What Makes OMAX Unique?

What Makes OMAX Unique? A waterjet is made up of several critical key components, such as the high-pressure pump, the nozzle, and control software. OMAX designs manufacture and supports their waterjet systems all from their production facilities in Kent, Washington, USA. Valuable Features at No Additional Cost OMAX is the only manufacturer to guarantee free OMAX operating software upgrades for life to owners of our premium OMAX line of waterjets. This guarantee saves owners thousands of dollars over the life of their investment but more importantly ensures that they will receive all benefits derived from software enhancements. Upgrades are implemented to improve accuracy, provide faster cutting speeds, enhance system monitoring, and provide additional waterjet cutting capabilities. Service & Support Commitment OMAX is dedicated to being knowledgeable about your applications, expectations, and concerns. They pay attention to the smallest detail to ensure your satisfaction. The OMAX Interactive Reference Guide ( OIR ) comprised of over 3000 pages, covers every aspect of operating and maintaining your investment. It is unequalled for providing application solutions. The OIR is available to you 24 hours a day, seven days a week, including holidays, and is instantaneous to answer your questions. Materials Waterjets can cut almost any material. Pure waterjets can quickly and accurately cut soft materials such as rubber, foam and other gasket material. Abrasive waterjets can cut almost any other material over a very wide range of thicknesses: Virtually all metals, including hardened tool steel, stainless steel, aluminium, copper and titanium Non-tempered glass, including multi-layer laminated safety glass Composites Laminates Stone Most ceramics Get your FREE test cut and see the OMAX difference Run Sizes Set-up time for a waterjet with an advanced control system is minimal. Advanced control software (such as the OMAX Intelli-MAX Software Suite) can automatically program the cutting path of the desired part directly from a CAD drawing. Just lightly secure the material stock to the cutting table and enter the material type and thickness into the control computer. The control system does the rest and an accurate part is produced on the first run. Table Sizes Waterjet cutting table are now available in a wide range of standard sizes, ranging from small 2′ 5″ x 2′ 2″ (737mm x 660mm) tables to very large 26′ 8″ – 46′ 8″ x 13′ 4″ (8.1m – 14.2m x 4m) tables. The two considerations in selecting a table size are the size of part to be made and the size of stock material to be used. It is generally easiest and most economical to err on the side of a larger table that will handle all intended material stock sizes and future larger parts. Special Features Water cutting has some special characteristics that make it particularly attractive for some applications: Waterjets cut without heat. This means that there is no thermal distortion to complex and intricate parts and no heat affected zone that might change material properties. It also means that secondary machining processes, such as thread-tapping, are easily carried out on a waterjet-cut blank. Waterjets make a very narrow cut and have very low cutting forces. This frees part designers to create intricate parts that would be virtually impossible to make with conventional manufacturing processes. Very complex shapes and contours are easily possible with waterjet cutting. An additional benefit when the expensive material is being machined is low waste costs. Advanced motion control permits production of precise parts. Traditional waterjets cut parts to a precision in the range of ±0.010″ (0.25mm). However, by using mathematical models to account for and correct the natural error-creating curvature of a moving waterjet, modern high-precision waterjets with advanced control systems such as the OMAX Intelli-MAX Software Suite can make parts to a general tolerance of ±0.005″ (±125μ). The most advanced systems have computer-controlled taper-compensation cutting heads and can control key part dimensions to an accuracy of ±0.001″ (±25μ). Environmental Considerations Early waterjets had a well-earned reputation for being noisy and dirty. An exposed water jet is noisy and an exposed abrasive waterjet can throw a lot of abrasive dust into the air. However, these factors are eliminated in modern systems by simply cutting under a thin layer of water. The water layer reduces the noise level to below that of most machine tools and eliminates the dust by keeping the particulates in the water. An abrasive waterjet machine cutting underwater can be placed anywhere that you might place a conventional machine tool. No noxious fumes or smoke is generated, and the part does not become contaminated with cutting oils. A waterjet machine generates two waste streams: Excess water containing very small amounts of solid fines, which can be filtered if required by local regulation and then sent directly to a wastewater drain. Kerf material and garnet waste can be sent to a landfill. If the material being cut is poisonous—lead or beryllium, for example—both waste streams must be cleaned to meet environmental regulations and the water may be recycled. Operating & Maintenance Costs An abrasive waterjet machine costs between $25 – $30 per hour to operate for consumables and maintenance parts. At operating pressures above 60,000 PSI (4,137 bar) more maintenance is required and unplanned downtime can increase dramatically. Ultra high pressures result in higher operating costs due to accelerated metal fatigue in high-pressure components used in pumps and plumbing. For this reason, waterjet cutting machines usually operate most economically and reliably in the range of 60,000 PSI (4,137 bar) or less. Maintenance items include all parts wetted by the high-pressure water and all parts through which abrasive flows. Nozzle parts are replaced at 50 to 100-hour intervals, and pump seals have replaced near 1,000-hour intervals.
