Diamond grinding wheels are made using industrial diamond particles as the cutting edge. These wheels are primarily utilized for grinding hard materials, such as ceramic, glass, and various types of metals, due to their unparalleled hardness and durability.
CBN, or Cubic Boron Nitride, grinding wheels contain synthetic abrasive particles of cubic boron nitride. These wheels are especially effective for grinding hardened steels and ferrous metals, making them a popular choice in machining operations.
Diamond is the hardest known natural material, making diamond grinding wheels exceptionally robust. CBN is also very hard, but it typically ranks just below diamond in terms of hardness. This difference can affect their efficacy when used on various materials.
Diamond wheels excel at grinding non-ferrous materials such as ceramics, composites, and graphite. Conversely, CBN wheels are best suited for ferrous materials, including hardened steel and cast iron, which can damage diamond wheels.
CBN grinding wheels provide better thermal stability than diamond wheels. This makes them particularly advantageous when grinding materials that generate significant heat during processing, as they are less likely to deform or lose their cutting ability.
Diamond wheels are generally more expensive than CBN wheels due to the cost of natural diamond materials. However, considering the longer lifespan of diamond wheels when used on appropriate materials, the cost difference may equate over time.
Diamond grinding wheels often use resin, metal, or vitrified bonds, depending on the application and specific grinding requirements. CBN wheels typically use a metal bond that enhances durability and performance for grinding hardened materials.
CBN grinding wheels are often preferred for high-heat applications due to their superior thermal stability. They can maintain their effectiveness without altering the structure of the workpiece, making them a reliable choice for continuous grinding processes.
Maintenance requirements differ between the two types of wheels. Diamond wheels require more care to prevent chipping and ensure longevity, particularly when used on tougher materials. CBN wheels, while still requiring maintenance, can often handle tougher applications with less immediate attention.
Diamond grinding wheels are often considered more versatile because they can handle a wider range of materials. However, for specific applications involving ferrous metals, CBN wheels provide unmatched performance and are thus favored by many professionals in the field.
