Abrasive compounds are included into grinding wheels to facilitate grinding and abrasive machining. Grinding machines also make use of such wheels.
Composite materials are often used for the wheels. It is made out of coarse-particle aggregate that has been crushed and bound together by a cementing matrix (known as the bond in grinding wheel jargon) to produce a solid, spherical shape. Depending on the use, wheels may have a wide variety of profiles and cross sections. A steel or aluminium disc with particles adhered to its surface might potentially be used to make them. Natural composite stones, such those used for millstones, were the first to be utilised as grinding wheels. Today, most grinding wheels are artificial composites constructed with artificial pebbles. Owing to the inherent safety dangers of a spinning disc and the composition and uniformity necessary to keep that disc from bursting due to the enormous pressures created on rotation, the production of these wheels is a precise and carefully regulated operation. Consumables, grinding wheels may last anywhere from a few hours to many years, depending on the use. Every so often, the wheel will let go a few abrasive grains. This happens because the grains eventually get dull and the increasing drag forces them out of the bond. This wear process exposes new grains, which initiates a new cycle. Good performance necessitates a certain amount of wear, and this wear rate is typically rather predictable for a specific application.
Types of Grinding Wheel
Grinders with Square Wheels
They are everywhere, so you can’t avoid seeing them. Simple grinding wheels may be found in garages and basements all around the globe. Chisels and lawnmower blades are only two examples of the kind of instruments that benefit most from their usage. Surely, you have one in your own house.
Grinder Wheels with a Huge Diameter
Large-diameter wheels are just like standard wheels in every way except for their size. These massive wheels have a broad grinding surface that is used to smooth the outside diameter of spherical items like carbide blanks. The Oil and Thermal Spray Industries are two other major users of OD grinders. Grinding wheels with a 36-inch diameter are a commercially available size.
The Cup-Wheel Grinder
Polishing stone and concrete is one of the most common uses for Grinding Cup Wheels. Cup wheels, however, may be adjusted to a fine enough grit to remove paint and glue without damaging the surface. When the abrasive size calls for it, cup wheels are utilised for resharpening and finishing.
Dish Grinder Wheel for Grinding
Dish grinding wheels are similar to cup wheels in appearance, but they are shallower and have a softer edge. Their slim profile makes them ideal for accessing confined spaces that would be inaccessible to a cup wheel. Besides those uses, they serve the same functions as a cup wheel.
Grinding Disc With Segments
You can get segmented wheels in a number of different designs, including 6A2, 1A1, and 2A2T. What sets this wheel apart is that rather of having a single, continuous abrasive rim, the abrasive pieces are put to the wheel in a more modular fashion. Among the many available forms, ASA also provides hexagons, pellets, and pie wedges. Get in touch with ASA for further discussion. These grinders are effective in removing substantial quantities of material quickly without harming the work surface when used in conjunction with cooling or lubricating fluids. To get the fluids where they’re required the most, each section forms a canal that relies on centrifugal force.
Cutter Disc Grinder
The material is ground away from an item using a wheel with a “cutting face.” The grinding edge is often rather thin and removes a great deal of material in one swift motion. Tile cutting and saw tooth shaping are only two of the many uses for precision tools. Abrasive materials like diamond and Cubic Boron Nitride (CBN) are used in grinding wheels to remove material off the surface of an item. The size of the abrasives is indicated by their grit size. Using a finer grit, you may polish or sand. Whether you’re grinding or stocking away, coarse abrasives are utilised to get the job done quickly and efficiently.
CHOOSING A GRINDING WHEEL
Welders and fabricators can rely on the performance of the abrasive grinding wheels available from Weiler Abrasives to get the job done quickly and accurately. You may choose from our grinding wheels that are either rapid cutting or long lasting, or both.
METAL GRINDING WHEEL TYPES
We have grinding wheels made for working on all metals in both our Type 27 and Type 28 designs. These wheel styles each have triple reinforcement for added stability in aggressive applications but differ in their profile to offer unique advantages:
- Type 27 grinding wheels: When mounted between 25 and 35 degrees, the flat shape and depressed centre of Type 27 wheels shine. In any case, operating angles of up to 45 degrees are possible when using these wheels to efficiently remove stock.
- Type 28 grinding wheels:The concave shape of Type 28 wheels makes them more manoeuvrable in confined situations and more aggressive at lower operating angles. Between 0 and 15 degrees is the sweet spot for their efficiency.
GRINDING WHEELS MADE FOR ALL METALS
In order to grind, a mixture of resin and abrasive grains is used in a wheel. When the wheel comes into contact with metal, the abrasive does the grinding, while the bond keeps the abrasives in place and keeps the wheel from warping. Abrasive materials range in hardness and abrasiveness. Consistent results and reliable productivity can be achieved by using a grinding wheel that is optimally composed for the given task and material. The grinder is also an important consideration when selecting a wheel for grinding. External wheel diameters are manufactured to suit a wide range of grinders. It’s also crucial to remember the inner diameter. Angle grinder wheels are mounted on a spindle, or arbour. Each grinding wheel has a unique recommended arbour size to ensure a snug fit. In addition to wheels that fit 7/8-inch arbors, we also stock wheels that fit 5/8-inch arbors, and wheels with 5/8-11 threaded arbour hubs for quick spin-on, spin-off mounting.
FINDING A GRINDING WHEEL THAT MATCHES YOUR NEEDS
Selecting a wheel with the appropriate abrasives can be more challenging than choosing a wheel of the appropriate size and type for the job. You should always start with the material in question when selecting a grinding wheel for a metalworking application.
CHOOSING A GRINDING WHEEL FOR ALUMINUM
Aluminum’s low weight and inherent resistance to rust and corrosion make it a go-to material for a wide variety of metal fabrication projects. Aluminum is about 30% as heavy as steel but may be just as robust and resilient with the right alloy. Due to its chemical makeup, aluminium production needs a grinding wheel designed for use with non-ferrous metals. It is for this reason that we produce aluminium grinding wheels:
- Tiger Aluminum: For use with aluminum-based alloys, nothing beats the Tiger Aluminum grinding wheel. With the addition of an aluminium oxide mix, this silicon carbide grinding wheel maintains a high cut rate for its entire service life. By preventing the wheel from gumming up, a non-loading compound boosts productivity without sacrificing longevity. The metal you polish with will not rust again thanks to the purity of our Tiger grinding wheel.
CHOOSING A GRINDING WHEEL FOR STAINLESS STEEL
In order to get the best results when grinding stainless steel, which is more expensive than carbon steel but more resistant to the elements, it is essential to use the proper abrasives. Using INOX wheels or wheels certified as contaminant-free is paramount when grinding stainless steel. The wheels meet this standard if they have an additive content of less than 0.1% iron, sulfur, and chlorine during production. With our grinding wheels, we are able to overcome this difficulty, and we even have a choice between two solutions:
- Tiger Ceramic: We offer a Max Performance option with our Tiger Ceramic wheels.
