DELUN Inox Cutting Discs

Abrasive wheels are used to modify or prepare surfaces (either internal or external). They use abrasive cut-off, face grinding or periphery grinding. They can also be used for cutting, polishing, sanding, deburring and finishing.

The relative resistance, toughness, friability (how self-sharpening they are) and hardness are decided by the type of abrasive material the wheel contains. Some abrasive particles include aluminium, boron and silicon.

The coating or bonding material (organic/inorganic) determines the shape and structure of the abrasive wheel. The bonding material needs to withstand the forces the wheel is subjected to, including centripetal force, shock, friction and high temperatures.

The structure of the abrasive wheel determines the grade and grain spacing as well as the volume. Hard abrasive wheels are usually used on softer materials, while softer abrasive wheels are typically used on harder materials.

Users select the abrasive wheels according to certain criteria. This includes:

• The machine spindle speed.
• The surface type (e.g., wood, metal, stone, etc.).
• The size of the contact area (between the material and the wheel).
• The machine type.
• The wheel state.
