The Basics of Abrasive Wheels
Abrasive wheels, otherwise known as grinding wheels, are an essential part of most manufacturing and industrial operations. The abrasive wheel is comprised of an abrasive material, usually aluminum oxide or silicon carbide, and a bonding material that holds the abrasive material together. The abrasive wheel is attached to a grinder or cutting tool, which is then used to grind, cut or shape metals, stones and other materials. Abrasive wheels have been used in industry for a variety of tasks since the early 20th century.
Abrasive wheels are used in many applications, ranging from sharpening tools to grinding down concrete surfaces. Generally, these wheels will be made in a range of grit sizes to accommodate the various applications. The grit size of a wheel refers to the coarseness or fineness of the abrasive material on the wheel. The larger the grit size, the coarser the material, while smaller grit sizes result in a finer grain.
When choosing an abrasive wheel, it is important to consider the application it will be used for. Wheels that are too coarse could burn or damage the workpiece, while wheels that are too fine can make it difficult to achieve a smooth or precise finish. Additionally, the type of material being worked with must also be taken into account. Different abrasive materials are better suited for different materials, so it is essential to make sure the wheel is appropriate for the material.
The most common types of abrasive wheels are referred to as conventional wheels, which are resin-bonded and designed for light to medium cutting, grinding and polishing operations. These wheels are best used for small jobs and non-precision tasks. There are also different types of non-conventional abrasive wheels available for specific applications, such as diamond wheels for cutting and grinding hard materials, and glass-bonded wheels for edge grinding.
It is important to take proper safety precautions when working with abrasive wheels, such as wearing safety glasses and protective gloves. The wheel should always be securely mounted and checked for any signs of damage or wear before being used. Additionally, the wheel should be running at the correct speed and should never be forced into the workpiece. Following these safety measures will ensure your grinding and cutting operations are done properly and safely.
Abrasive wheels are an essential part of any grinding and cutting operation, and they can ensure a precise and even finish on any material. With the right wheel, your operations can be done quickly and effectively, resulting in a high-quality finish. Taking the time to choose the correct wheel and follow appropriate safety procedures will ensure your operations are successful and safe.
