Precision Practices: Homing

Homing an abrasive waterjet is the process of establishing a location on the machine’s cutting table where the nozzle can be moved in a repeatable way. An absolute home is usually established at the bottom left corner of the machine. This is a fixed point that determines all other points on your cutting table. Read

Preparing for Your Waterjet

If you are waiting for your newly purchased OMAX abrasive waterjet to arrive, or you’re just thinking of adding an OMAX to your shop, you’ll want to make sure your facility is prepared to use your new machine. Below is an overview of general requirements you’ll need to consider before the OMAX installation technician arrives at your location. Read

Precision Practices: Kerf and Tool Offset Adjustment

The mixing tube on your OMAX abrasive waterjet is made from ROCTEC composite carbide; however, it will wear with 60,000 psi of abrasive running through it. Below is the image of a mixing tube cross section. This mixing tube had been used for 152 hours. You can see the changing width due to the abrasive wear producing distortion throughout the tube. Read

Precision Practices: Tool Offset

The material and thickness will be determined by what you are cutting. Tool offset is the distance that the tool has shifted away from the cut path to compensate for the diameter of the jetstream (kerf). Note that the offset itself is usually half the width of the kerf. Read

Creating a Technical Support Report

Often when you experience an issue that may need customer support, support may ask you to run and submit an OMAX Technical Support Report. This report includes most of the information the technical support staff will require to understand your problem. In addition, the Technical Support Report allows OMAX to reproduce your problem at OMAX (the report includes your settings files, which can be loaded into MAKE to exactly reproduce your settings). In other words, you will get a faster and accurate answer if you e-mail the Technical Support Report. Read

Precision Practices: Lead-ins and Lead-outs

With lead-ins, the mixture of water and abrasive starts off cutting into the material at an optimal distance and angle away from the desired cut path. Cutting with a lead-in will let the waterjet stream pierce completely through the material prior to actually cutting the desired part path. A lead-in has three purposes: Read

What Is A Cutting Model?

The abrasive waterjet cutting model is, perhaps, the most significant factor in propelling abrasive waterjets into mainstream manufacturing. Advancements in the OMAX cutting model have decreased part production times, increased cutting precision, and made OMAX abrasive waterjets very easy to program. Yet, there’s not much discussion about what a cutting model is, or what it does. Read

Learn different types of nesting and see how to use it boost productivity and reduces waste in your waterjet cutting work. Read

OMAX 25th Year Anniversary

25 years ago, the founders of OMAX believed that a company could thrive in manufacturing with a focus on abrasive waterjets. Their mission, to provide precise, easy-to-use, cost effective, standardized, reliable, high quality abrasive waterjets with superior after-sales service, has endured to mold OMAX as the leading company in the waterjet industry. We celebrate our milestone, not by listing our accomplishments but, by celebrating our customers and the employees that made it possible. Read

Taper Compensation

Depending on the cutting conditions, geometry of the cut, the material and other parameters, the cutting edge can take on different shapes that are commonly referred to as taper. A V-shaped cutting kerf will produce a part with a top width smaller than the bottom width. The reverse can also be true, where the bottom width is smaller than the top width. Read
