If you are in the part manufacturing business, you understand the importance of precision. After all, a burr on the edge of metal or a measurement difference of a fraction of an inch could make the difference between a part that fits and one that does not. Waterjet cutting machines are a great investment for manufacturers because the machines provide precision cutting and automated processing for every single part. Before you buy that first waterjet, though, here are a few things that you should understand.
What Is Stream Velocity?
Stream velocity is an important consideration when you're shopping for a waterjet. This type of cutting is a process of supersonic erosion. Increasing the velocity of the water stream increases the speed and efficiency of the cutting process itself, so the higher the velocity, the more efficient the machine is likely to be. When you're using an abrasive as part of your cutting process, you can actually minimize the amount of abrasive used when you have a higher velocity stream. The faster that abrasive moves, the faster it cuts and the smaller the stream diameter. This translates to less required abrasive to get the job done.
What Kind Of Pressure Do You Need?
When you're looking at waterjet cutters, the water pressure directly affects the cutting ability of the stream. There are multiple different pressure levels available. Ultrahigh-pressure ratings are often the standard choice for most systems because it can easily deliver enough water to maintain the velocity necessary for cutting.
Hyperpressure is another option if you need something more advanced than the traditional machine. This is sometimes the case if you are working with hardened steel or other, more challenging, materials. When you understand the pressure options, and how that pressure directly affects the stream and the velocity, you'll be in a better position to choose the right one.
What Is The Linear Intensifier Pump?
The linear intensifier pump is another key component of your waterjet machine. These pumps rely on an intensification ratio to increase the pressure in the water. The hydraulic oil in the pump is pressurized, and that pressure pushes against a plunger, transferring the pressure to the water on the other side of the plunger. The intensifier pump is a key component of your cutting machine because it allows for long-term or nearly consistent production.
If you work in a busy or highly demanding production atmosphere, you'll want a machine with a linear intensifier pump to ensure reliability. For more information, check with companies like Cincinnati Ventilating Company Inc.
