ABSTRACT: The introduction of abrasive material into water jet technology in the 80s extended the range of materials, which could be cut to practically all technical materials, which has been one of the largest step of development in this technological branch. Since then two different types of abrasive water jets developed. Due to their different jet generation these differ in their properties, which define their application fields. Whereas abrasive water injection jets are mainly applied for industrial machining, the core application fields of abrasive water suspension jets are in the decommissioning and dismantling of offshore structures and nuclear power plants as well as in demilitarisation. In this paper the generation mechanisms of abrasive suspension jets are explained and the influence of the main parameters on the cutting efficiency presented. The properties of this type of jet are marked of those of abrasive water injection jets leading to their specific application fields.

Centerless grinding. Creep-feed grinding. Cylindrical grinding. Gear grinding. Tool grinding. They all demand precision. And to achieve the highest precision, you need the best abrasives.
Plus, we have the foremost technical and sales expertise to develop custom solutions just for you. We have solutions to boost the efficiency and precision of your grinding operations, from creep-feed to gear grinding and everything in-between.
Whether you manufacture cutting tools, turbines, gears or bearings, 3M grinding wheels help you turn out higher-quality parts — faster. To get perfectly round parts from the centerless grinding process, you need the right machine and the right abrasives. Surface and creep-feed grinding are frequently used in the bearing industry, and turbine manufacturing for power generation.
The process is divided into several steps, and consistent material removal is essential. For removing oxide scale and defects on casted steel before further processing, Hot Pressed Wheels are used.
Main applications are slab and billet grinding on all existing steel grades — making 3M abrasives the ideal solution. Inside diameter ID and outside diameter OD cylindrical grinding are commonly used grinding techniques. Our grinding wheels cut cool and perform well with low contact pressure — making them an ideal choice for manufacturers across multiple markets. Roll Grinding Wheels are used for reshaping of casted or forged rolls.
These Rolls are used in Rolling Mills for forming process of casted metals. Thankfully 3M offers an expansive abrasives portfolio that covers bevel gear grinding, threaded gear grinding and single rib gear grinding. The micron-graded mineral produces a consistent, repeatable finish, and 3M innovation continues to drive the technology forward. Modern cutting tool manufacturing means complicated geometries, very high tolerances and demanding surface finish requirements.
With these requirements in mind, 3M designs and manufactures high-performance grinding wheels that are up to the challenge. Cut-off wheels are used in the steel production and steel processing industries to cut metal bars, billets or tubes of any dimension and any grade.
Cutting differs according to the application: Chop stroke for single bar and narrow layers, travel cut for wide layers, and rotary cut for tubes. Excellent performance, efficiency, and a clean, straight cutting surface are essential, making 3M cutting wheels the ideal solution.
As an integral part of modern precision grinding technology, conditioning of grinding wheels — consisting of dressing and cleaning — is one of most important grinding parameters to determine the material removal rate, the grinding forces, the surface quality and reproducibility of grinding quality.
Our abrasive experts can get you what you need, whether you want to learn more about a specific grinding application or just need help finding the right product to get the job done. Give us a call at Cuts faster. Runs cooler. These clean, sharp points mean an abrasive that cuts faster, runs cooler and lasts much longer than conventional abrasives.
Where conventional abrasives generate excessive heat buildup, the heat generated from our Precision-Shaped Grain is directly dissipated from the workpiece into the chip. Save time. Save money. Pair this broad 3M product selection with our world-renowned industry expertise, service and support, and the result is a winning partnership.
Looking for something else? We also offer a full line of alternative abrasives to suit your specific needs. We offer a full selection of superabrasive wheels that make easy work of carbides, hardened steels and more. View the videos below to see the 3M difference for yourself. For the first time, Precision-Shaped Grain technology has been incorporated into a threaded grinding wheel.

Sanding wood is a process that, if done correctly, makes the wood surface very smooth by "machining" the surface of the wood with a multitude of very small sharp edges; in other words, sanding is the process of removing surface imperfections, including scratches, from a surface and thereby making the surface smooth. The machining of wood, when sanding, is done by small pieces of abrasive with sharp edges. These sharp edges are fastened to a sheet of material called sandpaper. The degree of success when sanding wood depends to a large extent on the sandpaper used and to a lesser extent on the person or machine being used to do the sanding. Often smaller and smaller grits or particles are used in successive sanding operations to achieve an acceptably smooth surface.

Material removal applications vary significantly, and so do their automated solutions. Knowing the terms can help guide potential customers to the best sources for information, technology, and service. Removing large burrs is often a two-step process. For some deburring applications, Barnett suggests a chamfer, or angled cut can be used. For deburring or deflashing applications where material stresses should be avoided, Barnett recommends a radius, where the force and position of the rotating surface of a compliant abrasive are actively controlled through electrical or pneumatic means. Deflashing is used to remove material from parts made by additive processes, such as injection molding of plastic. Depending on the material, size, and other application requirements, flash material can be removed by any number of rotational media, from orbital sanders to grinders and other hard tools. Sanding is a well-known surface finishing technique used in a multitude of ways, such as refining the finish of manufactured stone for sinks and tubs.

Manufactured using unique abrasive grains coated to paper, cloth, film, vulcanised fibre or synthetic backing, converted into different shapes such as belts, rolls, discs, sheets. For applications including heavy-to-medium material removal, fine finishing, and light blending and polishing. Abrasive grains joined with an organic or vitrified bond molded into various shapes including grinding and cut-off wheels with or without reinforcements, segments, mounted points, dressing sticks and sharpening stones.
An abrasive is a material, often a mineral , that is used to shape or finish a workpiece through rubbing  which leads to part of the workpiece being worn away by friction. While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes. In short, the ceramics which are used to cut, grind and polish other softer materials are known as abrasives. Abrasives are extremely commonplace and are used very extensively in a wide variety of industrial, domestic, and technological applications. This gives rise to a large variation in the physical and chemical composition of abrasives as well as the shape of the abrasive. Some common uses for abrasives include grinding , polishing, buffing , honing , cutting , drilling , sharpening , lapping , and sanding see abrasive machining. For simplicity, "mineral" in this article will be used loosely to refer to both minerals and mineral-like substances whether man-made or not. Files are not abrasives; they remove material not by scratching or rubbing, but by the cutting action of sharp teeth which have been cut into the surface of the file, very much like those of a saw. However, diamond files are a form of coated abrasive as they are metal rods coated with diamond powder. Abrasives generally rely upon a difference in hardness between the abrasive and the material being worked upon, the abrasive being the harder of the two substances. However, is not necessary as any two solid materials that repeatedly rub against each other will tend to wear each other away; examples include, softer shoe soles wearing away wooden or stone steps over decades or centuries or glaciers abrading stone valleys.
