Abrasive Waterjet Advantages & Disadvantages. Industry Trend No. For cutting hard materials, abrasive particles are used in the water jet.These abrasive particles erode metal from the contact surface. If there is no high demand for tolerances the material plate can just be put on the cutting table with a weight on top. The adaptive cutting process gives unique possibilities to cut combined materials. The slurry is pressurized and delivered through a nozzle to the machined surface. Rama Sreekanth, in Reference Module in Materials Science and Materials Engineering, 2016. Recycled garnet can be more effective in cutting compared to alluvial garnet as the edges are sharper. But does waterjet cutting make sense for 2-axis cutoff of small metal parts? For intricate geometries, sharp corners, unparalleled wear resistance, excellent cutting speeds and machinability, copper tungsten is the material of choice. The hydraulic, mixing, and abrasive parameters are associated with the hardware, whereas the cutting parameters are associated with the use of AWJ in a specific operation. On a micro scale the erosion mechanisms momentarily create local heat upon contact but the continuous cooling by water will remove the heat and temperatures will cause no thermal effects on the cut surface. Benefits of the cycle incorporate the accompanying negligible residue exceptionally when cutting of asbestos, less warm or deformity stresses, for example, the workpiece is cold cut, diminished force utilization, striation is decreased, high exactness because of little workpiece miss happening, no fire perils since water is inflammable, the capacity to cut practically any material, profound kerfing ability, high edge surface quality, and no hefty cinching of a workpiece is required (Memarianpour et al., 2021; Mensah et al., 2021).
When a fine stream of energized particles strikes the work surface, a range of erosion mechanisms are activated and cause material removal. The application of water-jet cutting in industry dates back to the 1930s. Eddy current testing is an important method of nondestructive testing that is often used to inspect for flaws in the surface or sub-surface of metal materials. The main element of an abrasive-waterjet setup is the reciprocating pump which is used to pump pure water at extremely high pressure of 40006000 bar. Tungsten & Molybdenum Techniques such as EDM and ultrasonic machining offer the ability to machine intricate profiles using a shaped tool but with a relatively low material removal rate.

Learn why the characteristics of titanium tube make it a good choice for medical devices and other applications that require strength, light weight, and corrosion resistance. By adjusting the size of the nozzles in the cutting head, the process is capable of cutting thick materials like 300 mm steel or titanium. Some of these advantages include no thermal effect, high machining versatility, high flexibility, small cutting force and high productivity. Cold sawing can do high-speed, burr-free cutoff of rods, tubes, and extrusions, but it is not ideal for very short lengths, smalls ODs/IDs, or hard metals. 2.16 shows a sketch of a setup for AWJM [23]. Learn some common myths about plastic and reasons why it may not be a better choice than metal tubing for medical device applications. Find out if metal passivation is the right finishing option for your precision small metal parts or other application.
The absence of adverse effects on material properties, offered by cold cutting, also has the important advantage that finishing work can often be avoided. Fig. Important quality parameters in AWJM are material removal rate (MMR), surface roughness, kerf width and tapering of the kerf. Consider the methods used for heat treating metals, as well as the effects, when specifying your requirements for the cut-off of small metal parts. Fig. The ability to cut various materials with the same tool setup as described above has the great advantage of user friendliness in the process. Another advantage of water-jet machining is that the workpiece can be cut without interfering with its inherent structure, as there is no obvious temperature rise during the machining process. Learn the vital components of an effective quality control program and its role in ensuring metal parts meet their requirements for design and function. Consequently, thin structures can also be cut without being affected by the jet forces. Kowsari et al. To ensure optimal cutting with waterjet cutting, the right standoff height the distance between the waterjet nozzle exit and the workpiece is 1 mm (0.0394) to 1.5 mm (0.0591). In circular runout vs. total runout, the first controls variation in circular features of a part while the other controls variation in the entire part surface. The key to calibration tolerance is understanding both what a device is capable of doing and the tolerance to which the device has been calibrated. Learn how precision cut off and stamping compare in achieving distortion-free flatness, a sharp edge, and the precise exterior diameter needed for a spacing ring. However, where parts need to have a close tolerance and smoother edge finish, a slower cutting speed is required. Other than drilling studies, milling and abrasive water jet machining (AWJM) behaviors of the biocomposites were also reported. Learn the key parameters for choosing a method of 2-axis precision cut off of metal parts based on part type, material type, and part dimensions. As process parameters considerably affect machining quality, proper setting of the parameters is of extreme importance to realize products with desired quality. Table10 summarizes the various investigations rallied with the machining of biocomposites. Similar to any AWJ technique, the surface roughness is associated with the abrasive diameter and particle mass flow rate. The process is suitable for cutting complex contours on wide range of materials. Double disk grinding provides dimensional accuracy for metal part applications that require tight tolerances, parallelism, flatness, and thickness control. With the Finecut waterjet machines you can produce your own fixtures for cutting. 2: Manufacturing globalization and regionalization provide opportunities for partnership, innovation, competitive advantage, and growth. In addition, when cutting fibrous material, some of the waterjet stream slides around around the material to be cut instead of going through it and making a clean cut. Learn the difference and how to measure them here. The stagnation zone is the area of significant deceleration of abrasive particles when approaching the surface. Abrasive waterjet cutting does not generate heat. Knowledge Center Abrasive waterjet (AWJ) machining is a technique in which high-speed waterjet nozzles eject abrasive particles to erode work piece material after impact (Fig. The process of creating a vacuum atmosphere, either repeatedly or in one-time production, is an important part of electronic component manufacturing.
