How many types of grinding wheels

Wire wheels consist of a set of wires attached to a circle shaped base. Similar to other angle grinder discs, wire wheels are produced in different shapes and sizes because they are used for different purposes.

If a wire wheel has thick, twisted bristles, it is considered more abrasive and is able to get the job done faster and easier. On the other hand, thinner and more straight bristles are considered less aggressive and are used for finer jobs.

If you want to remove rust from a workpiece, one of the fastest and easiest ways to achieve a clean surface is by using a wire wheel. These angle grinder attachments are also used to get the paint off of a surface. Diamond cutting discs are undoubtedly the sharpest among angle grinder discs. These wheels have diamonds fixed on the surface of their edges. They normally have a cutting rim that the cutting process is done with them. The higher the cutting rim, the more durable they are and the longer you can use them.

Ronix produces diamond cutting discs with a 10mm cutting rim which are efficient and extremely resistant. Because of their diamond edges, the diamond cutting discs are suitable for cutting resistant and hard-to-penetrate materials like all types of granite. They are also used for both dry and wet cutting operations.

If you want a finished and shiny surface, then attaching polishing pads to your angle grinder can get you what you want. The name itself is self-explanatory; with a polishing pad, you can gently polish your desired surface. Just like any other attachment for angle grinders, polishing pads are produced in a wide range of shapes and materials that each, can create a unique finished look.

Be sure to use polishing pads on an angle grinder that has a speed control switch. Because polishing requires a specific speed, not all angle grinders are suitable for polishing tasks. For making the surface of a metal workpieces shiny, polishing pads are the right accessory for you!

This is why polishing pads are widely used in auto body shops. Thanks for your attention. Your email address will not be published.

It is a must to have a clear understanding of the safety related to the wheel grinder. It is also equally important to get the right wheel, and hence to know the different types. A grinding wheel is an expendable wheel that carries an abrasive compound on its periphery.

These wheels are used in grinding machines. Cup wheel: A cup wheel is used in Tool and Cutter grinders. It is used and dressed on the side face and has the advantage of producing a truly flat surface on the side of lathe tools. Straight wheel: A straight wheel is among the most common style of wheel and is found on bench or pedestal grinder, and is much preferred over chisels for their advantage over the latter.

Cylinder wheel: A cylinder wheel has a long, wide surface with no centre mounting support. Tapered wheel: It is much similar to a straight wheel that tapers outward towards the center of the wheel.

It is stronger than straight wheels with a great acceptance of higher lateral loads. Saucer wheel: It is used to grind milling cutters and twist drills. It is commonly used in non-machining areas. Diamond wheel: A diamond wheel is a grinding wheel with industrial diamonds bonded to the periphery. They can work at angles between 0 and 30 degrees but typically work best for use with grinding angles from 0 to 15 degrees.

The materials in each grinding wheel break down into a few main components — the grains, the bond and the fiberglass that reinforces the wheels to give them strength and stability for use in demanding applications.

The grit of the wheel is also an essential element that helps determine performance. The abrasive grains provide the essential functionality of a grinding wheel because they remove material from the workpiece. A few commonly used grinding wheel abrasives are ceramic alumina, zirconia alumina, aluminum oxide, white aluminum oxide, aluminum oxide and silicon carbide. Grains can be blended together to achieve different performance characteristics as well.

Grains also come in various sizes — the size of a grain refers to the size of the individual abrasive particles, similar to the grades for sandpaper particles. The bond is the substance that causes the abrasive grains to adhere to the wheel. Bonds can consist of different materials. Common materials include shellac, resinoids, rubber and glass or glass-ceramic. At Weiler Abrasives, our portable grinding wheels contain resinoid bonds.

The bond on a grinding wheel may be either hard or soft. A harder bond extends the wheel's lifespan, provided the user operates and maintains the wheel correctly. A softer bond, on the other hand, allows for smoother grinding and exposes new grains more quickly.

Choosing the correct bond for a given application can help balance performance and longevity. The type of metal can also influence the bond that's best for your application.

A grinding wheel's bond sometimes contains iron, sulfur and chlorine, which can pose challenges if they adhere to the workpiece during grinding. Weiler Abrasives offers several wheels that minimize these elements. They help prevent corrosion on stainless steel and aluminum workpieces. The bond on a grinding wheel helps provide a consistent cut rate by exposing new grains over time. As older grains become worn, the grain particles fracture as they are designed to — thereby exposing new abrasive surfaces, leaving fresh abrasive particles exposed in their places.

Ideally, the composition of the binding is such that under normal working conditions, wear and tear will remove worn abrasive particles and leave fresh ones in place, maintaining the wheel's superior cut-rate and performance. The abrasive particles bound to the wheel also have a characteristic known as grade. Grade refers to hardness, but not the hardness of the particles themselves — it refers instead to the strength of the bond holding the particles to the wheel.

A wheel with a stronger bond typically has a longer life. A softer bond is designed to break down faster to maintain a consistent cut rate as new sharp grains take the place of worn ones. The letters N, R, S and T specify the hardness of a bond, with the letters that come later in the alphabet referring to harder bonds. As a general rule, a wheel with a softer bond will perform better on a hard metal, while a hard bond will perform better on a softer metal.

The fiberglass structure and design on a grinding wheel provides reinforcement, rigidity and superior grinding ability. All Weiler grinding wheels come with triple-reinforced fiberglass that gives additional support and strength for aggressive stock removal. Our Tiger brand of performance grinding wheels has the outer layout of fiberglass cut back to allow for aggressive grinding from the outset with no break-in period.

The grit of a wheel is critical for supplying the right abrasion. Grit measurements generally range from coarse to fine. On Weiler Abrasives' grinding wheels, the coarsest grit has a rating of about 24 and the finest grit — the grit on snagging wheels — has a rating of about Selecting the right grit level for a particular application helps ensure sufficient grinding power.
