Not All Abrasive Is the Same

There are many different kinds of abrasives including garnet, staurolite, olivine, crushed glass and copper slag. There are also different brands, grades and sizes of abrasives. Garnet is the most popular abrasive for abrasive waterjet applications because it balances cutting speed, cost, low silica content and mixing tube wear.

A Primer on Waterjet Mixing Tubes

The terms nozzle and mixing tube are often interchanged when people are talking casually about waterjets. A nozzle is the whole assembly where the water is focused through an orifice, abrasive is added to the jet stream in a mixing chamber, and the combined mixture is focused and extruded from the machine. The mixing tube is the last part of the nozzle that concentrates and directs the water/...

Waterjet Collision Prevention

When collisions happen, they usually come about because of one or two reasons:

A slug freed from the material has been pushed up from below, creating an obstacle on the cutting surface The material is not perfectly level

Fortunately, there are a few simple tricks to help prevent collisions and unnecessary downtime.

Slugs that create problems are small enough to be light...

The Importance of Slats

Slats are the stainless steel plates that support the material being machined in an OMAX abrasive waterjet. They are the best, most universal solution for supporting material. The standard slats that come with your OMAX waterjet can easily handle everything from metal plate and glass to stone and plastic, as well as nearly any other material.

Using Sacrificial Material

If you are accustomed to cutting aluminum or steel of 1/4 inch (or thicker) flat stock, you probably haven’t needed to use a sacrificial material. However, when cutting thin, brittle or tubular material, a sacrificial piece may make all the difference in quality waterjet machining.

Why should you cut on sacrificial material?

The three main reasons to use backing sacrificial...

Tips for Cutting Stone and Ceramic on Your Waterjet

Pierce stone countertops without chipping. Work ceramic with minimum dust. From granite to Dekton, OMAX abrasive waterjets allow for quick, accurate, and safe machining. Fabricating with water and abrasives instead of wasting money on costly specialty saw blades ensures a cutting medium that is never dull and a fully secure process – especially with our tips for cutting stone and ceramic...

Why Waterjet Is The Best Method For Cutting Stainless Steel

Almost every machine tool claims they are the best at machining stainless steel. For some applications, the tolerances achieved by most machine tools (and subsequent effects imparted by the machining) is fine. However, when a fabricator or prototype creator is looking to produce a high precision part, have it weld ready, or get it done now, there is really only one method – abrasive waterjets...
