Grinding wheels – an indispensable tool in the arsenal of any craftsman, be it a professional or an amateur. These abrasive materials are widely used in various fields: from metalworking to woodworking and even in the automotive industry. The correct choice of a grinding wheel and its use can significantly improve the quality and speed of work. In this article We will look at the main types of grinding wheels, their application and give useful tips on choosing.
Main types of circles
1. Flat circles:
Flat grinding wheels, also known as cut-off wheels, are ideal for cutting and grinding various materials. They are used for cutting metal, plastic, and stone. These wheels are highly durable and long-lasting.
2. Petal circles:
Flap wheels consist of multiple abrasive flaps glued to a base. They are widely used for removing burrs, rust, and polishing surfaces. Flap wheels provide uniform processing and last a long time.
3. Cup circles:
Cup grinding wheels are cup-shaped and are used for grinding and cleaning large surfaces. They are especially useful when working with concrete and stone, providing efficient and fast processing.
4. Cone circles:
Cone wheels are used for processing hard-to-reach places and internal surfaces. Their convenient shape allows easy penetration into narrow and deep holes, which makes them indispensable when working with complex-shaped parts.
5. Polishing wheels:
Polishing wheels are used to add shine and finish to a surface. They have a soft base and are often used to polish cars, furniture, and other items.
Application of grinding wheels
Grinding wheels are widely used in various industries:
- Metalworking: Removal of rust, burrs, grinding of welds and preparation of surfaces for painting.
- Woodworking: Sanding wood surfaces, removing old paint and preparing for new coating.
- Automotive industry: Body polishing, removal of scratches and defects, preparation for painting.
Tips for choosing
When choosing a grinding wheel, it is important to consider several key factors:
- Abrasive material: The choice of wheel material depends on the material being processed. For example, aluminum oxide wheels are better suited for metal, and silicon carbide wheels are better suited for stone.
- Grit: Coarse grit wheels are used for rough grinding, while fine grit wheels are used for finishing.
- Bond: Abrasive particles can be held on the wheel by resin, rubber or ceramic. The choice depends on the requirements for wheel rigidity and durability.
Security and safety
When working with grinding wheels, it is important to follow safety rules. Always use safety glasses and a mask to avoid abrasive particles getting into your eyes and respiratory tract. It is also recommended to wear gloves and check the wheels for damage before use.
