Overcoming the Challenges of Stone Cutting with Waterjet Technology

In a recent survey on home buying preferences, one out of every four respondents said they preferred a custom-built home rather than a new home already built or an existing home.[1]  There are many advantages to having a custom built home: unique finishes, custom floor plan, superior quality, and getting exactly what you want.

The Importance of Standoff Height, Especially with Bevel Cutting

Standoff height, the distance between the tip of the mixing tube and the material you are cutting, is important when cutting parts on a waterjet. In a previous blog I provided recommendations for proper standoff height. In general, stand off height should be about 0.100” (2.5 mm), or as thick as a dime. When your jet is perpendicular to your part, straight up and down, then raising the standoff will increase noise, mess and round the top edge of the part. You will lose a little cut power as well.

It’s important to maintain stand off under conventional waterjet cutting.

Tough Applications Where Waterjet Shines

It is true that waterjets are used for common materials such as steel, aluminum, gasket, and foam. But many people feel the tougher applications are where waterjet really shines. In this post I’ll highlight some that I believe best illustrate waterjet and abrasive waterjet capability.

  1. Stone
  2. Composites
  3. Exotic metal: Titanium and Inconel
  4. Thick insulation
  5. Cement board

The first three are abrasive waterjet related, and the last two use pure waterjet.

Guest Post: 5 Key Waterjet Terms We Should All Understand

I’m pleased to say that we have a guest blogger today.  Colleen Carnagey is a major part of Flow’s marketing group and she would like to introduce to you a new feature on our website that might be of real value to you as you become more educated on waterjet capabilities.

Over the years waterjet has created its own vocabulary. I’m fairly new to Flow (in Flow terms–4 years isn’t much on 20), and one thing I realized almost immediately is to feel confident in your understanding of waterjet technology as a whole, you must feel confident in your understanding of the terms used to explain it.

The Vital Role of Manufacturing to GDP

When the governments of the world undervalue manufacturing’s impact on Gross Domestic Product (GDP), the result can be detrimental to the economy. The results can include taxes and laws being put in place by governments without understanding the true impact on manufacturing. A recent study by Manufacturing Alliance for Productivity and Innovation (MAPI) suggests the US has been significantly undervaluing manufacturing’s contribution to GDP. If you are reading this post outside the US then I hope the topic at least has some relevance to you in your own country.

Geologic versus Supersonic Erosion

The Colorado River versus Waterjet

Waterjet gives the best edge. The surface is unaltered, exhibiting no heat or stress damage.  This outstanding edge quality it is created by supersonic erosion.

Erosion is an extremely gentle form of material removal, however it achieves amazing results.

For example: the Colorado river can erode the one mile deep Grand Canyon in 35 million years, and the abrasive waterjet can erode over one foot thick of granite at 0.2 inch per minute (5mm/min).
