Water Jet cutting services make use of a super high pressure stream of water that carries an abrasive grit. This abrasive mixes with the water through a venturi effect in what is commonly called the ?focusing tube? just prior to cutting. This mixture of water and abrasive grit exit the focusing tube at speeds of approximately mach 2.5. Cutting pressures range between 45,000 to 60,000 psi for standard cutting models. For brittle, fragile, or delicate materials, piercing pressures range between 15,000 to 20,000 psi, and resume the higher cutting pressures when the pierce has been completed. This low pressure pierce is not true of all machines, and cutting models.
Manufacturing companies are always looking for a cost effective edge. Wasted material, time spent in secondary operations, machine wear, and man hours relate to rising manufacturing costs. Water Jet cutting services offer a flexible and versatile alternative to other types of two dimensional cutting for most materials.
A water jet cutting service can be your defense in the cost battle. Metal cutting services help reduce material cost by reducing material waste. Parts are tightly nested using nesting software to maximize material usage. Machine wear, and no necessity for secondary processes, save you significant amounts of money per year. Custom blanks and prototypes are cut to customer specifications, using metals such as stainless steel, aluminum, brass, bronze or copper in a variety of shapes or dimensions.
