Waterjet cutting is widely used by leading aviation manufacturers. • Abrasive Water Jet Machining (AWJM) is non- traditional or non-conventional machining process. When an abrasive material … Here are some of the sectors that use waterjet cutting for their profiling needs. In this blog, we outline some of the most commonly found ones, split by industry sector. As a means of replacing the processes of drilling, sawing, broaching, gear cutting, profile milling, plmching, slitting, spline cutting and hlanking, abrasive jets are used to machine materials with remarkable accuracy and quality of finish; abrasive jets are typically advertised to beaccurate within +/- … Water Jet cutting uses an ultra-high pressure stream of water to carry an abrasive grit. • In these processes, the mechanical energy of water and abrasive phases are used to achieve material removal or machining. In bonded abrasive processes, the particles are held together within a matrix, and their combined shape determines the geometry of the finished workpiece. Finally, another practical application of water jet cutting is preparing for welding. When high-pressure water jet emerges from a nozzle, it attains a large kinetic energy. The water pressure is usually set up to 400 MPa and is generated with a hydraulic intensifiers specially designed for this technology. Contact. The abrasive does the cutting through a mechanical sawing action, leaving a smooth, precision cut surface. The most commonly cut parts on a waterjet include: Waterjet cutting’s ability to deliver precision machining of small parts in difficult materials, makes the technique ideal for the medical/surgical sector. The concept of material cutting using ‘abrasive waterjets’ in industry was started in the late 1980's. About Us
Making a chamfer with a water jet machine offers precision and an ideal angle for welding, and allows for deep penetration of the weld bead into the material in order not to carry out a "central" weld, not a "peripheral" weld. This site uses Akismet to reduce spam. In order to cut harder materials like metals or granite, an abrasive material is mixed in the water. Water-jet cutting is a material-removing cutting process that cuts different materials without thermal stress. Schematic illustration of water jet machining. Tag Index

For machining hard materials like carbide, ceramic, etc. In this machining process a high speed steam of water jet impinge on the work piece which removes metal from contact surface by erosion. As an industry with no margin for error, the aerospace department emplo… Abrasive-waterjet machining (AWJM) is widely used in the cutting of hard and low machinability materials like titanium alloys, ceramics, metal–matrix composites, concrete, rocks, etc. The nozzle is made of sintered diamond and exit nozzle is about 0.05 to 0.35 mm in diameter. Abrasive water jet machining makes use of the principles of both abrasive jet machining and water jet machining. In pure WJM, commercially pure water (tap water) is used for machining purpose. As part of this process, the jet of water might be used for cutting, slicing, making flooring inlays, carving and other such processes. But there are other factors to consider. In AWJM abrasives below 0.45-micron size is mixed with water and compressed to 420 MPa with this machine a 25 mm thick Aluminium has been cut for 100 mm/min. It is the preferred method when the materials being cut are sensitive to the high temperatures generated by other methods. On zinc-nickel steel of 25 mm thick the rate of cutting is 35.5 mm/min, but on the same work, Electric Discharge Machining (EDM) can cut 2.5 mm/min. The process is convenient for cutting soft and rubber-like materials because teeth will get clogged in conventional methods. If you’re unsure whether waterjet cutting is the right method for you or simply want to find out more, download our free and comprehensive eBook ‘An engineer’s guide to waterjet cutting’. Cutting of hard materials have been overcome by introducing abrasives in water in WJM also called Abrasive Water Jet Machining (AWJM). • Abrasive water jet machining – Developed in 1974 to clean metal prior to surface treatment of the metal. Water Jet Machining (WJM) is a mechanical energy based non-traditional machining process used to cut and machine soft and non-metallic materials. Environment friendly : The Water Jet Machine uses water and garnet to cut. However as the high velocity water jet is discharged from the orifice, the jet tends to entrain atmospheric air and flares out decreasing its cutting ability. Initial setup cost for WJM process is very high and hard materials cannot be cut. In Water Jet Machining (WJM) process, water jets alone (without abrasives) can be used for cutting.
