear on the cutting head, while too little pressure on hard materials results in incomplete or uneven cuts. Knowing the correct pressure settings ensures clean cuts without causing material damage.

Neglecting the nozzle condition

The nozzle is a key component of a waterjet cutter. Over time, it can wear out, affecting precision and cutting speed. A worn-out nozzle may cause inaccurate cuts, rough edges, or inconsistencies in the design. Regular inspection and replacement of nozzles prevent errors and maintain cutting efficiency.

Ignoring proper fixturing

Securing the material properly is essential to avoid movement during cutting. Loose or unstable materials can shift, leading to inaccurate cuts and wasted materials. Ensuring proper fixturing and alignment before starting the process helps maintain precision and prevents costly mistakes.

Overlooking taper compensation

Taper occurs when the cut is wider at the top than at the bottom due to the nature of the waterjet stream. Not accounting for taper in the design may lead to parts that do not fit correctly. Some advanced waterjet systems have taper compensation features, but if not available, adjustments in the cutting parameters may be needed to minimise the issue.

Not considering cutting speed

The speed at which the waterjet moves affects the final result. Cutting too fast may result in rough edges and incomplete cuts, while cutting too slowly increases costs and production time. Finding the right balance between speed and accuracy ensures efficient cutting without compromising quality.
