Submerged Cutting

Cut Quiet. Cut Clean. Cut Under Water.

There's a common misconception that waterjets are noisy and dirty machines. While it's true that cutting above water can be noisy and throw a lot of abrasive dust into the air, modern abrasive waterjets let you cut under a thin layer of water, reducing the noise level to below that of most machine tools and keeping the abrasive particles in the water, not in the air. A waterjet cutting...

Used Abrasive

What Can You Do With Used Abrasive

With subtractive machining processes, the discussion eventually turns towards what to do with the collected leftover bits. While CNC mills have to worry about material chips and oils, abrasive waterjet users have to deal with spent abrasive. With abrasive feed rates capable of exceeding 2lbs a minute, that spent abrasive can accumulate at a very rapid rate. What to do with that used abrasive...

Top 10 Reasons to Attend A Tradeshow

Top Ten Reasons to Attend a Trade Show

There are many reasons to attend an industry trade show. While there are usually some costs involved for travel and registration (although you can often get a complimentary show pass), the value of what you gain in knowledge, exposure to new products, business contacts, and ideas to enhance your own business typically far outweighs the costs.

Comparing Motion Control Systems in Abrasive Waterjets

 

Positioning accuracy is a critical aspect of producing tight tolerance parts when cutting with an abrasive waterjet. The more precisely you can position the jet, the more precisely you can machine the part. A motion control system positions the cutting nozzle along the X- and Y-axes of a waterjet. This system is comprised of motor and drive components, a controller and...

Types of Taper Inherent to Waterjet Machining

In waterjet machining, taper refers to a difference in the kerf width at the top of a cut and the kerf width at the bottom of a cut. A typical waterjet cut has a slight taper, the most common type being V-shaped taper.  This type of taper is generated because the jet stream loses some of its cutting energy as it cuts deeper into the material...

Piercing Method

4 Piercing Methods In Abrasive Waterjet Machining

Abrasive waterjets make it easy to quickly cut precise parts from almost any material. How the machine pierces the material affects the overall production time and resource usage. Several piercing methods have been developed to deliver optimized cutting for various material types, thicknesses and part geometries.

#1 Stationary Piercing

This is the simplest and earliest piercing method...

Water Savings

EnduroMAX Pump Saves You Money

The OMAX EnduroMAX pump is more efficient than older intensifier-type pumps, but what does that really mean in day-to-day operations? At the core, it means that the EnduroMAX pump delivers more nozzle horsepower, or JetPower, versus intensifier designs. At the same time, the higher water requirements of the intensifier design means that you will need more input water to deliver less horsepower...

Direct Drive Efficiency: Doing More with Less

The muscle behind waterjet technology is a high-pressure pump that converts electric motor horsepower to nozzle hydraulic horsepower. The more nozzle horsepower, the faster you'll cut. However, with two different pump types used in waterjet cutting systems - hydraulic intensifier pumps and crankshaft-driven direct drive pumps - how do you know which type is actually more effective? Here...

The Whole is Greater than the Sum of the Parts

When someone looks at adding an abrasive waterjet to their shop, there are many points to consider, such as the size of the machine and the operating requirements. Ultimately, though, it comes down to one thing: money. Whether saving it or making it or a combination of both, money is the dominant concern. With so many variables surrounding abrasive waterjet systems, it is easier for...

The Rest of the Story: Software's Effect on Cutting Speed

When it comes to evaluating abrasive waterjet performance, cutting speed is typically one of the most important attributes. There's been a lot of discussion in the industry around cutting speed and pump power. But that's not the whole story if you're cutting anything other than a straight line. If you're cutting parts with any kind of complexity, like corners, curves and...
