The brake disc is a core component of the vehicle’s braking system, converting kinetic energy into heat energy to ensure safe deceleration and stopping.
Among various brake disc materials — cast iron, aluminum alloy, and composite — carbon ceramic composites (CCB) have become the preferred choice for high-performance vehicles due to their light weight, exceptional heat resistance, and superior durability.
However, machining carbon ceramic materials is highly challenging due to their extreme hardness, brittleness, and unique thermal properties.
Conventional abrasives like alumina or silicon carbide cannot effectively process such materials.
Diamond grinding wheels are the only reliable and efficient solution for machining carbon ceramic brake discs, providing superior sharpness, precision, and tool life.
