Grinding Wheel

Primarily, grinding wheels are used for grinding purposes. Typical uses include deburring, automotive bodywork, metal grinding, rust removal, surface preparation, weld spatter removal, metal fabrication, and swift stock removal.

We also offer hybrid grinding wheels, uniquely thinner than standard grinding wheels yet thicker than cut-off wheels. These hybrid wheels are adept at both cutting through materials like rebar and metal tubing and grinding the same metals, offering versatility and continuity in work without the need to switch between different discs.

Type 27 (T27) grinding wheels feature a depressed center and are flat-faced, similar to Type 27 flap discs. Conversely, Type 29 flap discs have a curved shape and are suitable for steeper angle work.

Type 1 (T1) straight wheels have a completely flat surface, front and back. They are commonly used with cutting discs or for both large and small grinding wheels in pedestal or bench grinders.

Different grinding tasks require specific types of abrasive materials. Common choices for grinding wheels are aluminum oxide and silicon carbide grains, which are effective for working with a variety of metal surfaces. For example, aluminum oxide is particularly suited for grinding steel, stainless steel, iron, and other ferrous metals.

Our advanced grinding wheels also cater to softer metals such as aluminum, brass, copper, bronze, and other non-ferrous metals. Grinding these metals can be challenging due to their lower melting points. We use a specialized blend of aluminum oxide and silicon carbide grains in our wheels designed for soft metals. This blend prevents loading and minimizes heat generation, allowing for safer and more efficient grinding.

While they may appear similar, grinding and cutting wheels have distinct functions. Grinding discs are thicker, enhancing their durability and suitability for grinding metal.

In contrast, cutting discs are thinner, designed specifically for cutting through metal. Using a cutting wheel for grinding can be unsafe and damage the tool.

It’s crucial to adhere to safety guidelines when using high-speed abrasive discs:

• Always wear appropriate personal protective equipment (PPE).
• Inspect the grinding wheel for any damage, cracks, or chips before use.
• Ensure the grinding wheel’s diameter matches the angle grinder.
• Do not alter or remove the angle grinder guard.
• Only use angle grinders with RPM ratings appropriate for the wheel.
• Allow the grinder to reach full speed before use and let it stop completely after use.
• Maintain a firm two-handed grip on the angle grinder.
• Avoid wearing loose clothing while operating the grinder.

By following these safety measures, you can ensure a secure and efficient grinding experience.

The lifespan of a grinding wheel depends on various factors like the type of material being ground, the pressure applied, and the frequency of use. Generally, a wheel should be replaced when it’s worn down to about half its original diameter or if it shows any signs of damage or irregular wear.

The grit size depends on the desired finish and the material being worked on. Coarser grits (lower numbers) are used for rapid material removal and rough grinding, while finer grits (higher numbers) are for smoother finishes and precision work. For example, use a coarser grit for removing rust or paint and a finer grit for finishing and sharpening.

While some grinding wheels are versatile, it’s important to use a wheel designed for the specific material you’re working with. Using the wrong type can lead to ineffective grinding or even damage the wheel and the material. For instance, wheels designed for metal should not be used on wood.

Store grinding wheels in a dry, cool place away from direct sunlight and extreme temperatures. Keep them in their original packaging to prevent any impact damage. Do not stack heavy objects on top of the wheels as this could cause cracks or warping.

Using a dust extraction system or a grinder with a dust collection feature can significantly reduce dust and debris. Additionally, wearing appropriate PPE like masks and goggles is essential for safety.

No, each grinding wheel has a maximum operating speed, often indicated on the wheel itself. Exceeding this speed can be extremely dangerous as the wheel might shatter. Always match the wheel speed with the grinder’s speed rating.
