What is a grinding wheel? Quality, genuine grinding stones at good prices

Grinding wheels, also known as grinding stones, are familiar tools in the mechanical industry, especially in the field of polishing, grinding or cutting hard materials. Different types of grinding wheels have different applications. In the article "What is a grinding wheel? Types of genuine, quality, good price grinding stones" will decode from A to Z information about grinding stones. Discover now!

1. What is a grinding wheel?

Grinding wheels (grinding stones, grinding discs) are made of abrasive particles and adhesive materials to form a wheel shape. Round is the most common shape, but there are also some other shapes produced such as conical, cup-shaped. Abrasive particles are the main component of grinding wheels and are also divided into two types: natural abrasive particles and artificial abrasive particles, they can be diamonds, ceramics, rubber, ... with diverse applications in grinding stone production. The adhesive material of abrasive particles is usually inorganic or organic.

Grinding wheels are attached to grinding machines, saws that rotate at high speed to perform many different tasks. Hard materials such as metal or steel can also be worn and cut through by grinding wheels.

2. Applications of Grinding Wheels

There are many types of grinding wheels with different shapes and uses:

• Straight grinding wheels are commonly used in bench grinders

• Cylindrical grinding wheels are used in horizontal or vertical grinding machines to produce flat surfaces

• Grinding wheels are characterized by a wider center with a tapered surface. These wheels are used to grind gear teeth or threads

• Straight cup grinding wheels are used to fit into cutting machines and are used to grind tools or produce straight surfaces

• Slim disc grinding wheels have a central part that projects outward at the edge. These wheels are often used to cut holes such as slots

• Disc grinding wheels have a straight edge and are used in spiral mills and grinding cutters

3. Classification of grinding wheels

3.1. Classification by material

Steel grinding wheels: used for rough grinding, grinding metal surfaces such as cast iron, steel, iron, stainless steel, ... thanks to the great destructive power due to the structure of corundum grinding particles

Concrete grinding wheels: suitable for smoothing concrete surfaces and metal surfaces such as steel, iron, stainless steel, ... this type of grinding wheel has a variety of sizes.

3.2. Classification by grinding type

Polishing grinding wheels: To bring aesthetics to the product, polishing grinding wheels are used to polish many surfaces such as iron, steel, stainless steel, wood, glass or concrete.

Fine grinding stones: This type of stone has a smooth surface, used to remove stains, old paint stains, prepare for painting, and apply new varnish to the product surface.

3.3. Classification by grinding diameter

• 100mm diameter is the type of grinding wheel used for machines with a diameter of 100mm, they also have the function of grinding, roughening, smoothing the surface.

• 150mm diameter is this type often uses A30R abrasive grains, creating high grinding, polishing and cleaning stains on the surface effectively

• 200mm grinding wheel is used to grind coarse iron

In addition, on the market there is also a type of grinding wheel made of very hard Cubitron II abrasive grains, this type has a diameter of 3m, has good heat resistance, is durable, and is sharp.

4. Genuine, quality, good price grinding stones

4.1. Diamond Grinding Wheels

Diamond grinding wheels contain abrasive grains made from the hardest material on Earth, resulting in a more durable grinding wheel. This is evident when compared to conventional grinding wheels used on materials like steel or carbide. Diamond wheels are used for grinding non-ferrous materials with high hardness, such as carbide cutting tools, glass, and ceramics.

To avoid burning the surface or cracking the workpiece, diamond grinding wheels must be used correctly to remove material at high speed and with high precision. Some diamond wheels are made from polycrystalline or monocrystalline synthetic diamonds, providing hardness and thermal conductivity equal to (or greater than) natural diamonds.

4.2. CBN Grinding Wheels

CBN (Cubic Boron Nitride) grinding wheels are a superabrasive material that performs better than diamond when grinding ferrous materials (iron-based) with hardness above 40 HRC. While diamond begins to lose its hardness at around 700°C, CBN remains stable above 1,000°C.

Materials such as hard iron-rich components like bearings, hardened steel, and nickel-based alloys are ideal for CBN wheels. Due to its unique properties, CBN grinding wheels provide smooth, uniform surfaces. CBN wheels are used in applications such as cutting tools and surgical blades, compressor parts, and fuel injectors. They are also used to cut various HSS metals, including woodworking tools, cutters, drill bits, and blades.

4.3. CDX Grinding Wheels

Compared to CBN or diamond wheels, CDX grinding wheels are less common. However, they have specialized applications, particularly in grinding tungsten carbide and steel simultaneously. CDX wheels contain a mixture of CBN and diamond powders (C for CBN, D for diamond, and X representing the blend) to grind different materials.

CDX wheels are used to grind tools such as carbide-tipped saw blades, bac-pac systems, and other specialized tools.

5. Factors to Consider When Choosing a Grinding Wheel

5.1. Machine Type

Here are some of the hand tools and stand-alone machines that commonly use grinding wheels.

These include:

• Angle grinders – also known as disc grinders or side grinders, – are used to cut or polish hard materials

• Belt grinders – benchtop grinders that have two different types of grinding wheels on each side, which can sharpen the tool and are used for roughing or finishing

• Cylindrical grinders – used to shape the outside of bars, pipes, or bearings

• Jig grinders – heavy-duty machines used for complex grinding and cutting

• Table saws – sometimes called bench saws – are used for cutting wood

• Cut-off saws – handheld tools used to cut straight through wood

• Petrol cutters – handheld tools used to cut concrete, steel, stone, asphalt, and other materials

Depending on the type of machine, customers can choose the right grinding wheel. AMS distributes a variety of grinding wheels depending on the type of machine your unit is using.

5.2. Notes before choosing a grinding wheel

The operator must note the following points:

• The nature of the material being ground

• How complex is the task

• What is the finishing requirement

• The level of accuracy required

• The contact area

• The speed of the wheel

• If coolant is used

• The power of the machine or spindle used
