Abrasive wheels are specialized tools used for grinding, cutting, and polishing various materials. They come in different types, each designed for specific applications. Here are some common types of abrasive wheels:
Straight Grinding Wheels: These are the most common type of grinding wheel and are used for surface grinding, snagging, and off-hand grinding operations. They can be mounted on pedestal grinders, bench grinders, and special-purpose machines.
Cylinder or Wheel Rings: They are used for grinding works that require a good finish and accurate dimensions, like grinding threads, gear teeth, cutting internal threads, and sharpening cutting tools.
Tapered Grinding Wheels: These wheels have a slight taper to the side faces. They are used for grinding threads and gear teeth.
Straight Cup Wheels: These wheels have a slightly tapered face for grinding on the periphery and used for tool and cutter grinder operations.
Dish Cup Wheels: They are used for snagging and off-hand grinding of large and small external and internal work.
Diamond Wheels: Diamond wheels are used for grinding carbide cutting tools, gemstones, and concrete. They are highly abrasive and durable.
Mounted Points: These are small grinding wheels mounted on a spindle or mandrel. They are used for internal grinding of small parts, precision grinding, and finishing.
Cut-Off Wheels: Also known as cutting discs, these wheels are thin and used for cutting metal, plastic, and other materials. They are mounted on portable or stationary saws.
Flaring Cup Wheels: These wheels have a larger contact area, making them suitable for grinding large, flat surfaces and for cylindrical grinding.
Snagging Wheels: Snagging wheels are used for heavy-duty grinding of large castings, forgings, and billets.
Rubber Bonded Abrasive Wheels: These wheels are made by mixing abrasive grains with rubber and are used for polishing and finishing delicate surfaces.
Grinding Cones and Plugs: These are abrasive wheels shaped like a cone or plug for grinding in tight spaces or irregular surfaces.
Flap Wheels: These consist of abrasive flaps attached radially to a central hub. They are used for blending, deburring, and finishing applications.
Wire Brushes: While not technically abrasive wheels, wire brushes are used for cleaning, deburring, and surface preparation. They consist of metal wires or abrasive nylon filaments.
It's essential to choose the right type of abrasive wheel for the specific task to ensure safety and efficiency in the grinding or cutting process. Always follow the manufacturer's guidelines and safety instructions when using abrasive wheels.
