Our silicon carbide abrasive cup brush is purpose-built for deburring precision vacuum pump rotors. Tough silicon carbide filaments efficiently clear machining burrs, sharp edges and residual metal scraps on complex curved surfaces and groove positions. It features moderate cutting power to avoid over-grinding and surface damage on high-precision rotors. Compatible with CNC machining centers and automatic finishing equipment, it delivers consistent finishing results in mass production. This brush optimizes rotor surface smoothness, helps improve vacuum sealing performance and extends the service life of vacuum pump equipment.
